Each of Dasheng Global, Dasheng Online and Dasheng Holdings is a British Virgin Islands company. Mr. Huang is the sole director of Dasheng Global, and Ms. Shu is the sole director of Dasheng Online. Each of Dasheng Global and Dasheng Online is wholly beneficially owned by Dasheng Holdings, which is in turn wholly owned by the Trust, for which TMF (Cayman) Ltd. acts as the trustee (the “Trustee”).

Mr. Huang, Ms. Shu and their family members are beneficiaries under the Trust. Pursuant to Section 13(d) of the Exchange Act, and the rules promulgated thereunder, Dasheng Holdings, the Trust, the Trustee, Mr. Huang and Ms. Shu may be deemed to be a group, and each member of such group may be deemed to beneficially own all of the ordinary shares beneficially owned by other members constituting such group. All shares beneficially owned by the Trust are beneficially owned by the Trustee solely in its capacity as trustee of the Trust. Accordingly, the Trustee, solely in its capacity as trustee of the Trust, may be deemed to beneficially own all ordinary shares of the Issuer that are beneficially owned by the Trust. However, the Trustee disclaims beneficial ownership of all ordinary shares of the Issuer.

(4) The percentage of voting power is calculated by dividing the voting power beneficially owned by the reporting person by the voting power of all of the Issuer’s holders of Class A ordinary shares and Class B ordinary shares as a single class as of February 29, 2024 (taking into account the number of shares that the reporting person had the right to acquire within 60 days the date hereof). Each holder of Class A ordinary shares is entitled to one vote per share and each holder of Class B ordinary shares is entitled to ten votes per share on all matters submitted to them for a vote.

Class B ordinary shares are convertible at any time by the holder thereof into Class A ordinary shares on a one-for-one basis.
