Except where the context otherwise indicates and for the purpose of this annual report only:

This annual report contains information and statistics relating to China’s economy and its education industry derived from various publications issued by market research companies and PRC governmental entities, which have not been independently verified by us. The information in such sources may not be consistent with other information compiled in or outside China.

This annual report contains forward-looking statements that involve risks and uncertainties. All statements other than statements of historical facts are forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements. These statements are made under the “safe harbor” provisions of the U.S. Private Securities Litigations Reform Act of 1995.

You can identify these forward-looking statements by words or phrases such as “may,” “will,” “expect,” “anticipate,” “aim,” “estimate,” “intend,” “plan,” “believe,” “likely to” or other similar expressions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements include, but are not limited to, statements about:

You should read this annual report and the documents that we refer to in this annual report and have filed as exhibits to this annual report completely and with the understanding that our actual future results may be materially different from and worse than what we expect. Other sections of this annual report discuss factors which could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. New risk factors and uncertainties emerge from time to time and it is not possible for our management to predict all risk factors and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We qualify all of our forward-looking statements by these cautionary statements.

You should not rely upon forward-looking statements as predictions of future events. The forward-looking statements made in this annual report relate only to events or information as of the date on which the statements are made in this annual report. Except as required by law, we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events.

Sunlands Technology Group is a Cayman Islands holding company. It conducts its operations in China through its PRC subsidiaries and consolidated variable interest entities, or the VIEs. However, we and our direct and indirect subsidiaries do not, and it is virtually impossible for them to, have any equity interests in the VIEs in practice as current PRC laws and regulations restrict foreign investment in companies that engage in value-added telecommunication services. As a result, we depend on certain contractual arrangements with the VIEs to operate a significant portion of our business. This structure allows us to exercise effective control over the VIEs, and is designed to replicate substantially the same economic benefits as would be provided by direct ownership. The VIEs are owned by certain nominee shareholders, not us. Most of the nominee shareholders of the VIEs are also beneficial owners of our company. Investors in our ADSs are purchasing equity securities of a Cayman Islands holding company rather than equity securities issued by our subsidiaries and the VIEs. Investors who are non-PRC residents may never directly hold equity interests in the VIEs under current PRC laws and regulations. As used in this annual report, “we,” “us,” “our company,” “our,” or “Sunlands” refers to Sunlands Technology Group and its subsidiaries, and, in the context of describing our consolidated financial information, business operations and operating data, our consolidated VIEs, “variable interest entities” or “VIEs” refers to Beijing Shangde Online Education Technology Co., Ltd., or Beijing Sunlands, Wuhan Xiaoyan Technology Co., Ltd., or Wuhan Xiaoyan, Wuhan Jiayan Online Education Technology Co., Ltd., or Wuhan Jiayan, Beijing Odysseus Education Technology Co., Ltd., or Beijing Odysseus, Wuhan Hadeliang Online Education Technology Co., Ltd., or Wuhan Hadeliang, Tianjin Shangde Online Education Technology Co., Ltd., or Tianjin Shangde, Wuhan Fangtang Education Technology Co., Ltd., or Wuhan Fangtang, Beijing Zhiziyuanshui Education Technology Co., Ltd., or Beijing Zhiziyuanshui, Beijing Feibian Education Technology Co., Ltd., or Beijing Feibian, and Beijing Lingding Management Consulting Co., Ltd., or Beijing Lingding. The VIEs primarily conduct operations in China. The VIEs are consolidated for accounting purposes but are not entities in which we own equity. Our Company does not conduct operations by ourselves.

Our corporate structure involves unique risks to investors in the ADSs. In 2019, 2020 and 2021, the amount of revenues generated by the VIEs accounted for 93.4%, 47.3% and 21.4%, respectively, of our total net revenues. As of December 31, 2020 and 2021, total assets of the VIEs, excluding amounts due from other consolidated entities in the our company, equaled to 32.7% and 33.6% of our consolidated total assets as of the same dates, respectively. Our contractual arrangements with the VIEs have not been tested in court. If the PRC government deems that our contractual arrangements with the VIEs do not comply with PRC regulatory restrictions on foreign investment in the relevant industries, or if these regulations or the interpretation of existing regulations change in the future, we could be subject to material penalties or be forced to relinquish our interests in those operations or otherwise significantly change our corporate structure. We and our investors face significant uncertainty about potential future actions by the PRC government that could affect the legality and enforceability of the contractual arrangements with the VIEs and, consequently, significantly affect our ability to consolidate the financial results of the VIEs and the financial performance of our company as a whole. Our ADSs may decline in value or become worthless if we are unable to effectively enforce our contractual control rights over the assets and operations of the VIEs that conduct a significant portion of our business in China. See “Item 3. Key Information—3.D. Risk Factor—Risks Related to Our Corporate Structure” for detailed discussion.

As part of a continued regulatory focus in the United States on access to audit and other information currently protected by national law, in particular China’s, the Holding Foreign Companies Accountable Act, or the HFCAA has been signed into law on December 18, 2020. The HFCAA states if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspection for the PCAOB for three consecutive years beginning in 2021, the SEC shall prohibit our ADS from being traded on a national securities exchange or in the over-the-counter trading market in the U.S. Further, the potential enactment of the Accelerating Holding Foreign Companies

Accountable Act would decrease the number of non-inspection years from three years to two. Accordingly, this could happen in 2024 under the current law, or in 2023 if the Accelerating Holding Foreign Companies Accountable Act were enacted. If our ADSs were delisted from the exchange and prohibited from over-the-counter trading in the U.S.,there is no certainty that we will be able to list our ADSs on a non-U.S. exchange or that a market for our shares will develop outside of the U.S. The delisting of our ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.

According to the HFCAA Determination Report issued by PCAOB on December 16, 2021, our auditor is subject to the determinations that the PCAOB is unable to inspect or investigate completely. In March 2022, the SEC issued its first “conclusive list of issuers identified under the HFCAA” indicating that those companies are now formally subject to the delisting provisions if they remain on the list for three consecutive years. We anticipate being added to the list shortly after the filing of this annual report on Form 20-F. See “Item 3. Key Information—3.D. Risk Factor—Risks Related to Doing Business in China—Our ADSs will be delisted and our ADSs and shares will be prohibited from trading in the over-the-counter market under the Holding Foreign Companies Accountable Act, or the HFCAA, if the PCAOB is unable to inspect or fully investigate auditors located in China” for detailed discussion.

We face various legal and operational risks and uncertainties as a company based in and primarily operating in China. The PRC government has significant authority to exert influence on the ability of a China-based company, like us, to conduct its business, accept foreign investments or be listed on a U.S. stock exchange. For example, we face risks associated with regulatory approvals of offshore offerings, anti-monopoly regulatory actions, cybersecurity and data privacy, as well as the lack of inspection from the U.S. Public Company Accounting Oversight Board, or PCAOB, on our auditors. The PRC government may also intervene with or influence our operations as the government deems appropriate to further regulatory, political and societal goals. The PRC government has recently published new policies that significantly affected educational industry and we cannot rule out the possibility that it will in the future further release regulations or policies regarding educational industry that could adversely affect our business, financial condition and results of operations. Any such action, once taken by the PRC government, could cause the value of such securities to significantly decline or in extreme cases, become worthless.

You should carefully consider all of the information in this annual report before making an investment in the ADSs. Below please find a summary of the principal risks and uncertainties we face, organized under relevant headings. In particular, as we are a China-based company incorporated in the Cayman Islands, you should pay special attention to subsections headed “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China” and “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Corporate Structure.”

Investing in the ADSs involves significant risks. You should carefully consider all of the information in this annual report before making an investment in the ADSs. Below please find a summary of the principal risks we face, organized under relevant headings.

If we fail to increase student enrollments, our net revenues may decline, and we may not be able to maintain growth.

We generate revenue primarily from the tuition we collect from our students. It is critical for us to enroll prospective students in a cost-effective manner. Some of the factors, many of which are largely beyond our control, could prevent us from successfully increasing enrollments of new students in a cost-effective manner, or at all. These factors include, among other things, (i) reduced interest in the degrees, diplomas, professions or certifications for which our course offerings are designed; (ii) negative publicity or perceptions regarding us, or online education services in general; (iii) the emergence of alternative course delivery models; (iv) the inability of students to pay the tuition; (v) increasing market competition, particularly price reductions by competitors that we are unable or unwilling to match; and (vi) adverse changes in relevant government policies or general economic conditions. If one or more of these factors reduce market demand for our services, our student enrollments could be negatively affected or our costs associated with student acquisition and retention could increase, or both, any of which could materially affect our ability to grow our gross billings and net revenues. These developments could also harm our brand and reputation, which would negatively impact our ability to expand our business.

If we fail to manage our business growth effectively, the success of our business model will be compromised.

Our growth strategy has placed, and will continue to place, a significant strain on our sales and marketing capacities, administrative and operating infrastructure, facilities and other resources. To maintain our growth, we need to continue to acquire more students, scale up our course offerings, increase our academic and administrative faculty, as well as strengthen our platforms and systems. We will also be required to refine our operational, financial and management controls and reporting systems and procedures. If we fail to efficiently manage our business expansion, our costs and expenses may increase more than we plan and we may not successfully attract a sufficient number of students and qualified academic and administrative faculty in a cost-effective manner, respond to competitive challenges, or otherwise execute our business plans. In addition, we may, as part of carrying out our growth strategies, adopt new initiatives to offer additional course packages and educational content and to implement new pricing models and strategies. We cannot assure you that these initiatives may achieve the anticipated results. These proposed changes may not be well received by our existing and prospective students, in which case their experience with our education services may suffer, which could damage our reputation and business prospect.

Our ability to effectively implement our strategies and manage our business growth will depend on a number of factors, including our ability to: (i) identify and effectively market our products and services in new markets with sufficient growth potential; (ii) develop and improve course offerings and educational contents to make them appealing to existing and prospective students, including working adult students; (iii) maintain and increase our student enrollments; (iv) effectively recruit, train and motivate a large number of new employees, including our faculty members and sales and marketing personnel; (v) successfully implement enhancements and improvements to the systems and platforms; (vi) continue to improve our operational, financial and management controls and efficiencies; (vii) protect and further develop our intellectual property rights; and (viii) make sound business decisions in light of the scrutiny associated with operating as a public company. These activities require significant capital expenditures and investment of valuable management and financial resources, and our growth will continue to place significant demands on our management. There are no guarantees that we will be able to effectively manage any future growth in an efficient, cost-effective and timely manner, or at all. Our growth in a relatively short period of time is not necessarily indicative of results that we may achieve in the future. If we do not effectively manage the growth of our business and operations, our reputation, results of operations and overall business and prospects could be negatively impacted.

Our net revenues were RMB2,193.9 million, RMB2,203.8 million and RMB2,507.8 million (US$393.5 million), respectively, in 2019, 2020 and 2021. During the same periods, our gross billings were RMB2,358.5 million, RMB2,350.4 million and RMB1,970.0 million (US$309.1 million), respectively, and our new student enrollments were 363,013, 434,240 and 434,228, respectively. We are seeking to offer a broader range of courses, foster a more social and entertaining learning experience, and use cutting-edge technologies, particularly artificial intelligence, to improve students’ learning experience and outcomes. All of these endeavors involve risks and will require significant management, financial and human resources. We cannot assure you that they will achieve the anticipated results or that our gross billings and new student enrollments will not decline in the future due to the risks and uncertainties discussed in this “Item 3.D. Risk Factors.” If we are not able to achieve growth in our gross billings and new student enrollments effectively, or at all, our business and prospects may be materially and adversely affected.

We have a history of net losses and we may not continue to achieve profitability in the future.

We had net losses of RMB395.2 million and RMB431.0 million in 2019 and 2020, respectively, and net profit of RMB212.4 million (US$33.3 million) in 2021. We cannot assure you, however, that we will be able to continue to generate net profits in the future.

We intend to continue to invest heavily for the foreseeable future in increasing our market share, improving the capacity of our technology infrastructure to better support an even larger student base and to offer additional courses and educational content.

These efforts may be more costly than we expect and our net revenues may not increase sufficiently to offset these expenses. We may continue to take actions and make investments that do not generate optimal short-term financial results and may even result in increased operating losses in the short term with no assurance that we will eventually achieve our intended long-term benefits or profitability. These factors, among others set out in this “Item 3.D. Risk Factors,” may negatively affect our ability to achieve profitability in the near term, if at all.

If we are unable to conduct sales and marketing activities cost-effectively, our results of operations and financial condition may be materially and adversely affected.

We rely on our sales and marketing efforts to increase student enrollments. Our sales and marketing expenses primarily include expenses incurred in relation to sales and marketing personnel and marketing spending. We incurred approximately RMB1,792.3 million, RMB2,123.6 million and RMB1,748.4 million (US$274.4 million), respectively, in sales and marketing expenses in 2019, 2020 and 2021.

Our sales and marketing activities may not be well received by the market and may not result in the levels of sales that we anticipate. We also may not be able to retain or engage a sufficient number of experienced sales and marketing personnel, or to train newly onboard sales and marketing personnel, which we believe is critical to implementing our sales and marketing strategies cost-effectively. Further, sales and marketing approaches and tools in China’s online education market are evolving rapidly. This requires us to continually enhance our sales and marketing approaches and experiment with new methods to keep pace with industry developments and student preferences. Moreover, our sales and marketing activities may be deemed to violate PRC laws and regulations, and we may be exposed to administrative penalties, such as paying fines or publishing explanatory notes to limit the adverse effects of our marketing efforts. If we are deemed guilty of significant infringements, we may be ordered to cease sales and marketing activities temporarily and our business license may be revoked. Failure to engage in sales and marketing activities in a compliant and cost-effective manner may reduce our market share, cause our revenues and gross billings to decline, negatively impact our profitability, and materially harm our business, financial condition and results of operations.

We may be adversely affected by any negative publicity concerning us and our business, shareholders, affiliates, directors, officers and employees and the industry in which we operate, regardless of its accuracy, that could harm our reputation and business.

Negative publicity about us and our business, shareholders, affiliates, directors, officers, and teachers and other employees, as well as the industry in which we operate, can harm our operations. We have been exposed to negative publicity concerning refund dispute, administrative penalty, alleged improper or misleading statement made in our sales and marketing activities, and student recruitment for unqualified institutions in the past. For example, we were reported to have recruited students from January 2021 to January 2022 for Morrison University in the state of Nevada. The recruitments were made pursuant to our cooperation with a company in China (the “Partnering Company”) claiming to have obtained authorization from Morrison University. It was revealed that the authorization was inauthentic and Morrison University had no legal right to operate within the state of Nevada. As of the date of this annual report, we are seeking to hold the Partnering Company liable through legal actions. The negative publicity surrounding this incident has and may in the future harm our reputation. We may be involved in disputes with the affected students, especially if we are not able to fulfil our obligations under the agreements between us and the students. While we endeavor to ensure that the overseas institutions with whom we partner are qualified, we cannot assure you that our partnering institutions will timely renew their necessary licenses or qualifications when they become due or that we will be able to identify any unqualified institutions accurately in a timely manner or at all.

Negative publicity concerning these parties could be related to a wide variety of matters, including, but are not limited to:

In addition to traditional media, there has been an increasing use of social media platforms and similar devices in China, including instant messaging applications, such as Weixin/WeChat, social media websites and other forms of internet-based communications that provide individuals with access to a broad audience of consumers and other interested persons. The availability of information on instant messaging applications and social media platforms is virtually immediate as is its impact without affording us an opportunity for redress or correction. The opportunity for dissemination of information, including inaccurate information, is seemingly limitless and readily available. Information concerning our company, shareholders, directors, officers and employees may be posted on such platforms at any time. The risks associated with any such negative publicity or incorrect information cannot be completely eliminated or mitigated and may materially harm our reputation, business, financial condition and results of operations.

We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.

Wuhan Shangde Online Education Technology Co., Ltd., or Wuhan Shangde, our wholly owned subsidiary, and Beijing Sunlands and a number of other VIEs, through which we operate our online education business, currently do not hold a private school operating permit, and we may be subject to risks of administrative sanctions due to our lack of such permit.

On November 7, 2016, China’s National People’s Congress passed an amendment to the Promotion of Private Education Law, or the Amendment, which became effective on September 1, 2017. The Amendment applies different regulatory requirements to non-profit and for-profit private schools.

In December 2016, several PRC government agencies, including the MOE, the State Administration for Industry and Commerce which has now merged into the newly-established State Administration for Market Regulation, or the SAMR), and the Ministry of Human Resources and Social Welfare, jointly promulgated the Implementation Rules on the Supervision and Administration of For-profit Private Schools, or the Implementation Rules. Under the Implementation Rules, the establishment, division, merger or any other material change in a for-profit private school shall be approved by the competent education authorities or the authorities in charge of labor and social welfare and be registered with the competent local branch of SAMR, and a duly approved private school will be granted a private school operating permit. The Implementation Rules also provide that the provisions contained therein should be applicable to “for-profit private training institutions” in an analogous manner. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulation Relating to Private Education—The Law for Promoting Private Education and its Implementing Rules.”

As of the date of this annual report, we have not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to our lack of a private school operating permit for our online education services. In April 2021, the State Council promulgated the Amended Regulations on the Implementation of Law for Promotion Private Education Law of PRC, or Amended Implementing Rules, which became effective on September 1, 2021. The Amended Implementing Rules provide, among others, that a private school engaging in online education activities using

internet technology shall obtain an appropriate private school operating permit. The Amended Implementing Rules, however, do not specify whether an online tutoring service provider like us shall obtain such private school operating permit and what requirements that an online tutoring service provider like us need to satisfy in order to obtain a private school operating permit, nor does it specify which level of government authority has the authority to accept and examine our application for the private school operating permit. According to the Q&A published on the official website of Beijing Municipal Education Commission in April 2020, the education department is only responsible for the registration and approval of institutions providing academic subjects tutoring services for primary and secondary school, and is not responsible for the registration and approval of institutions providing other tutoring services. We cannot assure you that the PRC government will not in the future require us to obtain a private school operating permit. If the PRC government requires us to obtain a private school operating permit or introduces additional amendments and guidelines to expand the coverage of the Amendment or Amended Implementing Rules to explicitly cover online education service providers, and if we fail to do so, we may be subject to fines up to five times the illegitimate gains generated from the provision of training services without a proper license, other administrative sanctions, such as being ordered to refund tuition payments to the students, or criminal liabilities, for our lack of a private school operating permit. We may also be subject to regulatory requirements that are more stringent than the ones currently applicable to us, including those relating to sales and marketing, courses and educational content offerings, teachers’ qualification, as well as tuition fee rates and tuition refund policies, or laws and regulations that require us to obtain and maintain additional licenses and permits, and we may incur substantial expenses or alter or change our business to comply with these requirements. For example, pursuant to the Interim Measures of Wuhan for the Administration of Private Training Institutions promulgated by Wuhan Municipal Government effective on March 15, 2018, private training institutions shall abide by the following provisions with respect of refund fees: (i) if a student requires a refund before the beginning of the course, the institution shall refund all the fees paid to it with deduction of the educational service fees and other fees actually incurred; (ii) if a student requires a refund after the beginning of the course, the institution shall refund the remaining part of the fees after deducting the corresponding proportion of the tuition fees, the fees for collection and management and the relevant taxes and fees in accordance with the proportion of the class hours completed; (iii) where an institution fails to fulfill the commitments with the student, and the student requires a refund, the institution shall refund all the fees paid by the student; and (iv) the institution shall complete the examination and verification within three working days upon the receipt of the refund requirement and shall refund to the student within 30 days. It is uncertain as to whether and how such measures and rules would be applicable to us, and whether any future laws and regulations with respect to the tuition refund requirements for online education service providers like us will be introduced. We have been exposed to refund dispute between us and our students in the past. We cannot assure you that if we are subject to more stringent refund regulatory requirements, we can adjust our refund policy to comply with these requirements on a timely manner, which may cause us more refund disputes with our students and may have a material and adverse effect on our business, operating results and financial condition.

Under the Amendment and the Implementation Rules, a material change in a for-profit private school shall be approved by the competent education authorities or the authorities in charge of labor and social welfare before it can be registered with the competent local branch of SAMR. If we were required to expand the authorized scope of our business license to cover our business of online education services, which shall be registered with the SAMR, to comply with applicable licensing requirements, we may not able to do so before we have obtained a private school operating permit. If any of the foregoing were to happen, our business operations may be disrupted, and our financial condition, results of operations and reputation may be materially and adversely affected.

Moreover, the MOE, jointly with certain other PRC government authorities, promulgated the Opinions on Guiding and Regulating the Orderly and Healthy Development of Educational Mobile Apps on August 10, 2019, or the Opinions on Educational Apps, which requires, among others, mobile apps that offer services for school teaching and management, student learning and student life, or home-school interactions, with school faculty, students or parents as the main users, and with education or learning as the main application scenarios, be filed with the competent provincial regulatory authorities for education before the end of 2019. In addition, on November 11, 2019, MOE issued the Administrative Measures on Filing of Educational Mobile Apps, which requires, among others, that educational mobile app providers shall file their educational mobile apps and that filings of existing educational mobile apps shall be completed before January 31, 2020. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations on Online and Distance Education.” Our educational mobile apps Shangde Jigou and Shangde Zikao had been filed with competent regulatory authority as required under the Opinions on Educational Apps. However, in order to implement the requirements under the Opinions on Further Alleviating the Burden of Homework and After-School Tutoring for Students in Compulsory Education, the education authorities require the re-filing of educational mobile Apps. As of the date of this annual report, we have completed the re-filing procedure of Shangde Zikao and Shangde Jigou. As the Opinions on Educational Apps are relatively new and evolving, we cannot assure you that we are in full compliance with all relevant rules and will be able to complete or maintain such filing in relation with any of our new apps and comply with other regulatory requirements under the Opinions on Educational Apps in a timely manner, or at all. For example, the filings of certain of our educational mobile apps, such as Feibian Jiaoyu,

Jixiang Jiaoyu, Fangtang Youke and Sanjing Shuhua, have not been completed. If we fail to promptly complete such filing and comply with other applicable regulatory requirements, we may be blacklisted by the MOE or its local counterparts and prohibited from submiting any filings for six months, or may be subject to fines, regulatory orders to suspend our operations or other regulatory and disciplinary sanctions.

In addition to the existing regulatory regime, it is uncertain whether and how the PRC government would promulgate additional laws and regulations regarding the online education industry, and there is no assurance that we can comply with any such newly promulgated laws and regulations in a timely manner, or at all. Our failure to fully comply with these existing and future laws and regulations may materially and adversely affect our business, financial condition and results of operations.

Significant uncertainties exist in relation to the interpretation and implementation of, or proposed changes to, the PRC laws, regulations and policies regarding the education industry.

The PRC private education industry, especially the after-school tutoring sector, has experienced intense scrutiny and has been subject to significant regulatory changes recently. In particular, the Opinions on Further Alleviating the Burden of Homework and After-School Tutoring for Students in Compulsory Education jointly promulgated by the General Office of State Council and the General Office of Central Committee of the Communist Party of China on July 24, 2021, or the Alleviating Burden Opinion, sets out a series of operating requirements on after-school tutoring institutions. Furthermore, on August 18, 2021, the Beijing Municipality Government and the Beijing Municipal Committee of the Communist Party of China jointly published the full text of the Beijing Municipality’s Measures to Further Reduce the Burden of Homework and After-School Tutoring on Students in Compulsory Education in Beijing, or the Beijing Measures, to implement the Alleviating Burden Opinion.

As of the date of this annual report, our business, financial condition, results of operations and prospect have not been materially and adversely affected by the scrutiny on the PRC private education industry. It is uncertain whether and how the PRC government would promulgate additional laws, regulations and guidance regarding the education industry and apply more stringent social and ethical standards to those promulgated laws, regulations and guidance in the education sector in general. We are closely monitoring the evolving regulatory environment and will make efforts to seek guidance from and cooperate with the government authorities to comply with laws, regulations and policies, if applicable to our business. Due to the complexity and substantial uncertainty of the regulatory environment, we cannot assure you that we could be in full compliance with newly promulgated laws and regulations or other applicable laws, regulations and policies in a timely manner, or at all. Failure to regain compliance may subject us to fines or other penalties or be required to terminate certain operations, in which case our business, financial condition and results of operations could be materially and adversely affected further.

We face regulatory risks and uncertainties associated with our teachers’ lack of teaching licenses.

Pursuant to the Amended Implementing Rules and the Implementation Rules, the teachers employed by a for-profit private school shall obtain the teaching licenses or relevant professional skill qualifications required by PRC laws and regulations, although the definition or the scope of the “relevant professional skill qualifications” is not explicitly stated in the Implementation Rules. A substantial majority of our teachers currently do not hold teaching licenses.

As of the date of this annual report, we have not received any notice of warning or been subject to any penalties or disciplinary action from government authorities due to the lack of teaching licenses. The current PRC laws and regulations, including the Amendment, the Amended Implementing Rules and the Implementation Rules, remain unclear as to whether the teachers of an online education service provider who provides non-diploma post-secondary and professional education like us are required to obtain and hold teaching licenses. We cannot assure you that the PRC government authorities will not take a contrary view. In the event that in the future our teachers are required by laws to obtain teaching licenses, we cannot assure you that they can meet the requirements for applying for teaching licenses. If our teachers are not able to apply for and obtain the teaching licenses on a timely basis, or at all, we may be ordered to rectify such noncompliance or subject to penalties under the then-effective PRC laws and regulations, in which case our business may be disrupted, and our financial condition, reputation and prospects would be materially and adversely affected.

We face regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs.

On December 20, 2007, the State Administration of Press Publication Radio Film and Television, or SAPPRFT, and the Ministry of Industry and Information Technology, or MIIT, jointly promulgated the Administrative Provisions on Internet Audio Visual Program Services, or the Audio Visual Program Provisions, which became effective on January 31, 2008 and were amended on August 28, 2015. Among other things, the Audio Visual Program Provisions stipulate that no entities or individuals may provide Internet audio-visual program services without a License for Online Transmission of Audio-Visual Programs issued by SAPPRFT or completing the relevant filing with SAPPRFT or its local bureaus, and only state-owned or state-controlled entities are eligible to apply for a License for Online Transmission of Audio Visual Programs. On April 1, 2010, SAPPRFT promulgated the Provisional Implementations of Tentative Categories of Internet Audio Visual Program Services, or the Categories, which clarified the scope of Internet audio-visual programs services, which was amended on March 10, 2017. According to the Categories, there are four categories of Internet audio-visual program services which are further divided into seventeen sub-categories. Sub-category No. 3 to the second category covers the making and editing of certain specialized audio-visual programs concerning, among other things, educational content, and broadcasting such content to the general public online. Sub-category No. 5 of the first category and sub-category No. 7 of the second category cover the live broadcasting of important political, martial, economic, social, cultural, sports activities or events or general social or community cultural activities, sports games and other organized activities. However, there are still significant uncertainties relating to the interpretation and implementation of the Audio Visual Program Provisions, in particular, the scope of “internet audio-visual programs.” See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations Relating to Online Transmission of Audio-Visual Programs.”

We deliver our courses in live streaming format. Our teachers and students communicate and interact live with each other via our virtual learning community. The audio and video data are transmitted through the platforms between specific recipients instantly without any further redaction. We believe the nature of the raw data we transmit distinguishes us from general providers of internet audio-visual program services, such as the operator of online video websites, and the provision of the Audio-Visual Program Provisions are not applicable with regard to our offering of the courses. However, we cannot assure you that the competent PRC government authorities will not ultimately take a view contrary to our opinion. In addition, we also offer video recordings of live streaming courses and certain other audio-video contents on our online platforms to our students as supplementary course materials. If the government authorities determine that our offering of the courses fall within the relevant category of Internet audio-visual program services under the Categories, we may be required to obtain the License for Online Transmission of Audio Visual Programs.

The Categories describe “Internet audio-visual program services” in a very broad, vague manner and are unclear as to whether online courses, whether delivered in a live streaming format or through video recordings, fall into the definition of audio-visual programs. We have made inquiries to the relevant bureaus of SAPPRFT and were informed that online educational content provided through live streaming or recorded courses does not fall within the scope of internet audio-visual programs, the transmission of which does not require a License for Online Transmission of Audio-Visual Programs. We cannot assure you that the PRC government will not ultimately take a view that live streaming or recorded courses or any other content offered on our platforms are subject to the Audio Visual Program Provisions. We currently do not hold a License for Online Transmission of Audio Visual Programs, and since we are not a state-owned or state-controlled entity, we are not eligible to apply for such license. If the PRC government determines that our content should be considered as “internet audio-visual programs” for the purpose of the Audio-Visual Program Provisions, we may be required to obtain a License for Online Transmission of Audio Visual Programs. We are, however, not eligible apply for such license since we are not a state-owned or state-controlled entity. If this were to occur, we may be subject to penalties, fines, legal sanctions or an order to suspend the provision of our live streaming courses. As of the date of this annual report, we have not received any notice of warning or been subject to penalties or other disciplinary action from the relevant governmental authorities regarding the lack of a License for Online Transmission of Audio Visual Programs in conducting of our business.

Our failure to obtain and maintain other approvals, licenses, permits or filings applicable to our business could have a material adverse impact on our business, financial conditions and results of operations.

A number of PRC regulatory authorities, such as the SAMR, the Cyberspace Administration of China, the MITT, the SAPPRFT, and the State Council Information Office, the Ministry of Civil Affairs, and the Ministry of Human Resources and Social Welfare, oversee different aspects of our business operations, and we are required to obtain a wide range of government approvals, licenses, permits and filings in connection with our operations.

We currently do not hold several approvals, licenses and permits that are required for certain aspects of our business operations. Under the current PRC laws and regulations, the provision of our educational content through our online platform

may be considered “online publishing” and may require us to obtain an Internet Publishing License, which we currently do not have. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations Relating to Online Publishing.” As of the date of this annual report, we have submitted an application to the competent government authorities for the approval of an Internet Publishing License. However, we may not be able to receive the approval for such licenses in a timely manner, or at all.

One of our subsidiaries, Wuhan Shangde, has registered “online educational training” in its authorized scope of business. However, the VIEs, and certain of their operating subsidiaries currently do not include “occupational training” and “educational facilitation services” in their authorized scope of business. Based on our consultation with the competent government authorities in Beijing, such government authorities currently may not accept applications for inclusion of “occupational training,” “educational facilitation services” or similar items in the scope of business of companies that do not hold a private school operating permit. For additional information about the private school operating permit, see “—We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.” Even if our application were to be accepted, there is no assurance that it will be approved by the government authorities in a timely fashion, or at all. If it comes to the attention of the government authorities that the VIEs and their operating subsidiaries are operating beyond their respective authorized scope of business, we may be subject to fines, confiscation of the gains derived from the noncompliant operations, or may be required to cease the VIEs’ noncompliant operations. In addition, we deliver courses in live streaming format on our proprietary live streaming platform which the relevant authorities may regard as a live-streaming platform and may thus require us to make necessary filings as a live-streaming platform. See “Item 4. Information on the Company—4.B. Business Overview—Regulations—Regulations Relating to Internet Live Streaming Services.”

As of the date of this annual report, we have not been subject to any fines or other form of regulatory or administrative penalties or sanctions due to the lack of any the above-mentioned approvals, licenses or, permits or filings. However, we cannot guarantee that the government authorities will not impose any penalties or sanctions on us in the future, which may include warnings, fines, mandates to remedy any violations, confiscation of the gains derived from the services for which approvals, licenses, permits or filings are required, and/or an order to cease to provide such services. In addition, we cannot guarantee that the government will not promulgate new laws and regulations that require additional licenses, permits, approvals and/or filings for the operation of any of our existing or future business. If we are unable to obtain such licenses, permits, approvals or filings in a timely fashion, we could be subject to penalties and operational disruption and our financial condition and results of operations could be adversely affected.

We may not be able to continue to recruit, train and retain a sufficient number of qualified faculty members.

Our faculty members are key to the quality of our educational services, as well as our brand and reputation. Our ability to continue to attract faculty members, including teachers and mentors, with necessary experience and qualifications is a key driver in the success of our business. We seek to recruit qualified faculty members who are dedicated to teaching and are able to communicate with our students in an interactive online setting.

Additionally, given the interactive nature of our live streaming lessons, we tend to hire teachers and mentors with strong education background and good communication skills enabling them to engage and interact with students. The market for recruitment of faculty members in China is competitive. In order to recruit qualified full-time teachers and mentors, we must provide candidates with competitive compensation packages and offer attractive career development opportunities. Although we have not experienced major difficulties in recruiting or training qualified teachers and mentors in the past, we cannot guarantee we will be able to continue to recruit, train and retain a sufficient number of qualified faculty members in the future as we continue to expand our course offerings and business scale, which may have a material adverse effect on our business, financial condition and results of operations.

We may not be able to timely improve or expand our course and educational content offerings in a cost-effective manner to make them appealing to existing and prospective students, or at all.

We regularly and constantly update our existing courses and educational content and develop new courses and educational content to meet student’s demand and the latest market trends. The revisions, improvements and expansions of our existing course and content offerings and the development of new course and content offerings may not be accepted by existing or prospective students. Even if we are able to develop acceptable new course and educational content offerings, we may not be able to introduce them as quickly as students require or as quickly as our competitors introduce competing offerings. The process of performing detailed market research and recruiting qualified faculty for new course and educational content offerings could be costly and time-consuming. Furthermore, offering new courses or content or upgrading existing ones may require us to make significant investments in educational content development, increase sales and marketing efforts and reallocate resources from other uses, all of which may not be successful. If we are unsuccessful in pursuing course and educational content development and upgrading opportunities due to the financial constraints, failure to attract qualified faculty, or other factors, our ability to attract and retain students could be impaired and our financial results could suffer.

We believe that, even with the proliferation of internet and mobile devices in China, some of our target students may still be inclined to choose traditional face-to-face lessons offered by offline learning providers over online courses as they find the former more intimate and reliable. We cannot assure you that our live streaming course delivery format will continue to be attractive to our students in the future. If our live streaming course delivery model becomes less appealing to our students, our business and prospects may be affected. In addition, there is no assurance that our live streaming capacity will be able to support a growing number of students accessing our courses online without any service interruptions. Furthermore, we cannot assure that we will be able to address PRC regulatory and legislative developments relating to online streaming business. See “—We face regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs” and “—Our failure to obtain and maintain other approvals, licenses, permits or filings applicable to our business could have a material adverse impact on our business, financial conditions and results of operations.”

We are subject to the risks associated with third-party live streaming service providers.

Currently, while we rely on our proprietary live streaming platform to deliver online courses, we also use certain third-party vendors to provide live streaming services to support our online course delivery. Because the live streaming technologies and infrastructure are owned and managed by third parties, any problems with the reliability and performance of such technologies and infrastructure could result in unanticipated delays and unscheduled service interruption could further cause us to be unable to deliver our courses in a live streaming format, forcing us to resort to using prerecorded lectures. Our inability to deliver live streaming courses during service interruptions may damage the quality of our education service and student engagement and experience and negatively impact our reputation, financial condition and results of operations.

We do not maintain long-term arrangements with our live streaming service providers. The term of the service agreements we enter into with third-party live streaming service providers are generally one year. If we cannot renew such agreements upon their expirations or terminations on commercially reasonable terms, or at all, or if the live streaming service providers become unwilling or unable to provide us with live streaming services at any time for any reasons, our ability to deliver live streaming online courses will be severely impacted, and our students’ learning experience and our reputation will be harmed.

Failure to adequately and promptly respond to changes in the exams our students must take to pursue their desired degrees, diplomas or certifications could cause our education services to be less attractive to our students.

There have been continuous changes in the curriculum requirements associated with, and the format of, the exams our existing and prospective students must take to pursue their desired degrees, diplomas or certifications, the manner in which the exams are administered, as well as topics frequently tested in the exams. These changes require us to continually update and enhance our course offerings, our educational content and our teaching methods. Any inability to track and respond to these changes in a timely and cost-effective manner would make our education services less attractive to students, which may materially and adversely affect our reputation and ability to continue to attract students without a significant decrease in our tuition. In addition, as we further expand our course offerings, we cannot assure that we will be able to adapt our existing educational content and methods to new courses that we have limited experience in teaching.

We may face risks associated with the installment tuition payment plan we offer to our students.

In 2015, we launched an installment payment option enabling eligible students to obtain loans from accredited third-party credit providers in China to finance all or part of their tuition. The third-party credit providers are responsible for performing credit assessment, approving loan applications, providing the funds, and collecting delinquent loan payments. Under the loan agreement between the borrowing student and the lending credit provider, the borrowing student is obligated to repay the loan principal in installments over a period ranging from three to 18 months. Under the cooperation agreement between us and each credit provider, we are obligated to pay the full amount of interest payable under a loan, as financial service fees, to the credit provider. We do not provide any guarantees for the repayment of student loans in favor of the credit providers. In 2019, 2020 and 2021, our student loan coverage ratio was 70.4%, 54.9% and 24.8%, respectively. For the same periods, we made interest payments of RMB118.0 million, RMB83.3 million and RMB36.9 million (US$5.8 million), respectively, to the credit providers.

As part of our long-term sales and marketing strategy, we plan to continue to make the interest payments for our students under their loans and pay service fees to the credit providers, which may place significant strains on our financial resources. We may be subject to risks associated with an increase in interest rates to the extent that we continue to make interest payments for the loans taken by our students. If we cease to do so due to increases in interest rates or for other reasons, our course packages may become more costly for our students to purchase, which could in turn negatively impact our business, financial condition and reputation.

The availability of funding from our existing and potential credit providers depends on many factors, such as their liquidity and capital sufficiency, the legal and regulatory environment, the general economic conditions, default rates of our students on the loans, and, where applicable, the availability of lenders on the credit providers’ platforms. In addition, our credit providers may seek to acquire borrowers independently instead of through cooperation with us. We currently work with a limited number of credit providers and we cannot assure you that our credit providers will continue to cooperate with us on commercially favorable terms, or at all, or that existing or potential credit providers will be able to provide loans in a sufficient amount to meet our students’ borrowing needs. If any of these were to occur, our course packages may become less compelling to prospective students who wish to obtain student loans, and as a result our business and financial condition may be negatively affected.

Disruption to or failures of our IT infrastructure could reduce student satisfaction and could harm our operations.

The performance and reliability of our IT infrastructure is critical to our operations and reputation. We provide our course offerings and educational content to our students and faculty primarily through our applications and platforms built upon Genesis, our proprietary IT infrastructure. In addition, our employees, including our faculty and sales and marketing personnel, rely on our integrated IT infrastructure to carry out their marketing, sales, operation and teaching functions. As part of their educational experience, our students interact with their peers and our faculty via our platforms on a frequent basis. Accordingly, any errors, defects, disruptions or other performance problems with our IT infrastructure could damage our reputation, decrease student satisfaction and retention, adversely impact our ability to attract new students and expand our course offerings, and materially disrupt our operations. If any of these occur, our business operations, reputation and prospects could be harmed.

Our business depends on the continued success of our brand “Sunlands,” and if we fail to maintain and enhance recognition of our brand, we may face difficulty enrolling new students, and our reputation and operating results may be harmed.

We believe that market awareness of our brand “Sunlands” has contributed significantly to the success of our business. Maintaining and enhancing our brand are critical to our efforts to grow our student enrollments and gross billings. Failure to maintain and enhance our brand recognition could have a material and adverse effect on our business, operating results and financial condition. We have devoted significant resources to our brand promotion efforts in recent years, but we cannot assure you that these efforts will be successful. If we are unable to further enhance our brand recognition, or if we incur excessive marketing and promotion expenses, or if our brand image is negatively impacted by any negative publicity, our business and results of operations may be materially and adversely affected.

Students may decide not to continue taking our courses for a number of reasons, including a perceived lack of improvement in their academic performance or general dissatisfaction with our course and educational content offerings, which may adversely affect our business, financial condition, results of operations and reputation.

