Except as disclosed in the Schedule 13D, none of the Reporting Persons has effected any transaction in the Class A Ordinary Shares during the 60 days preceding the date hereof.

Except as disclosed in the Schedule 13D, to the best knowledge of the Reporting Persons, 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 any of the Reporting Persons.

Date ownership ceased to exceed 5%

As a result of the Issuer's issuance of 79,762,048 Class A Ordinary Shares on September 24, 2026, Mr. Erqi Wang's beneficial ownership of the Class A Ordinary Shares decreased from approximately 6.77% to approximately 3.35%. Accordingly, Mr. Wang and Jolly Harmony Enterprises Limited ceased to be beneficial owners of more than five percent of the outstanding Class A Ordinary Shares on September 24, 2026. Er Pu International Limited beneficially owns 537,250 Class A Ordinary Shares, representing approximately 0.35% of the outstanding Class A Ordinary Shares, and was already the beneficial owner of less than five percent of the outstanding Class A Ordinary Shares as of the filing of the Original Schedule 13D on August 21, 2026. Accordingly, this Amendment No. 1 constitutes the final amendment to the Schedule 13D and an exit filing for each of the Reporting Persons.

Percentage of class

The responses of each Reporting Person to Rows 7 through 13 of the cover pages of this Schedule 13D are hereby incorporated by reference into this Item 5. Except as otherwise stated herein, each Reporting Person expressly disclaims any beneficial ownership of the Class A Ordinary Shares held by each other Reporting Person. Pursuant to the current report of the Issuer on Form 6-K filed on September 24, 2026, the Issuer completed the issuance of an aggregate of 79,762,048 Class A Ordinary Shares to certain third parties in connection with an acquisition transaction and related financial advisory compensation (the "Share Issuance"). As reported in the Original Schedule 13D, the Reporting Persons beneficially own, in the aggregate, 5,306,307 Class A Ordinary Shares for purposes of Rule 13d-3, consisting of (i) 4,769,057 Class B Ordinary Shares held directly by Jolly Harmony Enterprises Limited, which are convertible into Class A Ordinary Shares on a one-for-one basis, and (ii) 537,250 Class A Ordinary Shares held directly by Er Pu International Limited. Mr. Erqi Wang may be deemed to beneficially own such shares through his ownership and control of Jolly Harmony Enterprises Limited and Er Pu International Limited. The Reporting Persons did not acquire or dispose of any shares subsequent to the filing of the Original Schedule 13D on August 21, 2026. However, as a direct result of the increase in the total number of the Issuer's outstanding Class A Ordinary Shares from the Share Issuance, Mr. Wang's beneficial ownership was diluted from approximately 6.77% to approximately 3.35%, and Jolly Harmony Enterprises Limited's beneficial ownership was diluted from approximately 6.08% to approximately 3.01%. In addition, Mr. Wang's aggregate voting power was diluted from approximately 98.12% to approximately 96.15%. The percentage of beneficial ownership of Mr. Wang is calculated based on 153,425,476 Class A Ordinary Shares of the Issuer issued and outstanding as of September 24, 2026, plus 4,769,057 Class A Ordinary Shares deemed outstanding with respect to Mr. Wang pursuant to Rule 13d-3(d)(1)(i) as a result of Jolly Harmony Enterprises Limited's right to convert its 4,769,057 Class B Ordinary Shares into Class A Ordinary Shares. The percentage of beneficial ownership of Jolly Harmony Enterprises Limited is calculated based on 153,425,476 Class A Ordinary Shares issued and outstanding as of September 24, 2026, plus the 4,769,057 Class A Ordinary Shares deemed outstanding with respect to Jolly Harmony Enterprises Limited pursuant to Rule 13d-3(d)(1)(i). The percentage of beneficial ownership of Er Pu International Limited is calculated based on 153,425,476 Class A Ordinary Shares issued and outstanding as of September 24, 2026. The Class B Ordinary Shares are treated as converted into Class A Ordinary Shares only for purposes of calculating beneficial ownership pursuant to Rule 13d-3. Percentage of aggregate voting power is calculated by dividing the voting power beneficially owned by Mr. Wang by the aggregate voting power of all outstanding Class A Ordinary Shares and Class B Ordinary Shares of the Issuer as a single class. Each Class A Ordinary Share is entitled to one (1) vote, while each Class B Ordinary Share is entitled to eight hundred (800) votes on all matters submitted to a vote of shareholders. The Class A Ordinary Shares and Class B Ordinary Shares vote together as a single class on all matters submitted to a vote of shareholders, except as may otherwise be required by law or the Issuer's memorandum and articles of association.
