QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS

Why am I receiving this proxy statement?

Companies are required to hold an annual shareholders’ meeting by the Nasdaq Listing Rule 5620(a). Nasdaq Listing Rules permit a foreign private issuer like us to follow the corporate governance practices of its home country pursuant to the provisions of Nasdaq Listing Rule 5615(a)(3). We have chosen to follow home country practice in place of the requirements of annual shareholders’’ meeting in lieu of Nasdaq Listing Rule 5620(a). As a Cayman Islands exempted company, we are not obliged by law or our amended and restated memorandum and articles of association to call shareholders’ annual general meetings. After this Meeting, we will hold annual general meetings or extraordinary general meetings of shareholders of the Company as needed or necessary. See “Item 16G. Corporate Governance” of the 2024 Annual Report for more information.

What is the difference between holding shares as a shareholder of record and as a beneficial owner?

Certain of our Shareholders hold their shares in an account at a brokerage firm, bank or other nominee holder, rather than holding share certificates in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.

Shareholder of Record/Registered Shareholders

If, on the Record Date, your shares were registered directly in your name with our transfer agent, Transhare Corporation, you are a “Shareholder of Record” who may vote at the Meeting, and we are sending these proxy materials directly to you. As the Shareholder of Record, you have the right to direct the voting of your shares by returning the enclosed proxy card to us or appointing your proxy via the Internet or to vote in person at the Meeting. Whether or not you plan to attend the Meeting, please read, complete, sign, date, and return the attached proxy card (or appoint your proxy via the Internet) in accordance with the instructions set out therein to ensure that your vote is counted.

Beneficial Owner

If, on the Record Date, your shares were held in an account at a brokerage firm or at a bank or other nominee holder, you are considered the beneficial owner of shares held “in street name,” and these proxy materials are being forwarded to you by your broker or nominee who is considered the Shareholder of Record for purposes of voting at the Meeting. As the beneficial owner, you have the right to direct your broker on how to vote your shares and to attend the Meeting. However, since you are not the Shareholder of Record, you may not vote these shares in person at the Meeting unless you receive a valid proxy from your brokerage firm, bank or other nominee holder. To obtain a valid proxy, you must make a special request of your brokerage firm, bank or other nominee holder. If you do not make this request, you can still vote by using the voting instruction card enclosed with this proxy statement; however, you will not be able to vote in person at the Meeting.

How do I vote?

If you were a Shareholder of Record of the Company’s Ordinary Shares on the Record Date, you may vote in person at the Meeting or by submitting a proxy. Each Ordinary Share that you own in your name entitles you to one vote on the applicable proposals.

(1) You may submit your proxy by mail or via the Internet. You may submit your proxy by mail by completing, signing and dating your proxy card and returning it in the enclosed, postage-paid and addressed envelope. You may also appoint a proxy via the Internet by following the instructions on your proxy card. If we receive your proxy card at least 24 hours prior to the Meeting and if you mark your voting instructions on the proxy card, your shares will be voted:

We encourage you to examine your proxy card closely to make sure you are voting all of your shares in the Company.

If you return a signed card, but do not provide voting instructions, your shares will be voted:

(2) You may vote in person at the Meeting. We will pass out written ballots to any Shareholder of Record who wants to vote at the Meeting.

If I plan on attending the Meeting, should I return my proxy card?

Yes. Whether or not you plan to attend the Meeting, after carefully reading and considering the information contained in this proxy statement, please complete and sign your proxy card. Then return the proxy card in the pre-addressed, postage-paid envelope provided herewith as soon as possible so your shares may be represented at the Meeting. You may also appoint a proxy via the Internet by following the instructions on your proxy card.

May I change my mind after I return my proxy?

Yes. You may revoke your proxy and change your vote at any time before the polls close at this Meeting. You may do this by:

What does it mean if I receive more than one proxy card?

You may have multiple accounts at the transfer agent and/or with brokerage firms. Please sign and return all proxy cards to ensure that all of your shares are voted.

What happens if I do not indicate how to vote my proxy?

Signed and dated proxies received by the Company without an indication of how the shareholder desires to vote on a proposal will be voted in favor of each director and proposal presented to the shareholders.

Will my shares be voted if I do not sign and return my proxy card?

If you do not sign and return your proxy card or appoint a proxy via the Internet, your shares will not be voted unless you vote in person at this Meeting.

PROPOSAL NO. 1
RATIFICATION AND APPROVAL OF THE APPOINTMENT OF THE INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

The Audit Committee has selected Marcum Asia CPAs LLP to serve as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2024 and 2025.

We are asking our shareholders to ratify the selection of Marcum Asia CPAs LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024, and approve the appointment of Marcum Asia CPAs LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025. In the event our shareholders fail to ratify or approve the appointment, the Audit Committee may reconsider this appointment.

We have been advised by Marcum Asia CPAs LLP that neither the firm nor any of its associates had any relationship during the last fiscal year with our company other than the usual relationship that exists between independent registered public accountant firms and their clients. Representatives of Marcum Asia CPAs LLP are not expected to attend the Meeting in person and therefore are not expected to be available to respond to any questions. As a result, representatives of Marcum Asia CPAs LLP will not make a statement at the Meeting.

Principal Accountant Fees and Services

The following table represents the approximate aggregate fees for services rendered by Marcum Asia CPAs LLP for the years ended December 31, 2024 and 2023, respectively:

“Audit-related fees” are the aggregate fees billed for assurance and related services that are reasonably related to the performance of the audit and are not reported under audit fees. These fees primarily include accounting consultations regarding the accounting treatment of matters that occur in the regular course of business, implications of new accounting pronouncements and other accounting issues that occur from time to time.

“Tax fees” include fees for professional services rendered by our independent registered public accounting firm for tax compliance and tax advice on actual or contemplated transactions.

“Other fees” include fees for services rendered by our independent registered public accounting firm with respect to government incentives and other matters.

The policy of our audit committee is to pre-approve all audit and non-audit services provided by our independent auditor including audit services, audit-related services, tax services and other services.

Our Audit Committee evaluated and approved in advance the scope and cost of the engagement of an auditor before the auditor rendered its audit and non-audit services.

Policies and Procedures Relating to Approval of Services by Our Independent Registered Public Accountants

The Audit Committee is solely responsible for the approval in advance of all audit and permitted non-audit services to be provided by our independent registered public accounting firms (including the fees and other terms thereof), subject to the de minimus exceptions for non-audit services provided by Section 10A(i)(1)(B) of the Exchange Act, which services are subsequently approved by the Audit Committee prior to the completion of the audit. None of the fees listed above are for services rendered pursuant to such de minimus exceptions.

The Audit Committee of our Board of Directors has established its pre-approval policies and procedures, pursuant to which the Audit Committee approved the foregoing audit, tax and non-audit services provided by Marcum Asia CPAs LLP in 2024. Consistent with the Audit Committee’s responsibility for engaging our independent auditors, all audit and permitted non-audit services require pre-approval by the Audit Committee. The full Audit Committee approves proposed services and fee estimates for these services. One or more independent directors serving on the Audit Committee may be delegated by the full Audit Committee to pre-approve any audit and non-audit services. Any such delegation shall be presented to the full Audit Committee at its next scheduled meeting. Pursuant to these procedures, the Audit Committee approved the foregoing audit services provided by Marcum Asia CPAs LLP.

Vote Required and Board Recommendation

If a quorum is present, a resolution passed by a simple majority of the votes of Ordinary Shares held by such shareholders as, being entitled to do so, vote in person or by proxy at the Meeting will be required to approve the above ratification and appointment.