The success of our business depends on our ability to deliver high-quality learning experiences and help students achieve their learning objectives. We may not always be able to meet our students’ expectations in terms of academic performance due to a variety of reasons, many of which are outside of our control. We may face increased dropout rates and student dissatisfaction due to our students’ perceptions of our failure to help them achieve their anticipated academic goals, our students’ overall dissatisfaction with the quality of our course and educational content offerings and our faculty, as well as changing views of the value of the diplomas, degrees and qualifications they are pursuing through taking our courses. These factors may contribute to reduced student engagement and increased challenges in attracting and enrolling prospective students, all of which may adversely affect our prospects, business, financial condition, results of operations and reputation.

To the extent we rely on certain types of course offerings to generate revenues, we will subject to concentration risks, including risks resulting from changes in government policies.

Our reliance on certain types of course offerings may expose us to concentration risks. For example, we have historically relied on our Self-taught Higher Education Examination, or the STE course offerings, namely post-secondary courses designed for students pursuing associate diplomas or bachelor’s degrees by taking the STE exams, to generate revenues. In 2019, 2020 and 2021, our STE courses accounted for approximately 80.5%, 66.8% and 41.3% of our net revenues, respectively, and approximately 75.1%, 53.1% and 18.4% of our gross billings, respectively. During the same periods, our STE course offerings accounted for approximately 75.4%, 46.2% and 19.8%, respectively, of our new student enrollments.

If there are significant reductions in the perceived value of degrees or diplomas our students are pursuing through any of the courses we are offering, or if the PRC government releases substantial updates to the requirements or formats of the exams that our course offerings are designed for and we are unable to upgrade our course or educational content offerings to address such developments in a timely manner, the demand for and attractiveness of our course offerings may be adversely affected, which could have an adverse impact on our financial condition and results of operations.

If we fail to effectively identify, pursue and consummate strategic alliances or acquisitions, our ability to grow and to achieve profitability could be impacted.

We may from time to time engage in evaluations of, and discussions with, possible domestic and international acquisition or alliance candidates. We may not be able to identify suitable strategic alliances or acquisition opportunities, complete such transactions on commercially favorable terms, or successfully integrate business operations, infrastructure and management philosophies of acquired businesses and companies. There may be particular complexities, regulatory or otherwise, associated with our expansion into new markets, and our strategies may not succeed beyond our current markets. If we are unable to effectively address these challenges, our ability to execute acquisitions as a component of our long-term strategy will be impaired, which could have an adverse effect on our growth.

We face intense competition in our industry, which could divert student to our competitors, lead to pricing pressure and loss of market share, and significantly reduce our gross billings and net revenues.

China’s post-secondary and professional education market is intensely competitive. We compete with other online education service providers or traditional offline players, for student enrollments and engagement, high-quality academic and administrative faculty, and sales and marketing personnel, among other things. Some of our current and future competitors may have substantially greater name recognition and financial and other resources than we do, which may enable them to compete more effectively for potential students and decrease our market share. We also expect to face competition as a result of new entrants to the post-secondary and professional education market.

We may not be able to compete successfully against current or future competitors and may face competitive pressures that could adversely affect our business or results of operations. For example, increased competition may result in pricing pressure for us in terms of the tuition we are able to negotiate to receive from a student. In addition, online education is characterized by rapid changes in students’ technological requirements and expectations and evolving market standards, and our competitors may develop platforms or other technologies that are superior to the platform and technology we use. These differences may affect our ability to recruit and retain students, which may render our online course offerings less competitive. The increasingly competitive landscape may also result in longer and more complex sales cycles with a prospective student or a decrease in our market share, any of which could negatively affect our gross billings and net revenues and our ability to grow our business.

If our security measures are breached or fail and result in unauthorized disclosure of data by our employees or our third-party agents, we could lose existing students, fail to attract new students and be exposed to protracted and costly litigation.

Maintaining platform security is of critical importance to our students because the platform stores and transmits proprietary and confidential information, which may include sensitive personally identifiable information that may be subject to stringent legal and regulatory obligations. As an online education service provider, we face an increasing number of threats to our IT infrastructure, including unauthorized activity and access by our employees or third-party agents, system viruses, worms, malicious code and organized cyberattacks, which could breach our security and disrupt our business. For example, we have introduced data security and confidentiality protocols into the cooperation agreements we enter into with third-party sales agents with whom we share prospective students’ contact information, and we have made technical improvements in our IT infrastructure to prevent unauthorized access of confidential or sensitive personal information by our employees and third-party sales agents in the process of engaging prospective students. These measures, however, may not be as effective as we anticipate. In addition, there is no assurance that our third-party sales agents will comply with contractual and legal requirements with respect to data privacy when they collect data from our prospective students. If our security measures are breached or fail as a result of third-party action, employee error, malfeasance or otherwise, we could be subject to liability or our business could be interrupted, potentially over an extended period of time. Any or all of these issues could harm our reputation, adversely affect our ability to attract and enroll prospective students, cause prospective students not to enroll or stay enrolled, or subject us to third-party lawsuits, regulatory fines or other action or liability. Further, any reputational damage resulting from breach of our security measures could create distrust of our company by prospective students or investors. We may be required to expend significant additional resources to protect against the threat of these disruptions and security breaches or to alleviate problems caused by such disruptions or breaches.

Privacy concerns could limit our ability to collect and leverage our user data and disclosure of user data could adversely impact our business and reputation.

In the ordinary course of our business and in particular in connection with conducting sales and marketing activities with our existing and prospective students as well as the utilization of our AI-powered personalized study programs, we collect and utilize data supplied by our users. We currently face certain legal obligations regarding the manner in which we treat such information. Increased regulation of data utilization practices, including self-regulation or findings under existing laws that limit our ability to collect, transfer and use data, could have an adverse effect on our business. In addition, if we were to disclose data about our users in a manner that was objectionable to them, our business reputation could be adversely affected, and we could face potential legal claims and administrative penalties that could impact our operating results.

Internationally, we may become subject to additional and/or more stringent legal obligations concerning our treatment of customer and other personal information, such as laws regarding data localization and/or restrictions on data export. Failure to comply with these obligations could subject us to liability, and to the extent that we need to alter our business model or practices to adapt to these obligations, we could incur additional expenses.

We are subject to a variety of laws and other obligations regarding data protection, any failure to comply with applicable laws and obligations could have a material adverse effect on our business, financial condition and results of operations.

We are subject to various regulatory requirements relating to the security and privacy of data, including restrictions on the collection, storage and use of personal information and requirements to take steps to prevent personal data from being divulged, stolen, or tampered with. See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Internet Information Security and Privacy Protection.” Regulatory requirements regarding the protection of data are constantly evolving and can be subject to differing interpretations or significant change, making the extent of our responsibilities in that regard uncertain. For example, the Cybersecurity Law of the PRC became effective in June 2017, but there are great uncertainties as to the interpretation and application of the law. It is possible that those regulatory requirements may be interpreted and applied in a manner that is inconsistent with our practices. In addition, the Office of the Central Cyberspace Affairs Commission, the MIIT, the Ministry of Public Security, and the SAMR jointly issued an announcement on January 23, 2019 regarding carrying out special campaigns against mobile internet application programs collecting and using personal information in violation of applicable laws and regulations, which prohibits business operators from collecting personal information irrelevant to their services, or forcing users to give authorization in disguised manner. In addition, the PRC regulatory authorities have recently taken steps to strengthen the regulation on data protection and conducted several rounds of relevant inspections recently. We have been taking and will continue to take reasonable measures to comply with such announcement, provisions and inspection requirements.

On June 10, 2021, the Standing Committee of the National People’s Congress promulgated the PRC Data Security Law, effective on September 1, 2021. On August 17, 2021, the State Council promulgated the Regulations on Critical

Information Infrastructure Security Protection, which became effective on September 1, 2021. On August 20, 2021, the Standing Committee of the National People’s Congress promulgated the PRC Personal Information Protection Law, which came into effect on November 1, 2021. On November 11, 2021, the CAC published for public comment the Regulations on Cyber Data Security Management (Draft for Comments), or the Draft Cyber Data Security Regulations. The Draft Cyber Data Security Regulations stipulates that the data processing operators listed overseas shall conduct an annual data security assessment by themselves or a data security service institution, and submit the annual data security assessment report of the previous year to the competent cybersecurity authority before January 31 of each year. As of the date of this annual report, the Draft Cyber Data Security Regulations was not formally adopted and the final version and effective date of such regulations are subject to change with substantial uncertainty. In addition, on January 4, 2022, the CAC announced the adoption of the Cybersecurity Review Measures, which became effective on February 15, 2022. On the same date, the CAC published the Administrative Provisions on Internet Information Service Algorithm Recommendation on its website, which became effective on March 1, 2022.

These newly promulgated laws and regulations reflect PRC government further attempts to strengthen the legal protection for the national network security, data security, the security of critical information infrastructure and the security of personal information protection. See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations Relating to Internet Information Security and Privacy Protection”. However, as these announcements and provisions are relatively new, and the related implementation rules have yet been promulgated, it remains uncertain how these announcements and provisions will be implemented. We cannot assure you we can adapt our operations to it in a timely manner.

Any failure, or perceived failure by us to maintain the security of our students’ data and other confidential information or to comply with applicable privacy, data security and personal information protection laws, regulations, policies, contractual provisions, industry standards, and other requirements, may result in civil or regulatory liability, including governmental or data protection authority enforcement actions and investigations, fines, penalties, enforcement orders requiring us to cease operating in a certain way, or adverse publicity, and may require us to expend significant resources in responding to and defending allegations and claims. Furthermore, the PRC regulatory and enforcement regime with regard to privacy, data security and personal information protection is still evolving. PRC regulators have been increasingly focused on regulation in the areas of data security and data protection. We cannot assure you that relevant regulators will not interpret or implement these laws or regulations in ways that negatively affect us. It is possible that we may become subject to additional or new laws and regulations, which may result in additional expenses to us and subject us to potential liability and negative publicity. We expect that these areas will receive greater attention and focus from regulators, and attract continued or greater public scrutiny and attention going forward, which could increase our compliance costs and subject us to heightened risks and challenges associated with data security and protection. If we are unable to manage these risks, we could become subject to penalties, fines, suspension of business and revocation of required licenses, and our reputation and results of operations could be materially and adversely affected.

Tuition refunds or potential refund disputes may negatively affect our cash flow, financial condition, and reputation.

We offer different tuition refund options to our students depending on the time of enrollment and subject to certain conditions and restrictions in the service contract between us and each of our students. Generally, a student is offered a full, unconditional refund within 24 hours upon enrollment. If the student makes a refund request after taking at least one live streaming course lasting 30 minutes by reason of any material academic issue of our courses within certain refund period, we offer a refund excluding the registration fees and the fees of delivered courses upon our confirmation. In addition, we offer students a refund for the undelivered courses excluding the registration fees. Prior to June 2019, such refund was provided only within seven days upon enrollment while starting from June 2019, we offer such refund during the entire service period. When calculating gross billings for a specific period, we deduct the total amount of refunds from the total amount of cash received for the sale of course packages for such period. See “Item 4. Information on the Company—4.B. Business Overview—Our Tuition and Fees.”

In 2019, 2020 and 2021, we had made RMB 345.9 million, RMB335.5 million and RMB282.5 million (US$44.4 million) of refund payments, respectively, most of which were made pursuant to our tuition refund policy, see “Item 4. Information on the Company—4.B. Business Overview—Business—Our Tuition and Fees.” The number of refund requests and the amount of refunds could be affected by a number of factors. These factors include, without limitation to, student dissatisfaction with our teaching quality and our course and educational content offerings, privacy concerns relating to our online platforms, negative publicity regarding us or online education in general, the terms and scope of our refund policy, and any change or development in PRC laws and regulations with respect to fees and tuitions charged by online education providers like us. See “—We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry, including the Law

for Promoting Private Education and its Implementing Rules.” As part of our efforts to enhance user experience, from June 2019, we amended certain terms of our refund policy to facilitate a more flexible and smoother refund process. Any refund payments that we may be required to make to our students, as well as the expenses we could incur for processing refunds and resolving refund disputes, could be substantial and could adversely affect our gross billings, net revenues, liquidity and financial condition. A high volume of refunds and refund disputes may also generate negative publicity that could harm our reputation. We have experienced in the past, and may experience in the future, negative publicity in relation to refund disputes between us and our students, which may significantly harm our brand name and divert our attention from operating our business.

We cannot assure you that we will not be subject to liability claims or legal or regulatory liability for any inappropriate or illegal content, which could subject us to liabilities and cause damages to our reputation.

Although we implement various monitoring procedures to identify and remove inappropriate or illegal content, we cannot assure you that there will be no inappropriate or illegal content included in our content offerings including content generated and uploaded to our online platforms by our users. For example, we have been historically penalized for inaccurate advertising. We may face civil, administrative or criminal liability or legal or regulatory sanctions, such as requiring us to restrict or discontinue our content, products or services, if an individual or corporate, governmental or other entity believes that any of the content offerings violates any laws, regulations or governmental policies or infringes upon its legal rights. Even if such a claim were not successful, defending such a claim may cause us to incur substantial costs. Moreover, any accusation of inappropriate or illegal content in our content offerings could lead to significant negative publicity, which could harm our reputation, business, financial condition and results of operations.

Our success depends on the continuing efforts of our senior management team and other key employees.

We depend on the continued contributions of our senior management and other key employees, including, in particular, Mr. Jianhong Yin, also known as Peng Ou, our founder and the chairman of our Board of Directors, and Mr. Tongbo Liu, our director and Chief Executive Officer. The loss of the services of any of our senior management or other key employees could harm our business. Competition for qualified talents in China is intense. If one or more of our senior management or other key employees are unable or unwilling to continue in their present positions, we may not be able to find replacements in a timely manner, or at all, and our business may be disrupted. Moreover, if any member of our senior management team or any of our other key personnel joins a competitor or forms or invests in a competing business, we may lose student enrollments, qualified teaching faculty members and other key sales and marketing personnel to our competitors. Our future success is also dependent on our ability to attract a significant number of qualified employees and retain existing key employees. If we are unable to do so, our business and growth may be materially and adversely affected. Our need to significantly increase the number of our qualified employees and retain key employees may cause us to materially increase compensation-related costs, including share-based compensation.

If we cannot maintain our corporate culture as we grow, we could lose the innovation, collaboration and focus that contribute to our business.

We believe that a critical component of our success is our corporate culture, which fosters innovations and has roots in a deep understanding of our students and the evolving education industry in China. As we continue to expand and grow our business, we may find it difficult to maintain these valuable aspects of our corporate culture. Any failure to preserve our culture could undermine our reputation in the marketplace and negatively impact our ability to attract and retain employees and students, which would in turn jeopardize our future success.

We may from time to time be subject to infringement claims relating to intellectual properties of third parties.

We cannot assure you that our course offerings and educational contents and our IT technologies and platforms do not or will not infringe upon copyrights or other intellectual property rights held by third parties. We may encounter disputes from time to time over rights and obligations concerning intellectual properties, and we may not prevail in those disputes.

We have adopted policies and procedures to prohibit our students and employees from infringing upon third-party copyright or intellectual property rights. However, we cannot ensure that they will not, against our policies, use third-party copyrighted materials or intellectual property without proper authorization in our classes or via any medium through which we provide our services. We may incur liability for unauthorized duplication or distribution of materials posted on our websites or used in our classes. We have been involved in claims against us alleging our infringement of third-party intellectual property rights and we may be subject to such claims in the future. We have not entered into any licensing arrangements with, or otherwise obtained any consent from, the government agencies administering the STE exams for using certain exam questions in our quiz banks. Although we have never been subject to any legal or administrative penalties or proceedings relating to our use of these sample questions, we cannot assure you that we will not be subject to infringement claims associated with our use of real STE questions in the future. Any such intellectual property infringement claim could result in costly litigation and divert our management attention and resources, which in turn could negatively affect our business, financial condition and prospect.

If we fail to protect our intellectual property rights, our brand and business may suffer.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. Although we seek to obtain copyright or patent protection for our intellectual property when applicable, it is possible that we may not be able to do so successfully or that the copyright or patent we have obtained may not be sufficient to protect all of our intellectual property rights. In particular, we rely, to the great extent, upon our educational content developed in-house, including course syllabi and outlines, quiz banks, teaching notes, and learning outcomes trees, to provide high-quality online education services. Despite our efforts to protect our proprietary education contents and other intellectual property rights, unauthorized parties may attempt to copy or duplicate our intellectual property or otherwise use our intellectual properties without obtaining our consent. Monitoring unauthorized use of our intellectual property is difficult and costly, and we cannot be certain that the steps we have taken will effectively prevent misappropriation of our intellectual properties. If we are not successful in protecting our intellectual property rights, our business and results of operations may be adversely affected.

Our students, employees and third-party vendors may engage in intentional or negligent misconduct or other improper activities or misuse our platform, which could harm our brand and reputation.

We are exposed to the risk of fraud or other misconducts committed by our students, employees and vendors, including certain third-party sales and marketing agencies. For example, in some instances, our students and our faculty members may post to our platform articles or other third-party content for use in class discussions. The PRC laws governing the fair use of these third-party materials are imprecise and adjudicated on a case-by-case basis, which makes it challenging for us to adopt and implement policies governing these practices. We could, as a result, incur liability to third parties for the unauthorized duplication, distribution or other use of these materials. Any such claims could subject us to costly litigation and impose a significant strain on our financial resources and attention of management personnel regardless of whether the claims have merit. We may be required to alter or cease our uses of such materials, which may include changing or removing content from courses or altering the functionality of our platform, or to pay monetary damages. Fraud or other misconducts by our students, employees or third parties may also involve engaging in unauthorized misrepresentation to our potential students and misappropriating third-party intellectual property and other propitiatory rights during marketing activities, misusing sensitive personal information of our students, and engaging in bribery or other unlawful payments, any of which could result in customer complaints, regulatory and legal liabilities, as well as serious harm to our brand and reputation.

Our courses undergo multiple rounds of internal review before being broadly released. While we proactively monitor our live courses and other content and communications to ensure that we are able to identify content that may be deemed inappropriate or in violation of laws, regulations and government policies, since we have limited control over the real-time and offline behavior of our users and employees, to the extent any improper behavior is associated with our content and services, our ability to protect our reputation may be limited. If any of our users and employees suffer or allege to have suffered harm following contact initiated through our services, we may face civil lawsuits or other liabilities. In response to allegations of illegal or inappropriate activities, PRC government authorities may intervene and hold us liable for non-compliance with PRC laws and regulations concerning the dissemination of information on the internet and subject us to administrative penalties or other sanctions, such as requiring us to restrict or discontinue our content or services. As a result, our business may suffer and our reputation, business, financial condition and results of operations may be materially and adversely affected.

We may be the subject of detrimental conduct by third parties such as our competitors, including complaints to regulatory agencies and the public dissemination of malicious assessments of our business, which could have a negative impact on our reputation and cause us to lose market share, students and revenues, and adversely affect the price of the ADSs.

We have been, and in the future may be, the target of anti-competitive, harassing or other detrimental conduct by third parties including our competitors. Such conduct may include complaints, anonymous or otherwise, to regulatory agencies regarding our operations, accounting, business relationships, business prospects and business ethics. Additionally, allegations, directly or indirectly against us, may be posted online by anyone, whether or not related to us, on an anonymous basis. We may be subject to government or regulatory investigation as a result of such third-party conduct and may be required to expend significant time and incur substantial costs to address such third-party conduct, and there is no assurance that we will be able to conclusively refute each of the allegations within a reasonable period of time, or at all. Our reputation may also be materially negatively affected as a result of the public dissemination of anonymous allegations or malicious statements about our business, which in turn may cause us to lose students and revenues, and adversely affect the price of the ADSs.

Our user metrics and other estimates are subject to inaccuracy in measuring our operating performance, which may harm our reputation.

We continually review number of students, new student enrollments, gross billings per new student enrollment, and other operating metrics to evaluate growth trends, measure our performance and make strategic decisions. These metrics are calculated using internal data, have not been validated by an independent third party and may not be indicative of our future operating performance. While these numbers are based on what we believe to be reasonable estimates for the applicable period of measurement, there are inherent challenges in measuring how our website and mobile application are used across a large student base. For example, we may not be able to identify individual students who have multiple accounts from multiple students who share one account on our website or mobile application. In addition, we collect student reviews to measure student satisfaction rate and other student engagement metrics, but these reviews may not be representative of our entire student population. Errors or inaccuracies in our metrics or data could result in incorrect business decisions and inefficiencies. For instance, if a significant understatement or overstatement of student satisfaction or marketing spending were to occur, we might expend resources to implement unnecessary business measures or fail to take required actions to remedy an unfavorable trend. If investors do not perceive our operating metrics to accurately represent our operating performance, or if we discover material inaccuracies in our operating metrics, our reputation may be harmed.

If we fail to implement and maintain an effective system of internal controls, we may be unable to accurately or timely report our results of operations or prevent fraud, and investor confidence and the market price of the ADSs may be materially and adversely affected.

We are a public company in the United States subject to the Sarbanes-Oxley Act of 2002. Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, requires that we include a report from management on our internal control over financial reporting in our annual report on Form 20-F beginning with our annual report for the fiscal year ended December 31, 2019. In addition, once we cease to be an “emerging growth company” as such term is defined in the JOBS Act, our independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. Our management may conclude that our internal control over financial reporting is not effective. Moreover, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, as we are a public company, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future and we may be unable to timely complete our evaluation testing and any required remediation.

During the course of documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404, we may identify weaknesses and deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404. Generally speaking, if we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could in turn limit our access to capital markets, harm our results of operations and lead to a decline in the trading price of the ADSs. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse

of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions.

We have incurred increased costs as a result of being a public company, particularly after we cease to qualify as an “emerging growth company.”

We are a public company and expect to continue to incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the U.S. Securities and Exchange Commission, or the SEC, and the New York Stock Exchange, impose various requirements on the corporate governance practices of public companies. As a company with less than US$1.07 billion in revenues for our last fiscal year, we qualify as an “emerging growth company” pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, in the assessment of the emerging growth company’s internal control over financial reporting. The JOBS Act also permits an emerging growth company to delay adopting new or revised accounting standards until such time as those standards apply to private companies. However, we have elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted for public companies. This decision to opt out of the extended transition period under the JOBS Act is irrevocable.

We expect these rules and regulations to increase our legal and financial compliance costs and to make some corporate activities more time-consuming and costly. After we are no longer an “emerging growth company,” we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 and the other rules and regulations of the SEC. In addition, we will incur additional costs associated with our public company reporting requirements. It may also be more difficult for us to find qualified persons to serve on our Board of Directors or as executive officers. We are currently evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate with any degree of certainty the amount of additional costs we may incur or the timing of such costs.

We have granted, and may continue to grant, share incentives, which may result in increased share based compensation expenses.

We adopted an equity incentive plan in October 2017, or the 2017 Plan, for the purpose of granting share based compensation awards to employees, officers, directors and consultants to incentivize their performance and promote the success of our business.

We account for compensation costs for all share-based awards using a fair-value based method and recognize expenses in our consolidated statements of operations in accordance with U.S. GAAP. Under the 2017 Plan, we are authorized to grant options, restricted stock units and other types of awards the administrator of the 2017 Plan decides. Under the 2017 Plan, the maximum aggregate number of shares which may be issued pursuant to all awards is 829,349 shares. As of the date of this annual report, options to purchase a total of 31,546 ordinary shares were outstanding under the 2017 Plan. All of the ordinary shares reserved and issuable upon the exercise of options granted pursuant to the 2017 Plan shall, upon issuance of such ordinary shares, be designated as Class C ordinary shares. We believe the granting of share-based awards is of significant importance to our ability to attract and retain key personnel and employees, and we will continue to grant share-based awards in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations.

If we fail to make adequate contributions to various employee benefits plans as required by PRC regulations, we may be subject to penalties.

Companies operating in China are required to participate in various government-sponsored employee benefit plans, including certain social insurance, housing funds and other welfare-oriented payment obligations, and contribute to the plans in amounts equal to certain percentages of salaries, including bonuses and allowances, of employees up to a maximum amount specified by the local government from time to time at locations where our employees are based. The requirement of employee benefit plans has not been implemented consistently by the local governments in China given the different levels of economic development in different locations. If we fail to make adequate contributions to various employee benefit plans and comply with applicable PRC labor-related laws, we may be subject to late payment penalties, and we could be required to make up the contributions for these plans as well as to pay late fees and fines. If we are subject to late fees or fines in relation to the underpaid employee benefits, our financial condition and results of operations may be adversely affected. In addition, to the extent that we can make a reasonable estimate of the liability arising from our failure in making full contributions to various employee benefit plans, we will record a related contingent liability. However, the amount of our estimates may be

inaccurate, in which case our financial condition and cash flow may be adversely affected if we were to pay late fees or fines in relation to the underpaid employee benefits.

Increases in labor costs in the PRC may adversely affect our business and results of operations.

The currently effective PRC Labor Contract Law was first adopted on June 29, 2007 and later amended on December 28, 2012. The PRC Labor Contract Law has reinforced the protection of employees who, under the PRC Labor Contract Law, have the right, among others, to have written employment contracts, to enter into employment contracts with no fixed term under certain circumstances, to receive overtime wages and to terminate or alter terms in labor contracts. Furthermore, the PRC Labor Contract Law sets forth additional restrictions and increases the costs involved with dismissing employees. To the extent that we need to significantly reduce our workforce, the PRC Labor Contract Law could adversely affect our ability to do so in a timely and cost-effective manner, and our results of operations could be adversely affected. In addition, for employees whose employment contracts include noncompetition terms, the PRC Labor Contract Law requires us to pay monthly compensation after such employment is terminated, which will increase our operating expenses.

In addition, we are required by PRC laws and regulations to make social insurance registration and open housing fund account with relevant governmental authorities and pay various statutory employee benefits, including pensions, housing fund, medical insurance, work-related injury insurance, unemployment insurance and maternity insurance to designated government agencies for the benefit of our employees. The relevant government agencies may examine whether an employer has made adequate payments of the requisite statutory employee benefits, and those employers who fail to make adequate payments may be subject to late payment fees, fines and/or other penalties. If we fail to make adequate social insurance and housing fund contributions, we may be subject to fines and legal sanctions, and our business, financial condition and results of operations may be adversely affected. We expect that our labor costs, including wages and employee benefits, will continue to increase. Unless we are able to pass on these increased labor costs to our customers by increasing the prices of our products and services, our financial conditions and results of operations would be materially and adversely affected.

We lease real properties from third parties primarily for our office use in China, and the lease agreements for most of these leased properties have not been registered with the PRC governmental authorities as required by PRC law. Although the failure to do so does not in itself invalidate the leases, we may be ordered by the PRC government authorities to rectify such noncompliance and, if such noncompliance were not rectified within a given period of time, we may be subject to fines imposed by PRC government authorities ranging from RMB1,000 and RMB10,000 for our lease agreements that have not been registered with the relevant PRC governmental authorities.

As of the date of this annual report, we are not aware of any regulatory or governmental actions, claims or investigations being contemplated or any challenges by third parties to our use of our leased properties the lease agreements of which have not been registered with the government authorities. However, we cannot assure you that the government authorities will not impose fines on us due to our failure to register any of our lease agreements, which may negatively impact our financial condition.

We lease real properties from third parties in China for marketing and providing offline consultation related to our online services for potential students or existing students. Some of the ownership certificates or other similar proof of certain leased properties have not been provided to us by the relevant lessors. Therefore, we cannot assure you that such lessors are entitled to lease the relevant real properties to us. If the lessors are not entitled to lease the real properties to us and the owners of such real properties decline to ratify the lease agreements between us and the respective lessors, we may not be able to enforce our rights to lease such properties under the respective lease agreements against the owners. As of the date of this annual report, we are not aware of any claim or challenge brought by any third parties concerning the use of our leased properties without obtaining proper ownership proof. If our lease agreements are claimed as null and void by third parties who are the real owners of such leased real properties, we could be required to vacate the properties, in the event of which we could only initiate the claim against the lessors under relevant lease agreements for indemnities for their breach of the relevant leasing agreements. We cannot assure you that suitable alternative locations are readily available on commercially reasonable terms, or at all, and if we are unable to relocate our operations in a timely manner, our operations may be interrupted.

Our operations depend on the performance of the internet infrastructure and telecommunications networks in China.

The successful operation of our business depends on the performance of the internet infrastructure and telecommunications networks in China. Almost all access to the internet is maintained through state-owned telecommunications operators under the administrative control and regulatory supervision of the MIIT. Moreover, we have entered into contracts with various subsidiaries of a limited number of telecommunications service providers at provincial level and rely on them to provide us with data communications capacity through local telecommunications lines. We have limited access to alternative networks or services in the event of disruptions, failures or other problems with China’s internet infrastructure or the telecommunications networks provided by telecommunications service providers. Our platform regularly serves a large number of users and advertisers. With the expansion of our business, we may be required to upgrade our technology and infrastructure to keep up with the increasing traffic on our platform. However, we have no control over the costs of the services provided by telecommunications service providers. If the prices we pay for telecommunications and internet services rise significantly, our results of operations may be materially and adversely affected. If internet access fees or other charges to internet users increase, our user traffic may decline and our business may be harmed.

We and certain of our directors and officers have been named as defendants in a shareholder class action lawsuit, which could have a material adverse impact on our business, financial condition, results of operation, cash flows and reputation.

We will have to defend against the class action lawsuit described in “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings,” including any appeals should our initial defense be unsuccessful. We are currently unable to estimate the potential loss, if any, associated with the resolution of such lawsuit. We cannot guarantee that we will not be a target for lawsuits in the future, including putative class action lawsuits brought by shareholders. There can be no assurance that we will be able to prevail in our defense or reverse any unfavorable judgment on appeal, and we may decide to settle lawsuits on unfavorable terms. Any adverse outcome of these cases, including any plaintiffs’ appeal of the judgment in these cases, could result in payments of substantial monetary damages or fines, or changes to our business practices, and thus have a material adverse effect on our business, financial condition, results of operation, cash flows and reputation. In addition, there can be no assurance that our insurance carriers will cover all or part of the defense costs, or any liabilities that may arise from these matters. The litigation process may utilize a significant portion of our cash resources and divert management’s attention from the day-to-day operations of our company, all of which could harm our business. We also may be subject to claims for indemnification related to these matters, and we cannot predict the impact that indemnification claims may have on our business or financial results.

Insurance companies in China currently do not offer as extensive an array of insurance products as insurance companies in more developed economies. Currently, we do not have any business liability or disruption insurance to cover our operations. We have determined that the costs of insuring for these risks and the difficulties associated with acquiring such insurance on commercially reasonable terms make it impractical for us to have such insurance. Any uninsured business disruptions may result in our incurring substantial costs and the diversion of resources, which could have an adverse effect on our results of operations and financial condition.

We face risks related to natural disasters, extreme weather conditions, health epidemics and other catastrophic incidents, which could significantly disrupt our operations.

China has in the past experienced significant natural disasters, including earthquakes, extreme weather conditions, as well as health scares related to epidemic diseases, and any similar event could materially impact our business in the future. If a disaster or other disruption were to occur in the future that affects the regions where we operate our business, our operations could be materially and adversely affected due to loss of personnel and damages to property. Even if we are not directly affected, such a disaster or disruption could affect the operations or financial condition of our ecosystem participants, which could harm our results of operations.

In addition, accidents, disasters and public health challenges in China and globally could impact our business and results of operations. These types of events could negatively impact user activity and our local operations, if any, in the affected regions, or, depending upon the severity, across China or globally, which could adversely impact our business and results of operations.

In early January of 2020, the outbreak of the novel coronavirus, commonly referred to as “COVID-19”, first found in mainland China, then in Asia and eventually throughout the world, has significantly affected business and other activities within China. China has experienced widespread economic disruption owing to the outbreak of the COVID-19 coronavirus

and stringent government measures to contain it, including nationwide restricting access to provinces and cities, reducing agglomeration activities, and postponing non-essential business activates. In the second half of 2021, the COVID-19 coronavirus resurged in China due to Omicron and Delta variants. The outbreak of COVID-19, had caused temporary interruptions to the learning activities of our students and operations of our business partners and negatively affected certain aspects of our business operations in 2020. For example, the Self-taught Higher Education Examination, or the STE, a state-administered exam in China for learners pursuing associate diplomas or bachelor’s degrees, was postponed by the Ministry of Education of the PRC as a result of the COVID-19 pandemic, resulting in fluctuations in enrollments for our STE courses which have historically represented a significant portion of our net revenues, gross billings and new student enrollments of our online course offerings. Our business activities were not significantly affected or interrupted in 2021. We have taken precautionary measures intended to minimize the risks of COVID-19 to our students, employees, teachers, mentors and business partners, including temporarily requiring our employees to work remotely or canceling or postponing sponsored offline events and activities, which could compromise our efficiency and productivity during such periods, require us to incur additional costs, slow down our branding and marketing efforts, and result in fluctuations in our results of operations. While the foregoing restrictions and measures have been eased and our business operations have been recovered, our results of operations may be adversely affected to the extent that COVID-19 continues to affect the Chinese economy in general. Additionally, as COVID-19 continues to evolve into a worldwide health crisis that could adversely affect the economies and financial markets of countries other than China, it may potentially result in an economic downturn that could affect demand for our users, business partners and services and therefore materially adversely affect our business, financial condition and results of operations. Furthermore, to the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this section entitled “Item 3. Key Information—3.D. Risk Factors,” such as those relating to our ability to improve or expand our product and service offerings, and to retain existing or attract new advertising customers, among other things.

There are substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations, and rules relating to the agreements that establish the VIE structure for our operations in China, including potential future actions by the PRC government, which could affect the enforceability of our contractual arrangements with the VIEs and, consequently, significantly affect our financial condition and results of operations. If the PRC government finds such agreements non-compliant with relevant PRC laws, regulations, and rules, or if these laws, regulations, and rules or the interpretation thereof change in the future, we could be subject to severe penalties or be forced to relinquish our interests in the VIEs.

Foreign investment in the value-added telecommunication services industry in China is extensively regulated and subject to numerous restrictions. Pursuant to the list of special management measures for the market entry of foreign investment, or the Negative List, published by the National Development and Reform Commission and the Ministry of Commerce on December 27, 2021 and effective on January 1, 2022, with a few exceptions, foreign investors are not allowed to own more than 50% of the equity interests in a value-added telecommunication service provider.

We are a Cayman Islands company and our wholly-owned PRC subsidiaries are currently considered foreign-invested enterprise. Accordingly, our PRC subsidiaries are not eligible to provide value-added telecommunication services in China. To ensure strict compliance with the PRC laws and regulations, we conduct such business activities through our consolidated variable interest entities, or the VIEs, and their respective subsidiaries. Our wholly owned subsidiaries in China have entered into a series of contractual arrangements with the VIEs, their respective shareholders and their respective subsidiaries, which enable us to (i) exercise effective control over the VIEs, (ii) receive substantially all of the economic benefits of the VIEs, and (iii) have an exclusive option to purchase all or part of the equity interests and assets in the VIEs when and to the extent permitted by PRC law. As a result of these contractual arrangements, we have control over and are the primary beneficiary of the VIEs and hence consolidate its financial results as the VIEs under U.S. GAAP. See “Item 4. Information of the Company—4.C. Organizational Structure” for further details.

It is uncertain whether any new PRC laws, rules or regulations relating to variable interest entity structures will be adopted or if adopted, what they would provide. For example, the Amended Implementing Rules provide that, among other things, any entities or individuals shall not control any schools providing compulsory education or any non-profit schools providing pre-school education through merger, acquisition or contractual arrangements. As of the date of this annual report, two of our schools are privately run non-enterprise institution and have not made the election to be registered as a for-profit or non-profit school. Since neither of such two schools provide compulsory education or pre-school education, the validity and enforceability of our contractual arrangements are not challenged yet. However, since the laws and regulations are still evolving and new PRC laws, regulations, rules and interpretations may be introduced to impose additional requirements, posing additional challenges to our corporate structure and contractual arrangements, there are substantial uncertainties

regarding whether we could comply with new laws, regulations, rules and interpretations in a timely manner, or at all. Any failure to comply with such regulatory requirements may challenge the validity and enforceability of our contractual arrangements.

If the PRC government finds that our contractual arrangements do not comply with its restrictions on foreign investment in the value-added telecommunication services, or if the PRC government otherwise finds that we, the VIEs, or any of its subsidiaries are in violation of PRC laws or regulations or lack the necessary permits or licenses to operate our business, the relevant PRC regulatory authorities, including the MIIT and SAMR, would have broad discretion in dealing with such violations or failures, including, without limitation:

Any of these actions could cause significant disruptions to our business operations and severely damage our reputation, which would in turn materially and adversely affect our business, financial condition and results of operations. In addition, new PRC laws, regulations, and rules may be introduced to impose additional requirements, posing additional challenges to our corporate structure and contractual arrangements. If any of these occurrences results in our inability to direct the activities of the VIEs or our failure to receive the economic benefits from the VIEs and/or our inability to claim our contractual control rights over the assets of the VIEs that conduct our operations in China, we may not be able to consolidate the entity in our consolidated financial statements in accordance with U.S. GAAP which could materially and adversely affect our financial condition and results of operations and cause our ADSs to significantly decline in value or become worthless.

Any failure by the VIEs or their shareholders to perform their obligations under our contractual arrangements with them would have a material adverse effect on our business.

Since PRC laws prohibit or restrict foreign equity ownership in certain kinds of business in China, we have relied and expect to continue to rely on the contractual arrangements with the VIEs and their shareholders to operate our business in China.

However, these contractual arrangements may not be as effective as direct ownership in providing us with control over our affiliated entities, including the VIEs and their subsidiaries. Any of our affiliated entities and their shareholders could breach their contractual arrangements with us by, among other things, failing to conduct their operations in an acceptable manner or taking other actions that are detrimental to our interests. In the event that the shareholders of the VIEs breach the terms of these contractual arrangements and voluntarily liquidate the VIEs, or the VIEs declare bankruptcy and all or part of their assets become subject to liens or rights of third-party creditors, or are otherwise disposed of without our consent, we may be unable to conduct some or all of our business operations or otherwise benefit from the assets held by our affiliated entities, which could have a material adverse effect on our business, financial condition and results of operations.

Most of the nominee shareholders of the VIEs are also beneficial owners of our company. The enforceability of the contractual agreements between us, the VIEs and their shareholders depends to a large extent upon whether the VIEs and their shareholders will fulfill these contractual agreements. Their interests in enforcing these contractual agreements may not align with our interests or the interests of our shareholders. If their interest diverges from that of our company and other shareholders, it may potentially increase the risk that they could seek to act contrary to these contractual arrangements. If the VIEs or their shareholders fail to perform their respective obligations under the contractual arrangements, we may have to incur substantial costs and expend additional resources to enforce such arrangements. We may also have to rely on legal remedies under PRC law, including seeking specific performance or injunctive relief, and contractual remedies, which we

cannot assure you will be sufficient or effective under PRC law. Our contractual arrangements are governed by PRC law and provide for the resolution of disputes through litigation in China. Accordingly, these agreements would be interpreted in accordance with PRC law and any disputes would be resolved in accordance with PRC legal procedures. The legal system in the PRC is not as developed as in some other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements. Meanwhile, there are very few precedents and little formal guidance as to how contractual arrangements in the context of a consolidated variable interest entity should be interpreted or enforced under PRC law.

There remain significant uncertainties regarding the ultimate outcome of such adjudication should legal action become necessary. In the event that we are unable to enforce these contractual arrangements, or if we suffer significant delay or other obstacles in the process of enforcing these contractual arrangements, we may not be able to exert effective control over our affiliated entities, and our ability to conduct our business may be negatively affected.

We rely on contractual arrangements with the VIEs and their respective shareholders for a significant portion of our business operations which may not be as effective as direct ownership in providing operational control.

