The percentage of the class of securities beneficially owned by each reporting person is calculated based on a total of 337,395,390 issued and outstanding ordinary shares (consisting of 288,434,474 Class A ordinary shares and 48,960,916 Class B ordinary shares) of the Company as of December 31, 2022 as a single class. In computing the percentage ownership of the reporting persons, we have included, where applicable, shares that the reporting persons have the right to acquire within 60 days, including through the exercise of any option, warrant, or other right or the conversion of any other security, after December 31, 2022.

As of December 31, 2022, Ziyu Shen held 100% of the issued and outstanding shares of Jie&Hao Holding Limited, which in turn held 24,480,458 Class B ordinary shares of the Company. Jie&Hao Holding Limited is a British Virgin Islands company.

For each reporting person, percentage of aggregate voting power is calculated by dividing the voting power beneficially owned by such reporting person by the voting power of all of the Company’s Class A ordinary shares and Class B ordinary shares as a single class. Each Class B ordinary share is entitled to ten votes per share, whereas each Class A ordinary share is entitled to one vote per share
