Dear Sirs,

| Re: | Legal Opinion regarding Certain Hong Kong Legal Matters

| A. | INTRODUCTION

| 1. | We, Bird and Bird, act for the Company (together with its subsidiaries, the “Group”) as its legal advisers on matters of the laws of the Hong Kong Special Administrative Region of the People’s Republic of China (“Hong Kong”) in connection with the Company’s registration statement on Form F-1 dated on or around [*] August 2025 and filed with the Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933, as amended (the “Act”) (the “Registration Statement”), relating to the Company’s resale of up to 80,161,943 Class A ordinary shares (the “Class A Ordinary Shares”) of par value US$0.00025 per share in the capital of the Company (the “Transaction”).

| 2. | This letter is limited to the laws of Hong Kong in force as at the date hereof as currently applied by the Hong Kong courts and given on the basis that they will be governed by and construed in accordance with the Hong Kong law. We express no opinion as to the laws of any other jurisdictions or as to factual matters. We have assumed that there is nothing in the laws of any other jurisdiction which affects the opinions in this opinion letter, and we have made no investigation of, and express no opinion in relation to, the laws of any other jurisdiction for the purposes of this letter. In this letter, a reference to “laws” or “law” is a reference to the common law, principles of equity and laws and regulations constituted or evidenced by documents available to the public generally.

| 3. | In giving the opinion below, we have examined only the Registration Statement and no other document, and we have relied upon the assumptions set out in paragraph ‎5 or elsewhere herein, which we have not independently verified, and the opinion is subject to the qualifications and reservations set out in paragraph ‎6 or elsewhere herein.

| B. | OPINION

| 4. | Based solely on the Registration Statement and the qualifications, assumptions and limitations set forth herein and subject to any matters not disclosed to us, and having regard to such considerations of the laws of Hong Kong in force as at the date this letter as we consider relevant, we are of the view that the description of Hong Kong laws, if any, set forth in the Registration Statement under the captions “Prospectus Summary” and “Enforceability of Civil Liabilities” in each case insofar as such statements summarize Hong Kong laws, correctly and fairly summarizes the matters referred to therein in all material respects, and nothing has been omitted from such description which would make the same misleading in any material aspect.