We have relied and expect to continue to rely on contractual arrangements with the VIEs, their respective shareholders and their respective subsidiaries to operate our online education services business in China. These contractual arrangements may not be as effective as direct ownership in providing us with control over the VIEs. For example, the VIEs and their respective shareholders could breach their contractual arrangements with us by, among other things, failing to conduct their operations in an acceptable manner or taking other actions that are detrimental to our interests. The revenues contributed by the VIEs and their respective subsidiaries constituted 93.4%, 47.3% and 21.4% of our total net revenues in 2019, 2020 and 2021, respectively.

If we had direct ownership of the VIEs, we would be able to exercise our rights as a shareholder to effect changes in the board of directors of the VIEs, which in turn could implement changes, subject to any applicable fiduciary obligations, at the management and operational level. However, under the current contractual arrangements, we rely on the performance by the VIEs and their respective shareholders of their obligations under the contracts to exercise control over the VIEs. The shareholders of our consolidated VIEs may not act in the best interests of our company or may not perform their obligations under these contracts. Such risks exist throughout the period in which we intend to operate certain portions of our business through the contractual arrangements with the VIEs. If any disputes relating to these contracts remain unresolved, we will have to enforce our rights under these contracts through the operations of PRC law and arbitration, litigation and other legal proceedings and therefore will be subject to uncertainties in the PRC legal system. Therefore, our contractual arrangements with the VIEs may not be as effective in ensuring our control over the relevant portion of our business operations as direct ownership would be.

Any failure by the VIEs or their respective shareholders to perform their obligations under our contractual arrangements with them would have a material and adverse effect on our business.

If the VIEs or their respective shareholders fail to perform their respective obligations under the contractual arrangements, we may have to incur substantial costs and expend additional resources to enforce such arrangements. We may also have to rely on legal remedies under PRC law, including seeking specific performance or injunctive relief, and claiming damages, which we cannot assure will be effective under PRC law. For example, if the shareholders of the VIEs refuse to transfer their equity interest in the VIEs to us or our designee if we exercise the purchase option pursuant to these contractual arrangements, or if they otherwise act in bad faith toward us, then we may have to take legal actions to compel them to perform their contractual obligations. In addition, if any third parties claim any interest in such shareholders’ equity interests in the VIEs, our ability to exercise shareholders’ rights or foreclose the share pledge according to the contractual arrangements may be impaired. If these or other disputes between the shareholders of the VIEs and third parties were to impair our control over the VIEs, our ability to consolidate the financial results of the VIEs would be affected, which would in turn result in a material adverse effect on our business, operations and financial condition.

Our contractual arrangements are governed by PRC laws. Accordingly, these contracts would be interpreted in accordance with PRC laws, and any disputes would be resolved in accordance with PRC legal procedures.

The legal system in the PRC is not as developed as in some other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements. Meanwhile, there are very few precedents and little formal guidance as to how contractual arrangements in the context of a VIE should be interpreted or enforced under PRC laws. There remain significant uncertainties regarding the ultimate outcome of such arbitration should legal action become necessary. In addition, under PRC law, rulings by arbitrators are final, parties cannot appeal the arbitration results in courts, and if the losing parties fail to carry out the arbitration awards within a prescribed time limit, the prevailing parties may only enforce the arbitration awards in PRC courts, which would require additional expenses and delay. In the event we are unable to enforce these contractual arrangements, or if we suffer significant delays or other obstacles in the process of enforcing these contractual arrangements, we may not be able to exert effective control over the VIEs, and our ability to conduct our business may be negatively affected.

The shareholders of the VIEs may have actual or potential conflicts of interest with us, which may materially and adversely affect our business and financial condition.

The shareholders of the VIEs may have actual or potential conflicts of interest with us. These shareholders may refuse to sign or breach, or cause the VIEs to breach, or refuse to renew, the existing contractual arrangements we have with them and the VIEs, which would have a material and adverse effect on our ability to effectively control the VIEs and receive economic benefits from it. For example, the shareholders may be able to cause our agreements with the VIEs to be performed in a manner adverse to us by, among other things, failing to remit payments due under the contractual arrangements to us on a timely basis. We cannot assure you that when conflicts of interest arise any or all of these shareholders will act in the best interests of our company or such conflicts will be resolved in our favor. Currently, we do not have any arrangements to address potential conflicts of interest between these shareholders and our company. If we cannot resolve any conflict of interest or dispute between us and these shareholders, we would have to rely on legal proceedings, which could result in disruption of our business and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

Contractual arrangements in relation to the VIEs may be subject to scrutiny by the PRC tax authorities and they may determine that we or the VIEs owe additional taxes, which could negatively affect our financial condition and the value of your investment.

Under applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities within ten years after the taxable year when the transactions are conducted. We could face material and adverse tax consequences if the PRC tax authorities determine that the VIE contractual arrangements were not entered into on an arm’s-length basis in such a way as to result in an impermissible reduction in taxes under applicable PRC laws, rules and regulations, and adjust the income of the VIEs in the form of a transfer pricing adjustment. A transfer pricing adjustment could, among other things, result in a reduction of expense deductions recorded by the VIEs for PRC tax purposes, which could in turn increase its tax liabilities without reducing our PRC subsidiary’s tax expenses. In addition, the PRC tax authorities may impose late payment fees and other penalties on the VIEs for the adjusted but unpaid taxes according to the applicable regulations. Our financial position could be materially and adversely affected if the VIEs’ tax liabilities increase or if it is required to pay late payment fees and other penalties.

We may lose the ability to use, or otherwise benefit from, the licenses, approvals and assets held by the VIEs, which could severely disrupt our business, render us unable to conduct some or all of our business operations and constrain our growth.

As part of our contractual arrangements with the VIEs, the VIEs hold certain assets, licenses and permits that are material to our business operations, such as the ICP License and the License for the Production and Operation of Radio and Television Program. The contractual arrangements contain terms that specifically obligate VIEs’ shareholders to ensure the valid existence of the VIEs and restrict the disposal of material assets of the VIEs. However, in the event the VIEs’ shareholders breach the terms of these contractual arrangements and voluntarily liquidate the VIEs, or the VIEs declare bankruptcy and all or part of its assets become subject to liens or rights of third-party creditors, or are otherwise disposed of without our consent, we may be unable to conduct some or all of our business operations or otherwise benefit from the assets held by the VIEs, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, if the VIEs undergo a voluntary or involuntary liquidation proceeding, its shareholders or unrelated third-party creditors may claim rights to some or all of the assets of the VIEs, thereby hindering our ability to operate our business as well as constrain our growth.

Certain of our existing shareholders have substantial influence over our company, and their interests may not be aligned with the interests of our other stockholders.

Mr. Peng Ou, our founder and the chairman of our Board of Directors, owns approximately 57.1% of our voting power and Mr. Tongbo Liu, our director and our Chief Executive Officer, owns approximately 21.6% of our voting power as of the date of this annual report. In addition, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees collectively beneficially own all of our issued and outstanding Class C ordinary shares which constitute approximately 83.4% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report. In addition, up to 433,053 ordinary shares reserved and issuable upon the exercise of options granted pursuant to our equity incentive plan adopted in October 2017 shall be, upon issuance of such ordinary shares, designated as Class C ordinary shares, the voting power of which will be held by certain of our senior employees. See “—Risks Related to the ADSs—Our triple-class share structure with different voting rights will limit your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial.” As a result, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees have significant influence over our business, including decisions regarding mergers, consolidations, liquidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. This concentration of ownership may also have the effect of discouraging, delaying or preventing a future change of control, which could deprive our stockholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of the ADSs.

The approval, filing or other requirements of the China Securities Regulatory Commission or other PRC government authorities may be required under PRC law in connection with our issuance of securities overseas.

The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, purport to require offshore special purpose vehicles that are controlled by PRC companies or individuals and that have been formed for the purpose of seeking a public listing on an overseas stock exchange through acquisitions of PRC domestic companies or assets to obtain CSRC approval prior to publicly listing their securities on an overseas stock exchange. The interpretation and application of the regulations remain unclear. If CSRC approval under the M&A Rules is required, it is uncertain whether it would be possible for us to obtain the approval, and any failure to obtain or delay in obtaining CSRC approval for our future issuance of securities overseas would subject us to sanctions imposed by the CSRC and other PRC regulatory agencies.

Furthermore, the Opinions on Strictly Cracking Down on Illegal Securities Activities emphasized the need to strengthen the administration over “illegal securities activities” and the supervision on overseas listings by China-based companies, and proposed to take effective measures, such as promoting the construction of relevant regulatory systems to deal with the risks and incidents faced by China-based overseas-listed companies, although such opinions did not specify the definition of “illegal securities activities.” Such opinions further provided that the special provisions of the State Council on overseas offerings and listings by those companies limited by shares will be revised and therefore the duties of domestic industry competent authorities and regulatory agencies will be clarified.

As these opinions were newly issued and there are no further explanations or detailed rules and regulations with respect to such opinions, there are still uncertainties regarding the interpretation and implementation of such opinions.

In addition, we cannot guarantee that new rules or regulations promulgated in the future will not impose any additional requirement on us or otherwise tightening the regulations on companies with a VIE structure. On December 24, 2021, the CSRC issued the Provisions of the State Council on the Administration of Overseas Securities Offering and Listing by Domestic Companies (Draft for Comments) and the Administrative Measures for the Filing of Overseas Securities Offering and Listing by Domestic Companies (Draft for Comments), collectively the Draft Overseas Listing Regulations, for public comments, which require, among others, that PRC domestic companies that seek to offer and list securities in overseas markets, either in direct or indirect means, are required to file the required documents with the CSRC within three working days after its application for overseas listing is submitted. As of the date of this annual report, the Draft Overseas Listing Regulations were released for public comments only and the final version and effective date of such regulations are subject to change with substantial uncertainty. If the CSRC, or other relevant PRC regulatory agencies subsequently determine that prior approval is required for any of our future offerings of securities overseas or to maintain the listing status of our ADSs, we cannot guarantee that we will be able to obtain such approval in a timely manner, or at all. The CSRC or other PRC regulatory agencies also may take actions requiring us, or making it advisable for us, not to proceed with such offering or maintain the listing status of our ADSs. If we proceed with any of such offering or maintain the listing status of our ADSs

without obtaining the CSRC’s approval to the extent it is required, or if we are unable to comply with any new approval requirements which might be adopted for offerings that we have completed prior to the publication of the above- referenced opinions, we may face regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our ability to pay dividends outside of China, limit our operating privileges in China, delay or restrict the repatriation of the proceeds from offering of securities overseas into China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of the ADSs.

Furthermore, if there are any other approvals, filings and/or other administration procedures to be obtained from or completed with the CSRC or other PRC regulatory agencies as required by any new laws and regulations for any of our future proposed offering of securities overseas or the listing of the ADSs, we cannot assure you that we can obtain the required approval or complete the required filings or other regulatory procedures in a timely manner, or at all. Any failure to obtain the relevant approvals or complete the filings and other relevant regulatory procedures may subject us to regulatory actions or other sanctions from the CSRC or other PRC regulatory agencies, which may have a material adverse effect on our business, financial condition or results of operations.

Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business and operations.

Substantially all of our assets and operations are located in China. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally. The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over China’s economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Meanwhile, economic conditions in China are sensitive to global economic conditions, changes in domestic economic and political policies and the expected or perceived overall economic growth rate in China. There have been concerns over the relationship among China and other Asian countries, which may result in or intensify potential conflicts in relation to territorial disputes, and the trade disputes between the United States and China. It is unclear whether these challenges and uncertainties will be contained or resolved, and what effects they may have on the global political and economic conditions in the long term.

While the Chinese economy has experienced significant growth over past decades, growth has been uneven, both geographically and among various sectors of the economy. Any adverse changes in economic conditions in China, in the policies of the Chinese government or in the laws and regulations in China could have a material adverse effect on the overall economic growth of China. Such developments could adversely affect our business and operating results, lead to a reduction in demand for our services and adversely affect our competitive position. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations. In addition, in the past the Chinese government has implemented certain measures, including interest rate adjustment, to control the pace of economic growth. These measures may cause decreased economic activity in China, which may adversely affect our business and operating results.

Uncertainties with respect to the PRC legal system, including uncertainties regarding the enforcement of laws, and sudden or unexpected changes in policies, laws and regulations in China, could adversely affect us.

The PRC legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions under the civil law system may be cited for reference but have limited precedential value.

In 1979, the PRC government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation over the past three decades has significantly enhanced the protections afforded to various forms of foreign investments in China. However, China has not developed a fully integrated legal system, and recently enacted laws and regulations may not sufficiently cover all aspects of economic activities in China. In particular, the interpretation and enforcement of these laws and regulations involve uncertainties. Since PRC

administrative and court authorities have significant discretion in interpreting and implementing statutory provisions and contractual terms, it may be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy. These uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or tort claims. In addition, the regulatory uncertainties may be exploited through unmerited or frivolous legal actions or threats in attempts to extract payments or benefits from us.

The PRC government has significant oversight and discretion over the conduct of our business and may intervene with or influence our operations as the government deems appropriate to further regulatory, political and societal goals. The PRC government has recently published new policies that adversely affected educational industry, espscially the educational services related to K-12 students, and we cannot rule out the possibility that it will in the future further release regulations or policies regarding educational industry that could further adversely affect our business, financial condition and results of operations. Furthermore, the PRC government has also recently indicated an intent to exert more oversight and control over securities offerings and other capital markets activities that are conducted overseas and foreign investment in China-based companies like us. Any such action, once taken by the PRC government, could significantly limit or completely hinder our ability to offer or continue to offer securities to investors and cause the value of such securities to significantly decline or in extreme cases, become worthless.

However, as there are still regulatory uncertainties in this regard, we cannot assure you that we will be able to comply with new laws and regulations in all respects in a timely manner, and we may be ordered to rectify, suspend or terminate any actions or services that are deemed illegal by the regulatory authorities and become subject to material penalties, which may materially harm our business, financial condition, results of operations and prospects.

Furthermore, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have a retroactive effect. As a result, we may not be aware of our violation of any of these policies and rules until sometime after the violation. In addition, any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention.

You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China against us or our management named in the annual report based on foreign laws.

We are an exempted company incorporated under the laws of the Cayman Islands, we conduct substantially all of our operations in China, and substantially all of our assets are located in China. In addition, all our senior executive officers reside within China for a significant portion of the time and most are PRC nationals. As a result, it may be difficult for our shareholders to effect service of process upon us or those persons inside China. In addition, China does not have treaties providing for the reciprocal recognition and enforcement of judgments of courts with the Cayman Islands and many other countries and regions. Therefore, recognition and enforcement in China of judgments of a court in any of these non-PRC jurisdictions in relation to any matter not subject to a binding arbitration provision may be difficult or impossible.

We may rely on dividends and other distributions on equity paid by our PRC subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our PRC subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business.

We are a Cayman Islands holding company and we rely principally on dividends and other distributions on equity from our PRC subsidiaries for our cash requirements, including for services of any debt we may incur. Our PRC subsidiary’s ability to distribute dividends is based upon its distributable earnings. Current PRC regulations permit our PRC subsidiaries to pay dividends to its respective shareholders only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, each of our PRC subsidiary, the VIEs and their respective subsidiaries are required to set aside at least 10% of its after-tax profits each year, if any, to fund a statutory reserve until such reserve reaches 50% of its registered capital. These reserves are not distributable as cash dividends. If our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to us. Any limitation on the ability of our PRC subsidiaries to distribute dividends or other payments to their respective shareholders could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our businesses, pay dividends or otherwise fund and conduct our business.

To address the persistent capital outflow and the RMB’s depreciation against the U.S. dollar in the fourth quarter of 2016, the People’s Bank of China and the State Administration of Foreign Exchange, or SAFE, implemented a series of capital control measures in the subsequent months, including stricter vetting procedures for China-based companies to remit foreign currency for overseas acquisitions, dividend payments and shareholder loan repayments. For instance, the Circular on Promoting the Reform of Foreign Exchange Management and Improving Authenticity and Compliance Review, or the SAFE

Circular 3, issued on January 26, 2017, provides that the banks shall, when dealing with dividend remittance transactions from domestic enterprise to its offshore shareholders of more than US$50,000, review the relevant board resolutions, original tax filing form and audited financial statements of such domestic enterprise based on the principal of genuine transaction. The PRC government may continue to strengthen its capital controls and our PRC subsidiaries’ dividends and other distributions may be subject to tightened scrutiny in the future. Any limitation on the ability of our PRC subsidiaries to pay dividends or make other distributions to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends, or otherwise fund and conduct our business.

In addition, the Enterprise Income Tax Law and its implementation rules provide that a withholding tax rate of up to 10% will be applicable to dividends payable by Chinese companies to non-PRC-resident enterprises unless otherwise exempted or reduced according to treaties or arrangements between the PRC central government and governments of other countries or regions where the non-PRC resident enterprises are incorporated.

The custodians or authorized users of our controlling non-tangible assets, including chops and seals, may fail to fulfill their responsibilities, or misappropriate or misuse these assets.

Under the PRC law, legal documents for corporate transactions, including agreements and contracts are executed using the chop or seal of the signing entity or with the signature of a legal representative whose designation is registered and filed with relevant PRC industry and commerce authorities.

In order to secure the use of our chops and seals, we have established internal control procedures and rules for using these chops and seals. In any event that the chops and seals are intended to be used, the responsible personnel will submit the application through our office automation system and the application will be verified and approved by authorized employees in accordance with our internal control procedures and rules. In addition, in order to maintain the physical security of our chops, we generally have them stored in secured locations accessible only to authorized employees. Although we monitor such authorized employees, the procedures may not be sufficient to prevent all instances of abuse or negligence. There is a risk that our employees could abuse their authority, for example, by entering into a contract not approved by us or seeking to gain control of one of our subsidiaries or consolidated VIEs. If any employee obtains, misuses or misappropriates our chops and seals or other controlling non-tangible assets for whatever reason, we could experience disruption to our normal business operations. We may have to take corporate or legal action, which could involve significant time and resources to resolve and divert management from our operations.

Fluctuations in exchange rates could have a material and adverse effect on our results of operations and the value of your investment.

The value of the Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by the PRC government. On July 21, 2005, the PRC government changed its policy of pegging the value of the Renminbi to the U.S. dollar. Following the removal of the U.S. dollar peg, the Renminbi appreciated more than 20% against the U.S. dollar over the following three years. Since June 2010, the Renminbi has started to appreciate slowly against the U.S. dollar, though there have been periods when the U.S. dollar has appreciated against the RMB. On August 11, 2015, the PBOC allowed the Renminbi to depreciate by approximately 2% against the U.S. dollar. Since then and until the end of 2016, the Renminbi has depreciated against the U.S. dollar by approximately 10%. It is difficult to predict how long such depreciation of RMB against the U.S. dollar may last and when and how the relationship between the RMB and the U.S. dollar may change again.

All of our revenue and substantially all of our costs are denominated in Renminbi. We are a holding company and we rely on dividends paid by our operating subsidiaries in China for our cash needs. Any significant revaluation of Renminbi may materially and adversely affect our results of operations and financial position reported in Renminbi when translated into U.S. dollars, and the value of, and any dividends payable on, the ADSs in U.S. dollars. To the extent that we need to convert U.S. dollars we receive from the initial public offering into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we would receive. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount.

Governmental control of currency conversion may limit our ability to utilize our net revenues effectively and affect the value of your investment.

The PRC government imposes controls on the convertibility of the Renminbi into foreign currencies and, in certain cases, the remittance of currency out of China. We receive substantially all of our revenues in Renminbi. Under our current corporate structure, our Cayman Islands holding company primarily relies on dividend payments from our PRC subsidiaries to fund any cash and financing requirements we may have. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval of SAFE by complying with certain procedural requirements. Specifically, under the existing exchange restrictions, without prior approval of SAFE, cash generated from the operations of our PRC subsidiaries in China may be used to pay dividends to our company. However, approval from or registration with appropriate government authorities is required where Renminbi is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of loans denominated in foreign currencies. As a result, we need to obtain SAFE approval to use cash generated from the operations of our PRC subsidiaries and VIEs to pay off their respective debt in a currency other than Renminbi owed to entities outside China, or to make other capital expenditure payments outside China in a currency other than Renminbi. The PRC government may at its discretion restrict access to foreign currencies for current account transactions in the future. If the foreign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be able to pay dividends in foreign currencies to our shareholders, including holders of the ADSs.

Certain PRC regulations may make it more difficult for us to pursue growth through acquisitions.

Among other things, the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, adopted by six PRC regulatory agencies in 2006 and amended in 2009, established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time-consuming and complex. Such regulation requires, among other things, that the MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor acquires control of a PRC domestic enterprise or a foreign company with substantial PRC operations, if certain thresholds under the Provisions on Thresholds for Prior Notification of Concentrations of Undertakings, issued by the State Council in 2008 and amended in 2018, are triggered. Moreover, the Anti-Monopoly Law promulgated by the Standing Committee of the National People’s Congress which became effective in 2008 requires that transactions which are deemed concentrations and involve parties with specified turnover thresholds must be cleared by the relevant governmental authorities before they can be completed. On February 7, 2021, the Anti-monopoly Commission of the State Council, published the Anti-Monopoly Guidelines for the Internet Platform Economy Sector that aims at specifying some of the circumstances under which an activity of internet platforms may be identified as monopolistic act as well as setting out merger controlling filing procedures involving variable interest entities. In addition, PRC national security review rules which became effective in September 2011 require acquisitions by foreign investors of PRC companies engaged in military related or certain other industries that are crucial to national security be subject to security review before consummation of any such acquisition. The Measures for the Security Review of Foreign Investments promulgated by the National Development and Reform Commission and MOFCOM which became effective from January 2021 further requires that security review by relevant governmental authorities shall be conducted in accordance with the provisions of the Measures for foreign investments that affect or may affect national security. We may pursue potential strategic acquisitions that are complementary to our business and operations. Complying with the requirements of these regulations to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval or clearance from the MOFCOM, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share.

PRC regulations relating to the establishment of offshore special purpose companies by PRC residents may subject our PRC resident beneficial owners or our PRC subsidiary to liability or penalties, limit our ability to inject capital into our PRC subsidiary, limit our PRC subsidiary’s ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us.

In July 2014, SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment Through Special Purpose Vehicles, or SAFE Circular 37, to replace the Notice on Relevant Issues Concerning Foreign Exchange Administration for Domestic Residents’ Financing and Roundtrip Investment Through Offshore Special Purpose Vehicles, or SAFE Circular 75, which ceased to be effective upon the promulgation of SAFE Circular 37. SAFE Circular 37 requires PRC residents (including PRC individuals and PRC corporate entities) to register with SAFE or its local branches in connection with their direct or indirect offshore investment activities. SAFE Circular 37 is applicable to our shareholders who are PRC residents and may be applicable to any offshore acquisitions that we make in the future.

Under SAFE Circular 37, PRC residents who make, or have prior to the implementation of SAFE Circular 37 made, direct or indirect investments in offshore special purpose vehicles, or SPVs, will be required to register such investments with SAFE or its local branches. In addition, any PRC resident who is a direct or indirect shareholder of an SPV is required to update its filed registration with the local branch of SAFE with respect to that SPV, to reflect any material change. Moreover, any subsidiary of such SPV in China is required to urge the PRC resident shareholders to update their registration with the local branch of SAFE. If any PRC shareholder of such SPV fails to make the required registration or to update the previously filed registration, the subsidiary of such SPV in China may be prohibited from distributing its profits or the proceeds from any capital reduction, share transfer or liquidation to the SPV, and the SPV may also be prohibited from making additional capital contributions into its subsidiary in China. On February 13, 2015, the SAFE promulgated a Notice on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, or SAFE Notice 13, which became effective on June 1, 2015. Under SAFE Notice 13, applications for foreign exchange registration of inbound foreign direct investments and outbound overseas direct investments, including those required under SAFE Circular 37, will be filed with qualified banks instead of SAFE. The qualified banks will directly examine the applications and accept registrations under the supervision of SAFE. SAFE Notice 13 further provides that annual inspection of inbound foreign direct investments and outbound overseas direct investments is canceled. Instead, relevant entities or individuals, as the case may be, shall register data and information with respect to their inbound foreign direct investments and outbound overseas direct investment interests with SAFE.

We have requested our shareholders that we are aware of being subject to SAFE regulations to make all necessary registrations, filings and amendments with the local SAFE branch or qualified banks as required by SAFE Circular 37. We cannot assure you, however, that all of these individuals may continue to make required registrations, filings or updates on a timely manner, or at all. We can provide no assurance that we are or will in the future continue to be informed of identities of all PRC residents holding direct or indirect interest in our company. Any failure or inability by such individuals to comply with SAFE regulations may subject us to fines or legal sanctions, such as restrictions on our cross-border investment activities or our PRC subsidiary’s ability to distribute dividends to, or obtain foreign exchange-denominated loans from, our company or prevent us from making distributions or paying dividends. As a result, our business operations and our ability to make distributions to you could be materially and adversely affected.

Furthermore, as these foreign exchange regulations are still relatively new and their interpretation and implementation has been constantly evolving, it is unclear how these regulations, and any future regulation concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant government authorities. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our financial condition and results of operations. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the necessary filings and registrations required by the foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

Any failure to comply with PRC regulations regarding the registration requirements for employee stock incentive plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, replacing earlier rules promulgated in 2007. Pursuant to these rules, PRC citizens and non-PRC citizens who reside in China for a continuous period of not less than one year who participate in any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be the PRC subsidiaries of such overseas-listed company, and complete certain other procedures. In addition, an overseas-entrusted institution must be retained to handle matters in connection with the exercise or sale of stock options and the purchase or sale of shares and interests. We and our executive officers and other employees who are PRC citizens or who reside in the PRC for a continuous period of not less than one year and who have been granted options will be subject to these regulations because we are an overseas-listed company. Failure to complete the SAFE registrations may subject them to fines and legal sanctions, there may be additional restrictions on the ability of them to exercise their stock options or remit proceeds gained from sale of their stock into the PRC. We also face regulatory uncertainties that could restrict our ability to adopt additional incentive plans for our directors, executive officers and employees under PRC law. See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations on Foreign Exchange—Regulations on Stock Incentive Plans.”

If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and ADS holders.

Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside of the PRC with its “de facto management body” within the PRC is considered a “resident enterprise” and will be subject to the enterprise income tax on its global income at the rate of 25%. The implementation rules define the term “de facto management body” as the body that exercises full and substantial control and overall management over the business, productions, personnel, accounts and properties of an enterprise. In 2009, the State Administration of Taxation, or SAT, issued a circular, known as SAT Circular 82, which provides certain specific criteria for determining whether the “de facto management body” of a PRC-controlled enterprise that is incorporated offshore is located in China. Although this circular only applies to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in the circular may reflect the SAT’s general position on how the “de facto management body” text should be applied in determining the tax resident status of all offshore enterprises. According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be regarded as a PRC tax resident by virtue of having its “de facto management body” in China, and will be subject to PRC enterprise income tax on its global income only if all of the following conditions are met: (i) the primary location of the day-to-day operational management is in the PRC; (ii) decisions relating to the enterprise’s financial and human resource matters are made or are subject to approval by organizations or personnel in the PRC; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholder resolutions are located or maintained in the PRC; and (iv) at least 50% of voting board members or senior executives habitually reside in the PRC.

We believe our company is not a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.” If the PRC tax authorities determine that our company is a PRC resident enterprise for enterprise income tax purposes, we will be subject to PRC enterprise income on our worldwide income at the rate of 25%. Furthermore, we be required to withhold a 10% withholding tax from dividends we pay to our shareholders that are non-resident enterprises, including the holders of the ADSs. In addition, non-resident enterprise shareholders (including the ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including the ADS holders) and any gain realized on the transfer of ADSs or ordinary shares by such shareholders may be subject to PRC tax at a rate of 20% (which, in the case of dividends, may be withheld at source by us). These rates may be reduced by an applicable tax treaty, but it is unclear whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event that we are treated as a PRC resident enterprise. Any such tax may reduce the returns on your investment in the ADSs or ordinary shares.

We face uncertainty with respect to indirect transfers of equity interests in PRC resident enterprises by their non-PRC holding companies.

On February 3, 2015, the SAT issued the Public Notice Regarding Certain Corporate Income Tax Matters on Indirect Transfer of Properties by Non-Tax Resident Enterprises, or SAT Bulletin 7. SAT Bulletin 7 extends its tax jurisdiction to transactions involving the transfer of taxable assets through offshore transfer of a foreign intermediate holding company. In addition, SAT Bulletin 7 has introduced safe harbors for internal group restructurings and the purchase and sale of equity through a public securities market. SAT Bulletin 7 also brings challenges to both foreign transferor and transferee (or other person who is obligated to pay for the transfer) of taxable assets.

On October 17, 2017, the SAT issued the Announcement of the State Administration of Taxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source, or SAT Bulletin 37, which came into effect on December 1, 2017. The SAT Bulletin 37 further clarifies the practice and procedure of the withholding of non-resident enterprise income tax.

Where a non-resident enterprise transfers taxable assets indirectly by disposing of the equity interests of an overseas holding company, which is an Indirect Transfer, the non-resident enterprise as either transferor or transferee, or the PRC entity that directly owns the taxable assets, may report such Indirect Transfer to the relevant tax authority. Using a “substance over form” principle, the PRC tax authority may disregard the existence of the overseas holding company if it lacks a reasonable commercial purpose and was established for the purpose of reducing, avoiding or deferring PRC tax. As a result, gains derived from such Indirect Transfer may be subject to PRC enterprise income tax, and the transferee or other person who is obligated to pay for the transfer is obligated to withhold the applicable taxes, currently at a rate of 10% for the transfer

of equity interests in a PRC resident enterprise. Both the transferor and the transferee may be subject to penalties under PRC tax laws if the transferee fails to withhold the taxes and the transferor fails to pay the taxes.

We face uncertainties as to the reporting and other implications of certain past and future transactions where PRC taxable assets are involved, such as offshore restructuring, sale of the shares in our offshore subsidiaries and investments. Our company may be subject to filing obligations or taxed if our company is transferor in such transactions, and may be subject to withholding obligations if our company is transferee in such transactions, under SAT Bulletin 7 and/or SAT Bulletin 37. For transfer of shares in our company by investors who are non-PRC resident enterprises, our PRC subsidiaries may be requested to assist in the filing under SAT Bulletin 7 and/or SAT Bulletin 37. As a result, we may be required to expend valuable resources to comply with SAT Bulletin 7 and/or SAT Bulletin 37 or to request the relevant transferors from whom we purchase taxable assets to comply with these circulars, or to establish that our company should not be taxed under these circulars, which may have a material adverse effect on our financial condition and results of operations.

Uncertainties exist with respect to the interpretation and implementation of the newly enacted Foreign Investment Law and how it may impact our business, financial condition and results of operations.

On March 15, 2019, the National People’s Congress promulgated the Foreign Investment Law, which came into effect on January 1, 2020 and replaced the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The Foreign Investment Law embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. The enacted Foreign Investment Law does not touch upon the relevant concepts and regulatory regimes of “actual control” in determining whether a company is considered a foreign invested enterprise, and thus this regulatory topic remains unclear under the Foreign Investment Law. On December 26, 2019, the State Council published the Implementation Rules of Foreign Investment Law, which came into effect on January 1, 2020. The Implementation Rules of Foreign Investment Law restates certain principles of the Foreign Investment Law. However, since the Foreign Investment Law and the Implementation Rules of Foreign Investment Law are relatively new, uncertainties still exist in relation to its interpretation and implementation. For instance, though the Foreign Investment Law does not explicitly classify contractual arrangements as a form of foreign investment, it contains a catch-all provision under the definition of “foreign investment,” which includes investments made by foreign investors in China through means stipulated in laws or administrative regulations or other methods prescribed by the State Council. Therefore, it still leaves leeway for future laws, administrative regulations or provisions promulgated by the State Council to provide for contractual arrangements as a form of foreign investment. Furthermore, if future laws, administrative regulations or provisions prescribed by the State Council mandate further actions to be taken by companies with respect to existing contractual arrangements, such as unwinding our existing contractual arrangements and/or disposal of our related business operations, we may face substantial uncertainties as to whether we can complete such actions in a timely manner, or at all. Failure to take timely and appropriate measures to cope with any of these or similar regulatory compliance challenges could materially and adversely affect our current corporate structure, financial condition and business operations.

The PCAOB is currently unable to inspect our auditor in relation to their audit work performed for our financial statements and the inability of the PCAOB to conduct inspections over our auditor deprives our investors with the benefits of such inspections.

Our auditor, the independent registered public accounting firm that issues the audit report included elsewhere in this annual report, as an auditor of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board (United States), or the PCAOB, is subject to laws in the United States pursuant to which the PCAOB conducts regular inspections to assess its compliance with the applicable professional standards. Since our auditor is located in China, a jurisdiction where the PCAOB has been unable to conduct inspections without the approval of the Chinese authorities, our auditor is not currently inspected by the PCAOB.

This lack of the PCAOB inspections in China prevents the PCAOB from fully evaluating audits and quality control procedures of our independent registered public accounting firm. As a result, we and investors in our ADSs are deprived of the benefits of such PCAOB inspections.

The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our independent registered public accounting firm’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to the PCAOB inspections, which could cause investors and potential

investors in our ADSs to lose confidence in our audit procedures and reported financial information and the quality of our financial statements.

Our ADSs will be delisted and our ADSs and shares will be prohibited from trading in the over-the-counter market under the Holding Foreign Companies Accountable Act, or the HFCAA, if the PCAOB is unable to inspect or fully investigate auditors located in China.

As part of a continued regulatory focus in the United States on access to audit and other information currently protected by national law, in particular China’s, the Holding Foreign Companies Accountable Act, or the HFCAA has been signed into law on December 18, 2020. The HFCAA states if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspection for the PCAOB for three consecutive years beginning in 2021, the SEC shall prohibit our ADS from being traded on a national securities exchange or in the over-the-counter trading market in the U.S. Accordingly, under the current law this could happen in 2024. If this happens, there is no certainty that we will be able to list our ADSs on a non-U.S. exchange or that a market for our shares will develop outside of the U.S. The delisting of our ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.

On December 2, 2021, the SEC adopted final amendments to its rules implementing the HFCAA (the “Final Amendments”). The Final Amendments include requirements to disclose information, including the auditor name and location, the percentage of shares of the issuer owned by governmental entities, whether governmental entities in the applicable foreign jurisdiction with respect to the auditor has a controlling financial interest with respect to the issuer, the name of each official of the Chinese Communist Party who is a member of the board of the issuer, and whether the articles of incorporation of the issuer contains any charter of the Chinese Communist Party. The Final Amendments also establish procedures the SEC will follow in identifying issuers and prohibiting trading by certain issuers under the HFCAA.

On December 16, 2021, PCAOB issued the HFCAA Determination Report, according to which our auditor is subject to the determinations that the PCAOB is unable to inspect or investigate completely. In March 2022, the SEC issued its first “conclusive list of issuers identified under the HFCAA” indicating that those companies are now formally subject to the delisting provisions if they remain on the list for three consecutive years. We anticipate being added to the list shortly after the filing of this annual report on Form 20-F.

The HFCAA or other efforts to increase U.S. regulatory access to audit information could cause investor uncertainty for affected issuers, including us, and the market price of the ADSs could be adversely affected. Additionally, whether the PCAOB will be able to conduct inspections of our auditor before the issuance of our financial statements on Form 20-F for the year ended December 31, 2023, which is due by April 30, 2024, or at all, is subject to substantial uncertainty and depends on factors out of our and our auditor’s control. If our auditor is unable to be inspected in time, we could be delisted from the New York Stock Exchange and our ADSs will not be permitted for trading “over-the-counter” either. Such a delisting would substantially impair your ability to sell or purchase our ADSs when you wish to do so, and the risk and uncertainty associated with delisting would have a negative impact on the price of our ADSs. Also, such a delisting would significantly affect our ability to raise capital on terms acceptable to us, or at all, which would have a material adverse impact on our business, financial condition and prospects.

The potential enactment of the Accelerating Holding Foreign Companies Accountable Act would decrease the number of non-inspection years from three years to two, thus reducing the time period before our ADSs may be prohibited from over-the-counter trading or delisted. If this bill were enacted, our ADSs could be delisted from the exchange and prohibited from over-the-counter trading in the U.S. in 2023.

On June 22, 2021, the U.S. Senate passed a bill known as the Accelerating Holding Foreign Companies Accountable Act, to amend Section 104(i) of the Sarbanes-Oxley Act of 2002 (15 U.S.C. 7214(i)) to prohibit securities of any registrant from being listed on any of the U.S. securities exchanges or traded over-the-counter if the auditor of the registrant’s financial statements is not subject to PCAOB inspection for two consecutive years, instead of three consecutive years as currently enacted in the HFCAA.

On February 4, 2022, the U.S. House of Representatives passed the America Competes Act of 2022 which includes the exact same amendments as the bill passed by the Senate. The America Competes Act however includes a broader range of legislation not related to the HFCAA in response to the U.S. Innovation and Competition Act passed by the Senate in 2021. The U.S. House of Representatives and U.S. Senate will need to agree on amendments to these respective bills to align the legislation and pass their amended bills before the President can sign into law. It is unclear when the U.S. Senate and U.S.

House of Representatives will resolve the differences in the U.S. Innovation and Competition Act and the America Competes Act of 2022 bills currently passed, or when the U.S. President will sign on the bill to make the amendment into law, or at all.

In the case that the bill becomes the law, it will reduce the time period before our ADSs could be delisted from the exchange and prohibited from over-the-counter trading in the U.S. from 2024 to 2023.

Proceedings instituted by the SEC against Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act.

Starting in 2011 the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, were affected by a conflict between U.S. and Chinese law. Specifically, for certain U.S.-listed companies operating and audited in mainland China, the SEC and the PCAOB sought to obtain from the Chinese firms access to their audit work papers and related documents. The firms were, however, advised and directed that under Chinese law, they could not respond directly to the U.S. regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channeled through the CSRC.

In late 2012, this impasse led the SEC to commence administrative proceedings under Rule 102E of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the Chinese accounting firms, including our independent registered public accounting firm. A first instance trial of the proceedings in July 2013 in the SEC’s internal administrative court resulted in an adverse judgment against the firms. The administrative law judge proposed penalties on the firms including a temporary suspension of their right to practice before the SEC, although that proposed penalty did not take effect pending review by the Commissioners of the SEC. On February 6, 2015, before a review by the Commissioner had taken place, the firms reached a settlement with the SEC. Under the settlement, the SEC accepted that future requests by the SEC for the production of documents would normally be made to the CSRC. The firms would receive matching Section 106 requests, and would be required to abide by a detailed set of procedures with respect to such requests, which in substance would require them to facilitate production via the CSRC. If they fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm’s performance of certain audit work, commencement of a new proceeding against a firm, or, in extreme cases, the resumption of the current proceeding against all four firms. If additional remedial measures are imposed on the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, in administrative proceedings brought by the SEC alleging the firms’ failure to meet specific criteria set by the SEC with respect to requests for the production of documents, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act.

Under the terms of the settlement, the underlying proceeding against the four PRC-based accounting firms was deemed dismissed with prejudice at the end of four years starting from the settlement date, which was on February 6, 2019. Despite the final ending of the proceedings, the presumption is that all parties will continue to apply the same procedures, i.e. the SEC will continue to make its requests for the production of documents to the CSRC, and the CSRC will normally process those requests applying the sanitization procedure. We cannot predict whether, in cases where the CSRC does not authorize production of requested documents to the SEC, the SEC will further challenge the four PRC-based accounting firms’ compliance with U.S. law. If additional challenges are imposed on the Chinese affiliates of the “big four” accounting firms, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, U.S.-listed companies, and the market price of our ordinary shares may be adversely affected.

If our independent registered public accounting firm was denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of the ADSs from the New York Stock Exchange or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of the ADSs in the United States.

Regulation and censorship of information disseminated over the internet in China may adversely affect our business and reputation and subject us to liability for information displayed on our website.

