Unless a contrary intention appears, all capitalised terms used in this opinion have the respective meanings set forth in the Documents (as defined below). A reference to a Schedule is a reference to a schedule to this opinion and the headings herein are for convenience only and do not affect the construction of this opinion.

(j) the maximum number of shares which the Company is required to issue under the 2023 Equity Incentive Plan to fulfil its obligation (the ESOP Shares) will not exceed the Company’s authorised share capital then in place and the consideration payable for each ESOP Share shall be no less than the par value of the ESOP Shares; and

(k) there is nothing under any law (other than the laws of the Cayman Islands), that would or might affect the opinions herein.

3 Opinions

On the basis of the examination of the Documents and assumptions referred to above and subject to the limitations and qualifications set forth in paragraph 4 below, we are of the opinion that:

Authorised Shares

(a) Based solely on the Memorandum, the authorised share capital of the Company is US$50,000 divided into (i) 488,000,000 class A ordinary shares of a par value of USD0.0001 each and (ii) 12,000,000 class B ordinary shares of a par value of USD0.0001 each.

Valid Issuance of ESOP Shares

(b) The ESOP Shares to be issued under the 2023 Equity Incentive Plan have been duly authorised by all necessary corporate actions of the Company under the Memorandum and Articles and, upon the issuance and delivery of the ESOP Shares in accordance with the Memorandum and Articles, the Board Resolutions and the terms of the 2023 Equity Incentive Plan and once consideration of not less than the par value is fully paid per ESOP Share in accordance with the 2023 Equity Incentive Plan to the Company, the ESOP Shares will be validly issued, fully paid and non-assessable. Once the register of members of the Company has been updated to reflect the issuance of the ESOP Shares, the shareholders recorded in the register of members of the Company will be deemed to have legal title to the shares of the Company set out against their respective name.

(a) as to any laws other than the laws of the Cayman Islands, and we have not, for the purposes of this opinion, made any investigation of the laws of any other jurisdiction, and we express no opinion as to the meaning, validity, or effect of references in the 2023 Equity Incentive Plan to statutes, rules, regulations, codes or judicial authority of any jurisdiction other than the Cayman Islands; or

(b) except to the extent that this opinion expressly provides otherwise, as to the commercial terms of, or the validity, enforceability or effect of the Form S-8, the accuracy of representations, the fulfilment of warranties or conditions, the occurrence of events of default or terminating events or the existence of any conflicts or inconsistencies among the Form S-8 and any other agreements into which the Company may have entered or any other documents.

(a) governed by, and shall be construed in accordance with, the laws of the Cayman Islands;
