Item 3 is hereby amended and supplemented in its entirety as follows: The information set forth in Item 4 and Item 6 is hereby incorporated by reference into this Item 3. On May 21, 2025, the Issuer effected a 1-for-400 reverse share split (the "Reverse Split"). Following the Reverse Split, every four hundred (400) issued and authorized Class A and Class B ordinary shares of a par value of US$0.001 each were consolidated into one (1) Class A or Class B ordinary share, respectively, with a par value of US$0.4 per share. On July 7, 2025, the Issuer entered into a Securities Purchase Agreement (the "Agreement") with certain institutional investors (the "Investors"). Pursuant to the Agreement, on July 23, 2025 (the "Closing Date"), the Issuer issued and sold to the Investors an aggregate of 10,000,000 Class A ordinary shares, par value $0.40 per share (the "Class A Ordinary Shares"), at a purchase price of $3.156 per share (the "Share Issuance"). Concurrently with the Share Issuance, the Issuer issued to the Investors a warrant (the "Warrant") to purchase up to an aggregate of 20,000,000 additional Class A Ordinary Shares. The Warrant is exercisable in two equal tranches: 50% of the Warrant are exercisable at 200% of the per share purchase price, and the remaining 50% are exercisable at 250% of the per share purchase price. Following the Reverse Split and Share Issuance, the Reporting Persons beneficially own 250 Class A ordinary shares and 1,225,000 Class B ordinary shares of the Issuer, representing approximately 7.72% of the Issuer's total outstanding shares and 46.51% of its total voting power. None of the Reporting Persons has effected any transactions in the Issuer's ordinary shares in the past 60 days. The reported change in beneficial ownership and voting power of the Reporting Persons was solely due to the Reverse Split and dilution from the Share Issuance.

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. The Reporting Person expects that they will, from time to time, review their investment position in the Issuer and may make additional purchases of Ordinary Shares (or other securities convertible or exercisable into Ordinary Shares) in the open market or in privately negotiated transactions, or hold or dispose of all or part of their investments in the Ordinary Shares, depending upon the Reporting Persons' evaluation of the Issuer's business, prospects, financial condition and strategic direction, the market for the Ordinary Shares, other opportunities available to the Reporting Persons, general economic conditions, stock market conditions and other factors.