The PRC government has adopted regulations governing internet access and the distribution of news and other information over the internet. Under these regulations, internet content providers and internet publishers are prohibited from posting or displaying over the internet content that, among other things, violates PRC laws and regulations, impairs the national dignity of China, or is reactionary, obscene, superstitious, fraudulent or defamatory. Failure to comply with these requirements may result in the revocation of licenses to provide internet content and other licenses, and the closure of the concerned websites. The website operator may also be held liable for such censored information displayed on or linked to the websites. If our website is found to be in violation of any such requirements, we may be penalized by relevant authorities, and our operations or reputation could be adversely affected.

It may be difficult for overseas regulators to conduct investigation or collect evidence within China.

Shareholder claims or regulatory investigation that are common in the United States generally are difficult to pursue as a matter of law or practicality in China. For example, in China, there are significant legal and other obstacles to providing information needed for regulatory investigations or litigation initiated outside China. Although the authorities in China may establish a regulatory cooperation mechanism with the securities regulatory authorities of another country or region to implement cross-border supervision and administration, such cooperation with the securities regulatory authorities in the Unities States may not be efficient in the absence of mutual and practical cooperation mechanism. Furthermore, Article 177 of the PRC Securities Law, or Article 177, which became effective in March 2020, prohibits, without the approval of the securities regulatory authority in China, (i) foreign securities regulators from engaging in any inspection activities within China and (ii) anyone from providing any documents or materials relating to capital markets activities to foreign parties. While detailed interpretation of or implementation rules under Article 177 have yet to be promulgated, the inability for an overseas securities regulator to directly conduct investigation or evidence collection activities within China may further increase difficulties faced by you in protecting your interests. See also “You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law” for risks associated with investing in us as a Cayman Islands company.

If the market price for our ADSs falls below US$1.00 for an extended period of time, or falls to US$0.16 at any time, our ADSs may be delisted from the NYSE.

Pursuant to NYSE Rule 802.01C, a company will be considered to be below complaince standards if the average closing price of a security as reported on the consolidated tape is less than US$1.00 over a consecutive 30 trading-day period. Once notified, the company must bring its share price and average share price back above US$1.00 within the applicable cure period following receipt of the notification. The company can regain compliance at any time during the cure period if on the last trading day of any calendar month during the cure period the company has a closing share price of at least US$1.00 and an average closing share price of at least US$1.00 over the 30 trading-day period ending on the last trading day of that month. In the event that at the expiration of the cure period, both a US$1.00 closing share price on the last trading day of the cure period and a US$1.00 average closing share price over the 30 trading-day period ending on the last trading day of the cure period are not attained, the NYSE will commence suspension and delisting procedures. In addition, we understand that the NYSE has a policy to suspend trading immediately and commence delisting procedures if the market price of securities falls to US$0.16 or less. We received a letter from the NYSE dated July 23, 2021 notifying us that the stock prices of our ADSs are below compliance standards due to the fact that the average closing price of our ADSs was less than $1.00 for a consecutive 30 trading-day period. In response to the letter from the NYSE, we changed the ratio of the ADSs representing our Class A ordinary shares from 25 ADSs representing one Class A ordinary share to two ADSs representing one Class A ordinary share, effective August 31, 2021. However, we cannot assure you that our ADSs will remain in compliance with the NYSE listing rules going forward. If our ADSs are delisted from the NYSE, the liquidity and value of an investment in our ADSs will be materially and adversely affected.

The trading price of the ADSs is likely to be volatile, which could result in substantial losses to investors.

The trading price of the ADSs is likely to be volatile and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, including the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the United States. In addition to market and industry factors, the price and trading volume for the ADSs may be highly volatile for factors specific to our own operations, including the following:

In the past, shareholders of public companies have often brought securities class action suits against those companies following periods of instability in the market price of their securities. If we were involved in a class action suit, it could divert a significant amount of our management’s attention and other resources from our business and operations and require us to incur significant expenses to defend the suit, which could harm our results of operations. Any such class action suit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully made against us, we may be required to pay significant damages, which could have a material adverse effect on our financial condition and results of operations.

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding the ADSs, the market price for the ADSs and trading volume could decline.

The trading market for the ADSs will be influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade the ADSs, the market price for the ADSs would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the market price or trading volume for the ADSs to decline.

The sale or availability for sale of substantial amounts of ADSs could adversely affect their market price.

Sales of substantial amounts of the ADSs in the public market, or the perception that these sales could occur, could adversely affect the market price of the ADSs and could materially impair our ability to raise capital through equity offerings in the future. We cannot predict what effect, if any, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale will have on the market price of the ADSs.

Techniques employed by short sellers may drive down the market price of the ADSs.

Short selling is the practice of selling securities that the seller does not own but rather has borrowed from a third party with the intention of buying identical securities back at a later date to return to the lender. The short seller hopes to profit from a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares, as the short seller expects to pay less in that purchase than it received in the sale. As it is in the short seller’s interest for the price of the security to decline, many short sellers publish, or arrange for the publication of, negative opinions regarding the relevant issuer and its business prospects in order to create negative market momentum and generate profits for themselves after selling a security short. These short attacks have, in the past, led to selling of shares in the market.

Public companies that have substantially all of their operations in China have been the subject of short selling. Much of the scrutiny and negative publicity has centered on allegations of a lack of effective internal control over financial reporting resulting in financial and accounting irregularities and mistakes, inadequate corporate governance policies or a lack of adherence thereto and, in many cases, allegations of fraud. As a result, many of these companies are now conducting internal and external investigations into the allegations and, in the interim, are subject to shareholder lawsuits and/or enforcement actions by the SEC or other U.S. authorities.

It is not clear what effect such negative publicity could have on us. If we were to become the subject of any unfavorable allegations, whether such allegations are proven to be true or untrue, we could have to expend a significant amount of resources to investigate such allegations and/or defend ourselves. While we would strongly defend against any such short seller attacks, we may be constrained in the manner in which we can proceed against the relevant short seller by principles of freedom of speech, applicable state law or issues of commercial confidentiality. Such a situation could be costly and time-consuming, and could distract our management from growing our business. Even if such allegations are ultimately proven to be groundless, allegations against us could severely impact our business operations, and any investment in the ADSs could be greatly reduced or even rendered worthless.

Because we do not expect to pay dividends in the foreseeable future, you must rely on a price appreciation of the ADSs for a return on your investment.

We currently intend to retain most, if not all, of our available funds and any future earnings to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in the ADSs as a source for any future dividend income.

Our Board of Directors has complete discretion as to whether to distribute dividends, subject to certain requirements of Cayman Islands law. Under Cayman Islands law, a Cayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our Board of Directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our Board of Directors. Accordingly, the return on your investment in the ADSs will likely depend entirely upon any future price appreciation of the ADSs. There is no guarantee that the ADSs will appreciate in value or even maintain the price at which you purchased the ADSs. You may not realize a return on your investment in the ADSs and you may even lose your entire investment in the ADSs.

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law.

We are an exempted company incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Act (As Revised) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands have a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records (other than copies of the memorandum and articles of association, the register of mortgages and charges, and any special resolutions passed by the shareholders) or to obtain copies of lists of shareholders of these companies. Our directors have discretion under our articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests in the face of actions taken by our management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States.

Certain judgments obtained against us by our shareholders may not be enforceable.

We are a Cayman Islands exempted company and substantially all of our assets are located outside of the United States. Substantially all of our current operations are conducted in China. In addition, most of our current directors and officers are nationals and residents of countries other than the United States. Substantially all of the assets of these persons are located outside the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the U.S. federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to direct the voting of your Class A ordinary shares underlying the ADSs.

Holders of ADSs do not have the same rights as our registered shareholders. As a holder of the ADSs, you will not have any direct right to attend general meetings of our shareholders or to cast any votes at such meetings. You will only be able to exercise the voting rights which attach to the underlying Class A ordinary shares represented by your ADSs indirectly by giving voting instructions to the depositary in accordance with the provisions of the deposit agreement. Under the deposit agreement, you may vote only by giving voting instructions to the depositary, as holder of the underlying Class A ordinary shares represented by your ADSs. Upon receipt of your voting instructions, the depositary may try to vote the underlying Class A ordinary shares represented by your ADSs in accordance with your instructions. If we ask for your instructions, then upon receipt of your voting instructions, the depositary will try to vote the underlying Class A ordinary shares in accordance with those instructions. If we do not instruct the depositary to ask for your instructions, the depositary may still vote in accordance with instructions you give, but it is not required to do so. You will not be able to directly exercise any right to vote with respect to the underlying Class A ordinary shares unless you withdraw the shares and become the registered holder of such shares prior to the record date for the general meeting. When a general meeting is convened, you may not receive sufficient advance notice of the meeting to enable you to withdraw the underlying Class A ordinary shares represented by your ADSs and become the registered holder of such shares prior to the record date for the general meeting to allow you to attend the general meeting and to vote directly with respect to any specific matter or resolution to be considered and voted upon at the general meeting. In addition, under our fourth amended and restated articles of association, for the purposes of determining those shareholders who are entitled to attend and vote at any general meeting, our directors may close our register of members and/or fix in advance a record date for such meeting, and such closure of our register of members or the setting of such a record date may prevent you from withdrawing the Class A ordinary shares underlying your ADSs and becoming the registered holder of such shares prior to the record date, so that you would not be able to attend the general meeting or to vote directly. Where any matter is to be put to a vote at a general meeting, the depositary will notify you of the upcoming vote and to deliver our voting materials to you. We cannot assure you that you will receive the voting material in time to ensure you can direct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to direct how the underlying Class A ordinary shares represented by your ADSs are voted and you may have no legal remedy if the underlying Class A ordinary shares represented by your ADSs are not voted as you requested.

Our triple-class share structure with different voting rights will limit your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial.

We have adopted a triple-class share structure such that our ordinary shares consist of Class A ordinary shares, Class B ordinary shares and Class C ordinary shares. In respect of matters requiring the votes of shareholders, each Class A ordinary share is entitled to one vote, each Class B ordinary share is entitled to seven votes, and each Class C ordinary share is entitled to ten votes. Each Class B ordinary share or Class C ordinary share is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares or Class C ordinary shares, Class B ordinary shares are not convertible into Class C ordinary shares, and Class C ordinary shares are not convertible into Class B ordinary shares under any circumstances.

Mr. Peng Ou, our founder and chairman of our Board of Directors, Mr. Tongbo Liu, our chief executive officer and director, and certain of our senior management and employees collectively beneficially own all of our issued and outstanding Class C ordinary shares. These Class C ordinary shares constitute approximately 60.2% of our total issued and outstanding share capital and 84.0% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report. In addition, up to 433,053 ordinary shares reserved and issuable upon the exercise of options granted pursuant to our equity incentive plan adopted in October 2017 shall be, upon issuance of such ordinary shares, designated as Class C ordinary shares, the voting power of which will be held by certain of our senior employees. PV PLUTO LIMITED, an entity wholly owned and controlled by Primavera Capital Fund, beneficially owns all of our issued and outstanding Class B ordinary shares, which constitutes approximately 12.4% of our total issued and outstanding share capital and 12.1% of the aggregate voting power of our total issued and outstanding share capital as of the date of this annual report.

As a result of this triple-class share structure and the concentration of ownership, Mr. Peng Ou, Mr. Tongbo Liu and certain of our senior management and employees will have significant influence over our business, including decisions regarding mergers, consolidations, liquidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. They may take actions that are not in the best interest of us or our other shareholders. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could have the effect of depriving our other shareholders of the opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of the ADSs. This concentrated control will limit your ability to influence corporate matters and could discourage others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A ordinary shares and ADSs may view as beneficial.

Our triple-class voting structure may render the ADSs representing our class A ordinary shares ineligible for inclusion in certain stock market indices, and thus adversely affect the trading price and liquidity of the ADSs.

We cannot predict whether our triple-class share structure with different voting rights will result in a lower or more volatile market price of the ADSs, in adverse publicity, or other adverse consequences. Certain index providers have announced restrictions on including companies with multi-class share structures in certain of their indices. For example, S&P Dow Jones and FTSE Russell have changed their eligibility criteria for inclusion of shares of public companies on certain indices, including the S&P 500, to exclude companies with multiple classes of shares and companies whose public shareholders hold no more than 5% of total voting power from being added to such indices. As a result, our triple-class voting structure may prevent the inclusion of the ADSs representing our class A ordinary shares in such indices, which could adversely affect the trading price and liquidity of the ADSs representing our class A ordinary shares. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structure and our triple-class structure may cause shareholder advisory firms to publish negative commentary about our corporate governance, in which case the market price and liquidity of the ADSs could be adversely affected.

You may experience dilution of your holdings due to the inability to participate in rights offerings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parties, and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems it expedient in connection with the performance of its duties. The depositary may close

its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of the ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We are an emerging growth company within the meaning of the Securities Act and may take advantage of certain reduced reporting requirements.

We are an “emerging growth company,” as defined in the JOBS Act, and we have taken and intend to continue to take advantage of certain exemptions from requirements applicable to other public companies that are not emerging growth companies, including, most significantly, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 for so long as we remain an emerging growth company. As a result, if we elect to continue to not comply with such auditor attestation requirements, our investors may not have access to certain information they may deem important.

We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable to U.S. domestic public companies.

Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and regulations in the United States that are applicable to U.S. domestic issuers, including:

We are required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we intend to publish our results on a quarterly basis as press releases, distributed pursuant to the rules and regulations of the NYSE. Press releases relating to financial results and material events will also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC are less extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information that would be made available to you were you investing in a U.S. domestic issuer.

As an exempted company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the New York Stock Exchange corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with the New York Stock Exchange corporate governance listing standards.

As a Cayman Islands exempted company listed on the New York Stock Exchange, we are subject to New York Stock Exchange corporate governance listing standards. However, New York Stock Exchange rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the New York Stock Exchange corporate governance listing standards. We have followed and intend to continue to follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the New York Stock Exchange that listed companies must have: (i) a majority of independent directors; (ii) a nominating/corporate governance committee composed entirely of independent directors; and (iii) a compensation committee composed entirely of independent directors. To the extent we choose to follow home country practice in the future, our shareholders may be afforded less protection than they otherwise would enjoy under New York Stock Exchange corporate governance listing standards applicable to U.S. domestic issuers.

There can be no assurance that we will not be a passive foreign investment company, or PFIC, for any taxable year, which could result in adverse U.S. federal income tax consequences to U.S. investors in the ADSs or our ordinary shares.

In general, a non-U.S. corporation is a PFIC for U.S. federal income tax purposes for any taxable year in which (i) 75% or more of its gross income consists of passive income or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. For purposes of the above calculations, a non-U.S. corporation that owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Cash is a passive asset for these purposes. Based on the composition of our income and assets and the value of our assets, including goodwill, which is based on the price of our ADSs, we do not believe we were a PFIC for the 2021 taxable year. However, it is not entirely clear how the contractual arrangements between our wholly-owned PRC subsidiaries, our consolidated affiliated entities and the shareholders of our consolidated affiliated entities will be treated for purposes of the PFIC rules. Because the treatment of the contractual arrangements is not entirely clear, because we hold a substantial amount of cash and because our PFIC status for any taxable year will depend on the composition of our income and assets and the value of our assets from time to time (which may be determined, in part, by reference to the market price of the ADSs or ordinary shares, which could be volatile), there can be no assurance that we will not be a PFIC for our current or any future taxable year. If we were a PFIC for any taxable year during which a U.S. investor holds ADSs or ordinary shares, certain adverse U.S. federal income tax consequences could apply to such U.S. investor. See “Item 10. Additional Information—10.E. Taxation—Material U.S. Federal Income Tax Considerations—Passive Foreign Investment Company Rules.”

We commenced our education service business in August 2003. We remained an offline, classroom-based education service provider until we transitioned to an exclusively online education model in 2014.

In September 2015, Studyvip Online Education International Limited, our current ultimate holding company, was incorporated under the laws of the Cayman Islands. In October 2017, Studyvip Online Education International Limited was renamed as Sunlands Online Education Group. In August 2018, Sunlands Online Education Group was renamed as Sunlands Technology Group.

In October 2017, Sunlands Technology Group effectuated a one-for-two share split, pursuant to which each of its issued and outstanding ordinary shares and preferred shares was split into two ordinary shares or preferred shares, as the case may be.

In March 2018, we completed an initial public offering of 13,000,000 ADSs, representing 520,000 Class A ordinary shares and the ADSs were listed on the New York Stock Exchange under the symbol “STG.” In connection with our initial public offering, (i) DIAMOND TOWER INVESTMENTS LIMITED, our shareholder and an affiliate of Orchid Asia Group, purchased from us 104,348 Class A ordinary shares, and (ii) ELITE CONCEPT HOLDINGS LIMITED, our shareholder and an affiliate of New Oriental Education & Technology Group Inc., or New Oriental, purchased from us 34,783 Class A ordinary shares. These private placements are being made pursuant to Regulation S of the U.S. Securities Act of 1933, as amended.

In August 2021, we effected a reverse split of our ADSs. The ratio of our ADSs representing our Class A ordinary shares changed from each 25 ADSs representing one Class A ordinary share to each two ADSs representing one Class A ordinary share.

In December 2013, we entered into a series of contractual arrangements, which we refer to original VIE arrangements in this annual report, with Beijing Shangde Jiaxun Education Technology Co., Ltd., or Sunlands Jiaxun, and its shareholders. The original VIE arrangements enabled us to exercise effective control over Sunlands Jiaxun and its operating subsidiaries in the PRC, including the predecessor of Beijing Shangde Online Education Technology Co., Ltd., or Beijing Sunlands, a limited liability company through which we currently conduct our business in the PRC. During 2015 and 2016, as part of our plan to obtain equity financing in the PRC, we terminated the original VIE arrangements through a series of transactions.

In October 2015, our wholly owned subsidiary, Sunlands Online Education HK Limited, or Sunlands HK, was incorporated in Hong Kong.

In July 2017, Tianjin Studyvip Education Co., Limited, our wholly owned subsidiary, was incorporated in the PRC. It was renamed as Tianjin Alaman Education Technology Co., Ltd., or Tianjin Alaman, in February 2021. In August 2017, Sunlands HK established Wuhan Studyvip Online Education Co. Limited, or Wuhan Zhibo, our wholly owned subsidiary, in the PRC.

In August 2017, Wuhan Zhibo entered into a series of contractual agreements, including the Exclusive Technical Consultation and Service Agreement, the Business Operation Agreement, the Equity Interest Pledge Agreement, the Option Agreement, and the Powers of Attorney, with Beijing Sunlands and its shareholders. These contractual arrangements enable us to have effective control over, and receive the economic benefits of, Beijing Sunlands. Accordingly, we are considered the primary beneficiary of Beijing Sunlands and are able to consolidate Beijing Sunlands and its operating subsidiaries in the PRC.

In May 2018, Tianjin Alaman, our wholly-owned subsidiary, entered into a series of contractual arrangements with Tianjin Shangde Online Education Technology Co., Ltd, or Tianjin Shangde, as well as the shareholders of Tianjin Shangde and, where applicable, operating subsidiaries of Tianjin Shangde, through which we obtained effective control over, and became the primary beneficiary of, Tianjin Shangde.

From September 2019 to September 2020, Wuhan Zhibo, our wholly-owned subsidiary, entered into a series of contractual arrangements, including the Exclusive Technical Consultation and Service Agreements, the Business Operation Agreements, the Equity Interest Pledge Agreements, the Option Agreements, and the Powers of Attorney with, (i) Wuhan Xiaoyan Technology Co., Ltd., or Wuhan Xiaoyan, (ii) Wuhan Jiayan Online Education Technology Co., Ltd., or Wuhan Jiayan, (iii) Beijing Odysseus Education Technology Co., Ltd., or Beijing Odysseus, (iv) Guangzhou Wudawei Education Technology Co., Ltd., or Guangzhou Wudawei, (v) Guangzhou Tianyong Online Education Technology Co., Ltd., or Guangzhou Tianyong, and (vi) Wuhan Hadeliang Online Education Technology Co., Ltd., or Wuhan Hadeliang, as well as their shareholders and, where applicable, operating subsidiaries of them, through which we obtained effective control over, and became the primary beneficiary of, these companies.

In December 2020, as part of our efforts to streamline our corporate structure, (i) each of Tianjin Alaman, Tianjin Shangde and Tianjin Shangde’s shareholders executed termination agreements to terminate each of the contractual arrangements among them, as a result of which Tianjin Alaman no longer has effective control over, and receives the economic benefits of, Tianjin Shangde; and (ii) Wuhan Zhibo entered into a series of contractual arrangements, including the Exclusive Technical Consultation and Service Agreement, the Business Operation Agreement, the Equity Interest Pledge Agreement, the Option Agreement, and the Power of Attorney with Tianjin Shangde, as well as its shareholders and, where applicable, its operating subsidiaries, through which we obtained effective control over, and became the primary beneficiary of, Tianjin Shangde.

From December 2020 to February 2021, Tianjin Alaman, our wholly-owned subsidiary, entered into a series of contractual arrangements, including the Exclusive Technical Consultation and Service Agreements, the Business Operation Agreements, the Equity Interest Pledge Agreements, the Option Agreements, and Powers of Attorney with (i) Wuhan Fangtang Education Technology Co., Ltd., or Wuhan Fangtang, (ii) Beijing Zhiziyuanshui Education Technology Co., Ltd., or Beijing Zhiziyuanshui, and (iii) Beijing Feibian Education Technology Co., Ltd., or Beijing Feibian, as well as their shareholders and, where applicable, operating subsidiaries of them, through which we obtained effective control over, and became the primary beneficiary of, these companies.

In December 2020, Cheerwins Technology Group, or Cheerwins Cayman, our wholly owned subsidiary, was incorporated in Cayman. Its wholly owned subsidiary, Cheerwins Online Education HK limited, or Cheerwins HK, was incorporated in Hong Kong in January 2021. Cheerwins HK currently holds 100% of the equity interests of Tianjin Alaman.

In April 2021, FireSky Investment HK Limited, or FireSky Investment, our wholly owned subsidiary, was incorporated in Hong Kong. In June 2021, its wholly owned subsidiary, Wuhan Zhongtudao Technology Co., Ltd, or Wuhan Zhongtudao, was incorporated in the PRC.

In April 2021, due to the change of shareholders of Wuhan Jiayan, (i) each of the Wuhan Zhibo, Wuhan Jiayan and Wuhan Jiayan’s original shareholders executed termination agreements to terminate each of the contractual arrangements among them; (ii) Wuhan Zhibo entered into a series of contractual arrangements, including the Exclusive Technical Consultation and Service Agreement, the Business Operation Agreement, the Equity Interest Pledge Agreement, the Option Agreement, and the Power of Attorney with Wuhan Jiayan, as well as its new shareholder, through which we obtained effective control over, and became the primary beneficiary of, Wuhan Jiayan.

From April 2021 to June 2021, as part of our efforts to streamline our corporate structure, (i) each of Wuhan Zhibo, Wuhan Xiaoyan and Wuhan Xiaoyan’s shareholders executed a termination agreement to terminate each of the contractual arrangements among them, as a result of which Wuhan Zhibo no longer has effective control over, and receives the economic benefits of, Wuhan Xiaoyan; (ii) Wuhan Zhongtudao entered into a series of contractual arrangements, including the Exclusive Technical Consultation and Service Agreement, the Business Operation Agreement, the Equity Interest Pledge Agreement, the Option Agreement, and Powers of Attorney with Wuhan Xiaoyan, as well as its shareholders, through which we obtained effective control over, and became the primary beneficiary of, Wuhan Xiaoyan.

In May 2021, with the prior consent of the Wuhan Zhibo and the confirmation of the shareholders of Guangzhou Tianyong, Guangzhou Tianyong was deregistered, and the relevant contractual arrangements among each of Wuhan Zhibo, Guangzhou Tianyong and Guangzhou Tianyong’s shareholders were terminated. As a result, Wuhan Zhibo no longer has effective control over, and receives the economic benefits of, Guangzhou Tianyong.

In October 2021, Wuhan Zhibo, Guangzhou Wudawei and Guangzhou Wudawei’s shareholders executed a termination agreement to terminate the contractual arrangements among them, as a result of which Wuhan Zhibo no longer has effective control over, and receives the economic benefits of, Guangzhou Wudawei.

In November 2021, Beijing Lingding Management Consulting Co., Ltd., or Beijing Lingding, was incorporated in the PRC. In the same month, Wuhan Zhibo entered into a series of contractual arrangements, including the Exclusive Technical Consultation and Service Agreement, the Business Operation Agreement, the Equity Interest Pledge Agreement, the Option Agreement, and Powers of Attorney with Beijing Lingding, as well as its shareholders, through which we obtained effective control over, and became the primary beneficiary of, Beijing Lingding.

On December 6, 2021, we approved a share repurchase program under which our Company is authorized to repurchase up to US$15 million of Class A ordinary shares in the form of ADSs over the next 24 months.

Our corporate headquarters is located at Building 4-6, Chaolai Science Park, No. 36 Chuangyuan Road, Chaoyang District, Beijing, the People’s Republic of China. Our telephone number at this address is +86-10-52413738. Our registered office in the Cayman Islands is located at the offices of Maples Corporate Services Limited at PO Box 309, Ugland House, Grand Cayman KY1-1104, Cayman Islands. Our agent for service of process in the United States is Cogency Global Inc. located at 10 East 40th Street, 10th Floor, New York, N.Y. 10016. Our corporate website is www.sunlands.com. The information contained in our website is not a part of this annual report.

On January 4, 2022, the CAC published the Revised Cybersecurity Review Measures, which became effective on February 15, 2022 and repeal the Cybersecurity Review Measures promulgated on April 13, 2020. The Revised Cybersecurity Review Measures provide that a critical information infrastructure operator purchasing network products and services, and platform operators carrying out data processing activities, which affect or may affect national security, shall apply for cybersecurity review and that a platform operator with more than one million users’ personal information aiming to list abroad must apply for cybersecurity review. As the Revised Cybersecurity Review Measures is newly promulgated, it is uncertain how the measures will be interpreted or implemented and how they will affect us. We cannot predict the impact of the Revised Cybersecurity Review Measures, if any, at this stage, and we will closely monitor and assess any development in the rule-making process.

In anticipation of the strengthened implementation of cybersecurity laws and regulations and the continued expansion of our business, we face potential risks if we are deemed as a “critical information infrastructure operator” or “platform operator” under the PRC cybersecurity laws and regulations, and would be required to follow cybersecurity review procedures. During

such review, we may be required to suspend providing any existing or new services to our customers and/or experience other disruptions of our operations, and such review could also result in negative publicity with respect to our Company and diversion of our managerial and financial resources.

As of the date of this annual report, we have not been involved in any investigations or become subject to a cybersecurity review initiated by the CAC based on the Revised Cybersecurity Review Measures, and we have not received any inquiry, notice, warning, sanctions in such respect or any regulatory objections to our listing status from the CAC.

On July 6, 2021, certain PRC regulatory authorities issued Opinions on Strictly Cracking Down on Illegal Securities Activities. These opinions call for strengthened regulation over illegal securities activities and supervision on overseas listings by China-based companies and propose to take effective measures, such as promoting the development of relevant regulatory systems to deal with the risks and incidents faced by China-based overseas-listed companies. As of the date of this annual report, no official guidance and related implementation rules have been issued in relation to these recently issued opinions and the interpretation and implementation of these opinions remain unclear at this stage. We cannot assure you that we will not be required to obtain the approval of the CSRC or of potentially other regulatory authorities to maintain the listing status of our ADSs on the NYSE or to conduct offerings of securities in the future. We have been closely monitoring regulatory developments in China regarding any necessary approvals from the CSRC, the CAC, or other PRC regulatory authorities required for overseas listings. As of the date of this annual report, we have not received any inquiry, notice, warning, sanctions or regulatory objection from the CSRC.

Moreover, on December 24, 2021, the CSRC issued the Provisions of the State Council on the Administration of Overseas Securities Offering and Listing by Domestic Companies (Draft for Comments) and the Administrative Measures for the Filing of Overseas Securities Offering and Listing by Domestic Companies (Draft for Comments), collectively the Draft Overseas Listing Regulations, for public comments, which require, among others, that PRC domestic companies that seek to offer and list securities in overseas markets, either in direct or indirect means, are required to file the required documents with the CSRC within three working days after its application for overseas listing is submitted. As of the date of this annual report, the Draft Overseas Listing Regulations were released for public comments only and the final version and effective date of such regulations are subject to change with substantial uncertainty.

We are a Cayman Islands company and currently conduct substantially all of our business operations in the PRC through our subsidiaries incorporated in the PRC, and the VIEs. Our subsidiaries control the VIEs in the PRC, through a series of contractual arrangements. We conduct a significant portion of our businesses in China through the VIEs. It is the VIEs that hold our key operating licenses, provide services to our customers, and enter into contracts with our suppliers. We operate our businesses this way because PRC laws and regulations restrict foreign investment in companies that engage in value-added telecommunication services. These contractual arrangements entered into with the VIEs allow us to (i) exercise effective control over the VIEs, (ii) receive substantially all of the economic benefits of the VIEs, and (iii) have an exclusive option to purchase all or part of the equity interests in the VIEs when and to the extent permitted by PRC law. These contractual arrangements include the operating agreements, equity pledge agreements, exclusive purchase option agreements, shareholder voting right trust agreements, loan agreements, and cooperation agreements, as the case may be. As a result of these contractual arrangements, we exert effective control over, and are considered the primary beneficiary of, the VIEs and consolidate their operating results in our financial statements under U.S. GAAP.

We do not have any equity interests in the VIEs who are owned by certain nominee shareholders. As a result, control through these contractual arrangements may be less effective than direct ownership, and we could face heightened risks and costs in enforcing these contractual arrangements, because there are substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations, and rules relating to the legality and enforceability of these contractual arrangements. If the PRC government finds such agreements to be illegal, we could be subject to severe penalties or be forced to relinquish our interests in the VIEs.

Under relevant PRC laws and regulations, we are permitted to remit funds to the VIEs through loans rather than capital contributions. The VIEs funded their operations primarily using cash generated from operating and financing activities. In addition, Sunlands Technology Group and the VIEs may, from time to time, lend cash to each other to settle the payment obligations on each other’s behalf to provide temporary working capital support. In 2019, 2020 and 2021, the net amounts of

working capital support provided by our PRC subsidiaries to the VIEs were RMB1,110.4 million, RMB1,475.3 million and RMB12.5 million (US$2.0 million), respectively.

As of December 31, 2021, our PRC subsidiaries had made cumulative capital contributions of US$200.0 million to our PRC subsidiaries through an intermediate holding company. These funds have been used by our PRC subsidiaries for their operations. Our PRC subsidiaries maintained certain personnel for sales and marketing, research and development, and general and administrative functions to support the operations of the VIEs.

In 2019, 2020 and 2021, the VIEs transferred RMB1,230.2 million, RMB17.1 million and RMB62.6 million (US$9.8 million) of service fees to our PRC subsidiaries pursuant to the contractual arrangements, respectively. The outstanding balance of service fees owed by the VIEs to our PRC subsidiaries was nil as of each of December 31, 2019, 2020 and 2021. There were no other assets transferred between VIEs and non-VIEs in 2019, 2020 and 2021.

As advised by our PRC legal advisor, for any amounts owed by the VIEs to our PRC subsidiaries under the VIE agreements, unless otherwise required by PRC tax authorities, we are able to settle such amounts without limitations under the current effective PRC laws and regulations, provided that the VIEs have sufficient funds to do so and that the VIEs, in case in the form of non-enterprise institution, follow the principles of openness, fairness and impartiality, fix the price reasonably and regulate the decision-making, and do not damage the state interests, the interests of the non-enterprise institution or the rights and interests of the teachers and students when conducting such related party transaction. Sunlands Technology Group has not previously declared or paid any cash dividend or dividend in kind, and has no plan to declare or pay any dividends in the near future on our shares or the ADSs representing our ordinary shares. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business. See “Item 8.—Financial Information—8.A. Consolidated Statements and Other Financial Information—Dividend Policy.”

For the purpose of illustration, the below table reflects the hypothetical taxes that might be required to be paid within China, assuming that: (i) we have taxable earnings, and (ii) we determine to pay a dividend in the future:

(3) Certain of our subsidiaries and VIEs qualifies for a 15% preferential income tax rate in China. However, such rate is subject to qualification, is temporary in nature, and may not be available in a future period. For purposes of this hypothetical example, the table above reflects a maximum tax scenario under which the full statutory rate would be effective.

China’s Enterprise Income Tax Law imposes a withholding income tax of 10% on dividends distributed by a Foreign Invested Enterprises, or the FIE, to its immediate holding company outside of China. A lower withholding income tax rate of 5% is applied if the FIE’s immediate holding company is registered in Hong Kong or other jurisdictions that have a tax treaty arrangement with China, subject to a qualification review at the time of the distribution. For the purpose of this hypothetical example, this table has been prepared based on a taxation scenario under which the full withholding tax would be applied.

The table above has been prepared under the assumption that all profits of the VIEs will be distributed as fees to our PRC subsidiaries under tax neutral contractual arrangements. If in the future, the accumulated earnings of the VIEs exceed the fees paid to our PRC subsidiaries, or if the current and contemplated fee structure between the intercompany entities is determined

to be non-substantive and disallowed by Chinese tax authorities, we have other tax-planning strategies that can be deployed on a tax neutral basis.

Should all tax planning strategies fail, the VIEs could, as a matter of last resort, make a non-deductible transfer to our PRC subsidiaries for the amounts of the stranded cash in the VIEs. This would result in the double taxation of earnings: one at the VIE level (for non-deductible expenses) and one at the PRC subsidiary level (for presumptive earnings on the transfer). Such a transfer and the related tax burdens would reduce our after-tax income to approximately 3.1% of the pre-tax income. Our management is of the view that the likelihood that this scenario would happen is remote.

The following tables present the summary statements of operations for our Company’s VIEs and other entities for the periods presented.

Restrictions on Foreign Exchange and the Ability to Transfer Cash between Entities, Across Borders and to U.S. Investors

Sunlands Technology Group’s ability to pay dividends, if any, to its shareholders and ADS holders and to service any debt it may incur will depend upon dividends paid by our PRC subsidiaries. Under PRC laws and regulations, our PRC subsidiaries are subject to certain restrictions with respect to paying dividends or otherwise transferring any of their net assets offshore to Sunlands Technology Group. In particular, under the current effective PRC laws and regulations, dividends may be paid only out of distributable profits. Distributable profits are the net profit as determined under PRC GAAP, less any recovery of accumulated losses and appropriations to statutory and other reserves required to be made. Each of our PRC subsidiaries is required to set aside at least 10% of its after-tax profits each year, after making up previous years’ accumulated losses, if any,

to fund certain statutory reserve funds, until the aggregate amount of such a fund reaches 50% of its registered capital. As a result, our PRC subsidiaries may not have sufficient distributable profits to pay dividends to us in the near future.

Furthermore, if certain procedural requirements are satisfied, the payment of current account items, including profit distributions and trade and service related foreign exchange transactions, can be made in foreign currencies without prior approval from State Administration of Foreign Exchange, or the SAFE, or its local branches. However, where RMB is to be converted into foreign currency and remitted out of China to pay capital expenses, such as the repayment of loans denominated in foreign currencies, approval from or registration with competent government authorities or its authorized banks is required. The PRC government may take measures at its discretion from time to time to restrict access to foreign currencies for current account or capital account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign currencies to satisfy our foreign currency demands, we may not be able to pay dividends in foreign currencies to our offshore intermediary holding companies or ultimate parent company, and therefore, our shareholders or investors in our ADSs. Further, we cannot assure you that new regulations or policies will not be promulgated in the future, which may further restrict the remittance of RMB into or out of the PRC. We cannot assure you, in light of the restrictions in place, or any amendment to be made from time to time, that our current or future PRC subsidiaries will be able to satisfy their respective payment obligations that are denominated in foreign currencies, including the remittance of dividends outside of the PRC. If any of our subsidiaries incurs debt on its own behalf in the future, the instruments governing such debt may restrict its ability to pay dividends to Sunlands Technology Group. In addition, our PRC subsidiaries are required to make appropriations to certain statutory reserve funds, which are not distributable as cash dividends except in the event of a solvent liquidation of the companies.

For PRC and United States federal income tax consideration of an investment in the ADSs, see “Item 10. Additional Information—10.E. Taxation.”

The Holding Foreign Companies Accountable Act, or the HFCAA, was enacted on December 18, 2020. The HFCAA states if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspection by the PCAOB for three consecutive years beginning in 2021, the SEC shall prohibit our shares or ADSs from being traded on a national securities exchange or in the over-the-counter trading market in the United States. On December 16, 2021, PCAOB issued the HFCAA Determination Report, according to which our auditors are subject to the determinations. Our auditor, the independent registered public accounting firm that issues the audit report included elsewhere in this annual report, as an auditor of companies that are traded publicly in the United States and a firm registered with the PCAOB, is subject to laws in the United States pursuant to which the PCAOB conducts regular inspections to assess its compliance with the applicable professional standards. Since our auditor is located in China, a jurisdiction where the PCAOB has been unable to conduct inspections without the approval of the PRC authorities, our auditor is currently not inspected by the PCAOB. The delisting of the ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment. The PCAOB is currently unable to inspect our auditors in relation to their audit work performed for our financial statements and inability of the PCAOB to conduct inspections over our auditors deprives our investors with the benefits of such inspections. For the details of the risks associated with the enactment of the HFCAA, see “Risk Factors—Our ADSs may be delisted under the Holding Foreign Companies Accountable Act if the Public Company Accounting Oversight Board, or the PCAOB, is unable to inspect auditors who are located in China. The delisting of our ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment. Additionally, the inability of the PCAOB to conduct inspections deprives our investors with the benefits of such inspections.The recent enactment of the Holding Foreign Companies Accountable Act may result in de-listing of the ADSs. The delisting of our ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.”

We believe education should nurture and spread new ideas to enrich lives. High-quality education should be available to everyone. We all share a common aspiration to improve ourselves through education. Our mission is to transform education through technology and innovation, making learning experiences enjoyable and rewarding.

We are the leader in China’s online post-secondary and professional education. We have a deep understanding of the educational needs of our prospective students and offer solutions that help them achieve their goals. We offer various degree-and diploma-oriented post-secondary courses through our online platforms. In addition, we offer online professional courses and educational content, including various interest courses, to help students prepare for professional certification exams and attain professional skills.

Founded in 2003 as a traditional education company, we transitioned to an online education model in 2014. Our online education model enables our students to access our course and educational content offerings anywhere and anytime.

We have been successful in addressing the unmet demand of a large, growing market and served approximately 2,540,000 students across China since we transitioned to an online education model in 2014. The number of our students was 1,039,733, 1,130,650 and 1,104,630, respectively, in 2019, 2020 and 2021. For the same years, our new student enrollments were 363,013, 434,240 and 434,228, respectively.

We offer post-secondary and professional education through extensive courses and educational content offerings. As of December 31, 2021, we offered Self-taught Higher Education Examination, or STE, programs covering 17 majors, master's degree-oriented and other degree-or diploma-oriented post-secondary programs, and professional certification and skills programs.

We adopt a counseling-oriented sales and marketing approach that seeks to offer our education solutions to meet their needs based on their education background and goals. We provide professional assistance and counseling to help students make informed decisions that best suit their learning needs. In addition, our enrollment consultants also help them formulate effective study plans throughout their enrollments in our courses.

Our students can access our services either through PC or mobile applications. Our online platform cultivates a personalized, interactive learning environment by featuring a virtual learning community and a vast library of educational content offerings that adapt to the learning habits of our students.

We focus on cultivating an engaging community among students, teachers and mentors, improving educational content development capabilities, and developing proprietary IT infrastructure and systems. We encourage students to become more committed and engaged by creating an interactive learning environment that fosters their desire to learn and build confidence in learning. We provide our students with strong learning support through our dedicated mentors, powered by our proprietary IT systems and live streaming platform.

