Dear Sir/Madam

YY INC.

We are lawyers qualified in the People’s Republic of China (the “PRC”, which, for the purpose of this opinion only, excludes the Hong Kong Special Administrative Region, the Macau Special Administrative Region and Taiwan) and are qualified to issue an opinion on PRC Laws (as defined below).

We are acting as PRC legal counsel to YY Inc. (the “Company”) solely in connection with (A) the Company’s registration statement on Form F-1 including all amendments or supplements thereto (the “Registration Statement”) filed with the Securities and Exchange Commission (the “SEC”) under the U.S. Securities Act of 1933, as amended, on October 15, 2012, relating to the initial public offering by the Company of a certain number of the Company’s American depositary shares (“ADSs”), each representing a certain number of class A common shares of par value US$0.00001 per share of the Company, and (B) the proposed listing and trading of the Company’s ADSs on the Nasdaq Global Market (the “Offering”).

1

In so acting, we have examined the Registration Statement, the originals or copies certified or otherwise identified to our satisfaction, of documents provided to us by the Company and such other documents, corporate records, certificates, approvals and other instruments as we have deemed necessary for the purpose of rendering this opinion, including, without limitation, originals or copies of the agreements and certificates issued by PRC authorities and officers of the Company (“Documents”). In such examination, we have assumed the accuracy of the factual matters described in the Registration Statement and that the Registration Statement and other documents will be executed by the parties in the forms provided to and reviewed by us. We have also assumed the genuineness of all signatures, seals and chops, the authenticity of all documents submitted to us as originals, and the conformity with the originals of all documents submitted to us as copies, and the truthfulness, accuracy and completeness of all factual statements in the documents.

Based upon and subject to the foregoing assumptions and the below qualifications, we are of the opinion that the statements set forth under the captioned “Taxation — People’s Republic of China Taxation” in the Registration Statement insofar as they constitute statement of PRC tax law, are accurate in all material respects and that such statements constitute our opinion.

We do not express any opinion herein concerning any law other than PRC tax law.

This opinion is subject to the following qualifications:

(a) This opinion relates only to any and all laws, regulations, statutes, rules, decrees, notices, and supreme court’s judicial interpretations currently in force and publicly available in the PRC as of the date hereof (“PRC Laws”) and we express no opinion as to any other laws and regulations. There is no guarantee that any of the PRC Laws, or the interpretation thereof or enforcement therefor, will not be changed, amended or replaced in the immediate future or in the longer term with or without retrospective effect.

(b) This opinion is intended to be used in the context which is specifically referred to herein and each section should be looked on as a whole regarding the same subject matter.

2

(c) This opinion is subject to the effects of (i) certain legal or statutory principles affecting the enforceability of contractual rights generally under the concepts of public interest, national security, good faith and fair dealing, applicable statutes of limitation, and the limitations by bankruptcy, insolvency, reorganization or similar laws affecting the enforcement of creditor’s rights generally; (ii) any circumstance in connection with formulation, execution or performance of any legal documents that would be deemed materially mistaken, clearly unconscionable, fraudulent; (iii) judicial discretion with respect to the availability of injunctive relief, the calculation of damages, and the entitlement of attorneys’ fees and other costs; and (iv) the discretion of any competent PRC legislative, administrative or judicial bodies in exercising their authority in connection with the interpretation, implementation and application of relevant PRC Laws.

(d) This opinion is issued based on our understanding of the current PRC Laws. For matters not explicitly provided under the current PRC Laws, the interpretation, implementation and application of the specific requirements under the PRC Laws are subject to the final discretion of competent PRC legislative, administrative and judicial authorities.

This Opinion is rendered to you for the purpose hereof only, and save as provided herein, this Opinion shall not be quoted nor shall a copy be given to any person (apart from the addressee) without our express prior written consent except where such disclosure is required to be made by the applicable law or is requested by SEC or any other regulatory agencies.

We hereby consent to the use of this opinion in, and the filing hereof as an exhibit to, the Registration Statement and to the reference to our firm under the headings “Taxation” in the Registration Statement. In giving such consent, we do not thereby admit that we fall within the category of the person whose consent is required under Section 7 of the U.S. Securities Act of 1933, as amended, or the regulations promulgated thereunder.
