Item 4.

Purpose of Transaction

Item 4 is hereby amended and supplemented in its entirety as follows: This Amendment No. 2 is filed to report that the Reporting Persons' aggregate percentage beneficial ownership and voting power in the Issuer was diluted as a result of the Issuer's issuance of shares as described in Item 5 below. The Reporting Persons hold the Ordinary Shares as described in this Schedule 13D/A for investment purposes. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Each Reporting Person may in the future take such actions with respect to its investment in the Issuer as it deems appropriate, including changing its current intentions, with respect to any or all matters required to be disclosed in this Schedule 13D/A, depending on various factors, including but not limited to the Issuer's business, prospects, financial position and strategic direction, price levels of the Ordinary Shares, conditions in the securities markets, and general economic and industry conditions. Consistent with the Reporting Persons' investment purposes, the Reporting Persons may engage in communications with, without limitation, one or more shareholders of the Issuer, management of the Issuer or one or more members of the board of directors of the Issuer, and may make suggestions concerning the Issuer's operations, prospects, business and financial strategies, strategic direction and transactions, assets and liabilities, business and financing alternatives and such other matters as the Reporting Person may deem relevant to their investment in the Ordinary Shares.

Except as set forth in this Item 4 or Item 6 below, the Reporting Persons have no present plans or proposals that relate to or that would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act.

Item 5.

Interest in Securities of the Issuer

(a)

The responses of the Reporting Person to Rows (7) through (13), including the footnotes thereto, of the cover pages of this Schedule 13D/A are hereby incorporated by reference in this Item 5. On December 22, 2025, the Issuer completed the issuance of 5,000,000 Class B ordinary shares to Expansion Group Ltd (the "Share Issuance"). The Reporting Persons did not acquire or dispose of any shares in this transaction and continue to beneficially own 1,225,250 ordinary shares, including 250 Class A ordinary shares and 1,225,000 Class B ordinary shares. However, as a direct result of the increase in the total number of the Issuer's outstanding shares from the Share Issuance, the Reporting Persons' aggregate beneficial ownership was diluted from approximately 7.72% to approximately 5.85%, and their aggregate voting power was diluted from approximately 46.51% to approximately 16.05%. The percentage of beneficial ownership of the Reporting Person is based on 20,935,271 ordinary shares, including 13,435,271 Class A ordinary shares and 7,500,000 Class B ordinary shares, of the Issuer outstanding as of December 22, 2025. The Class B ordinary shares are treated as converted into Class A ordinary shares only for the purpose of calculating the percentage ownership. Percentage of aggregate voting power is calculated by dividing the voting power beneficially owned by each Reporting Person by the voting power of all of our Class A ordinary shares and Class B ordinary shares as a single class. Each Class A ordinary share is entitled to one (1) vote while each Class B ordinary share is entitled to one hundred (100) votes on any and all matters submitted for a vote. Our Class A ordinary shares and Class B ordinary shares vote together as a single class on all matters submitted to a vote of our shareholders, except as may otherwise be required by law.

(b)

(c)