We offer a unique approach to education research and development that organizes subject content into Learning Outcome Trees, our proprietary knowledge management system. Our Learning Outcome Trees enable us to customize teaching notes for our teachers, and develop comprehensive course outlines and quiz banks to enhance the learning experience. Based on student feedback and the latest updates on exam policies, we further update our educational content in our Learning Outcome Trees to continually improve teaching quality.

We seek to hire experienced and passionate teachers who can make learning fun and interactive. We equip our faculty members not only with a comprehensive set of teaching methods but also advanced technologies and data insights to enable them to develop their professional skills and enhance our overall teaching quality.

We have strived to improve the breadth and depth of our offerings while enhancing our teaching quality and operating efficiency which is demonstrated in recognition and awards we have received and student results. In 2021, our students’ average pass rate for STE exam was 59.5%, while according to a report prepared by iResearch and commissioned by us, the average pass rates for STE exam achieved by self-taught students and students enrolled in private schools between 2012 and 2016 were 43.4% and 35.6%, respectively.

Our net revenues were RMB2,193.9 million, RMB2,203.8 million and RMB2,507.8 million (US$393.5 million) respectively, and our gross billings were RMB2,358.5million, RMB2,350.4 million and RMB1,970.0 million (US$309.1 million), respectively, in 2019, 2020 and 2021. We recorded net loss of RMB395.2 million and RMB431.0 million in 2019 and 2020, respectively, and net profit of RMB212.4 million (US$33.3 million) in 2021. Our deferred revenues were RMB3,228.8 million, RMB3,024.4 million and RMB2,348.2 million (US$368.5 million), respectively, as of December 31, 2019, 2020 and 2021.

We offer our online education services through our online and mobile platforms to adult students pursuing post-secondary and professional education. We deliver a diverse, comprehensive range of online courses in a live streaming format focused on fostering an interactive learning experience and community-oriented student support services. We also provide our students with a variety of proprietary educational content to help reinforce what is taught in classes and assess their learning outcomes.

We promote our services through a multi-channel strategy, including online and mobile advertising, to effectively convert sales leads into student enrollments.

Through our technology that connects students with faculty and employees, we gather and analyze data at each stage of our students’ interactions with us in real-time, allowing us to better understand our students’ learning needs and enabling us to continually improve the quality of our service.

We offer a wide range of online courses addressing various educational needs of adults in China.

Currently, our course offerings mainly cover two main components, namely (i) degree-or diploma-oriented post-secondary courses, and (ii) professional certification preparation and professional skills courses. The following table sets forth our net revenues, gross billings and new student enrollments attributable to each type of course offering.

As of December 31, 2021, our STE courses covered 17 majors, including Chinese language and literature, law, pre-school education, marketing, English, human resource management, business administration, business management, modern corporate governance, financial management, advertising, accounting,, administrative management, computer information management, finance, chain operation management and, visual communication and design. Our degree-or diploma-oriented post-secondary course offerings also include preparation courses for the entrance examinations of Master of Business Administration in China, or MBA programs offered by select universities in United States, Australia, Spain, Republic of Belarus, and Malaysia.

STE courses have historically accounted for the largest proportion of our net revenues, gross billings and new student enrollments. In 2019, 2020 and 2021, STE courses represented approximately 80.5%, 66.8% and 41.3%, respectively, of our net revenues, and approximately 75.1%, 53.1% and 18.4%, respectively, of our gross billings. In addition, STE courses represented approximately 75.4%, 46.2% and 19.8%, respectively, of our new student enrollments for the years ended December 31, 2019, 2020 and 2021. See also “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Business—We face risks associated with our reliance on our STE course offerings, including risks resulting from changes in government policies or requirements relating to STE exams.”

In 2021, we enlarged our footprint by promoting overseas higher education, supported by our expanding cooperation with foreign institutions. We also diversified our overseas post-graduate degree offerings including MBA, Education, Psychology and Human Resources Management to meet Chinese students’ growing demands for quality overseas higher education from Australia, Spain, Europe and the United States, especially as the COVID-19 pandemic restricted international travel.

Our professional certification preparation course offerings cover various industries and professions, including accounting, human resources, teaching and finance. Our professional skills courses are designed to give our students the skills, knowledge and abilities that are commonly required or otherwise helpful for a broad range of professions. We experienced increased demand for professional certification and skills programs in 2021. The employment market is becoming increasingly competitive due to industrial restructuring in the wake of the COVID-19 pandemic, motivating workers to enhance their career competitiveness through vocational education. As of December 31, 2021, our certification programs included a variety of preparation courses for professionals ranging from teachers, accountants and tour guides, as well as certifications for human resources professionals and public accountants. In addition, we also developed more general interest courses as we saw a surging trend in adults undertaking interest courses online, such as wealth management courses, voice acting courses, Mandarin courses and animation design courses. Our course portfolio’s solid foundation has enabled us to successfully grasp market opportunities and effectively scale up our offerings as we remain fully committed to giving our users as many options as possible.

In 2019, 2020 and 2021, our professional certification preparation and professional skills courses represented approximately 7.1%, 12.2% and 31.7%, respectively, of our net revenues, and approximately 6.9%, 19.9% and 46.0%, respectively, of our gross billings. In addition, our professional certification courses represented approximately 15.6%, 43.5% and 69.6%, respectively, of our new student enrollments in 2019, 2020 and 2021.

In addition to the course offerings discussed above, we also offer exam preparation “crash courses” for exam-taking students. Instead of covering a wide range of topics in a particular subject matter, these courses are meant to cover the most frequently tested areas in the exams and provide training on test-taking strategies and skills to help our students improve their performance in actual exams.

Our teachers deliver our courses in a live streaming format through our websites and our mobile application. We believe that we are one of the first to offer live streaming courses in China’s education industry.

Our live streaming course delivery format allows us to cost-effectively expand student enrollments and maintain high teaching quality. Live streaming also improves efficiency of instruction and enriches the learning experience in a number of ways:

We believe our live streaming format and our highly interactive learning experience makes our services highly attractive to students. In 2019, 2020 and 2021, our new student enrollments were 363,013, 434,240 and 434,228, respectively.

We strive to build a vibrant and highly interactive virtual community for our students and faculty to augment their learning and teaching experience. For example, we have a bulletin board forum, available through our website and mobile application that enables our students in real time to share their ideas and learning experience with, as well as pose questions and answers to fellow students and our faculty. This also provides a stimulating learning platform for our students to socialize and interact with an extended network of fellow students and faculty members and to forge beneficial relationships. In addition, our students can authorize his or her fellow students to view their learning progress and milestones, thus fostering an engaging and friendly competitive environment.

We believe a highly interactive virtual student community drives our existing students’ level of engagement and significantly enhances our attractiveness to prospective students.

Our classes are set up to cultivate an interactive learning environment. We are committed to developing a sense of community among our students and faculty, which we believe is critical to improving results.

Furthermore, our community-oriented learning environment, coupled with our student-centric faculty structure, enable us to provide our students attention and support beyond class hours at a time and in a manner that is convenient to them, which further drives student engagement, customer loyalty and course consumption.

Our class are set up by schools, divisions and classes. Students are assigned to different schools and divisions based on the major and number of students enrolled for a given academic period. Students in the same division are further assigned to different “classes” for administrative purposes.

We maintain an experienced team of course and educational content development professionals. Our course and educational content development team is dedicated to designing course offerings, as well as developing and improving a wide range of proprietary educational content, such as course outlines, quiz banks and teaching notes, for substantially all of our online course offerings.

We regularly upgrade our educational content to make it more practical, and easier to comprehend and apply in real exams. For instance, we regularly release major updates to our proprietary quiz banks and mock questions for students pursuing the STE exams to reflect updates in the test topics in the government-administered STE exams. Benefiting from our IT infrastructure, our course and educational content development team is able to view and analyze student performance in quiz banks and mock questions, which enables them to identify weaknesses in the educational content and make timely adjustments and upgrades accordingly. Our course and educational content development team also seeks feedbacks from teachers and students regarding the effectiveness of our educational content, through online questionnaires or in-person meetings.

In addition to our proprietary educational content, our course and educational content development professionals also design and recommend to our teachers’ best practices in teaching methods. While our teachers retain substantial control of and flexibility in the way their classes are taught, our course and educational content development professionals continually work closely with them to ensure our courses and educational content are delivered in an engaging, effective manner. We use Learning Outcome Trees to help us structure and deliver our educational content offerings, including course outlines, teaching notes and quiz banks, more effectively.

We support the learning experience with a wide range of educational content designed to help them capture key takeaways from, and reinforce what is taught in, our live streaming lessons, and to assess learning outcomes both during and after class hours. We also provide our teachers with educational content to help them prepare and teach classes effectively. All of our educational content was developed by our in-house research and development team and distributed electronically to our students and faculty through our online platforms.

We have a large student base, primarily as a result of our well-established brand and effective sales and marketing efforts. In 2019, 2020 and 2021, we had 1,039,733, 1,130,650 and 1,104,630 students, respectively, and our new student enrollments were 363,013, 434,240 and 434,228, respectively.

Our students are primarily working adults who generally have limited time to devote to lengthy and regular classroom studies at designated physical locations. Such students also need an engaging learning atmosphere that encourages participation and interaction, and require more assistance and supervision from their teachers and mentors.

Our target students generally have aspirations to obtain more knowledge, pursue higher education and improve their social and economic status. At the same time, many of them cannot identify their specific education needs or solutions for such needs, especially given that education products and services can be complex and the relatively high costs may deter them from fulfilling their educational needs. To help them meet their aspirations and understand the potential educational solutions, we focus our marketing and sales practices on counseling-oriented interactions and strive to deliver our courses and educational content in a highly engaging and student-friendly manner.

We maintain a large full-time faculty dedicated to helping our students succeed. As of December 31, 2021, our faculty primarily consisted of 113 teachers and 337 mentors based in Beijing, Guangzhou and Wuhan, China.

Our teachers and mentors assume different roles and responsibilities. Generally, our teachers are responsible for delivering courses and educational content to our students, while our mentors focus on providing academic and administrative support throughout the students’ learning process. We believe their different functions require different skills and personal attributes, and therefore we apply differentiated recruitment, training, and evaluation and compensation strategies to our teachers and mentors. For risks related to our faculty, see “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Business—We may not be able to continue to recruit, train and retain a sufficient number of qualified faculty members.”

We believe maintaining a high-quality team of teachers is the bedrock of our brand and reputation, particularly given our online course delivery model where each teacher is expected to cover a larger number of students than in offline, classroom-based courses. We monitor the total number of hours our teachers teach regularly to provide both an optimal number of teachers for our large student enrollments and adequate teaching assignments for each of our teachers. All of our teachers are our full-time employees. The training we provide to teachers is designed to allow teachers to develop their own teaching style and methodology while maintaining high teaching quality.

We hire our teachers based on numerous criteria, including educational backgrounds, teaching experience, and performance in mock lessons. We typically look for candidates with a bachelor’s degree from a top university or college in China or a master’s or higher degree. Additionally, given the interactive nature of our live streaming lessons, we look for teachers with strong communication skills, great passion for teaching and excellent ability of working under pressure.

We offer standard training programs to newly-hired teachers. We also impose a probation period and require each newly hired teacher to pass a number of internal qualification tests throughout the probation to be formally employed as full-time teachers. We also provide on-the-job training on instructional and communication skills to our teachers on a regular basis. Our proprietary IT system is key to our teacher training efforts as it not only allows them to monitor student engagement and academic performance on a real time basis but also to adjust teaching methodology and strategy accordingly to keep students engaged.

We have developed a fully-digital and systematic assessment approach that provides teachers with transparent and helpful feedback that serves as the foundation for their professional development and helps them to build fulfilling careers with us. We adopt a comprehensive set of key performance indicators, or metrics, to evaluate teacher performance. These metrics include student attendance rate and student satisfaction, among others. We also collect student reviews after each class and closely monitor the educational content delivered by our teachers to facilitate our teacher evaluation efforts and to improve our teaching quality. In addition, we use mock lessons to assess a teacher’s teaching skills and ability to engage students in a live streaming course setting, especially in instances where multiple teachers are competing to teach the same course.

We pay our teachers base salaries and service fees generally on a per-lesson basis. The service fees per lesson of a teacher are based primarily on his or her rating and other factors, such as student reviews and exam results. To incentivize our teachers, we also provide them with discretionary, merit-based bonuses based on their performance, measured by selected metrics. We enter into with each teacher a standard employment agreement typically for an initial term of three years which automatically renews at the end of each term.

Our mentors’ principal role is to provide academic guidance and support to our students on a daily basis to help navigate their way throughout the entire duration of studies. Our mentors’ roles and responsibilities typically include:

We tend to look for mentors who demonstrate excellent interpersonal and communication skills and a commitment in participating in the education profession and impacting a diverse audience. We typically require our mentors to possess a bachelor’s degree.

We provide our mentors with an orientation program and periodic on-the-job training to improve their ability to engage and build relationships with students. We also provide our mentors with training opportunities that address specific challenges. We have also introduced systems and tools that enable our teachers to monitor student activities and outcomes and take appropriate actions when the students demonstrate a low level of engagement.

We use various metrics in terms of student engagement to measure the performance of our mentors. These metrics include student’s class attendance, refund request rate, as well as the percentage of outperforming students. With each of our mentors we enter into a standard employment agreement typically for an initial term of three years which automatically renews at the end of each term.

Our marketing philosophy is to promote our services to prospective students in a cost-effective manner based on our deep understanding of their unique profile and needs. We have acquired many of our existing students through effective marketing campaigns focused on showing how our services can address their specific educational needs. At the same time, we market our services to a larger group of prospective students who are not aware of solutions available to satisfy their needs through tailored marketing efforts designed to awaken their potential demands and navigate them through their decision-making process.

For the years ended December 31, 2019, 2020 and 2021, our marketing effectiveness ratio, measured by dividing marketing spending by gross billings, was 40.2%, 46.9% and 41.6%, respectively.

We have built a large, well-trained professional sales and marketing team. As of December 31, 2021, we had a total of 3,001 sales and marketing personnel. We maintain sales and marketing personnel in major regional markets, such as Beijing, Wuhan, Shenzhen and Guangzhou. Our sales and marketing force adopt sales and marketing strategies customized based on the needs and profile of prospective students in different markets. We divide our sales and marketing personnel into different teams, each dedicated to executing our marketing strategies in a particular course offering or demographics.

We engage in a variety of advertising and marketing activities to build our brand and use a combination of online and offline channels.

We generate our leads primarily from online channels, which consist of search engine marketing and mobile marketing. Empowered by our data analytics capabilities, we use automated bidding strategies to place ads intelligently, as well as to track performance of our ads in real time, which enables us to generate more qualified clicks leading to our websites. We put ads on strategically chosen mobile applications that generate premium traffic quality to maximize our return of investment from mobile marketing channels.

Our search engine marketing channels effectively target students who possess preliminary interest in our services. We purchase key words from major search service providers in China, such as Baidu, and enhance returns from search engine marketing channels using search engine optimization techniques. We monitor end-to-end performance metrics of our search engine marketing channels on a continuous basis.

We also generate leads online through mobile marketing channels, which mainly include display advertising on leading mobile news apps, as well as social media platforms and online shopping platforms. The display advertising formats we use generally include launch screen display, banners, text hyperlinks, videos and rich media. We also operate branded official accounts on Weixin/WeChat, Sina Weibo, Tik Tok and other social media platforms to raise our brand awareness and increase sales leads generated on these platforms. We believe that our mobile marketing efforts are particularly effective in awakening potential demands of prospective students who have not yet developed a specific learning plan.

The terms of the agreements we enter into with our search engine and mobile marketing partners are typically one year. We pay our search engine and mobile marketing partners generally on a cost-per-click basis.

In addition to online advertising focused on mobile applications with high traffic volume, we engage in offline branding activities to a much lesser extent to supplement our overall sales and marketing strategies. Our offline branding activities primarily include public displays at major subway stations in Beijing, as well as establishment of 41 enrollment centers strategically located in our regional markets as of December 31, 2021. We believe that these cities represent the largest student base in China, and the primary goal of these advertisements is to enhance our presence in the local markets.

To convert leads generated into student enrollments, we provide customized, comprehensive counseling to prospective students throughout the lead nurturing and enrollment cycle. This counseling-oriented sales approach is supported by a capable sales team consisting of live chat personnel, call center staff and recruitment consultants based in our regional enrollment centers. We provide extensive training to our sales team to ensure they are capable of explaining our course offerings, addressing questions and concerns, and recommending courses that best suit prospective students’ learning objectives. We also use our data analytics tools and models to identify a prospective student’s educational needs, which helps our sales team provide tailor-made counseling services.

We use multi-layer lead-nurturing strategies to acquire new student enrollments in a cost-effective manner. Each of the leads generated are initially directed to our live chat support team who is responsible for answering prospective students’ enquires, encouraging them to register with our platforms, and collecting necessary information. Once a prospective student indicates an interest in purchasing our courses, we match such student with the most suitable sales professional based on our data analytics and tools. Such sales professional will follow up with the prospective student. In addition, we launch advertisements on various platforms, where we are able to obtain the contact information of our prospective students if they indicate interest in our courses. We then invite prospective students to join our online learning group and provide them with access to our trial courses. A prospective student that has signed up for our courses will be directed to our local enrollment centers to complete course purchase and registration with the assistance of our enrollment consultants. Our enrollment consultants are also responsible for providing counseling services to enrolling students and guiding them through the payment process. Our students can also choose to complete the purchase and enrollment process entirely online.

We devote significant resources to maintaining a reliable, scalable and secure IT infrastructure. We have built our integrated IT infrastructure primarily based on tools, technologies and platforms that we have developed in-house and, to a lesser extent, third-party software and applications that we have licensed or purchased.

We maintain a dedicated IT development and support team. As of December 31, 2021, we had 231 technology development personnel.

Our IT infrastructure is critical to supporting our pursuit of excellent student experience and optimal operating efficiency. We have developed Genesis, our proprietary integrated IT infrastructure, to support and connect our students and employees during every major aspect of our business operations, encompassing marketing, sales, course delivery and development, and operation management.

Powering various services and functions, including information and data transmission and sharing, centralized data tracking and data analytics, Genesis is composed of both student interface and employee interface. For one thing, the student interface supports applications and platforms that enable our students to enroll in courses, attend classes, access educational content, interact within our virtual community, and engage in other learning activities throughout their service periods; for another thing, Genesis also incorporates different subsets of functions used by our employees, ranging from our teachers and mentors to our marketing and sales personnel. The employee interface is specifically customized to provide our employees with information and data most relevant to their responsibilities. In addition, Genesis supports a centralized database allowing its users, including our students and employees, to contribute, share and store content and data across our various applications and platforms.

We launched our AI-powered personalized study programs in 2018. This AI-powered software, developed in-house, uses machine learning and natural language processing technology to analyze student behavior and their level of understanding of specific courses. Based on this analysis, we are able to predict test results, with a high accuracy rate, and develop tailor-made learning solutions that are designed to improve study outcomes.

We are one of the first movers in China’s education sector to deliver interactive education services via mobile platforms, which has enabled students to learn and connect with fellow students and faculty in a more efficient and flexible manner. Our Sunlands mobile app, available on both iOS and Android, is built with a clear and functional interface that enables access to our course and educational content offerings and our virtual learning community. We have also built mobile WAP pages which allow our students and faculty to enjoy a similar level of functionality as our mobile app without installation.

Our tuition fees, including academic fees and registration fees, are charged generally on a per-program basis. From time to time, we offer tuition discounts under various marketing campaigns and promotions. For example, discounts may also be made available to students who purchase multiple courses at a time. We accept fee payments through major third-party online payment solutions in China, including Alipay, Union Pay and WeChat Pay, as well as bank transfers and credit cards.

Students typically self-finance their education or obtain financing from third-party financing programs that cooperate with us. We currently offer the following two payment options to our students:

We generally offer students a full, unconditional refund within 24 hours upon enrollment. If a student requests a refund after taking at least one live streaming course lasting 30 minutes due to any material academic issue associated with our courses within certain refund period, we offer a refund excluding the registration fees and the fees of delivered courses upon our confirmation. In addition, we offer students a refund for the undelivered courses excluding the registration fees. Prior to June 2019, such refund was provided only within seven days upon enrollment while starting from June 2019, we offer such refund during the entire service period. When calculating gross billings for a specific period, we deduct the total amount of refunds from the total amount of cash received for the sale of course packages for such period.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We own copyrights to the educational content we developed in-house. We enter into standard employment agreements with our teachers, course development staff and other employees which provide that the intellectual property created by them in connection with their employment with us is our intellectual property. As of the date of this annual report, we have registered 117 trademarks with the Trademark Office of the PRC State Administration of Industry and Commerce, registered 109 software copyrights with the PRC State Copyright Bureau, and registered 250 domain names.

Despite our efforts to protect ourselves from infringement or misappropriation of our intellectual property rights, unauthorized parties may attempt to copy or otherwise obtain and use our intellectual property. In the event of a successful claim of infringement and our failure or inability to develop non-infringing intellectual property or license the infringed or similar intellectual property on a timely basis, our business could be harmed. See “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Business—We may from time to time be subject to infringement claims relating to intellectual properties of third parties.” and “—If we fail to protect our intellectual property rights, our brand and business may suffer.”

We primarily compete with offline, classroom-based education service providers. Additionally, we expect to face competition as a result of new entrants to the postsecondary and professional education market in China, including established education service providers that had not previously offered online education courses. We compete with our competitors for student enrollments and engagement, high-quality faculty members, sales and marketing effectiveness, among other things.

We believe that the principal competitive factors in China’s post-secondary and professional education market include the following:

We believe we compete favorably on the basis of these factors. Our ability to remain competitive will depend, to a great extent, upon our ability to consistently deliver high-quality course offerings and acquire, support and retain students. Some of our present and future competitors may have longer operating histories, larger teams of teaching faculty and supporting staff and greater financial, technical, marketing and other resources. For a discussion of risks relating to competition, see “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Business—We face intense competition in our industry, which could divert student to our competitors, lead to pricing pressure and loss of market share, and significantly reduce our gross billings and net revenues.”

We believe data security is critical to our business operation because data is the foundation of our competitive advantages. We have internal rules and policy to govern how we may use and share personal information, as well as protocols, technologies and systems in place to ensure that such information will not be accessed or disclosed improperly. Users must acknowledge the terms and conditions of the user agreement before using our products, under which they consent to our collection, use and disclosure of their data in compliance with applicable laws and regulations.

From an internal policy perspective, we limit access to our servers that store our user and internal data on a “need-to-know” basis. We also adopt a data encryption system intended to ensure the secured storage and transmission of data, and prevent any unauthorized member of the public or third parties from accessing or using our data in any unauthorized manner. Furthermore, we implement comprehensive data masking of user data for the purpose of fending off potential hacking or security attacks.

We do not maintain any liability insurance or property insurance policies covering students, equipment and facilities for injuries, death or losses due to fire, earthquake, flood or any other disaster. Consistent with customary industry practice in China, we do not maintain business interruption insurance, nor do we maintain key-man life insurance.

Our PRC subsidiaries and the VIEs have obtained all material licenses and approvals required for our operations in China, excepts as disclosed in “Item 3. Key Information—3.D. Risk Factors—Risk Related to Our Business—We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.”, “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business—We face regulatory risks and uncertainties with respect to the licensing requirement for the online transmission of internet audio-visual programs.” and “Item 3. Key Information—3.D. Risk Factors—Risk Related to Our Business—Our failure to obtain and maintain other approvals, licenses, permits or filings applicable to our business could have a material adverse impact on our business, financial conditions and results of operations” For risks relating to licenses and approvals required for our operations in China, see “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business and Industry.”

The following table sets forth a list of material licenses and approvals, subject to further renewal, that our PRC subsidiaries and VIEs are required to obtain and have obtained to carry out our operations in China.

According to the latest Special Administrative Measures for the Entry of Investment (Negative List), or the Negative List, promulgated by the Ministry of Commerce, or MOFCOM and the National Development and Reform Commission, or NDRC, effective on January 1, 2022, foreign investors shall not engage in the prohibited activities listed in the Negative List. Pursuant to the latest Negative List, the provision of value-added telecommunications services falls in the category of restricted activities and, with a few exceptions, the percentage of foreign ownership cannot exceed 50% (except for e-commerce, domestic multi-party communication, store-and-forward and call center).

The latest negative list further provides that domestic companies engaged in foreign investment prohibited business and intend to offer and list securities in overseas markets shall obtain approval from relevant government authorities.

On March 15, 2019, the Standing Committee of the National People’s Congress published the Foreign Investment Law, or the FIL, which became effective on January 1, 2020. The FIL is expected to replace the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The existing foreign-invested enterprises established prior to the effective of the FIL may keep their corporate forms within five years. Pursuant to the FIL, “foreign investors” means natural person, enterprise, or other organization of a foreign country, “foreign-invested enterprises” (FIEs) means any enterprise established under PRC law that is wholly or partially invested by foreign investors and “foreign investment” means any foreign investor’s direct or indirect investment in mainland China, including: (i) establishing FIEs in mainland China either individually or jointly with other investors; (ii) obtaining stock shares, stock equity, property shares, other similar interests in Chinese domestic enterprises; (iii) investing in new projects in mainland China either individually or jointly with other investors; and (iv) making investment through other means provided by laws, administrative regulations, or State Council provisions.

The FIL stipulates that China implements the management system of pre-establishment national treatment plus a negative list to foreign investment and the government generally will not expropriate foreign investment, except under special circumstances, in which case it will provide fair and reasonable compensation to foreign investors. Foreign investors are barred from investing in prohibited industries on the negative list and must comply with the specified requirements when investing in restricted industries on that list. When a license is required to enter a certain industry, the foreign investor must apply for one, and the government must treat the application the same as one by a domestic enterprise, except where laws or regulations provide otherwise. In addition, foreign investors or FIEs are required to file information reports and foreign investment shall be subject to the national security review.

On December 26, 2019, the Supreme People’s Court of the PRC promulgated the Interpretation of the Supreme People’s Court on Several Issues Concerning the Application of the Foreign Investment Law of the PRC, effective as of January 1, 2020, pursuant to which “investment contracts” shall mean the relevant agreements formed as a result of direct or indirect investments in the PRC by foreign investors, i.e. foreign natural persons, foreign enterprises or other foreign organizations, including contracts for establishment of foreign investment enterprises, share transfer contracts, equity transfer contracts, contracts for transfer of property or other similar interests, contracts for newly-built projects, etc. Where a party concerned claims that an investment contract is invalid for investing in prohibited industries as stipulated in the Negative List for foreign investment access or due to violation of specified administrative measures in restricted industries, the People’s Court shall support such claim.

On December 26, 2019, the State Council published the Implementation Rules of Foreign Investment Law, which came into effect on January 1, 2020. The Implementation Rules of Foreign Investment Law restates certain principles of the FIL and further provides, among others, (i) an FIE’s investment within the territory of PRC is also subject to the FIL and the Implementation Rules of Foreign Investment Law; (ii) an FIE may, within five years following January 1, 2020, choose to amend its legal form or the corporate governance and complete amendment registration, or to keep its original legal form or the corporate governance; (iii) the provisions regarding the transfer of equity interests, distribution of profits and remaining assets as stipulated in the contracts among the joint venture parties of an existing FIE may survive the FIL after such FIE amends its legal form or the corporate governance in accordance with relevant applicable laws.

On December 19, 2020, the NDRC and the MOFCOM jointly promulgated the Measures on the Security Review of Foreign Investment, effective on January 18, 2021, which sets forth provisions concerning the security review mechanism on foreign investment, including the types of investments subject to review, review scopes and procedures, among others. The Office of the Working Mechanism of the Security Review of Foreign Investment, or the Office of the Working Mechanism will be established under the NDRC, who will carry out routine work of security review on foreign investment. Foreign investor or relevant parties in China must declare the security review to the Office of the Working Mechanism prior to (i) the investments in the military industry, military industrial supporting and other fields relating to the security of national defense, and investments in areas surrounding military facilities and military industry facilities; and (ii) investments in important agricultural products, important energy and resources, important equipment manufacturing, important infrastructure, important transport services, important cultural products and services, important information technology and internet products and services, important financial services, key technologies and other important fields relating to national security, and obtain control in the target enterprise. Control exists when the foreign investor (i) holds over 50% equity interests in the target, (ii) has voting rights that can materially impact on the resolutions of the board of directors or shareholders meeting of the target even when it holds less than 50% equity interests in the target, or (iii) has material impact on target’s business decisions, human resources, accounting and technology, etc.

On December 30, 2019, MOFCOM and the SAMR, jointly issued the Measures for Reporting of Foreign Investment Information, which came into effect on January 1, 2020. Since January 1, 2020, for foreign investors carrying out investment activities directly or indirectly in the PRC, foreign investors or foreign-invested enterprises shall submit investment information through certain system operated by SAMR. Foreign investors or foreign-invested enterprises shall disclose their investment information by submitting reports for their establishments, modifications and cancellations and their annual reports. If a foreign-invested enterprise investing in the PRC has finished submitting its reports for its establishment, modifications and cancellation and its annual reports, the relevant information will be shared by the competent market regulation department to the competent commercial department, and does not require such foreign-invested enterprise to submit the reports separately.

The PRC Regulations on Telecommunications, or the Telecommunications Regulations, which was latest amended and came into effect on February 6, 2016, regulate telecommunications activities in China. The Telecommunications Regulations divide the telecommunications services into two categories, namely “infrastructure telecommunications services” and “value-added telecommunications services.” Pursuant to the Telecommunications Regulations, operators of value-added telecommunications services must first obtain a Value-added Telecommunications Business Operating License, or VAT License, from the Ministry of Industry and Information Technology, or MIIT, or its provincial level counterparts. On July 3, 2017, the MIIT promulgated the Administrative Measures on Telecommunications Business Operating Licenses, which set forth more specific provisions regarding the types of licenses required to operate value-added telecommunications services, the qualifications and procedures for obtaining such licenses and the administration and supervision of such licenses.

According to the Catalog of Classification of Telecommunication Businesses, or the 2016 MIIT Catalog, which published by MIIT on December 28, 2015 and took effect on March 1, 2016 and were amended on June 6, 2019, internet information services, which include information release and delivery services, information search and query services, information community platform services, information real-times interactive services, and information protection and processing services, are classified as a category of value-added telecommunication services. The Administrative Measures on Internet Information Services, or ICP Measures, also promulgated by the PRC State Council on September 25, 2000 and most recently amended on January 8, 2011, set forth more specific rules on the provision of ICP services. According to ICP Measures, any company that engages in the provision of commercial ICP services shall obtain a sub-category VAT License for Internet Information Services, or ICP License, from the relevant government authorities before providing any commercial internet content services within the PRC, and when the ICP services involve areas of news, publication, education, medical treatment, health, pharmaceuticals and medical equipment, and if required by law or relevant regulations, specific approval from the respective regulatory authorities must be obtained prior to applying for the ICP License from the MIIT or its provincial level counterpart. Pursuant to the above-mentioned regulations, “commercial ICP services” generally refers to provision of specific information content, online advertising, web page construction and other online application services through internet for profit making purpose. Operating our online platform to provide information and services to our students is classified as commercial ICP services.

In addition to the Telecommunications Regulations and the other regulations set forth above, the provision of commercial internet information services on mobile internet apps is regulated by the Administrative Provisions on Mobile Internet Applications Information Services, which was promulgated by the Cyberspace Administration of China, or the CAC, on June 28, 2016 and came into effect on August 1, 2016. The providers of mobile internet applications are subject to requirements under these provisions, including acquiring the qualifications and complying with other requirements provided by laws and regulations and being responsible for information security. We currently, through Beijing Sunlands, our PRC consolidated VIE, and its wholly owned subsidiary, Beijing Shangren Chongye Education Technology Co., Ltd., or Shangren Chongye, respectively, hold an ICP License. The ICP License of Beijing Sunlands is valid until July 2, 2024 and the ICP License of Shangren Chongye, is valid until April 2, 2025.

The Regulations on Administration of Foreign-Invested Telecommunications Enterprises, or the FITE Regulations, which took effect on January 1, 2002 and latest amended on March 29, 2022, are the key regulations that regulate foreign direct investment in telecommunications companies in China. The FITE Regulations stipulate that, except as otherwise provided by relevant laws and regulations, the foreign investor of a telecommunications enterprise is prohibited from holding more than 50% of the equity interest in a foreign-invested enterprise that provides value-added telecommunications services.

On July 13, 2006, the MIIT issued the Circular on Strengthening the Administration of Foreign Investment in Value-added Telecommunications Services, or the MIIT Circular 2006, which requires that (i) foreign investors can only operate a telecommunications business in China through establishing a telecommunications enterprise with a valid telecommunications business operation license; (ii) domestic license holders are prohibited from leasing, transferring or selling telecommunications business operation licenses to foreign investors in any form, or providing any resource, sites or facilities to foreign investors to facilitate the unlicensed operation of telecommunications business in China; (iii) value-added telecommunications services providers or their shareholders must directly own the domain names and registered trademarks they use in their daily operations; (iv) each value-added telecommunications services provider must have the necessary facilities for its approved business operations and maintain such facilities in the geographic regions covered by its license; and all value-added telecommunications services providers should improve network and information security, enact relevant information safety administration regulations and set up emergency plans to ensure network and information safety. The

provincial communications administration bureaus, as local authorities in charge of regulating telecommunications services, (i) are required to ensure that existing qualified value-added telecommunications service providers will conduct a self-assessment of their compliance with the MIIT Circular 2006 and submit status reports to the MIIT before November 1, 2006; and (ii) may revoke the value-added telecommunications business operation licenses of those that fail to comply with the above requirements or fail to rectify such noncompliance within specified time limits. Due to the lack of any additional interpretation from the regulatory authorities, it remains unclear what impact MIIT Circular 2006 will have on us or the other PRC internet companies with similar corporate and contractual structures. After the MOFCOM and NDRC amended the Catalog in March 2015, MIIT also issued the Circular on Removing the Restrictions on Shareholding Ratio Held by Foreign Investors in Online Data Processing and Transaction Processing (Operating E-commerce) Business on June 19, 2015, which amended the relevant provision in FITE Regulations by allowing foreign investors to own more than 50% of the equity interest in an operator of e-commerce business. However, foreign investors continue to be prohibited from holding more than 50% of the equity interest in a provider of other categories of value-added telecommunications services except for e-commerce, domestic multi-party communication, store-and-forward, and call center.

To comply with the above-mentioned foreign ownership restrictions, we operate our online platform in China through Beijing Sunlands and its wholly owned subsidiary, Shangren Chongye, all of the shareholders of Beijing Sunlands are PRC domestically funded entities, and Beijing Sunlands is controlled by Wuhan Zhibo, our PRC subsidiary, through a series of contractual arrangements. Beijing Sunlands and Shangren Chongye are the holders of the domain names, trademarks and facilities necessary for daily operations of our online platforms in compliance with the MIIT Circular 2006. Based on our PRC legal counsel’s understanding of the current PRC law, rules and regulations, the contractual arrangements among Wuhan Zhibo, Beijing Sunlands and its shareholders and subsidiaries are valid, binding and enforceable under current PRC law. However, we were further advised by our PRC legal counsel that there are substantial uncertainties with respect to the interpretation and application of existing or future PRC laws and regulations and thus there is no assurance that Chinese governmental authorities would take a view consistent with the opinions of our PRC legal counsel.

On March 18, 1995, the PRC National People’s Congress promulgated the Education Law of the PRC, or the Education Law, which was further amended on August 27, 2009, on December 29, 2018 and on April 29, 2021, stipulates that the government formulates plans for the development of education, establishes and operates schools and other types of educational institutions, and in principle, enterprises, institutions, social organizations and individuals are encouraged to operate schools and other types of educational organizations. Comparing to the version of Education Laws that was amended and came into effect on 2009, which provided that no organization or individual may establish or operate a school or any other educational institution for commercial purposes, the current Education Law narrowed the provision prohibiting the establishment or operation of schools or other educational institutions for commercial purposes to only restricting a school or other educational institution founded with governmental funds or donated assets in the amended Education Law.

On April 20, 2022, Standing Committee of the National People’s Congress, or the SCNPC, adopted the amended Vocational Education Law of the PRC, or the Amended Vocational Education Law, which will become effective on May 1, 2022 and replace the previous Vocational Education Law of the PRC adopted in 1996. The Amended Vocational Education Law specifies that the vocational education is as important as regular education and that the state encourages the development of various levels and forms of vocational education, the extensive and equal participation of social forces in vocational education and the international communication and the cooperation in vocational education, and strives to improve vocational education recognition. The Amended Vocational Education Law also provides the establishment and improvement of the vocational education system, deepening cooperation between enterprises and schools, and the improvement of the vocational education guarantee system and measures.

The Law for Promoting Private Education of the PRC became effective on September 1, 2003 and was last amended on December 29, 2018, and the Implementation Rules for the Law for Promoting Private Education, or PE Implementation Rules of the PRC became effective on April 1, 2004.

The Decision of the Standing Committee of the National People’s Congress on Amending the Law for Promoting Private Education of the PRC, or the Amendment, has been promulgated by Order No. 55 of the President of the PRC on November 7, 2016 and came into force on September 1, 2017.

Under the Amendment, sponsors of private schools may choose to establish non-profit or for-profit private schools at their own discretion. Nonetheless, school sponsors are not allowed to establish for-profit private schools that are engaged in compulsory education. In other words, the schools engaged in compulsory education should retain their non-profit status after the Amendment comes into force. The Amendment further establishes a new classification system for private schools to be classified by whether they are established and operated for profit-making purposes.

On April 7, 2021, the State Council published the amendment to the Regulations on the Implementation of the Law for Promoting Private Education of the PRC, or Amended Implementing Rules, which became effective on September 1, 2021. The Amended Implementing Rules stipulates that online education activities using internet technology are encouraged by the regulatory authorities and shall comply with laws and regulations related to internet management. A private school using internet technology to conduct education activities shall obtain an appropriate private school operating permit and shall establish and implement internet security management systems and take technical security measures. Upon discovery of any information whose release or transmission is prohibited by applicable laws or regulations, the private school shall immediately cease the transmission of that information and take further remedial actions, such as deleting that information, to prevent it from spreading. Records pertaining to the situation shall be kept and reported to the appropriate authorities.The Amended Implementing Rules further stipulates that any entities or individuals shall not control any schools providing compulsory education or any non-profit schools providing pre-school education through merger, acquisition or contractual arrangements. A private school providing compulsory education shall not conduct any transaction with any related party. Any other private school conducting any transaction with any related party shall follow the principles of openness, fairness and impartiality, fix the price reasonably and regulate the decision-making, and shall not damage the state interests, the interests of the school or the rights and interests of the teachers and students. A private school shall establish an information disclosure system for related party transactions and relevant government authorities shall enhance the supervision on the agreements entered into between non-profit private schools and its related party and shall review such transactions on an annual basis.

On December 29, 2016, the State Council issued the Several Opinions of the State Council on Encouraging the Operation of Education by Social Forces and Promoting the Healthy Development of Private Education, or the State Council Opinions, which requires to ease the access to the operation of private schools and encourages social forces to enter the education industry. The State Council Opinions also provides that each level of the people’s governments shall increase their support to the private schools in terms of financial investment, financial support, autonomy policies, preferential tax treatments, land policies, fee policies, autonomy operation, protecting the rights of teachers and students etc. Further, the State Council Opinions require each level of the people’s governments to improve its local policies on government support to for-profit and non-profit private schools by ways of preferential tax treatments etc. In addition, under the State Council Opinions, private schools shall strengthen its construction of the Chinese Communist Party, or the CCP, and further the theoretical system of Socialism with Chinese Characteristics by introducing such system into textbooks and teaching programs. The construction of the CCP’s organizations by the private schools as well as the CCP’s leadership to private schools shall constitute an important part of such schools’ annual inspection.

