This Schedule 13D is being filed by Tsang Hing Sze (the “Reporting Person”) and is being filed because the Reporting Person may be deemed to have a formed a “group” with certain other persons, as described in Item 4 herein.

The business address for the Reporting Person and CruiSo is Unit B, 18/F, MG Tower, 133 Hoi Bun Road, Kwun Tong, Hong Kong S.A.R. The Reporting Person is a citizen of Hong Kong S.A.R.

Except as expressly otherwise stated herein, the Reporting Person expressly disclaims beneficial ownership for all purposes of the Ordinary Shares (including Ordinary Shares represented by ADSs) beneficially owned by any other person (including any other Rollover Shareholder, as defined in Item 4). Information with respect to the Reporting Person is given solely by such Reporting Person, and the Reporting Person does not assume responsibility for the accuracy or completeness of the information concerning any other person.

(d) – (e)

During the last five years the Reporting Person has not: (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and, as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

The information set forth in Item 4 of this Schedule 13D is incorporated herein by reference in its entirety.

Item 4. Purpose of Transaction.

On November 24, 2023, the Issuer announced in a press release that it had entered into an Agreement and Plan of Merger (the “Merger Agreement”) with TSH Investment Holding Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands (“Parent”) and TSH Merger Sub Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands and a wholly-owned subsidiary of Parent (“Merger Sub”), pursuant to which, and subject to the terms and conditions thereof, Merger Sub will merge with and into the Issuer, with the Issuer continuing as the surviving company and becoming a wholly-owned subsidiary of Parent (the “Merger”).

Concurrently with the execution of the Merger Agreement, Parent, the Reporting Person and the other shareholders party thereto (collectively with the Reporting Person, the “Rollover Shareholders”) executed a support agreement (the “Support Agreement”), pursuant to which, each of the Rollover Shareholders has agreed to, subject to the terms and conditions set forth therein and among other obligations, (i) the cancellation of the shares held by such Rollover Shareholders for no cash consideration, (ii) subscribe for newly issued ordinary shares of Parent immediately prior to the closing of the Merger, (iii) vote in favor of authorization and approval of the Merger Agreement and the transactions contemplated by the Merger Agreement (the “Transactions”), including the Merger; and (iv) against any proposals or actions inconsistent or interfering with the Transactions.

The purpose of the Transactions, including the Merger, is to acquire all of the shares of the Ordinary Shares held by shareholders of the Issuer other than the Rollover Shares. Following consummation of the Merger, the Issuer will become a wholly-owned subsidiary of the Parent. In addition, if the Merger is consummated, the Issuer will be privately-held by the other Rollover Shareholders and its ADSs will no longer be listed on the Nasdaq Global Market.

The information disclosed in this Item 4 does not purport to be complete and is qualified in its entirety by references to the Merger Agreement and the Support Agreement, a copy of each which is filed as Exhibits 99.1 and 99.2, respectively, and incorporated herein by reference in its entirety.

The information set forth in paragraph (a) – (c) (f) of Item 2 of this Schedule 13D is incorporated herein by reference in its entirety.

Except as described above, the Reporting Person has no plans or proposals which relate to or would result in any of the actions specified in paragraphs (a) through (j) of Item 4 of Schedule 13D. The Reporting Person may, at any time and from time to time, formulate other purposes, plans or proposals regarding the Issuer, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

(a) – (b) The response of the Reporting Person to Rows (7) through (13), including the footnotes thereto, of the cover pages of this Schedule 13D are hereby incorporated by reference in this Item 5.

As a result of entering into the Support Agreement, the Reporting Person may be deemed to be the member of a “group” with the other Rollover Shareholders pursuant to Section 13(d) of the Exchange Act. However, the Reporting Person expressly disclaims beneficial ownership of the Ordinary Shares (including Ordinary Shares represented by ADSs) beneficially owned (or deemed to be beneficially owned) by any of the other Rollover Shareholders. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that the Reporting Person beneficially owns any Ordinary Shares (including Ordinary Shares represented by ADSs) that are beneficially owned (or deemed to be beneficially owned) by any of the other Rollover Shareholders.

Collectively, the “group” may be deemed to beneficially own 17,589,131 Class A Ordinary Shares, comprised of an aggregate of (a) 13,107,568 Class A Ordinary Shares; (b) 4,385,078 Class A Ordinary Shares issuable upon the conversion of 4,385,078 Class B Ordinary Shares; and (c) 96,485 Class A Ordinary Shares issuable upon the exercise of options, held by the Rollover Shareholders. This total does not include 27,905 Class A Ordinary shares that are issuable upon the exercise of options and 164,990 Class A Ordinary Shares that are issuable upon vesting of

restricted stock units, held by the Rollover Shareholders, that cannot be exercised or vest, respectively, within 60 days. This represents approximately 36% of the total outstanding Class A Ordinary Shares, assuming that there is a total of 48,958,919 Class A Ordinary Shares outstanding, which includes: (i) the 44,477,356 Class A Ordinary Shares outstanding as of November 24, 2023, as specified in the Merger Agreement filed by the Issuer with the SEC on November 24, 2023; (ii) 4,385,078 Class A Ordinary Shares issuable upon the conversion of the Class B Ordinary Shares held by the Rollover Shareholders; and (iii) 96,485 Class A Ordinary Shares issuable upon the exercise of options held by the Rollover Shareholders.

(c) Except as disclosed in this Schedule 13D, the Reporting Person has not effected any transaction in the Class A Ordinary Shares during the 60 days preceding the date hereof.

(d) Except as disclosed in this Schedule 13D, to the best knowledge of the Reporting Person, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Class A Ordinary Shares beneficially owned by the Reporting Person.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

The disclosure under Item 4 is incorporated herein by reference in its entirety.

To the best knowledge of the Reporting Person, except as provided herein, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Person and any other person with respect to any securities of the Issuer, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, divisions of profits or loss, or the giving or withholding of proxies, or a pledge or contingency, the occurrence of which would give another person voting power over the securities of the Issuer.
