Dasheng Global Limited, a British Virgin Islands company, is the record owner (the “Dasheng Global”) of 40,890,321 Class B ordinary shares of the Issuer. Mr. Jack Jiajia Huang is the sole director of Dasheng Global.

Dasheng Online Limited, a British Virgin Islands company, is the record owner (the “Dasheng Online”) of 17,524,423 Class B ordinary shares of the Issuer. Ms. Ting Shu is the sole director of Dasheng Online.

Each of Dasheng Global and Dasheng Online is wholly beneficially owned by Dasheng International Holdings Limited (“Dasheng Holdings”), which is in turn, wholly owned by TB Family Trust (the “Trust”), for which TMF (Cayman) Ltd. acts as the trustee (the “Trustee”). S.B. Vanwall Ltd. is the sole director of Dasheng Holdings appointed by the Trustee. The settlors of the Trust are Mr. Huang and Ms. Shu. Mr. Huang, Ms. Shu and their family members are beneficiaries under the Trust. Pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules promulgated thereunder, Dasheng Holdings, the Trust, the Trustee, Mr. Huang and Ms. Shu may be deemed to be a group, and each member of such group may be deemed to beneficially own all of the ordinary shares beneficially owned by other members constituting such group. However, each of Dasheng Holdings, the Trust, Mr. Huang and Ms. Shu disclaims beneficial ownership of any shares beneficially owned by the Trustee other than the abovementioned 40,890,321 Class B ordinary shares of the Issuer held by Dasheng Global and 17,524,423 Class B ordinary shares of the Issuer held by Dasheng Online. All shares are beneficially owned by the Trustee solely in its capacity as trustee of the Trust. Accordingly, the Trustee, solely in its capacity as trustee of the Trust, may be deemed to beneficially own all ordinary shares of the Issuer that are beneficially owned by the Trust. However, the Trustee disclaims beneficial ownership of all ordinary shares of the Issuer.

The percentage of the class of securities beneficially owned by each reporting person is based on 300,833,124 outstanding ordinary shares as a single class, being the sum of 65,064,128 Class A ordinary Shares and 235,768,996 Class B ordinary shares of the Issuer outstanding as of December 31, 2016, assuming conversion of all Class B ordinary shares into Class A ordinary shares, and excluding the 2,552,520 Class A ordinary shares issued to the Issuer’s depositary bank for bulk issuance of American depositary shares reserved for future issuances upon the exercising or vesting of awards granted under the Issuer’s share incentive plan.

Percentage of aggregate voting power represents voting power of all ordinary shares held by each Reporting Person with respect to all outstanding shares of the Issuer’s Class A and Class B ordinary shares on an as-converted basis. Each holder of the Issuer’s Class A ordinary shares is entitled to one vote per share. Each holder of the Issuer’s Class B ordinary shares is entitled to ten votes per share.