On December 30, 2016, the MOE, Ministry of Civil Affairs, State Administration for Industry and Commerce (the predecessor of the State Administration for Market Regulation), the Ministry of Human Resources and Social Welfare and the State Commission Office of Public Sectors Reform jointly issued the Implementation Rules on the Classification Registration of Private Schools to reflect the new classification system for private schools as set out in the Amendment. Generally, if a private school established before promulgation of the Amendment chooses to register as a non-profit school, it shall amend its articles of association, continue its operation and complete the new registration process. If such private school chooses to register as a for-profit school, it shall conduct financial liquidation process, have the property rights of its assets such as lands, school buildings and net balance being authenticated by relevant government authorities, pay up relevant taxes, apply for a new private school operating permit, re-register as for-profit school and continue its operation. Specific provisions regarding the above registrations are yet to be introduced by people’s governments at the provincial level.

On December 30, 2016, the MOE, State Administration for Industry and Commerce and the Ministry of Human Resources and Social Welfare jointly issued the Implementation Rules on the Supervision and Administration of For-profit Private Schools, pursuant to which the establishment, division, merger and other material changes of a for-profit private school shall first be approved by the education authorities or the authorities in charge of labor and social welfare, and then be registered with the competent branch of State Administration for Industry and Commerce. In addition, it also provides that for-profit private training institutes shall be analogically governed by these Implementation Rules on the Supervision and Administration of For-profit Private Schools.

On July 24, 2021, the General Office of State Council and the General Office of Central Committee of the Communist Party of China jointly promulgated the Opinions on Further Alleviating the Burden of Homework and After-School Tutoring for Students in Compulsory Education, or the Alleviating Burden Opinion, which mainly aims to alleviate the burden of

excessive homework and the burden of after-school training on students in the compulsory education stage and sets out a series of operating requirements on after-school tutoring institutions.

Uncertainties exist with respect to the interpretation and application of the existing and future laws and regulations governing online private education industry, as well as how the local government would promulgate implementing rules relating to the specific requirements applicable to online education service providers like us. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business—We face risks associated with our lack of a private school operating permit for our online education services as well as uncertainties surrounding PRC laws and regulations governing the education industry in general, including the Law for Promoting Private Education and its Implementation Rules.”

The MOE, jointly with certain other PRC government authorities, promulgated the Opinions on Guiding and Regulating the Orderly and Healthy Development of Educational Mobile Apps on August 10, 2019, or the Opinions on Educational Apps, which requires, among others, mobile apps that provide services for school teaching and management, student learning and student life, or home-school interactions, with school faculty, students or parents as the main users, and with education or learning as the main application scenarios, or the Educational Apps, be filed with competent provincial regulatory authorities for education before the end of 2019. The Opinions on Educational Apps also requires, among others, that before filing, the Educational App’s provider obtain the ICP License or complete the ICP filing and obtain the certificate and the grade evaluation report for graded protection of cybersecurity. On November 11, 2019, MOE issued the Administrative Measures on Filing of Educational Mobile Apps, which requires, among others, that educational mobile app providers shall file their educational mobile apps and that filings of existing educational mobile apps shall be completed before January 31, 2020. If the filing requirements are violated and not rectified in a timely manner, the MOE or its local counterparts may revoke the filing of such educational mobile app, blacklist such provider, report such provider to the education system, and prohibit such provider from submitting any filings for six months. The MOE established a public channel that can be used to submit complaints with respect to educational apps and set a penalty points system based on the severity of the complaints. For serious complaints substantiated by relevant government authorities, an appropriate number of penalty points is recorded for the relevant educational app provider, and remedial measures also may be required. In the event that an educational app provider receives 12 or more penalty points within 12 months or certain types of serious complaints, the MOE may revoke such provider’s filing, blacklist such provider, remove its educational app from the app store, publicize the complaint or prohibit such provider from submitting any filings for six months. Complaints can be made against both educational app providers and users regarding a variety of matters including failure to file or obtain relevant permits; illegal or inappropriate information; inappropriate collection and use of personal information; and violation of relevant requirements for primary and secondary schools and online after-school training programs.

On February 17, 2011, the Ministry of Culture, or MOC, promulgated the Interim Administrative Provisions on Internet Culture, or the Internet Culture Provisions, which became effective on April 1, 2011 and was further amended on December 15, 2017. The Internet Culture Provisions require ICP services providers engaging in commercial “internet culture activities” to obtain an Internet Culture Business Operating License from the MOC. “Internet cultural activities” is defined in the Internet Culture Provisions as an act of provision of internet cultural products and related services, which includes (i) the production, duplication, importation, and broadcasting of the internet cultural products; (ii) the online dissemination whereby cultural products are posted on the internet or transmitted via the internet to end-users, such as computers, fixed-line telephones, mobile phones, television sets and games machines, for online users’ browsing, use or downloading; and (iii) the exhibition and comparison of the internet cultural products. In addition, “internet cultural products” is defined in the Internet Culture Provisions as cultural products produced, broadcast and disseminated via the Internet, which mainly include internet cultural products specially produced for the Internet, such as online music entertainment, online games, online shows and plays (programs), online performances, online works of art and online cartoons, and internet cultural products produced from cultural products such as music entertainment, games, shows and plays (programs), performances, works of art, and cartoons through certain techniques and duplicating those to internet for dissemination.

On May 14, 2019, the General Office of MOC promulgated the Notice on Adjusting the Scope of Internet Culture Business Operating License and Further Standardize the Approval Work, which provides that online music, online shows and plays, online performances, online works of art, online cartoons, displays and games are the activities that fall in the scope of internet culture business operating license, and further clarifies that educational live streaming activities are not deemed as online performances. Nevertheless, it remains unclear whether the local PRC government authorities would adopt a different practice. In addition, it remains uncertain whether the PRC government authorities would issue more explicit interpretation and rules or promulgate new laws and regulations.

On June 27, 2002, the General Administration of Press and Publication (predecessor of the State Administration of Press, Publication, Radio, Film and Television, or the SAPPRFT) and the MIIT jointly promulgated the Tentative Internet Publishing Administrative Measures, or the Internet Publishing Measures, which took effect on August 1, 2002. The Internet Publishing Measures require entities that engage in Internet publishing to obtain an Internet Publishing License for engaging in Internet publishing from the SAPPRFT. Pursuant to the Internet Publishing Measures, the definition of “Internet publishing” is broad and refers to the act by ICP services providers to select, edit and process works created by themselves or others and subsequently post such works on the internet or transmit such works to the users’ end through internet for the public to browse. The “works” as defined under the Internet Publishing Measures include (i) contents from books, newspapers, periodicals, audio-visual products, electronic publications that have already been formally published or works that have been made public in other media, and (ii) all other edited or processed works of literatures, art, natural science, social science, engineering technology, etc.

On February 4, 2016, the SAPPRFT (currently reformed into the State Administration of Press and Publication (National Copyright Bureau) under the Propaganda Department of the Central Committee of the Communist Party of China) and the MIIT jointly issued the Administrative Provisions on Online Publishing Services, or the Online Publishing Provisions. The Online Publishing Provisions, taking effect as of March 10, 2016, superseded the Internet Publishing Measures. Compared with the Internet Publishing Measures, the Online Publishing Provisions set out more detailed provisions for online publishing activities, which mainly cover issues such as defining online publishing services, licensing and approvals, the administrative and supervisory regime and legal liabilities. According to the Online Publishing Provisions, all online publishing services provided within the territory of China are subject to the Online Publishing Provisions, and an Internet Publishing License shall be obtained to provide online publishing services. Pursuant to the Online Publishing Provisions, “online publishing services” refer to providing online publications to the public through information networks; and “online publications” refer to digital works with publishing features such as having been edited, produced or processed and are made available to the public through information networks, including: (i) written works, pictures, maps, games, cartoons, audio/video reading materials and other original digital works containing useful knowledge or ideas in the field of literature, art, science or other fields; (ii) digital works of which the content is identical to that of any published book, newspaper, periodical, audio/video product, electronic publication or the like; (iii) network literature databases or other digital works, derived from any of the aforesaid works by selection, arrangement, collection or other means; and (iv) other types of digital works as may be determined by the SAPPRFT. As the scope of online publication is broad, certain contents we post on our website, such as video-audio clips and course materials, may be deemed as online publications. Nevertheless, it remains unclear whether the local PRC government authorities would adopt a different practice. In addition, it remains uncertain whether the PRC government authorities would issue more explicit interpretation and rules or promulgate new laws and regulations.

Television program productions and distribution businesses are mainly regulated by Regulations on Administration of Radio and Television, which came in to effect on August 11, 1997 and was recently amended on November 11, 2020, and the Administrative Regulations on Production and Operation of Radio and Television Program which came into effect on August 20, 2004 and was last amended on October 29, 2020. Pursuant to these regulations, television programs can only be produced by television stations at the municipal level or above or entities with a License for the Production and Operation of Radio and Television Program. Any entity producing and operating radio and television program without the License for the Production and Operation of Radio and Television Program will be subject to the confiscation of tools, equipment of producing radio and television program and a fine of more than 10 thousand RMB and less than 50 thousand RMB by competent local branch of SAPPRFT.

Under the Administrative Measures for the Publication Market, or Publication Market Measures, which was jointly promulgated by the SAPPRFT and the MOFCOM on May 31, 2016 and became effective on June 1, 2016, any enterprise or individual who engages in publication distribution activities shall obtain permission from SAPPRFT or its local counterpart. “Publication” is defined as “books, newspapers, periodicals, audio-visual products, and electronic publications,” and “distributing” is defined as “general distribution, wholesale, retail, rental, exhibition and other activities,” respectively, in the Publication Market Measures. Any enterprise or individual that engages in retail of publications shall obtain a Publication Business Operating License issued by the local counterpart of SAPPRFT at the county level. In addition, any enterprise or individual that holds a Publication Business Operating License shall file with the relevant local counterpart of SAPPRFT that granted such license to it within 15 days since it begins to carry out any online publication distribution business.

The Measures for the Administration of Publication of Audio-Visual Programs through Internet or Other Information Network, or the Audio-Visual Measures, promulgated by the SAPPRFT, on July 6, 2004 and put into effect on October 11, 2004, apply to the activities relating to the opening, broadcasting, integration, transmission or download of audio-visual programs using internet or other information network. Under the Audio-Visual Measures, to engage in the business of transmitting audio-visual programs, a license issued by SAPPRFT is required, and “audio-visual programs (including audio-visual products of films and televisions)” is defined as the audio-visual programs consisting of movable pictures or sounds that can be listened to continuously, which are shot and recorded using video cameras, vidicons, recorders and other audio-visual equipment for producing programs. Foreign invested enterprises are not allowed to carry out such business. On April 13, 2005, the State Council promulgated the Certain Decisions on the Entry of the Non-state-owned Capital into the Cultural Industry. On July 6, 2005, five PRC governmental authorities, including the SAPPRFT, jointly adopted the Several Opinions on Canvassing Foreign Investment into the Cultural Sector. According to these regulations, non-state-owned capital and foreign investors are not allowed to engage in the business of transmitting audio-visual programs through information networks. However, the Audio-Visual Measures was repealed according to the Administrative Provisions on Audio-Visual Program Service through Special Network and Directed Transmission that was promulgated by the SAPPRFT on May 4, 2016, effective as of June 1, 2016.

To further regulate the provision of audio-visual program services to the public via the internet, including through mobile networks, within the territory of the PRC, the SAPPRFT and the MIIT jointly promulgated the Administrative Provisions on Internet Audio-Visual Program Service, or the Audio-Visual Program Provisions, on December 20, 2007, which came into effect on January 31, 2008 and was latest amended on August 28, 2015. Under the Audio-Visual Program Provisions, “internet audio-visual program services” is defined as activities of producing, redacting and integrating audio-visual programs, providing them to the general public via internet, and providing service for other people to upload and transmit audio-visual programs, and providers of internet audio-visual program services are required to obtain a License for Online Transmission of Audio-Visual Programs issued by SAPPRFT, or complete certain registration procedures with SAPPRFT. Providers of internet audiovisual program services must be either state-owned or state-controlled entities, and the business to be carried out by such providers must satisfy the overall planning and guidance catalog for internet audio-visual program service determined by SAPPRFT. In a press conference jointly held by SAPPRFT and MIIT to answer questions relating to the Audio-Visual Program Provisions in February 2008, SAPPRFT and MIIT clarified that providers of internet audio-visual program services who engaged in such services prior to the promulgation of the Audio-Visual Program Provisions are eligible to re-register with the relevant authorities and continue their operation of internet audio-visual program services so long as those providers did not violate the relevant laws and regulations in the past. On May 21, 2008, SAPPRFT issued a Notice on Relevant Issues Concerning Application and Approval of License for the Online Transmission of Audio-Visual Programs, which further sets out detailed provisions concerning the application and approval process regarding the License for Online Transmission of Audio-Visual Programs. The notice also states that providers of internet audio-visual program services that engaged in such services prior to the promulgation of the Audio-Visual Program Provisions are eligible to apply for the license so long as their violation of the laws and regulations is minor in scope and can be rectified in a timely manner and they have no records of violation during the last three months prior to the promulgation of the Audio-Visual Program Provisions. Further, on March 30, 2009, SAPPRFT promulgated the Notice on Strengthening the Administration of the Content of Internet Audio-Visual Programs, which reiterates the pre-approval requirements for the audio-visual programs transmitted via the internet, including through mobile networks, where applicable, and prohibits certain types of internet audio-visual programs containing violence, pornography, gambling, terrorism, superstition or other similarly prohibited elements.

On March 17, 2010, SAPPRFT promulgated the Provisional Implementation of the Tentative Categories of Internet Audio-Visual Program Services, or the Categories, which clarified the scope of Internet audio-visual programs services, which was amended on March 10, 2017. According to the Categories, there are four categories of Internet audio-visual program services which are further divided into seventeen sub-categories. The third sub-category to the second category covers the making and editing of certain specialized audio-visual programs concerning, among other things, educational content, and broadcasting such content to the general public online. However, there are still significant uncertainties relating to the interpretation and implementation of the Audio-Visual Program Provisions, in particular, the scope of “internet audio-visual programs.”

On November 4, 2016, the CAC issued Administrative Regulation on Internet Live Streaming Services, effective from December 1, 2016, according to which, “internet live streaming” refers to the activities of continuously releasing real-time information to the public based on the Internet in forms such as videos, audios, images and texts, and “internet live-streaming service providers” refers to the operators that provide Internet live-streaming platform service. In addition, the internet live-streaming service providers shall take various measures during operation of its services, such as examining and verifying the authenticity of the identification information and file such information for records.

On July 12, 2017, the CAC issued a Notice on Development of the Filing Work for Enterprises Providing Internet Live Streaming Services, which provides that all the companies providing internet live streaming services shall file with the local authority since July 15, 2017, otherwise the CAC or its local counterparts may impose administrative sanctions on such companies.

The PRC Constitution states that PRC law protects the freedom and privacy of communications of citizens and prohibits infringement of these rights. In recent years, PRC government authorities have enacted laws and regulations on internet use to protect personal information from any unauthorized disclosure.Pursuant to the Decision on Strengthening the Protection of Online Information issued by the Standing Committee of the National People’s Congress on December 28, 2012 and the Order for the Protection of Telecommunication and Internet User Personal Information issued by the MIIT in July 16, 2013, any collection and use of user personal information must be subject to the consent of the user, abide by the principles of legality, rationality and necessity and be within the specified purposes, methods and scopes.Pursuant to the Ninth Amendment to the Criminal Law issued by the Standing Committee of the National People’s Congress in August 2015, which became effective in November 2015, any internet service provider that fails to fulfill the obligations related to internet information security administration as required by applicable laws and refuses to rectify upon orders, shall be subject to criminal penalty for the result of (i) any dissemination of illegal information in large scale; (ii) any severe effect due to the leakage of the client’s information; (iii) any serious loss of criminal evidence; or (iv) other severe situation, and any individual or entity that (i) sells or provides personal information to others in a way violating the applicable law, or (ii) steals or illegally obtains any personal information, shall be subject to criminal penalty in severe situation.

Pursuant to the PRC Cyber Security Law issued by the Standing Committee of the National People’s Congress and effective on June 1, 2017, “personal information” refers to all kinds of information recorded by electronic or otherwise that can be used to independently identify or be combined with other information to identify individuals’ personal information including but not limited to: individuals’ names, dates of birth, ID numbers, biologically identified personal information, addresses and telephone numbers, etc. The Cyber Security Law also provides that: (i) to collect and use personal information, network operators shall follow the principles of legitimacy, rightfulness and necessity, disclose rules of data collection and use, clearly express the purposes, means and scope of collecting and using the information, and obtain the consent of the persons whose data is gathered; (ii) network operators shall neither gather personal information unrelated to the services they provide, nor gather or use personal information in violation of the provisions of laws and administrative regulations or the scopes of consent given by the persons whose data is gathered; and shall dispose of personal information they have saved in accordance with the provisions of laws and administrative regulations and agreements reached with users; (iii) network operators shall not divulge, tamper with or damage the personal information they have collected, and shall not provide the personal information to others without the consent of the persons whose data is collected. However, if the information has been processed and cannot be recovered and thus it is impossible to match such information with specific persons, such circumstance is an exception.

Pursuant to the Provisions on Internet Security Supervision and Inspection by Public Security Organs, which was promulgated by the Ministry of Public Security and effective on November 1, 2018, the public security departments are authorized to carry out internet security supervision and inspection of the internet service providers from the following aspects, among others: (i) whether the service providers have completed the recordation formalities for online entities, and filed the basic information on and the changes of the accessing entities and users; (ii) whether they have established and implemented the cybersecurity management system and protocols, and appointed the persons responsible for cybersecurity; (iii) whether the technical measures for recording and retaining users’ registration information and weblog data are in place according to the law; (iv) whether they have taken technical measures to prevent computer viruses, network attacks and network intrusion; (v) whether they have adopted preventive measures to tackle the information that is prohibited to be issued or transmitted by the laws and administrative regulations in the public information services; (vi) whether they provide technical support and assistance as required by laws to public security departments to safeguard national security and prevent and investigate on terrorist activities and criminal activities; and (vii) whether they have fulfilled the obligations of the grade-based cybersecurity protection and other obligations prescribed by the laws and administrative regulations.

Trademark license agreements must be filed with the Trademark Office for record. The PRC Trademark Law has adopted a “first-to-file” principle with respect to trademark registration. Where a trademark for which a registration has been made is identical or similar to another trademark which has already been registered or been subject to a preliminary examination and approval for use on the same kind of or similar commodities or services, the application for registration of such trademark may be rejected. Any person applying for the registration of a trademark may not prejudice the existing right first obtained by others, nor may any person register in advance a trademark that has already been used by another party and has already gained a “sufficient degree of reputation” through such party’s use.

Pursuant to the Foreign Currency Administration Rules, as amended, and various regulations issued by SAFE and other relevant PRC government authorities, RMB is freely convertible to the extent of current account items, such as trade related receipts and payments, interest and dividends. Capital account items, such as direct equity investments, loans and repatriation of investment, unless expressly exempted by laws and regulations, still require prior approval from SAFE or its local counterparts for conversion of RMB into a foreign currency, such as U.S. dollars, and remittance of the foreign currency outside of the PRC. Payments for transactions that take place within the PRC must be made in RMB. Foreign currency revenues received by PRC companies may be repatriated into China or retained outside of China in accordance with requirements and terms specified by SAFE.

According to the Circular on Administration of Foreign Exchange on Further Promoting the Facilitation of Cross-border Trade and Investment promulgated by SAFE on October 23, 2019, non-investment FIEs are allowed to make domestic equity investment with their capital funds provided that the existing negative list for foreign investment are complied with and the projects invested thereby in China are true and comply with applicable laws and regulations.

Wholly foreign-owned enterprises and Sino-foreign equity joint ventures in the PRC may pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC accounting standards and regulations. Additionally, these foreign-invested enterprises may not pay dividends unless they set aside at least 10% of their respective accumulated profits after tax each year, if any, to fund certain reserve funds, until such time as the accumulative amount of such fund reaches 50% of the enterprise’s registered capital. In addition, these companies also may allocate a portion of their after-tax profits based on PRC accounting standards to employee welfare and bonus funds at their discretion. These reserves are not distributable as cash dividends.

Regulations Relating to Foreign Exchange Registration of Overseas Investment by PRC Residents

SAFE Circular on Relevant Issues Relating to Domestic Resident’s Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or Circular 37, issued by SAFE and effective in July 4, 2014, regulates foreign exchange matters in relation to the use of special purpose vehicles, or SPVs, by PRC residents or entities to seek offshore investment and financing and conduct round trip investment in China. Under Circular 37, a SPV refers to an offshore entity established or controlled, directly or indirectly, by PRC residents or entities for the purpose of seeking offshore financing or making offshore investment, using legitimate domestic or offshore assets or interests, while “round trip investment” refers to the direct investment in China by PRC residents or entities through SPVs, namely, establishing foreign-invested enterprises to obtain the ownership, control rights and management rights. Circular 37 requires that, before making contribution into an SPV, PRC residents or entities are required to complete foreign exchange registration with the SAFE or its local branch. SAFE Circular 37 further provides that option or share-based incentive tool holders of a non-listed SPV can exercise the options or share incentive tools to become a shareholder of such non-listed SPV, subject to registration with SAFE or its local branch.

PRC residents or entities who have contributed legitimate domestic or offshore interests or assets to SPVs but have yet to obtain SAFE registration before the implementation of Circular 37 shall register their ownership interests or control in such SPVs with SAFE or its local branch. An amendment to the registration is required if there is a material change in the SPV registered, such as any change of basic information (including change of such PRC residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. Failure to comply with the registration procedures set forth in Circular 37, or making misrepresentation on or failure to disclose controllers of foreign-invested enterprise that is established through round-trip investment, may result in restrictions on the foreign exchange activities of the relevant foreign-invested enterprises, including payment of dividends and other distributions, such as proceeds from any reduction in capital, share transfer or liquidation, to its offshore parent or affiliate, and the capital inflow from the offshore parent, and may also subject relevant PRC residents or entities to penalties under PRC foreign exchange administration regulations. On February 13, 2015, SAFE further promulgated the Circular on Further Simplifying and Improving the Administration of the Foreign Exchange Concerning Direct Investment, or SAFE Circular 13, which took effect on June 1, 2015. This SAFE Circular 13 has amended SAFE Circular 37 by requiring PRC residents or entities to register with qualified banks rather than SAFE or its local branch in connection with their establishment or control of an offshore entity established for the purpose of overseas investment or financing. SAFE Circular 13 further provides that annual inspection of inbound foreign direct investments and outbound overseas direct investments is canceled. Instead,

relevant entities or individuals, as the case may be, shall register data and information with respect to their inbound foreign direct investments and outbound overseas direct investment interests with SAFE.

Pursuant to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, or Circular 7, issued by SAFE in February 2012, employees, directors, supervisors and other senior management participating in any stock incentive plan of an overseas publicly listed company who are PRC citizens or who are non-PRC citizens residing in China for a continuous period of not less than one year, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain other procedures. If we fail to complete the SAFE registrations, such failure may subject us to fines and legal sanctions and may also limit our ability to contribute additional capital into our wholly foreign-owned subsidiary in China and limit such subsidiary’s ability to distribute dividends to us.

In addition, the State Administration for Taxation has issued certain circulars concerning employee share options or restricted shares. Under these circulars, the employees working in the PRC who exercise share options or are granted restricted shares will be subject to PRC individual income tax. The PRC subsidiaries of such overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold individual income taxes of those employees who exercise their share options. If the employees fail to pay or the PRC subsidiaries fail to withhold their income taxes according to relevant laws and regulations, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities.

A loan made by a foreign entity as direct or indirect shareholder in an FIE is considered to be foreign debt in China and is regulated by various laws and regulations, including the Regulation of the People’s Republic of China on Foreign Exchange Administration, the Interim Provisions on the Management of Foreign Debts, the Statistical Monitoring of Foreign Debts Tentative Provisions, the Detailed Rules for the Implementation of Provisional Regulations on Statistics and Supervision of External Debt, and the Administrative Measures for Registration of Foreign Debts. Under these rules and regulations, a shareholder loan in the form of foreign debt made to a PRC entity does not require the prior approval of SAFE. However, such foreign debt must be registered with and recorded by SAFE or its local branches within 15 business days after entering into the foreign debt contract. Pursuant to these rules and regulations, the maximum amount of the aggregate of (i) the outstanding balance of foreign debts with a term not longer than one year, and (ii) the accumulated amount of foreign debts with a term longer than one year, of an FIE shall not exceed the difference between its registered total investment and its registered capital, or Total Investment and Registered Capital Balance.

On January 12, 2017, PBOC promulgated Notice of the People’s Bank of China on Issues Concerning Macro Prudential Management of Full Scale Cross-border Financing or PBOC Circular 9. According to PBOC Circular 9, PBOC established a cross-broader financing regulation system based on the capital or net assets of the micro main body under macro prudential rules, and the legal entities and financial institutions established in PRC including the branches of foreign banks registered in China but excluding government financing vehicles and real estate enterprise, may carry out cross-border financing of foreign currency in accordance with relevant regulations of such system. PBOC Circular 9 provides that, among other things, the outstanding amount of the foreign currency for the entities in cross-border financing shall be limited to the Upper Limit of the Risk Weighted Balance of such entity, which shall be calculated according to the formula provided in PBOC Circular 9; the enterprise shall, after signing the contract for cross-border financing, but not later than three business days before the withdrawal of the borrowing funds, file with the local branches of SAFE for the cross-border financing through SAFE’s capital project information system. PBOC Circular 9 also provides that during the one-year period started from January 11, 2017, foreign-invested enterprises may choose one method to carry out cross-broader financing in foreign currency either according to PBOC Circular 9 or according to the Interim Provisions on the Management of Foreign Debts. After the end of such one-year period, the method of foreign-invested enterprises to carry out cross-broader financing in foreign currency will be determined by PBOC and SAFE. To date, though the one-year period has expired, no further regulations or guidance promulgated by PBOC and SAFE in this regard.

The Enterprise Income Tax Law enacted by the National People’s Congress and the Implementing Rules of the Enterprise Income Tax Law promulgated by the State Council, or collectively, the PRC EIT Law, apply a uniform 25% enterprise income tax rate to both foreign-invested enterprises and domestic enterprises, except where tax incentives are granted to special industries and projects. Enterprises qualified as “High and New Technology Enterprises” are entitled to a 15% enterprise income tax rate rather than the 25% uniform statutory tax rate. The preferential tax treatment continues as long as an enterprise can retain its “High and New Technology Enterprise” status. Enterprise income tax for qualified small profit enterprises shall be at a reduced tax rate of 20%. Under the PRC EIT Law and its implementation regulations, dividends generated from the business of a PRC subsidiary after January 1, 2008 and payable to its foreign investor may be subject to a withholding tax rate of 10% if the PRC tax authorities determine that the foreign investor is a non-resident enterprise, unless there is a tax treaty with China that provides for a preferential withholding tax rate. Distributions of earnings generated before January 1, 2008 are exempt from PRC withholding tax.

Under the PRC EIT Law, an enterprise established outside China with “de facto management bodies” within China is considered a “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. A circular issued by the State Administration of Taxation, or SAT, in April 2009 regarding the standards used to classify certain Chinese-invested enterprises controlled by Chinese enterprises or Chinese enterprise groups and established outside of China as “resident enterprises,” or the SAT Circular 82, clarified that dividends and other income paid by such PRC “resident enterprises” will be considered PRC-source income and subject to PRC withholding tax, currently at a rate of 10%, when paid to non-PRC enterprise shareholders. The SAT Circular 82 also subjects such PRC “resident enterprises” to various reporting requirements with the PRC tax authorities. Under the implementation regulations to the PRC EIT Law, a “de facto management body” is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise. In addition, the SAT Circular 82 specifies that certain PRC-invested overseas enterprises controlled by a Chinese enterprise or a Chinese enterprise group in the PRC will be classified as PRC resident enterprises if the following are located or resided in the PRC: (i) senior management personnel and departments that are responsible for daily production, operation and management; (ii) financial and personnel decision making bodies; (iii) key properties, accounting books, the company seal, and minutes of board meetings and shareholders’ meetings; and (iv) half or more of the senior management or directors who have the voting rights.

Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise may be reduced to 5% from a standard rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC enterprise and certain other conditions are satisfied. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to apply the reduced withholding tax rate: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident enterprise throughout the 12 months prior to receiving the dividends. The SAT promulgated the Administrative Measures for Non-resident Taxpayers to Enjoy Treatment under Treaties, or SAT Circular 35, which became effective on January 1, 2020. SAT Circular 35 provides that non-resident enterprises are not required to obtain preapproval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. Accordingly, Sunlands HK may be able to benefit from the 5% withholding tax rate for the dividends it receives from Wuhan Zhibo and Tianjin Alaman, if it satisfies the conditions prescribed under SAT Circular 81 and other relevant tax rules and regulations. However, according to SAT Circular 81 and SAT Circular 35, if the relevant tax authorities consider the transactions or arrangements we have are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

On February 3, 2015, the SAT issued the Announcement of the State Administration of Taxation on Several Issues Concerning the Enterprise Income Tax on Indirect Property Transfer by Non-resident Enterprises, or SAT Bulletin 7, extends its tax jurisdiction to transactions involving the transfer of taxable assets through offshore transfer of a foreign intermediate holding company. Pursuant to SAT Bulletin 7, where a non-resident enterprise indirectly transfers properties such as equity in PRC resident enterprises without any justifiable business purposes and aiming to avoid the payment of enterprise income tax, such indirect transfer must be reclassified as a direct transfer of equity in PRC resident enterprise. To assess whether an indirect transfer of PRC taxable properties has reasonable commercial purposes, all arrangements related to the indirect transfer must be considered comprehensively and factors set forth in SAT Bulletin 7 must be comprehensively analyzed in light of the actual circumstances. In addition, SAT Bulletin 7 has introduced safe harbors for internal group restructurings and the purchase and sale of equity through a public securities market.

Where non-resident investors were involved in our private equity financing, if such transactions were determined by the tax authorities to lack reasonable commercial purpose, we and our non-resident investors may become at risk of being required to file a return and taxed under SAT Bulletin 7 and/or SAT Bulletin 37 and we may be required to expend valuable resources to comply with SAT Bulletin 7 and/or SAT Bulletin 37 or to establish that we should not be held liable for any obligations under SAT Bulletin 7 and/or SAT Bulletin 37.

PRC Value-added Tax (“VAT”) in lieu of Business Tax (the “VAT Pilot Program”)

On March 23, 2016, the Ministry of Finance and the SAT issued the Circular on Comprehensively Promoting the Pilot Program of the Collection of Value-added Tax in Lieu of Business Tax. Effective from May 1, 2016, the PRC tax authorities collect VAT in lieu of Business Tax on a trial basis within the territory of China, and in industries such as construction industries, real estate industries, financial industries, and living service industries.

On September 30, 2019, the Ministry of Finance and the SAT jointly issued the Announcement on Clarifying the VAT Weighted Deduction Policy for the Living Services, or Bulletin 87, pursuant to which, from October 1, 2019 to December 31, 2021, the taxpayers engaging in providing living services are allowed to deduct additional 15% of the deductible input VAT amount for the current period from the payable tax. The taxpayers providing production and living services refer to the taxpayers whose sales generated from the postal service, telecommunication service, modern service, living service account for more than 50% of the total sales. On March 21, 2019, the SAT issued the Notice on the Matters Concerning Deepening the Reform of Value Added Tax, or SAT Bulletin 14, which further clarifies the methods of declaring the aforesaid additional deductible input VAT amount.

Since January 2020, in accordance with Announcement of the Ministry of Finance and the SAT [2020] No.8 and Announcement of the Ministry of Finance and the SAT [2021] No.7, due to the Novel coronavirus (“COVID-19”) pandemic, the VAT on certain services was temporarily exempted until March 31, 2021.

We are subject to laws and regulations governing our relationship with our employees, including wage and hour requirements, working and safety conditions, and social insurance, housing funds and other welfare. The compliance with these laws and regulations may require substantial resources.

Pursuant to the PRC Labor Law effective as of January 1, 1995 (as amended on December 29, 2018) and the PRC Labor Contract Law effective as of January 1, 2008 (as amended on December 28, 2012), a written labor contract shall be executed by employer and an employee when the employment relationship is established, and an employer is under an obligation to sign an unlimited-term labor contract with any employee who has worked for the employer for ten consecutive

years. Further, if an employee requests or agrees to renew a fixed-term labor contract that has already been entered into twice consecutively, the resulting contract must have an unlimited term, with certain exceptions. The employer must also pay severance to an employee in nearly all instances where a labor contract, including a contract with an unlimited term, is terminated or expires. All employers must compensate their employees equal to at least the local minimum wage standards. All employers are required to establish a system for labor safety and sanitation, strictly abide by state rules and standards and provide employees with appropriate workplace safety training. In addition, the government has continued to introduce various new labor-related regulations after the Labor Contract Law. Among other things, new annual leave requirements mandate that annual leave ranging from 5 to 15 days is available to nearly all employees and further require that the employer compensate an employee for any annual leave days the employee is unable to take in the amount of three times his daily salary, subject to certain exceptions. Moreover, all PRC enterprises are generally required to implement a standard working time system of eight hours a day and forty hours a week, and if the implementation of such standard working time system is not appropriate due to the nature of the job or the characteristics of business operation, the enterprise may implement a flexible working time system or comprehensive working time system after obtaining approvals from the relevant authorities.

In addition, employers in China are obliged to pay contributions to the social insurance plan and the housing fund plan for their employees, and such contribution amount payable shall be calculated based on the employee actual salary in accordance with the relevant regulations. According to the Notice on the Reduction or Exemption of Enterprises’ Social Security Contributions in Phases jointly promulgated by the Ministry of Human Resources and Social Security, the Ministry of Finance and the SAT on February 20, 2020, with effect from February 2020, with certain exceptions, based on the epidemic impact and the fund threshold, small, medium and micro enterprises and the enterprises in Hubei may be exempted from contributions to the basic pension insurance, unemployment insurance, and work injury insurance, with the exemption period not exceed five months; and contributions to such three social security contribution items by other social security participating organizations (excluding State agencies and institutions) such as large enterprises may be reduced by 50% by, with the reduction period not exceed three months.

From August 2017 to November 2021, Wuhan Zhibo, a wholly-owned subsidiary of us, entered into a series of contractual arrangements with Beijing Sunlands, Tianjin Shangde, Beijing Odysseus, Wuhan Hadeliang, Wuhan Jiayan and Beijing

Lingding, as well as their shareholders and, where applicable, operating subsidiaries of them, through which we obtained effective control over, and became the primary beneficiary of these VIEs.

From December 2020 to February 2021, Tianjin Alaman, a wholly-owned subsidiary of us, entered into a series of contractual arrangements with Wuhan Fangtang, Beijing Zhiziyuanshui and Beijing Feibian, as well as their shareholders and, where applicable, operating subsidiaries of them, through which we obtained effective control over, and became the primary beneficiary of these VIEs.

In addition, in June 2021, Wuhan Zhongtudao, a wholly-owned subsidiary of us, entered into a series of contractual arrangements with Wuhan Xiaoyan, as well as its shareholders, through which we obtained effective control over, and became the primary beneficiary of, Wuhan Xiaoyan.

Through the below contractual agreements, Wuhan Zhibo, Tianjin Alaman and Wuhan Zhongtudao, our wholly owned subsidiaries, have (i) the power to direct the activities of the VIEs and their subsidiaries that most significantly affect their economic performance; and (ii) the right to receive substantially all the benefits from these VIEs and their subsidiaries. They are therefore considered the primary beneficiaries of the VIEs and their subsidiaries, and accordingly, the results of operations, assets and liabilities of the VIEs and their subsidiaries are consolidated in our financial statements.

Exclusive Technical Consultation and Service Agreement. Under the exclusive technical consultation and service agreement among Wuhan Zhibo, Beijing Sunlands and the subsidiaries of Beijing Sunlands, Wuhan Zhibo has the exclusive right to provide, among other things, technical consultation and services to Beijing Sunlands and the subsidiaries of Beijing Sunlands, and Beijing Sunlands and the subsidiaries of Beijing Sunlands agree to accept all the consultation and services provided by Wuhan Zhibo. Without Wuhan Zhibo’s prior written consent, Beijing Sunlands and the subsidiaries of Beijing Sunlands are prohibited from engaging any third party to provide any services contemplated by this agreement. In addition, Wuhan Zhibo has exclusive and proprietary ownership, rights and interests in any and all intellectual properties arising out of or created during the performance of this agreement. Beijing Sunlands and the subsidiaries of Beijing Sunlands agree to pay a quarterly service fee to Wuhan Zhibo at an aggregate amount of a certain percentage ranging from 10% to 100% of Beijing Sunlands and the subsidiaries of Beijing Sunlands monthly revenue. Unless terminated by Wuhan Zhibo, this agreement will remain effective until the dissolution of Beijing Sunlands and the subsidiaries of Beijing Sunlands. Without Wuhan Zhibo’s prior written consent, Beijing Sunlands and the subsidiaries of Beijing Sunlands do not have the right to terminate this exclusive technical consultation and service agreement. Wuhan Zhibo, Tianjin Alaman and Wuhan Zhongtudao have entered into exclusive technical consultation and service agreements with the rest of the VIEs, respectively. The terms of such agreements are substantially the same as the agreement of Beijing Sunlands summarized above.

Business Operation Agreement. Under the business operation agreement, each of Beijing Sunlands, the subsidiaries of Beijing Sunlands and the shareholders of Beijing Sunlands confirmed and agreed that, without Wuhan Zhibo’s prior written consent, it shall not make any transaction that has a material adverse effect on the assets, business, personnel, obligations, rights or operations of Beijing Sunlands and the subsidiaries of Beijing Sunlands, including but not limited to sale or purchase of any assets or rights exceeding RMB50,000, incurrence of any encumbrance on any of its assets, including intellectual property rights, in favor of a third party, amendment of its articles of association or business scope, or change of its normal operation procedures. Beijing Sunlands, the subsidiaries of Beijing Sunlands and the shareholders of Beijing Sunlands shall accept and execute opinions and instructions of Wuhan Zhibo in connection with the employee engagement and dismissal, daily operations and financial management systems. The shareholders of Beijing Sunlands shall elect or appoint the candidates recommended by Wuhan Zhibo as Beijing Sunlands’ directors and supervisors, and procure the appointment of Beijing Sunlands’ chairman of the board and senior management pursuant to Wuhan Zhibo’s designation.

This agreement will remain binding until dissolution of Beijing Sunlands and all the subsidiaries of Beijing Sunlands. Wuhan Zhibo, Tianjin Alaman and Wuhan Zhongtudao have entered into business operation agreements with the rest of the VIEs, respectively. The terms of such agreements are substantially the same as the agreement of Beijing Sunlands summarized above.

Equity Interest Pledge Agreement. Under the equity interest pledge agreement among Wuhan Zhibo, the shareholders of Beijing Sunlands and Beijing Sunlands, the shareholders of Beijing Sunlands pledged all of their equity interests in Beijing Sunlands to Wuhan Zhibo as security for performance of the obligations of Beijing Sunlands and its shareholders under the exclusive technical consultation and service agreement, the option agreement and the business operation agreement. The shareholders of Beijing Sunlands shall instruct Beijing Sunlands not to distribute any dividends and shall not approve any profit distribution plan. If any of the specified events of default occurs, Wuhan Zhibo may exercise the right to enforce the pledges after giving a notice of default to the shareholders of Beijing Sunlands. Wuhan Zhibo may assign any and all of its

rights and obligations under the equity interest pledge agreement to its designee(s) at any time. The equity interest pledge agreement is binding on the shareholders of Beijing Sunlands and their successors. Wuhan Zhibo, Tianjin Alaman and Wuhan Zhongtudao have entered into equity interest pledge agreements with the rest of the VIEs, respectively. The terms of such agreements are substantially the same as the agreement of Beijing Sunlands summarized above.

