Following the repurchase, the Issuer allotted and issued to Jolly Harmony 3,769,057 Class B Ordinary Shares at an issue price of US$1.641 per share, for aggregate consideration of US$6,185,022.54. Each Class B share was immediately convertible into one Class A share and therefore is being reported as beneficial ownership of Class A shares pursuant to Rule 13d-3(d)(1). The subscription price was funded with the proceeds received by Jolly Harmony from the substantially contemporaneous repurchase. No borrowed funds were used. Before these transactions, Jolly Harmony held 3,769,057 Class A Ordinary Shares and 1,000,000 Class B Ordinary Shares. Following the transactions, Jolly Harmony held 4,769,057 Class B Ordinary Shares and no Class A Ordinary Shares. Er Pu International Limited continued to hold 537,250 Class A Ordinary Shares. The information set forth in or incorporated by reference into Item 3 of this Schedule 13D is hereby incorporated by reference in its entirety into this Item 4.

(the "Acquisition"), pursuant to which the Issuer expects to issue a substantial number of additional Class A Ordinary Shares. In connection with these transactions, the Issuer repurchased from Jolly Harmony 3,769,057 Class A Ordinary Shares and subsequently allotted and issued to Jolly Harmony the same number of Class B Ordinary Shares. The purpose of these transactions was to preserve continuity in the ownership and voting control of the Issuer by Mr. Erqi Wang following the issuance of additional Class A Ordinary Shares in connection with the Acquisition. Each Class B Ordinary Share held by Jolly Harmony is entitled to 800 votes per share and is convertible, at the option of its holder, into one Class A Ordinary Share.