Option Agreement. Pursuant to the option agreement among Wuhan Zhibo, the shareholders of Beijing Sunlands and Beijing Sunlands, each of the shareholders irrevocably granted Wuhan Zhibo a right to purchase, or designate a third party to purchase, equity interests in Beijing Sunlands then held by each shareholder at once or at multiple times at any time in part or in whole at Wuhan Zhibo’s sole and absolute discretion to the extent permitted by PRC law. The shareholders of Beijing Sunlands shall promptly surrender all considerations they received from the exercise of the options to Wuhan Zhibo or the designated third party free of charge. Without Wuhan Zhibo’s prior written consent, the shareholders of Beijing Sunlands shall not, individually or collectively, make or procure Beijing Sunlands to make in any transaction or conduct that has a material adverse effect on the assets, liabilities, operations, equity and other legal rights of Beijing Sunlands. Without Wuhan Zhibo’s prior written consent, Beijing Sunlands shall not enter into any contract exceeding RMB50,000, except the contracts in the ordinary course of the business. Beijing Sunlands shall not be dissolved or liquidated without prior written consent by Wuhan Zhibo. The shareholders of Beijing Sunlands waive their rights of pre-emption in regard to the transfer of equity interest by any other shareholder of Beijing Sunlands to Wuhan Zhibo as instructed.

Wuhan Zhibo, Tianjin Alaman and Wuhan Zhongtudao have entered into option agreements with the rest of the VIEs, respectively. The terms of such agreements are substantially the same as the agreement of Beijing Sunlands summarized above.

Powers of Attorney. Pursuant to the powers of attorney executed by the shareholders of Beijing Sunlands, the shareholders of Beijing Sunlands each irrevocably authorized Wuhan Zhibo to act on their respective behalf as exclusive agent and attorney with respect to all rights of shareholders concerning all equity interests held by each of them in Beijing Sunlands, including but not limited to propose to convene shareholder meetings, accept any notice with respect to the convening and proceeding of the shareholder meeting, attend shareholder meetings, sign the shareholders resolutions on their behalf, exercise all the shareholder’s rights and Beijing Sunlands’ articles of association (including but not limited to voting rights and the sale transfer, pledge or dispose of all equity interests held in part or in whole) and designate and appoint on their respective behalf the president, directors, supervisors, Chief Executive Officer, Chief Financial Officer and other senior management members of Beijing Sunlands.

Pursuant to the spousal consent letters executed by the spouses of the general partners of entities as the shareholders of Beijing Sunlands, the signing spouse confirmed and agreed that the equity interests of Beijing Sunlands are the own property of their spouses and shall not constitute the jointly possessed property of the couples. The spouses also irrevocably waived any potential right or interest that may be granted by operation of applicable law in connection with the equity interests of Beijing Sunlands held by their spouses.

The spouses of the shareholders of the rest of the VIEs, as applicable, also signed the spousal consent letters respectively, the terms of which are substantially the same as the spousal consent letter of Beijing Sunlands summarized above.

As a result of the contractual arrangements above, Wuhan Zhibo, Tianjin Alaman and Wuhan Zhongtudao bear the economic risks and receive the economic benefits of the VIEs, hold the power in directing the significant activities of the VIEs, and are the primary beneficiary of the VIEs. Therefore, we have consolidated the financial results of the VIEs and their subsidiaries in our consolidated financial statements.

In the opinion of Tian Yuan Law Firm, our PRC legal counsel, the contractual arrangements among our wholly-owned PRC subsidiaries, the VIEs, the VIEs’ respective shareholders and the VIEs’ respective subsidiaries are valid, binding and enforceable under current PRC law.

However, these contractual arrangements may not be as effective in providing control as direct ownership. There are substantial uncertainties regarding the interpretation and application of current or future PRC laws and regulations. For a

description of the risks related to our corporate structure, please see “Item 3. Key Information—3.D. Risk Factors—Risk Factors—Risks Related to Our Corporate Structure.”

Our current principal executive offices are located at Building 4-6, Chaolai Science Park, No. 36 Chuangyuan Road, Chaoyang District, Beijing, the People’s Republic of China. We maintain offices in Beijing, China, with an aggregate of approximately 24,436 square meters. These facilities currently accommodate our management headquarters, as well as our sales and marketing, course and educational content development, and general and administrative activities. We also maintain offices in Wuhan, China, with an aggregate of approximately 26,208 square meters, to support part of our sales and marketing activities. In addition, we maintain offices in Guangzhou, China, with an aggregate of approximately 11,448 square meters, to support our sales and marketing activities as well as general and administrative activities.

We lease all of the facilities that we currently occupy from independent third parties. We believe that the facilities that we currently lease are adequate to meet our needs for the foreseeable future.

You should read the following discussion together with our consolidated financial statements and the related notes included elsewhere in this annual report on Form 20-F. This discussion may contain forward-looking statements about our business and operations based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those we currently anticipate as a result of many factors, including those we describe under “Item 3.D. Risk Factors” and elsewhere in this annual report on Form 20-F.

We operate in China’s online post-secondary and professional education market, and our results of operations and financial condition are significantly affected by general factors affecting this market. Drivers for our growth include China’s rapid economic growth, continued urbanization, and rising per capita disposable income, all of which have allowed Chinese households, particularly working adults, to spend more disposable income on education. In addition, driven by a strong desire for employment, career promotion, salary increases and local residence qualification, post-secondary and professional education in China has grown rapidly in the past several years and is expected to continue to grow in the future.

Changes to China’s economy and GDP growth also have a material impact on the online post-secondary and professional education market. In addition, the industry we operate in is fragmented, and we face competition from traditional offline players. At the same time, our results are subject to changes in the regulatory regime governing China’s education industry, particularly uncertainties relating to online education services. The PRC government regulates various aspects of our business and operations, including the qualification and licensing requirements for entities that provide online education services and limitations on foreign investments in the online education industry.

Additionally, we believe that our results of operations and financial condition are also affected by company-specific factors, including the factors discussed below.

Our ability to respond to the evolving industry landscape and drive student acceptance of online education format

As an online service provider, we benefited significantly from the increasing proliferation of the internet, in particular the mobile internet, in China. In recent years, driven by the increasing number of internet users and mobile penetration rates, China’s online education industry has experienced an annual growth of more than 20%.

We believe that the online education format, as compared to traditional in-person classroom teaching, is superior as it breaks down the time and location barriers of offline education format and offers students more a flexible, convenient and cost-effective alternative. As a result, online education format has become increasingly popular among students, taking away market share from traditional offline players. For this reason, we believe our ability to continue to grow our net revenues and

gross billings significantly depends on our ability to continue to convert students to embrace online education formats over traditional offline education format.

Our ability to increase the number of our students and new student enrollments at optimal pricing

Our net revenues and gross billings primarily consist of tuition payments from our students and are therefore affected by the number of our students and new student enrollments and the pricing of our educational services.

In 2019, 2020 and 2021, our new student enrollments were 363,013, 434,240 and 434,228, respectively, and the numbers of our students were 1,039,733, 1,130,650 and 1,104,630, respectively. Our new student enrollments remained relatively stable, primarily due to the increase in professional skills and general interest courses catering to growing demands for diverse personal education, partially offset by the decrease in STE courses. We are seeking to offer a broader range of courses, foster a more a social and entertaining learning experience, and use cutting-edge technologies, particularly AI, to improve students’ learning experience and outcomes which we believe would help to achieve positive results in our new student enrollments in the long run. See “3.D. Risk Factors—Risks Related to Our Business—If we fail to manage our business growth effectively, the success of our business model will be compromised.”

Our ability to continue to increase the number of our students and new student enrollments is primarily driven by factors including the quality of our education services, the range and attractiveness of our course offerings, our brand reputation, our ability to convert leads into student enrollments cost-effectively, and the availability of loans from third-party credit providers to our students. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business—We may face risks associated with the installment tuition payment plan we offer to our students.” Our ability to attract prospective students in target markets and expand our course offerings has a direct impact on maintaining growths in the number of our students and new student enrollments, which in turn is subject to several other factors largely beyond our control, including the perception of the effectiveness of online education as compared to offline, classroom-based courses and the popularity of the degrees, diplomas and professional certifications our students are pursuing.

Our pricing is affected by the overall demand, the prices and availability of competing courses, perception of the quality and effectiveness of our course offerings, and the income levels that our students expect to achieve upon passing the exams that they are pursuing through taking our courses.

We typically receive tuition from our students (or third-party credit providers in the case of students taking loans for their tuition) upfront at the time of sale of our course packages. The tuition we collect from a student is initially recorded as deferred revenue and is generally recognized proportionally throughout the duration of the programs that student has enrolled in. For the year ended December 31, 2021, the weighted average length of our degree-or diploma-oriented post-secondary courses was approximately 24 months, and the weighted average length of our professional certification preparation and professional skills courses was approximately 7 months. As of December 31, 2019, 2020 and 2021, our deferred revenues were RMB3,228.8 million, RMB3,024.4 million and RMB2,348.2 million (US$368.5 million), respectively.

We continually evaluate our mix of course length. As we make these evaluations, we may market and sell courses with shorter or longer durations in order to balance among various goals, including satisfying student needs, driving revenue growth, and improving visibility of future earnings, which may affect our ability to increase our net revenues on a continuous basis. For example, if we increase the percentage of courses with longer durations in our total course offerings, our net revenues for a given period may reduce as an increasing part of our revenues may be deferred and recognized across longer periods. Any material change in our mix of course length could have a significant impact on our results of operations.

We depend on our ability to sell and market our services in a cost-effective manner to maintain and improve our operating margins.

Sales and marketing expenses have historically represented a substantial portion of our total operating expenses. In 2019, 2020 and 2021, our sales and marketing expenses were RMB1,792.3 million, RMB2,123.6 million and RMB1,748.4 million (US$274.4 million), respectively. The decrease in our sales and marketing expenses from 2020 to 2021 was mainly due to (i) lower spending on branding and marketing activities; and (ii) declined compensation expenses related to our sales and marketing personnel. Our sales and marketing expenses are primarily composed of marketing spending and expenses incurred in relation to sales and marketing personnel. Our ability to lower our sales and marketing expenses as a percentage

of gross billings depends on our ability to improve sales and marketing efficiency and leverage our existing brand value and word-of-mouth referrals in our sales and marketing efforts. In 2019, 2020 and 2021, our marketing effectiveness ratio, as measured by dividing our marketing spending by our gross billings, was 40.2%, 46.9% and 41.6%, respectively.

We have acquired many of our existing students through search engine marketing channels, mobile marketing channels and, to a lesser extent, offline channels. Further, we rely on a large sales force to provide counseling-oriented sales services to convert sales leads into enrollments. As such, the cost-effectiveness of our sales and marketing depends heavily on our ability to enhance returns from different marketing channels, as well as to improve the efficiency of our counseling-oriented sales activities. We also plan to further strengthen our mobile marketing endeavors, which we believe are particularly critical to attracting prospective students who are not yet aware of solutions available to satisfy their desire to pursue post-secondary and professional education. These initiatives have placed, and will continue to place, significant strains on our ability to sell and market our course offerings in an efficient and cost-effective manner.

We derive substantially all of our net revenues from tuition that we charge our students for the course packages that they purchase from us. In 2019, 2020 and 2021, we generated net revenues of RMB2,193.9 million, RMB2,203.8 million and RMB2,507.8 million (US$393.5 million), respectively.

We generally bill our students for the entire course tuition upfront at the time of sale of our course packages. The tuition we collect from a student is initially recorded as deferred revenue and is generally recognized proportionally over a weighted average period of 24 months for our degree-or diploma-oriented post-secondary courses and a weighted average period of 7 months for our professional certification preparation and professional skills courses for the year ended December 31, 2021. As of December 31, 2019, 2020 and 2021, we had deferred revenue of RMB3,228.8 million, RMB3,024.4 million and RMB2,348.2 million (US$368.5 million), respectively. For a reconciliation of our gross billings and net revenues, see “—Non-GAAP Financial Measures.”

We recorded cost of revenues of RMB396.3 million, RMB387.3 million and RMB376.2 million (US$59.0 million) in 2019, 2020 and 2021, respectively. Compensation for teachers and mentors accounted for a significant portion of our cost of revenues. In 2019, 2020 and 2021, the labor costs that we recorded as cost of revenues were RMB234.4 million, RMB220.2 million and RMB209.1 million (US$32.8 million), respectively, accounting for 59.1%, 56.9% and 55.6%, respectively, of our cost of revenues for the same periods. Our cost of revenues also included fees to educational institutions for exams and services, cooperation costs, rental expenses, teaching materials costs, insurance costs, server management and bandwidth costs in connection with live streaming, payment processing costs and related equipment costs. See “Item 4.

Information on the Company—4.B. Business Overview—Business—Our Tuition and Fees.” We expect our cost of revenues to increase in an absolute amount in line with our expansion of business and student base growth.

Our operating expenses consist of sales and marketing expenses and, to a lesser extent, general and administrative expenses and product development expenses. The following table sets forth our operating expenses, in absolute amounts and as percentages of total operating expenses, for the years indicated:

The following table sets forth a breakdown of our sales and marketing expenses, in absolute amounts and as percentages of total sales and marketing expenses, for the years indicated:

Our expenses incurred in relation to sales and marketing personnel consist of (i) salaries paid to our sales and marketing personnel employed by us; (ii) commissions for the sales and marketing personnel employed by us; and (iii) business process outsourcing service fees and commissions. The marketing spending includes expenses relating to our search engine marketing channels and mobile marketing channels.

We have historically incurred, and are expected to continue to incur, significant sales and marketing expenses as we invested substantially in our sales, branding and marketing efforts and expanding our sales and marketing team to increase student enrollments and gain market share.

Our general and administrative expenses primarily consist of (i) compensation for our senior executives and administrative personnel, (ii) rentals of premises occupied by our senior executives and administrative personnel, and (iii) administrative and other expenses. We expect our general and administrative expenses to remain stable in the foreseeable future.

Our product development expenses primarily consist of (i) compensation for our course and educational content development professionals and technology development personnel, and (ii) rentals of premises occupied by our course and educational content development professionals and technology development personnel. We expect our product development expenses to remain stable in the foreseeable future.

The following table sets forth our consolidated results of operations for the years indicated. This information should be read together with our consolidated financial statements and related notes included elsewhere in this annual report.

Our net revenues increased by 13.8% from RMB2,203.8 million in 2020 to RMB2,507.8 million (US$393.5 million) in 2021, primarily due to the effectiveness of our strategic direction and execution excellence in the expansion of professional certification preparation and professional skills courses.

Our cost of revenues decreased by 2.9% from RMB387.3 million in 2020 to RMB376.2 million (US$59.0 million) in 2021. The decrease was mainly due to a decrease in the compensation expenses for teachers and mentors from RMB220.2 million in 2020 to RMB209.1 million (US$32.8 million) in 2021, and a decrease in insurance-related costs incurred for our integrated online education service package purchased by students from RMB40.6 million in 2020 to RMB5.7 million (US$0.9 million) in 2021. The decrease in our cost of revenues was partially offset by an increase in expenses related to service fees to educational institutions from RMB83.3 million to RMB105.5 million (US$16.6 million) in 2021.

As a result of the foregoing, our gross profit increased by 17.3% from RMB1,816.5 million in 2020 to RMB2,131.6 million (US$334.5 million) in 2021, and gross margin increased from 82.4% in 2020 to 85.0% in 2021.

Our operating expenses decreased by 18.2% from RMB2,465.5 million in 2020 to RMB2,017.4 million (US$316.6 million) in 2021.

Our sales and marketing expenses decreased by 17.7% from RMB2,123.6 million in 2020 to RMB1,748.4 million (US$274.4 million) in 2021. The decrease was mainly due to (i) lower spending on branding and marketing activities; and (ii) declined compensation expenses related to our sales and marketing personnel. As of December 31, 2021, we deployed 3,001 sales and marketing personnel in conducting sales activities.

Our general and administrative expenses decreased by 24.6% from RMB275.4 million in 2020 to RMB207.6 million (US$32.6 million) in 2021, primarily due to the decrease in office and compensation expenses.

Our product development expenses decreased by 7.8% from RMB66.5 million in 2020 to RMB61.3 million (US$9.6 million) in 2021. The decrease was primarily due to the decrease in the compensation expenses incurred related to our product and technology development personnel.

Other income for 2021 was RMB39.2 million (US$6.1 million), compared with RMB203.2 million in 2020. The decrease was primarily because value-added tax exemption offered by the relevant authorities as part of the national COVID-19 relief effort came to an end in March 2021.

As a result of the foregoing, our net income for 2021 was RMB212.4 million (US$33.3 million), compared with net loss of RMB431.0 million in 2020.

See “Item 5. Operating and Financial Review and Prospects—5.A. Operating Results—Year Ended December 31, 2020 Compared to Year Ended December 31, 2019” beginning on page 72 of our Form 20-F for the fiscal year ended December 31, 2020 filed with the Securities and Exchange Commission on April 16, 2021 (Securities Act File No. 333-234009).

We use gross billings and EBITDA, each a non-GAAP financial measure, in evaluating our operating results and for financial and operational decision-making purposes.

We define gross billings for a specific period as the total amount of cash received for the sale of course packages, net of the total amount of refunds paid in such period. For a more detailed discussion of our tuition refund policy, see “Item 4. Information on the Company—4.B. Business Overview—Business—Our Tuition and Fees.” Our management uses gross billings as a performance measurement because we generally bill our students for the entire course tuition at the time of sale of our course packages and recognize revenue proportionally over a period.

EBITDA is defined as net loss/income excluding depreciation and amortization, interest expense, interest income, and income tax expenses. We believe that gross billings and EBITDA provide valuable insight into the sales of our course packages and the performance of our business.

These non-GAAP financial measures should not be considered in isolation from, or as a substitute for, their respective most directly comparable financial measure prepared in accordance with GAAP. A reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP measure has been provided in the tables included below. Investors are encouraged to review the reconciliation of the historical non-GAAP financial measures to their respective most directly comparable GAAP financial measures. As gross billings and EBITDA have material limitations as analytical metrics and may not be calculated in the same manner by all companies, they may not be comparable to other similarly titled measures used by other companies. In light of the foregoing limitations, you should not consider gross billings and EBITDA as a substitute for, or superior to, their respective most directly comparable financial measures prepared in accordance with GAAP. We encourage investors and others to review our financial information in its entirety and not rely on a single financial measure.

We are incorporated in the Cayman Islands. Under the current law of the Cayman Islands, we are not subject to income or capital gains tax. In addition, dividend payments are not subject to withholding tax in the Cayman Islands.

Our wholly owned subsidiary in Hong Kong is subject to a two-tiered income tax rate for taxable income earned in Hong Kong with effect from April 1, 2018. The first HK$2 million of profits earned by Sunlands HK will be taxed at 8.25%, while the remaining profits will continue to be taxed at the existing 16.5% tax rate. Payments of dividends by our subsidiaries to us are not subject to withholding tax in Hong Kong.

Our subsidiaries and our consolidated VIEs and their subsidiaries in China are companies incorporated under PRC law and, as such, are subject to PRC enterprise income tax on their taxable income in accordance with the relevant PRC income tax laws. Pursuant to the PRC Enterprise Income Tax Law, or PRC EIT Law, a uniform 25% enterprise income tax rate is generally applicable to both foreign-invested enterprises and domestic enterprises, except where a special preferential rate applies. For example, enterprises qualified as “High and New Technology Enterprises” are entitled to a 15% enterprise income tax rate rather than the 25% uniform statutory tax rate. Pursuant to the Notice on Implementation of Inclusive Tax Relief Policy for Small and Low-profit Enterprises jointly issued by the Ministry of Finance and the SAT on January 17, 2019 and the Announcement on Issues Relating to Implementation of Inclusive Income Tax Relief Policy for Small and Low-profit Enterprises issued by SAT on January 18, 2019, during the period from January 1, 2019 to December 31, 2021, the portion of annual taxable income amount of a small and low-profit enterprise which does not exceed RMB1 million shall be computed at a reduced rate of 25% as taxable income amount, and be subject to a 20% enterprise income tax rate, and the portion of annual taxable income amount which exceeds RMB1 million but does not exceed RMB3 million shall be computed at a reduced rate of 50% as taxable income amount, and be subject to a 20% enterprise income tax rate. The enterprise income tax is calculated based on the entity’s global income as determined under PRC tax laws and accounting standards. Further, pursuant to the Announcement on Implementation of Income Tax Incentives for Small and Low-profit Enterprises and Individually-owned Businesses jointly issued by the Ministry of Finance and the SAT on April 2, 2021, during the period from January 1, 2021 to December 31, 2022, for the portion of annual taxable income amount of a small and low-profit enterprise which does not exceed RMB1 million, the enterprise income tax shall be reduced by 50%, in addition to the incentives aforesaid.

Our services are subject to VAT at the rate of 6% for general-VAT-payer entities in accordance with tax rule, except that certain subsidiaries were subject to a simple VAT collection method at a rate of 3% before June 2019. Since January 2020, in accordance with Announcement of the Ministry of Finance and the SAT [2020] No.8 and Announcement of the Ministry of Finance and the SAT [2021] No.7, due to the Novel coronavirus (“COVID-19”) pandemic, the VAT on certain services was temporarily exempted until March 31, 2021.

As a Cayman Islands holding company, we may receive dividends from our PRC subsidiaries through Sunlands Online Education HK Limited. The PRC EIT Law and its implementing regulations provide that dividends paid by a PRC entity to a non-resident enterprise for income tax purposes is subject to PRC withholding tax at a rate of 10%, subject to reduction by an applicable tax treaty with China. Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise may be reduced to 5% from a standard

rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC enterprise and certain other conditions are met. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or SAT Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to apply the reduced withholding tax rate: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident enterprise throughout the 12 months prior to receiving the dividends. The State Administration of Taxation promulgated the Administrative Measures for Non-resident Taxpayers to Enjoy Treatment under Treaties, or SAT Circular 35, which became effective on January 1, 2020. SAT Circular 35 provides that nonresident enterprises are not required to obtain pre-approval from the relevant tax authority in order to enjoy the reduced withholding tax. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. Accordingly, Sunlands Online Education HK Limited may be able to benefit from the 5% withholding tax rate for the dividends it receives from Wuhan Zhibo and Tianjin Alaman, if it satisfies the conditions prescribed under SAT Circular 81 and other relevant tax rules and regulations. However, according to SAT Circular 81 and SAT Circular 35, if the relevant tax authorities consider the transactions or arrangements we have are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

If our holding company in the Cayman Islands or any of our subsidiaries outside of China were deemed to be a “resident enterprise” under the PRC EIT Law, it would be subject to enterprise income tax on its worldwide income at a rate of 25%. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and ADS holders.”

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect the reported amounts of our assets and liabilities and the disclosure of our contingent assets and liabilities at the end of each fiscal period and the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these judgments and estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and assumptions that we believe to be reasonable, which together form our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our accounting policies require a higher degree of judgment than others in their application.

The selection of critical accounting policies, the judgments and other uncertainties affecting application of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors that should be considered when reviewing our financial statements. For further information on our critical accounting policies, see Note 2 to our consolidated financial statements.

An accounting estimate is considered critical if it requires to be made based on assumptions about matters that are highly uncertain at the time such estimate is made, and if different accounting estimates that reasonably could have been used, or changes in the accounting estimate that are reasonably likely to occur periodically, could materially impact the consolidated financial statements. The following descriptions of critical accounting estimates should be read in conjunction with our consolidated financial statements and other disclosures included in this annual report. For further information, see Note 2 to our consolidated financial statements in this annual report.

We follow five steps for revenue recognition under ASC 606: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation. Our revenue is reported net of discount, value added tax and related surcharges. The primary sources of our revenues are as follows:

For online education services, we provide an integrated online education service package to students, including online live streaming audio-video interactive course content, recorded previous live audio-video course content, quiz banks, online chat rooms, and educational contents. The services and goods provided in the package are highly interdependent and interrelated in the context of the contract and are only considered accessory services to the online live streaming and recorded courses which are not distinct and are not sold standalone. Therefore, our integrated online education services package is accounted for as a single performance obligation.

The transaction price of the integrated online education service package is determined by the contract amount net of any discount. Students are offered a full, unconditional refund within 24 hours upon enrollment. Prior to June 2019, undelivered courses was eligible for refund, excluding registration fees, within 7 days after enrollment. For course contracts entered after June 2019, undelivered courses is eligible for refund during the entire service period, excluding registration fees.

Revenues for online education services are recognized on a straight line basis over the service period from the registration day to the day on which the service period ends.

For certain online courses, we provided students the right to apply for refund or cash incentive if certain pre-agreed conditions are achieved. We estimated the variable consideration to be earned to the extent it was probable that a significant reversal of cumulative revenue recognized would not occur when the uncertainty associated with the variable consideration was resolved and recognized revenue over time from the registration day to the day on which the service period ended on a straight line basis. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price were based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that was reasonably available.

For certain online courses, the service period includes a regular period plus an extended period. We offer students an extended service period after the regular period if certain pre-agreed conditions are met. Based on historical passing rates, and forecasted passing rates due to continuous improvement of service quality, we apply and categorize the students by portfolio (1) eligible to extended period and (2) not eligible to extended period and estimates the portion of each portfolio. We recognize the revenue on each portfolio over time from the registration day to the day on which the service is expected to end on a straight line basis.

For certain online courses, we offer a bundled service including an integrated online education service package with insurance coverage for tuition refund. If certain refund conditions are met, students could claim the insurance equal to full or partial amount of the service fee. We identify that the integrated online education service package and the insurance service are two separate performance obligations as students benefit from each service on its own and they are separately identifiable in the contract. We record revenue generated from online education services with insurance coverage on a gross basis as we are acting as the principal to fulfill all obligation and control all the services transferred to the students. The total service fee is allocated to each performance obligation based on selling prices, which are estimated based on the expected cost of satisfying each performance obligation plus an estimated margin. Revenues for integrated online education service and the insurance service are recognized over their respective service periods on a straight line basis from the registration day to the day on which the service period ends as the students simultaneously receives and consumes the benefits provided by these two performance obligations.

We utilize the asset and liability method in accounting for income taxes. Deferred tax assets and liabilities reflect the estimated future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax expense or benefit is the result of changes in the deferred tax asset and liability. Valuation allowances are established when necessary to reduce deferred tax assets where it is more likely than not that the deferred tax assets will not be realized. We make estimates,

assumptions and judgments to determine its provision for its income taxes, deferred tax assets and liabilities, and any valuation allowance recorded against deferred tax assets. We assess the likelihood that our deferred tax assets will be recovered from future taxable income, and to the extent we believe that recovery is not likely, we established a valuation allowance.

We account for uncertain tax positions by reporting a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. Tax benefits are recognized from uncertain tax positions when we believe that it is more-likely-than-not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. We recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

We financed our operations from cash generated from operating activities as well as proceeds from the issuance and sale of our ordinary shares. As of December 31, 2021, we had RMB676.7 million (US$106.2 million) in cash, cash equivalents and restricted cash, the majority of which were held by our Cayman Island holding company, PRC subsidiaries and VIEs and VIEs’ subsidiaries in China. Our cash and cash equivalents consist primarily of bank deposits and are primarily denominated in Renminbi. We believe that our current cash and anticipated cash flow from operations will be sufficient to meet our anticipated cash needs, including our cash needs for working capital and capital expenditures, for at least the next 12 months. We believe there is no substantial doubt to operate as a going concern, as a result, the accompanying consolidated financial statements have been prepared on a going concern basis, and do not reflect any adjustments relating to the recoverability and reclassification of assets and liabilities that might have been necessary if we were unable to continue as a going concern.

We incurred net losses of RMB395.2 million and RMB431.0 million for the years ended December 31, 2019, 2020, respectively, and recorded net profit of RMB212.4 million (US$33.3 million), for the year ended December 31 2021. We had negative working capital of RMB641.4 and RMB779.4 million (US$122.3 million) as of December 31, 2020 and 2021. The major factor for our negative working capital position as of December 31, 2020 and 2021 was deferred revenue.

We intend to finance our future working capital requirements and capital expenditures from existing cash balance, cash generated from operating activities and funds raised from financing activities. We may, however, require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our existing cash is insufficient to meet our requirements, we may seek to issue debt or equity securities or obtain additional credit facilities. Financing may be unavailable in the amounts we need or on terms acceptable to us, if at all. Issuance of additional equity securities, including convertible debt securities, would dilute our earnings per share. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating and financial covenants that restrict our operations and our ability to pay dividends to our shareholders. If we are unable to obtain additional equity or debt financing as required, our business operations and prospects may suffer.

As a holding company with no material operations of our own, we conduct our operations primarily through subsidiaries and consolidated VIEs in China. We are permitted under PRC laws and regulations to provide funding to our PRC subsidiaries in China through capital contributions or loans, subject to the approval of government authorities and limits on the amount of capital contributions and loans. In addition, our subsidiaries in China may provide Renminbi funding to our consolidated VIEs only through entrusted loans. The ability of our subsidiaries in China to make dividends or other cash payments to us is subject to various restrictions under PRC laws and regulations. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—We may rely on dividends and other distributions on equity paid by our PRC subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our PRC subsidiaries to make payments to us could have a material and adverse effect on our ability to conduct our business” and “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC

resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and ADS holders.”

The following table sets forth a summary of our cash flows for the years indicated:

For a summary of our cash flows in 2019, see “Item 5. Operating and Financial Review and Prospects—5.B. Liquidity and Capital Resources—Cash Flows and Working Capital” beginning on page 80 of our Form 20-F for the fiscal year ended December 31, 2020 filed with the Securities and Exchange Commission on April 16, 2021 (Securities Act File No. 333-234009).

Net cash used in operating activities was RMB373.3 million (US$58.6 million) in 2021. The difference between our net income of RMB212.4 million (US$33.3 million), after netting non-cash reconciliation items, and the net cash used in operating activities was mainly due to (i) a decrease in deferred costs of RMB129.9 million (US$20.4 million), (ii) an increase prepaid expenses and other current assets of RMB24.9 million (US$3.9 million), (iii) a decrease in right-of-use asset of RMB126.5 million (US$19.9 million), and (iv) a decrease in accrued expenses and other current liabilities of RMB22.6 million (US$3.5 million); all offset by (i) a decrease in deferred revenue of RMB646.7 million (US$101.5 million), and(ii) a decrease in lease liability of RMB144.8 million (US$22.7 million). Deferred revenue consisted primarily of tuition paid upfront by our students at the time of purchase of course packages. Deferred cost consisted primarily of the incremental sales commissions and service fees relating to obtaining of customer contracts which is expected to be recovered and capitalized.

Net cash used in operating activities was RMB188.6 million in 2020. The difference between our net loss of RMB431.0 million, after netting non-cash reconciliation items, and the net cash used in operating activities was mainly due to (i) a decrease in deferred costs of RMB120.7 million , (ii) prepaid expenses and other current assets of RMB63.7 million, and (iii) a decrease in right-of-use asset of RMB110.1 million, and (iv) an increase in accrued expenses and other current liabilities of RMB172.2 million; all offset by (i) a decrease in deferred revenue of RMB204.3 million, and

(ii) a decrease in lease liability of RMB93.2 million. Deferred revenue consisted primarily of tuition paid upfront by our students at the time of purchase of course packages. Deferred cost consisted primarily of the incremental sales commissions and service fees relating to obtaining of customer contracts which is expected to be recovered and capitalized.

Net cash provided by investing activities was RMB342.7 million (US$53.8 million) in 2021, which was primarily attributable to proceeds from maturity of short-term investments of RMB2,166.9 million (US$340.0 million), partially offset by purchase of short-term investments of RMB1,833.7 million (US$287.7 million).

Net cash used in investing activities was RMB349.3 million in 2020, which was primarily attributable to purchase of short-term investments of RMB2,195.6 million, partially offset by proceeds from maturity of short-term investments of RMB1,895.9 million.

Net cash used in financing activities in 2021 was RMB38.9 million (US$6.1 million), which was primarily attributable to repayment of bank debt of RMB34.0 million (US$5.3 million) and cash used for repurchase of Class A ordinary shares of RMB4.9 million (US$0.8 million).

Net cash used in financing activities in 2020 was RMB59.1 million, which was primarily attributable to repayment of bank debt of RMB32.5 million and repurchase of Class A ordinary shares of RMB26.6 million.

Our material cash requirements as of December 31, 2021 and any subsequent interim period primarily include our operating lease commitments, investment commitments, long-term loans, capital expenditures and working capital requirements.

Our operating lease commitments consist of the commitments under the lease agreements for our office premises. We lease our office facilities under non-cancelable operating leases with various expiration dates. The majority of our operating lease commitments are related to our office lease agreements in China.

Our investment commitments represent long-term investments in a limited partnership.

Our long-term loans represent future maximum commitment relating to the principal amount and interests in connection with two loan agreements dated August 29, 2018 and November 21, 2018 in the aggregate principal amount of RMB260.0 million (US$40.8 million) and one loan agreement dated July 5, 2021 with the principal amount of RMB61.5 million (US$9.7 million). The annual interest rate for the loan agreements dated in 2018 was 1.472% prior to April 15, 2021 and 1.25% after April 15, 2021 on top of base rate of one-year interest rate released by the People's Bank of China. The annual interest rate for the loan agreement dated in 2021 was 1.05% on top of base rate of one-year interest rate released by the People's Bank of China. Under the agreements, we are obligated to repay the loans in equal instalment every three months with maturity terms ranging from 8 years to 10 years. We repaid RMB32.5 million, RMB32.5 million and RMB34.0 million (US$5.3 million) for the principals of loans during the years ended December 31, 2019, 2020 and 2021, respectively.

The following table sets forth our contractual obligations as of December 31, 2021:

Our capital expenditures are incurred primarily in connection with purchases of IT infrastructure equipment and buildings necessary to support our operations. Our capital expenditures were RMB25.5 million, RMB27.0 million and RMB16.5 million (US$2.6 million), respectively, for the years ended December 31, 2019, 2020 and 2021. We intend to fund our future working capital requirements and capital expenditures from our existing cash balance, cash generated from operating activities and funds raised from financing activities.

We have not entered into any financial guarantees or other commitments to guarantee the payment obligations of any third parties. We do not have retained or contingent interests in assets transferred. We have not entered into contractual arrangements that support the credit, liquidity or market risk for transferred assets. We do not have obligations that arise or could arise from variable interests held in an unconsolidated entity, or obligations related to derivative instruments that are both indexed to and classified in our own equity, or not reflected in the statement of financial position.

Other than those shown above, we did not have any significant capital and other commitments, long-term obligations, or guarantees as of December 31, 2021.

Sunlands Technology Group is a holding company with no material operations of its own. We conduct our operations primarily through our subsidiaries and our consolidated VIEs in China. As a result, our ability to pay dividends depends upon dividends paid by our subsidiaries. If our subsidiaries or any newly formed subsidiaries incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends to us.

In addition, our subsidiaries in China are permitted to pay dividends to us only out of their retained earnings, if any, as determined in accordance with the Accounting Standards for Business Enterprise as promulgated by the Ministry of Finance of the PRC, or PRC GAAP. In accordance with PRC company laws, our consolidated VIEs in China must make appropriations from their after-tax profit to non-distributable reserve funds including (i) statutory surplus fund and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of our consolidated VIEs. Appropriation to discretionary surplus fund is made at the discretion of our consolidated VIEs. Pursuant to the law applicable to China’s foreign investment enterprise, our subsidiaries that are foreign investment enterprise in the PRC have to make appropriation from their after-tax profits, as determined under PRC GAAP, to reserve funds including (i) general reserve fund, (ii) enterprise expansion fund and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the reserve fund has reached 50% of the registered capital of our subsidiary. Appropriation to the other two reserve funds are at our subsidiary’s discretion.

As an offshore holding company, we are permitted under PRC laws and regulations to provide funding from the proceeds of our offshore fund raising activities to our PRC subsidiaries only through loans or capital contributions, and to our consolidated affiliated entity only through loans, in each case subject to the satisfaction of the applicable government registration and reporting, approval requirements. As a result, there is uncertainty with respect to our ability to provide prompt financial support to our PRC subsidiaries and consolidated VIEs when needed. Notwithstanding the foregoing, our PRC subsidiaries may use their own retained earnings (rather than Renminbi converted from foreign currency denominated capital) to provide financial support to our consolidated affiliated entity either through entrustment loans from our PRC subsidiaries to our consolidated VIEs or direct loans to such consolidated affiliated entity’s nominee shareholders, which would be contributed to the consolidated variable entity as capital injections. Such direct loans to the nominee shareholders would be eliminated in our consolidated financial statements against the consolidated affiliated entity’s share capital.

We have focused on and will continue to invest in our technology system, which supports all key aspects of our online platform and is designed to optimize for scalability and flexibility. See “Item 4. Information on the Company—4.B. Business Overview.”

For details of our material licenses and approvals, see “Item 4. Information on the Company—4.B. Business Overview—Licenses and Approvals.”

Other than as disclosed elsewhere in this annual report on Form 20-F, we are not aware of any trends, uncertainties, demands, commitments or events for the year ended December 31, 2020 that are reasonably likely to have a material and adverse effect on our net revenues, income, profitability, liquidity or capital resources, or that would cause the disclosed financial information to be not necessarily indicative of future results of operations or financial condition.

For our critical accounting estimates, see “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Critical Accounting Policies and Estimates.”

We adopted an employee share incentive plan in October 2017, or the 2017 Plan. The purpose of the 2017 Plan is to attract and retain exceptionally qualified personnel and to encourage them to acquire a proprietary interest in our growth and performance.

As of the date of this annual report, we are authorized to grant options or share purchase rights to purchase up to an aggregate of 433,053 ordinary shares under the 2017 Plan. As of the same date, options to purchase an aggregate number of 31,546 ordinary shares are outstanding, all of which had vested and become exercisable. All of the ordinary shares reserved and issuable upon the exercise of options granted pursuant to the 2017 Plan shall, upon issuance of such ordinary shares, be designated as Class C ordinary shares.

Types of Awards. The 2017 Plan permits the awards of options, share appreciation rights, rights to dividends and dividend equivalent right, restricted shares and restricted share units and other rights or benefits under the 2017 Plan.

Plan Administration. A committee formed in accordance with applicable stock exchange rules shall administer the 2017 Plan, unless otherwise determined by the board of directors.

Eligibility. Our employees and consultants are eligible to participate in the 2017 Plan. An employee or consultant who has been granted an award may, if he or she is otherwise eligible, be granted additional awards.

Designation of Award. Each award under the 2017 Plan is designated in an award agreement, which is a written agreement evidencing the grant of an award executed by the company and the grantee, including any amendments thereto.

Conditions of Award. The board of directors or any entity appointed by the board of directors to administer the 2017 Plan shall determine the provisions, terms, and conditions of each award including, but not limited to, the award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, and form of payment upon settlement of the award.

Terms of Award. The term of each award is stated in the award agreement between the company and the grantee of such award.

Transfer Restrictions. Unless otherwise determined by the administrator of the 2017 Plan, no award and no right under any such award, shall be assignable, alienable, saleable or transferable by the employee otherwise than by will or by the laws of descent and distribution unless, if so determined by the administrator of the 2017 Plan, the employee may, in the manner established by such administrator, designate a beneficiary or beneficiaries to exercise the rights of the employee, and to receive any property distributable, with respect to any award upon the death of the employee.

Exercise of Award. Any award granted under the 2017 Plan is exercisable at such times and under such conditions as determined by the administrator under the terms of the 2017 Plan and specified in the award agreement. An award is deemed to be exercised when exercise notice has been given to the company in accordance with the terms of the award by the person entitled to exercise the award and full payment for the shares with respect to which the award is exercised.

Amendment, Suspension or Termination of the 2017 Plan. The administrator of the 2017 Plan may amend, alter, suspend, discontinue or terminate this 2017 Plan, or any award agreement hereunder or any portion hereof or thereof at any time; provided, however, that no such amendment, alteration, suspension, discontinuation or termination shall be made without (i) shareholder approval with such legally mandated threshold for a resolution of the shareholders if such approval is necessary to comply with any tax or regulatory requirement for which or with which the administrator of the 2017 Plan deems it necessary or desirable to qualify or (ii) comply shareholder approval with such threshold for a resolution of the shareholders in respect of such amendment, alteration, suspension, discontinuation or termination as provided in our memorandum and articles of association for any amendment to the 2017 Plan that increases the total number of shares reserved for the purposes of the 2017 Plan, and (iii) with respect to any award agreement, the consent of the affected employee, if such action would materially and adversely affect the rights of such employee under any outstanding award.

As of the date of the annual report, there was no outstanding equity awards granted to our directors and executive officers under the 2017 Plan. As of the same date, our other employees as a group held options to purchase 31,546 Class C ordinary shares, with an exercise price of US$84.75 per share.

For discussions of our accounting policies for awards granted pursuant to the 2017 Plan, see Note 2 to our consolidated financial statements.

Our Board of Directors consists of seven directors, including two independent directors, namely Mr. Yifan Li and Mr. Zheng Zhao. A director is not required to hold any shares in our company to qualify to serve as a director. The Corporate Governance Rules of the NYSE generally require that a majority of an issuer’s board of directors must consist of independent directors. However, the Corporate Governance Rules of the NYSE permit foreign private issuers like us to follow “home country practice” in certain corporate governance matters. We rely on this “home country practice” exception and do not have a majority of independent directors serving on our Board of Directors.

A director who to his knowledge is in any way, whether directly or indirectly, interested in a contract or arrangement or proposed contract or arrangement with our company is required to declare the nature of his or her interest at a meeting of our directors. A general notice given to the directors by any director to the effect that (i) he is a member or officer of any specified company or firm and is to be regarded as interested in any contract or transaction with that company or firm, or (ii) he is to be regarded as interested in any contract or transaction which may, after the date of such notice, be made with a specified person who is connected with him, shall be deemed a sufficient declaration of interest for the purposes of voting on a resolution in respect to a contract or transaction in which he/she has an interest. A director may vote in respect of any contract or proposed contract or arrangement notwithstanding that he may be interested therein and if he does so, his vote shall be counted and he may be counted in the quorum at any meeting of the directors at which any such contract or proposed contract or arrangement is considered, subject to any separate requirement for Audit Committee approval under applicable laws or the rules of the New York Stock Exchange, and unless disqualified by the chairman of the relevant board meeting. Our Board of Directors may exercise all of the powers of our company to borrow money, to mortgage or charge its

undertaking, property and assets (present and future) and uncalled capital, and to issue debentures, bonds and other securities whenever money is borrowed or as security for any debt, liability or obligation of our company or of any third party. None of our directors has a service contract with us that provides for benefits upon termination of service as a director.

We have established an audit committee, a compensation committee and a nominating and corporate governance committee under our Board of Directors. We have adopted a charter for each of the three committees. Each committee’s members and functions are described below.

Our audit committee consists of Mr. Yifan Li and Mr. Zheng Zhao, and is chaired by Mr. Yifan Li. We have determined that each of Mr. Yifan Li and Mr. Zheng Zhao satisfies the requirements of Section 303A of the Corporate Governance Rules of the NYSE and meet the independence standards under Rule 10A-3 under the Securities Exchange Act of 1934, as amended. We have determined that Mr. Yifan Li qualifies as an “audit committee financial expert.” The audit committee oversees our accounting and financial reporting processes and the audits of our financial statements. The audit committee is also responsible for, among other things:

Our compensation committee consists of Mr. Peng Ou, Mr. Tongbo Liu and Mr. Zheng Zhao, and is chaired by Mr. Peng Ou. We have determined that Mr. Zheng Zhao satisfies the “independence” requirements of Section 303A of the Corporate Governance Rules of the NYSE. The compensation committee assists our Board of Directors in reviewing and approving the compensation structure, including all forms of compensation, relating to our directors and executive officers. The compensation committee is also responsible for, among other things:

Our nominating and corporate governance committee consists of Mr. Peng Ou, Mr. Tongbo Liu and Mr. Zheng Zhao, and is chaired by Mr. Peng Ou. We have determined that Mr. Zheng Zhao satisfies the “independence” requirements of Section 303A of the Corporate Governance Rules of the NYSE. The nominating and corporate governance committee assists our Board of Directors in selecting individuals qualified to become our directors and in determining the composition of our Board of Directors and its committees. The nominating and corporate governance committee is also responsible for, among other things:

Under Cayman Islands law, our directors owe fiduciary duties to our company, including a duty of loyalty, a duty to act honestly and a duty to act in what they consider in good faith to be in our best interests. Our directors must also exercise their powers only for a proper purpose. Our directors also owe to our company a duty to exercise the skill they actually possess and such care and diligence that a reasonable prudent person would exercise in comparable circumstances. It was previously considered that a director need not exhibit in the performance of his duties a greater degree of skill than may

reasonably be expected from a person of his knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands. In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association, as amended and restated from time to time. Our company has the right to seek damages if a duty owed by our directors is breached. In limited exceptional circumstances, a shareholder may have the right to seek damages in our name if a duty owed by our directors is breached. The functions and powers of our Board of Directors include, among others, (i) convening shareholders’ annual general meetings and reporting its work to shareholders at such meetings, (ii) declaring dividends, (iii) appointing officers and determining their terms of offices and responsibilities, and (iv) approving the transfer of shares of our company, including the registering of such shares in our share register.

Our officers are elected by and serve at the discretion of the board. Each director is not subject to a term of office and holds office until such time as his successor takes office or until the earlier of his death, resignation or removal from office by ordinary resolution of the shareholders. A vacancy on the board created by the removal of a director may be filled by ordinary resolution or by the affirmative vote of a simple majority of the remaining directors present and voting at a board meeting. Mr. Peng Ou shall have the right to appoint or remove any Management Director (as defined under our fourth amended and restate memorandum and articles of association) by delivering a written notice to our company, provided that the Founder shall not be entitled to exercise such right if he or his affiliates do not hold any shares. A director will be removed from office automatically if, among other things, the director (i) becomes bankrupt or makes any arrangement or composition with his creditors; (ii) dies or is found by our company to be of unsound mind; (iii) resigns by notice in writing to our company; (iv) is prohibited by law or the rules of the New York Stock Exchange from being a director; or (v) is removed from office pursuant to any other provisions of our fourth amended and restated memorandum and articles of association.

We had 2,880, 7,347 and 4,064 full-time employees as of December 31, 2019, 2020 and 2021, respectively. As of December 31, 2021, most of our employees were in Beijing, Guangzhou, Wuhan and Shenzhen.

The following table sets forth the number of our employees as of December 31, 2021:

We enter into employment contracts with our full-time employees which contain standard confidentiality and non-compete provisions. In addition to salaries and benefits, we provide performance-based bonuses for our full-time employees and commission-based compensation for our sales and marketing force.

Under PRC law, we participate in various employee social security plans that are organized by municipal and provincial governments for our PRC-based full-time employees, including pension, unemployment insurance, childbirth insurance, work-related injury insurance, medical insurance and housing insurance. We are required under PRC law to make contributions from time to time to employee benefit plans for our PRC-based full-time employees at specified percentages of the salaries, bonuses and certain allowances of such employees, up to a maximum amount specified by the local governments in China.

We believe that we maintain a good working relationship with our employees, and we have not experienced any material labor disputes in the past. None of our employees are represented by labor unions.

The following table sets forth information concerning the beneficial ownership of our ordinary shares as of March 31, 2022 by:

The calculations in the table below are based on 6,647,445 issued and outstanding ordinary shares as of March 31, 2022, comprising (i) 1,818,126 Class A ordinary shares, (ii) 826,389 Class B ordinary shares, and (iii) 4,002,930 Class C ordinary shares.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days, including through the exercise of any option, warrant, or other right or the conversion of any other security. These shares, however, are not included in the computation of the percentage ownership of any other person.

To our knowledge, as of March 31, 2022, 907,167 of our Class A ordinary shares were held by one record holder in the United States, which was The Bank of New York Mellon, the depositary of our ADR program. The number of beneficial owners of our ADSs in the United States is likely to be much larger than the number of record holders of our ordinary shares in the United States.

We are not aware of any arrangement that may, at a subsequent date, result in a change of control of our company.

Please refer to “Item 6. Directors, Senior Management and Employees—6.E. Share Ownership.”

See “Item 6. Directors, Senior Management and Employees—6.A. Directors and Senior Management—Employment Agreements and Indemnification Agreements.”

See “Item 6. Directors, Senior Management and Employees—6.B. Compensation—Share Incentive Plan.”

We have appended consolidated financial statements filed as part of this annual report on Form 20-F.

From time to time, we may become a party to various legal or administrative proceedings arising in the ordinary course of our business. We are currently not a party to, and we are not aware of any threat of, any legal or administrative proceedings that, in the opinion of our management, are likely to have any material and adverse effect on our business, financial condition, cash flow or results of operations.

In June 2019, we, and certain of our current and former directors and officers and our underwriters in our initial public offering were named as defendants in a securities class action filed in the U.S. District Court for the Eastern District of New York. An amended complaint in this class action was filed in November 2019. The action, purportedly brought on behalf of a class of persons who allegedly suffered damages as a result of their trading in the ADSs, alleges that our registration statement on Form F-1 in connection with our March 2018 initial public offering contains materially false and misleading statements and omissions in violation of the U.S. federal securities laws. We filed a motion to dismiss the action in March 2020, which was denied by an order dated March 31, 2021. In July 2021, we filed a motion for judgment on the pleadings, which is fully briefed. Discovery has been stayed pending resolution of the motion for judgment on the pleadings. Accordingly, the lawsuit is still in its preliminary stages. We are currently unable to estimate the potential loss, if any, associated with the resolution of the lawsuit. We intend to defend the action vigorously. For risks and uncertainties relating to pending cases against us, see “Item 3. Key Information—3.D. Risk Factors—Risks Related to Our Business—We and certain of our directors and officers have been named as defendants in a shareholder class action lawsuit, which could have a material adverse impact on our business, financial condition, results of operation, cash flows and reputation.”

We have not previously declared or paid cash dividends and we currently do not plan to declare or pay any dividends on our shares or the ADSs representing our Class A ordinary shares. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

We are an exempted company incorporated in the Cayman Islands. We rely principally on dividends from our PRC subsidiaries for our cash requirements, including any payment of dividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiaries to pay dividends to us. See “Item 4. Information on the Company—4.B. Business Overview—Regulation—Regulations on Foreign Exchange—Dividend Distribution.”

Our Board of Directors has discretion as to whether to distribute dividends, subject to certain requirements of Cayman Islands law. Under Cayman Islands law, a Cayman Islands company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. Even if our Board of Directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the Class A ordinary shares underlying the ADSs to the depositary, as the registered holder of such Class A ordinary shares, and the depositary then will pay such amounts to the ADS holders in proportion to the Class A ordinary shares underlying the ADSs held by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder.

Except as otherwise disclosed in this report, we have not experienced any significant changes since the date of the annual financial statements included herein.

The ADSs representing our Class A ordinary shares have been listed on the New York Stock Exchange since March 23, 2018 under the symbol “STG.” Effective from August 31, 2021, the ratio of ADSs representing the Class A ordinary shares changed from each 25 ADSs representing one Class A ordinary share to each two ADSs representing one Class A ordinary share.

The ADSs representing our Class A ordinary shares have been listed on the New York Stock Exchange since March 23, 2018 under the symbol “STG.”

The following are summaries of material provisions of our fourth amended and restated memorandum and articles of association and the Companies Act (As Revised) of the Cayman Islands which we refer to as the “Companies Act” below insofar as they relate to the material terms of our ordinary shares.

General. Our authorized share capital is US$50,000 divided into 1,000,000,000 shares with a par value of US$0.00005 each, comprising (i) 796,062,195 Class A ordinary shares with a par value of US$0.00005 each, (ii) 826,389 Class B ordinary shares with a par value of US$0.00005 each, and (iii) 203,111,416 Class C ordinary shares with a par value of US$0.00005 each. Holders of ordinary shares have the same rights except for voting and conversion rights as set out in our fourth amended and restated memorandum and articles of association. All of our issued and outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. We may not issue share to bearer. Our shareholders who are non-residents of the Cayman Islands may freely hold and transfer their ordinary shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our Board of Directors subject to our fourth amended and restated memorandum and articles of association and the Companies Act. Our fourth amended and restated memorandum and articles of association provide that dividends may be declared and paid out of our profits, realized or unrealized. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Companies Act.

Voting Rights. In respect of all matters subject to shareholder vote, each Class A ordinary share is entitled to one vote, each Class B ordinary share is entitled to seven votes, and each Class C ordinary share is entitled to ten votes.

A quorum required for a meeting of shareholders consists of a majority of the votes attaching to the issued and outstanding shares entitled to vote at general meetings present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative. As a Cayman Islands exempted company, we are not obliged by the Companies Act to call shareholders’ annual general meetings. Our fourth amended and restated memorandum and articles of association provide that we may (but are not obliged to) in each year hold a general meeting as our annual general meeting in which case we will specify the meeting as such in the notices calling it, and the annual general meeting will be held at such time and place as may be determined by our directors. We, however, will hold an annual shareholders’ meeting during each fiscal year, as required by the Listing Rules at the NYSE. Each general meeting, other than an annual general meeting, shall be an extraordinary general meeting. Shareholders’ annual general meetings and any other general meetings of our shareholders may be called by a majority of our Board of Directors or our chairman and a majority of our Board of Directors or our chairman shall, upon requisition of shareholders holding not less 10% of all votes attaching to all issued and outstanding ordinary shares entitled to vote at general meetings, convene an extraordinary general meeting; however, our fourth amended and restated memorandum and articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders. Advance notice of at least fifteen (15) days is required for the convening of our annual general meeting and other general meetings unless such notice is waived in accordance with our articles of association.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting, while a special resolution also requires the affirmative vote of no less than two-thirds of the votes attaching to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting. A special resolution will be required for important matters such as making changes to our fourth amended and restated memorandum and articles of association.

Transfer of Ordinary Shares. Subject to the restrictions in our fourth amended and restated memorandum and articles of association as set out below, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our Board of Directors.

Our Board of Directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our Board of Directors may also decline to register any transfer of any ordinary share unless:

If our directors refuse to register a transfer of any share they shall, within two calendar months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required of the NYSE, be suspended and the register closed at such times and for such periods as our Board of Directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year.

Liquidation. On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of ordinary shares), if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to our company for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders in proportion to the par value of the shares held by them. Any distribution of assets or capital to a holder of ordinary share will be the same in any liquidation event.

Redemption, Repurchase and Surrender of Ordinary Shares. We may issue shares on terms that such shares are subject to redemption, at our option or at the option of the holders thereof, on such terms and in such manner as may be determined, before the issue of such shares, by our Board of Directors. Our company may also repurchase any of our shares provided that the manner and terms of such purchase have been approved by our Board of Directors or are otherwise authorized by our fourth memorandum and articles of association. Under the Companies Act, the redemption or repurchase of any share may be paid out of our company’s profits or out of the proceeds of a fresh issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if the company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Act no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding, or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration.

Variations of Rights of Shares. If at any time our share capital is divided into different classes or series of shares, the rights attached to any class or series of shares (unless otherwise provided by the terms of issue of the shares of that class or series), whether or not our company is being wound-up, may be varied with the consent in writing of a majority the holders of the issued shares of that class or series or with the sanction of an ordinary resolution at a separate meeting of the holders of the shares of the class or series. The rights conferred upon the holders of the shares of any class issued shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares.

Inspection of Books and Records. Holders of our ordinary shares have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records (other than copies of our memorandum and articles of association, our register of mortgages and charges, and any special resolutions passed by our shareholders). However, we will provide our shareholders with annual audited financial statements. See “—10.H. Document on Display.”

Issuance of Additional Shares. Our fourth amended and restated memorandum and articles of association authorizes our Board of Directors to issue additional ordinary shares from time to time as our Board of Directors shall determine, to the extent of available authorized but unissued shares.

Our fourth amended and restated memorandum and articles of association also authorizes our Board of Directors to, without the approval of our shareholders, establish from time to time one or more series of preferred shares and to determine, with respect to any series of preferred shares, the terms and rights of that series, including, among other things:

Our Board of Directors may issue preferred shares without action by our shareholders to the extent authorized but unissued. Issuance of these shares may dilute the voting power of holders of ordinary shares.

Anti-Takeover Provisions. Some provisions of our fourth amended and restated memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable, including provisions that authorize our Board of Directors to issue authorized preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

Exempted Company. We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except that an exempted company:

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on that shareholder’s shares of the company.

We have not entered into any material contracts other than in the ordinary course of business and other than those described in this annual report on Form 20-F.

See “Item 4. Information of the Company—4.B. Business Overview—Regulation—Regulations Relating to Foreign Exchange.”

The following discussion of Cayman Islands, PRC and United States federal income tax consequences of an investment in the ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This discussion does not deal with all possible tax consequences relating to an investment in the ADSs or ordinary shares, such as the tax consequences under state, local and other tax laws. To the extent that the discussion relates to matters of Cayman Islands tax law, it represents the opinion of Maples and Calder (Hong Kong) LLP, our Cayman Islands counsel. To the extent that the discussion relates to matters of PRC tax law, it represents the opinion of Tian Yuan Law Firm, our PRC legal counsel.

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation, and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us or holders of our ADSs or ordinary shares levied by the government of the Cayman Islands, except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of the ADSs or ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of the ADSs or ordinary shares, nor will gains derived from the disposal of the ADSs or ordinary shares be subject to Cayman Islands income or corporate tax.

Under the PRC EIT Law, which became effective on January 1, 2008 and amended on December 29, 2018, an enterprise established outside the PRC with “de facto management bodies” within the PRC is considered a “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. Under the implementation regulations to the PRC EIT Law, a “de facto management body” is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise.

In addition, the SAT Circular 82 issued by the SAT in April 2009 specifies that certain offshore incorporated enterprises controlled by PRC enterprises or PRC enterprise groups will be classified as PRC resident enterprises if the following are located or resident in the PRC: (a) senior management personnel and departments that are responsible for daily

production, operation and management; (b) financial and personnel decision making bodies; (c) key properties, accounting books, company seal, minutes of board meetings and shareholders’ meetings; and (d) half or more of the senior management or directors having voting rights. Further to SAT Circular 82, the SAT issued the SAT Bulletin 45, which took effect in September 2011, to provide more guidance on the implementation of SAT Circular 82. SAT Bulletin 45 provides for procedures and administration details of determination on resident status and administration on post-determination matters. Our company is a company incorporated outside the PRC. As a holding company, its key assets are its ownership interests in its subsidiaries, and its key assets are located, and its records (including the resolutions of its board of directors and the resolutions of its shareholders) are maintained, outside the PRC. As such, we do not believe that our company meets all of the conditions above or is a PRC resident enterprise for PRC tax purposes. For the same reasons, we believe our other entities outside of China are not PRC resident enterprises either. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.” There can be no assurance that the PRC government will ultimately take a view that is consistent with us. If the PRC tax authorities determine that our Cayman Islands holding company is a PRC resident enterprise for PRC enterprise income tax purposes, a number of unfavorable PRC tax consequences could follow. For example, a 10% withholding tax would be imposed on dividends we pay to our non-PRC enterprise shareholders (including the ADS holders). In addition, non-resident enterprise shareholders (including the ADS holders) may be subject to PRC tax on gains realized on the sale or other disposition of ADSs or ordinary shares, if such income is treated as sourced from within the PRC. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to our non-PRC individual shareholders (including the ADS holders) and any gain realized on the transfer of ADSs or ordinary shares by such shareholders may be subject to PRC tax at a rate of 20% (which, in the case of dividends, may be withheld at source by us). These rates may be reduced by an applicable tax treaty, but it is unclear whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC in the event that we are treated as a PRC resident enterprise. See “Item 3. Key Information—3.D. Risk Factors—Risks Related to Doing Business in China—If we are classified as a PRC resident enterprise for PRC enterprise income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders and ADS holders.”

The following is a discussion of the material U.S. federal income tax consequences to the U.S. Holders described below of owning and disposing of ADSs or ordinary shares, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person’s decision to acquire ADSs or ordinary shares. This discussion applies only to a U.S. Holder that holds ADSs or ordinary shares as capital assets for U.S. federal income tax purposes. In addition, it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder’s particular circumstances, including alternative minimum tax and Medicare contribution tax consequences, and tax consequences applicable to U.S. Holders subject to special rules, such as:

If an entity that is classified as a partnership for U.S. federal income tax purposes owns ADSs or ordinary shares, the U.S. federal income tax treatment of its partners will generally depend on the status of such partners and the activities of the partnership. Partnerships owning ADSs or ordinary shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of ADSs or ordinary shares.

This discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, and the income tax treaty between the United States and the PRC, or the Treaty, all as of the date hereof, any of which is subject to change, possibly with retroactive effect. This discussion is also based, in part, on representations by the Depositary and assumes that each obligation under the deposit agreement and any related agreement will be performed in accordance with its terms.

For purposes of this discussion, a “U.S. Holder” is a person that is eligible for the benefits of the Treaty, and is a beneficial owner of ADSs or ordinary shares that for U.S. federal income tax purposes is:

Treasury regulations that apply to taxable years beginning on or after December 28, 2021, or the Foreign Tax Credit Regulations, may in some circumstances prohibit a U.S. person from claiming a foreign tax credit with respect to certain non-U.S. taxes that are not creditable under applicable income tax treaties. Accordingly, U.S. investors that are not eligible for benefits under the Treaty should consult their tax advisers regarding the creditability or deductibility of any PRC taxes imposed on dividends on, or dispositions of, the ADSs or ordinary shares. This discussion does not apply to investors in this special situation.

U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of ADSs or ordinary shares in their particular circumstances.

In general, a U.S. Holder who owns ADSs will be treated as the owner of the underlying shares represented by those ADSs for U.S. federal income tax purposes. Accordingly, no gain or loss will be recognized if a U.S. Holder exchanges ADSs for the underlying shares represented by those ADSs.

Except as described in “Passive Foreign Investment Company Rules” below, this discussion assumes that we are not, and will not become, a passive foreign investment company, or PFIC.

Distributions paid on the ADSs or ordinary shares, other than certain pro rata distributions of ADSs or ordinary shares, will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as “dividends” for U.S. federal income tax purposes. Such dividends will not be eligible for the dividends-received deduction generally available to U.S. corporations under the Code. Subject to applicable limitations, dividends paid to certain non-corporate U.S. Holders may be taxable at reduced rates. Non-corporate U.S. Holders should consult their tax advisers regarding the availability of the reduced tax rate on dividends in their particular circumstances.

Dividends will be included in a U.S. Holder’s income generally on the date of the U.S. Holder’s, or in the case of ADSs, the Depositary’s, receipt. The amount of any dividend income paid in currency other than U.S. dollars will be the U.S. dollar amount calculated by reference to the spot rate in effect on the date of receipt, regardless of whether the payment is in fact converted into U.S. dollars on such date. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder generally should not be required to recognize foreign currency gain or loss in respect of the amount received. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

Dividends will be treated as foreign-source income for foreign tax credit purposes. As described in “—People’s Republic of China Taxation,” dividends paid by us may be subject to PRC withholding tax. For U.S. federal income tax purposes, the amount of the dividend income will include amounts withheld in respect of the PRC withholding tax. Subject to applicable limitations, which vary depending upon the U.S. Holder’s circumstances, PRC taxes withheld from dividend payments (at a rate not exceeding the applicable rate provided in the Treaty) generally will be creditable against a U.S. Holder’s U.S. federal income tax liability. The rules governing foreign tax credits are complex and U.S. Holders should consult their tax advisers regarding the creditability of foreign tax credits in their particular circumstances. In lieu of claiming a credit, a U.S. Holder may elect to deduct such PRC taxes in computing its taxable income, subject to applicable limitations. An election to deduct creditable foreign taxes instead of claiming foreign tax credits must apply to all creditable foreign taxes paid or accrued in the taxable year.

For U.S. federal income tax purposes, gain or loss realized on the sale or other taxable disposition of ADSs or ordinary shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the ADSs or ordinary shares for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder’s tax basis in

the ADSs or ordinary shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars.

As described in “—People’s Republic of China Taxation” above, gains on the sale of ADSs or ordinary shares may be subject to PRC taxes if we are treated as a PRC resident enterprise for PRC tax purposes. Under the Code, capital gains of U.S. persons are generally treated as U.S.-source income. However, a U.S. Holder may be able to elect to treat the gain as foreign-source income under the Treaty and claim foreign tax credit in respect to any PRC tax on dispositions. The Foreign Tax Credit Regulations generally preclude a U.S. Holder from claiming a foreign tax credit with respect to PRC income taxes on gains from dispositions of ADSs or ordinary shares if the U.S. Holder does not elect to apply the benefits of the Treaty. However, in that case it is possible that any PRC taxes on disposition gains may eitehr be deductible or reduce the amount realized on the disposition. The rules governing foreign tax credits and deductibility of foreign taxes are complex. U.S. Holders should consult their tax advisers regarding the consequences of the imposition of any PRC tax on disposition gains, including the Treaty's resourcing rule, any reporting requirements with respect to a Treaty-based return position and the creditability or deductibility of the PRC tax in their particular circumstances (including any applicable limitations).

In general, a non-U.S. corporation is a PFIC for any taxable year in which (i) 75% or more of its gross income consists of passive income or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. For purposes of the above calculations, a non-U.S. corporation that owns, directly or indirectly, at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets of the other corporation and received directly its proportionate share of the income of the other corporation. Passive income generally includes dividends, interest, rents, royalties and certain gains. Cash is a passive asset for these purposes. Based on the composition of our income and assets and the value of our assets, including goodwill, which is based on the price of the ADSs, we believe that we were not a PFIC for the 2021 taxable year and we do not expect to be a PFIC for our current taxable year. However, it is not entirely clear how the contractual arrangements between our wholly-owned PRC subsidiaries, our consolidated affiliated entities and the shareholders of our consolidated affiliated entities will be treated for purposes of the PFIC rules. Because the treatment of the contractual arrangements is not entirely clear, because we hold a substantial amount of cash, and because PFIC status depends upon the composition of our income and assets and the value of our assets from time to time (which may be determined, in part, by reference to the market price of the ADSs or ordinary shares, which could be volatile), there can be no assurance that we will not be a PFIC for our current taxable year or any future taxable year.

If we were a PFIC for any taxable year and any of our subsidiaries, consolidated affiliated entity or other companies in which we own or are treated as owning equity interests were also a PFIC (any such entity, a “Lower-tier PFIC”), U.S. Holders would be deemed to own a proportionate amount (by value) of the shares of each Lower-tier PFIC and would be subject to U.S. federal income tax according to the rules described in the subsequent paragraph on (i) certain distributions by a Lower-tier PFIC and (ii) dispositions of shares of Lower-tier PFICs, in each case as if the U.S. Holders held such shares directly, even though the U.S. Holders had not received the proceeds of those distributions or dispositions.

In general, if we were a PFIC for any taxable year during which a U.S. Holder holds ADSs or ordinary shares, gain recognized by such U.S. Holder on a sale or other disposition (including certain pledges) of its ADSs or ordinary shares would be allocated ratably over that U.S. Holder’s holding period. The amounts allocated to the taxable year of the sale or disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the resulting tax liability for each such year. Furthermore, to the extent that distributions received by a U.S. Holder in any year on its ADSs or ordinary shares exceed 125% of the average of the annual distributions on the ADSs or ordinary shares received during the preceding three taxable years or the U.S. Holder’s holding period for the ADSs or ordinary shares, whichever is shorter, such distributions would be subject to taxation in the same manner. In addition, if we were a PFIC or, with respect to particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

Alternatively, if we were a PFIC and if the ADSs were “regularly traded” on a “qualified exchange,” as defined in applicable Treasury regulations, a U.S. Holder could make a mark-to-market election that would result in tax treatment different from the general tax treatment for PFICs described in the preceding paragraph. The ADSs would be treated as “regularly traded” for any calendar year in which more than a de minimis quantity of the ADSs were traded on a qualified exchange on at least 15 days during each calendar quarter. The New York Stock Exchange, where our ADSs are listed, is a qualified exchange for this purpose. U.S. Holders will not be able to make a mark-to-market election with respect to Lower-tier PFICs, if any. Accordingly, if we were a PFIC for any taxable year, a U.S. Holder that makes the mark-to-market election may continue to be subject to the general PFIC rules with respect to such U.S. Holder’s indirect interest in any Lower-tier PFICs.

If a U.S. Holder makes the mark-to-market election, the U.S. Holder generally will recognize as ordinary income any excess of the fair market value of the ADSs at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ADSs over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. Holder makes the election, the U.S. Holder’s tax basis in the ADSs will be adjusted to reflect the income or loss amounts recognized. Any gain recognized on the sale or other disposition of ADSs in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election, with any excess treated as capital loss). If a U.S. Holder makes the mark-to-market election, distributions paid on ADSs will be treated as discussed under “—Taxation of Distributions” above.

If we are a PFIC for any taxable year during which a U.S. Holder owns ADSs or ordinary shares, we will generally continue to be treated as a PFIC with respect to the U.S. Holder for all succeeding years during which the U.S. Holder owns ADSs or ordinary shares, even if we cease to meet the threshold requirements for PFIC status.

We do not intend to provide the information that would otherwise enable U.S. Holders to make a “qualified electing fund election”, which would have resulted in alternate treatment if we were a PFIC for any taxable year.

If we were a PFIC for any taxable year during which a U.S. Holder owned any ADSs or ordinary shares, the U.S. Holder would generally be required to file annual reports with the Internal Revenue Service.

U.S. Holders should consult their tax advisers regarding the determination of whether we are a PFIC for any taxable year and the potential application of the PFIC rules to their ownership of ADSs or ordinary shares.

Payments of dividends and sales proceeds from the sale or exchange of our ADSs or ordinary shares, that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding, generally on Internal Revenue Service Form W-9. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the Internal Revenue Service.

Certain U.S. Holders who are individuals (or entities formed or availed of to hold certain “specified foreign financial assets”) may be required to report information relating to their ownership of ADSs or ordinary shares, unless the ADSs or ordinary shares are held in accounts at financial institutions (in which case the accounts may be reportable if maintained by non-U.S. financial institutions). U.S. Holders should consult their tax advisers regarding their reporting obligations with respect to the ADSs or ordinary shares.

We are subject to the periodic reporting and other informational requirements of the Exchange Act. Under the Exchange Act, we are required to file reports and other information with the SEC. Specifically, we are required to file annually a Form 20-F no later than four months after the close of each fiscal year. Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the public reference facilities maintained by the SEC at 100 F Street, N.E., Room 1580, Washington, D.C. 20549. The public may obtain information regarding the Washington, D.C. Public Reference Room by calling the SEC at 1-800-SEC-0330. The SEC also maintains a web site at www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGAR system. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act.

We will furnish The Bank of New York Mellon, the depositary of our ADSs, with our annual reports, which will include a review of operations and annual audited consolidated financial statements prepared in conformity with U.S. GAAP, and all notices of shareholders’ meetings and other reports and communications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available to holders of ADSs and, upon our request, will mail to all record holders of ADSs the information contained in any notice of a shareholders’ meeting received by the depositary from us.

Our exposure to interest rate risk primarily relates to the interest income generated by excess cash, which is mostly held in interest-bearing bank deposits. We have not used any derivative financial instruments to manage our interest risk exposure. Interest-earning instruments carry a degree of interest rate risk. We have not been exposed, nor do we anticipate being exposed, to material risks due to changes in interest rates. However, our future interest income may be lower than expected due to changes in market interest rates.

We may also be subject to interest rate risk in relation to the installment payment option that we offer to our students that enables them to finance all or part of their tuition from loans provided by third-party credit providers. The borrowing student is obligated to repay the loan principal in installments over a period ranging from three to 18 months, while we are generally obligated to pay the full amount of interest payable to the credit providers at the very beginning of the loan. We may be subject to risks associated with an increase in interest rates to the extent that we continue to agree to make the interest payments under such loans. In 2019, 2020 and 2021, our student loan coverage ratio was 70.4%, 54.9% and 24.8%, respectively. For the same periods, we made interest payments of RMB118.0 million, RMB83.3 million and RMB36.9 million (US$5.8 million), respectively, to the credit providers.

Substantially all of our revenues are denominated in Renminbi. The Renminbi is not freely convertible into foreign currencies for capital account transactions. The value of the Renminbi against the U.S. dollar and other currencies is affected by, among other things, changes in China’s political and economic conditions and China’s foreign exchange policies. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the RMB to the U.S. dollar, and the Renminbi appreciated more than 20% against the U.S. dollar over the following three years. Since June 2010, the RMB has fluctuated against the U.S. dollar, at times significantly and unpredictably. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar in the future.

To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk.

Since our inception, inflation in China has not materially impacted our results of operations. According to the National Bureau of Statistics of China, the year-over-year percent changes in the consumer price index for December 2019, 2020 and 2021 were increases of 4.5%, 0.2% and 1.5% respectively. Although we have not in the past been materially affected by inflation since our inception, we can provide no assurance that we will not be affected in the future by higher rates of inflation in China.

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may collect any of its fees by deduction from any cash distribution payable (or by selling a portion of securities or other property distributable) to ADS holders that are obligated to pay those fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

From time to time, the depositary may make payments to us to reimburse us for costs and expenses generally arising out of establishment and maintenance of the ADS program, waive fees and expenses for services provided to us by the depositary or share revenue from the fees collected from ADS holders. In performing its duties under the deposit agreement, the depositary may use brokers, dealers, foreign currency dealers or other service providers that are owned by or affiliated with the depositary and that may earn or share fees, spreads or commissions.

The depositary may convert currency itself or through any of its affiliates and, in those cases, acts as principal for its own account and not as agent, advisor, broker or fiduciary on behalf of any other person and earns revenue, including, without limitation, transaction spreads, that it will retain for its own account. The revenue is based on, among other things, the difference between the exchange rate assigned to the currency conversion made under the deposit agreement and the rate that the depositary or its affiliate receives when buying or selling foreign currency for its own account. The depositary makes no representation that the exchange rate used or obtained in any currency conversion under the deposit agreement will be the most favorable rate that could be obtained at the time or that the method by which that rate will be determined will be the most favorable to ADS holders, subject to the depositary’s obligations under the deposit agreement. The methodology used to determine exchange rates used in currency conversions is available upon request.

See “Item 10. Additional Information” for a description of the rights of shareholders, which remain unchanged.

The following “Use of Proceeds” information relates to the registration statement on Form F-1, as amended (File No. 333-223190) (the “F-1 Registration Statement”) in relation to our initial public offering of 13,000,000 ADSs representing 520,000 Class A ordinary shares, at an initial offering price of US$11.50 per ADS. Our initial public offering closed in March 2018. Goldman Sachs (Asia) L.L.C., J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC were the representatives of the underwriters.

The F-1 Registration Statement was declared effective by the SEC on March 22, 2018. The total expenses incurred for our company’s account in connection with our initial public offering was approximately US$12.8 million, which included US$10.5 million in underwriting discounts and commissions for the initial public offering and approximately US$2.3 million in other costs and expenses for our initial public offering. We received net proceeds of approximately US$176.8 million from our initial public offering and the concurrent private placements in connection with the initial public offering to DIAMOND TOWER INVESTMENTS LIMITED and ELITE CONCEPT HOLDINGS LIMITED. None of the transaction expenses included payments to directors or officers of our company or their associates, persons owning more than 10% or more of our equity securities or our affiliates. None of the net proceeds we received from the initial public offering were paid, directly or indirectly, to any of our directors or officers or their associates, persons owning 10% or more of our equity securities or our affiliates.

As of December 31, 2021, we had used a portion of the net proceeds received from our initial public offering and the concurrent private placement, which consisted of US$15 million for repurchase program and US$200.0 million for capital injection to Wuhan Zhibo, one of our wholly owned subsidiaries in China.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report, as required by Rule 13a-15(b) under the Exchange Act.

Based upon that evaluation, our management has concluded that, as of December 31, 2021, our disclosure controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act was recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. As required by Rule 13a-15(c) of the Exchange Act, our management conducted an evaluation of our company's internal control over financial reporting as of December 31, 2021 based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2021.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness of our internal control over financial reporting to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We qualified as an “emerging growth company” pursuant to the JOBS Act as of December 31, 2021. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002, in the assessment of the emerging growth company’s internal control over financial reporting. This annual report on Form 20-F does not include an attestation report of our independent registered public accounting firm.

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period covered by this annual report on Form 20-F that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

Our board of directors has determined that Mr. Yifan Li, an independent director and the chairperson of our audit committee, qualifies as an “audit committee financial expert” within the meaning of the SEC rules and possesses financial sophistication within the meaning of Listing Rules of the New York Stock Exchange. Mr. Yifan Li satisfies the “independence” requirements of Rule 10A-3 under the Securities Exchange Act of 1934, as amended, and Section 303A of the Corporate Governance Rules of the NYSE.

Our board of directors has adopted a code of business conduct and ethics that applies to all of our directors, officers, employees, including certain provisions that specifically apply to our principal executive officer, principal financial officer, principal accounting officer or controller and any other persons who perform similar functions for us. We have filed our code of business conduct and ethics as Exhibit 99.1 of our registration statement on Form F-1 (file No. 333-223190) initially filed with the SEC on February 23, 2018 and posted a copy of our code of business conduct and ethics on our website at http://www.sunlands.com/investorroom. We hereby undertake to provide to any person without charge, a copy of our code of business conduct and ethics within ten working days after we receive such person’s written request.

The following table sets forth the aggregate fees by categories specified below in connection with certain professional services rendered by Deloitte Touche Tohmatsu Certified Public Accountants LLP (PCAOB ID No. 1113), our independent registered public accounting firm, for the periods indicated.

The policy of our audit committee is to pre-approve all audit and non-audit services provided by Deloitte Touche Tohmatsu Certified Public Accountants LLP, our independent registered public accounting firm, including audit services and tax services as described above.

On December 6, 2021, our board of directors authorized a share repurchase program, under which we may repurchase up to US$15 million of Class A ordinary shares in the form of ADSs over the next 24 months. As of March 31, 2022, we had repurchased a total of 163,504 ADSs under this share repurchase program. The following table sets forth information about our purchases of outstanding ADSs from December 6, 2021 to March 31, 2022. All shares were repurchased in the open market pursuant to the share repurchase program announced on December 6, 2021.

As a Cayman Islands exempted company listed on the New York Stock Exchange, we are subject to New York Stock Exchange corporate governance listing standards. However, New York Stock Exchange rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the New York Stock Exchange corporate governance listing standards. We currently follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the New York Stock Exchange that listed companies must have: (i) a majority of independent directors; (ii) a nominating/corporate governance committee composed entirely of independent directors; and (iii) a compensation committee composed entirely of independent directors. To the extent we choose to continue to follow home country practice in the future, our shareholders may be afforded less protection than they otherwise would enjoy under New York Stock Exchange corporate governance listing standards applicable to U.S. domestic issuers. See “Item 3. Key Information—3.D. Risk Factors—Risks Relating to the ADSs—As a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the New York Stock Exchange corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with the New York Stock Exchange corporate governance listing standards.”

The consolidated financial statements of Sunlands Technology Group are included at the end of this annual report.

The registrant hereby certifies that it meets all of the requirements for filing its annual report on Form 20-F and that it has duly caused and authorized the undersigned to sign this annual report on its behalf.

We have audited the accompanying consolidated balance sheets of Sunlands Technology Group and its subsidiaries (the "Company") as of December 31, 2020 and 2021, the related consolidated statements of operations, comprehensive (loss)/income, changes in shareholders' deficit and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and Schedule I (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

Our audits also comprehended the translation of Renminbi amounts into United States dollar amounts and, in our opinion, such translation has been made in conformity with the basis stated in Note 2 to the financial statements. Such United States dollar amounts are presented solely for the convenience of readers outside the People’s Republic of China.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.
