        <footnote id="F2">The term &quot;RMB Shares&quot; is used herein to represent the ordinary shares, par value $0.0001 per share, of the Issuer, issued directly by the Issuer in the Issuer's initial public offering on the Science and Technology Innovation Board (the &quot;STAR Market&quot;) of the Shanghai Stock Exchange (the &quot;STAR Offering&quot;), to permitted investors in Renminbi (&quot;RMB&quot;) within the People's Republic of China (&quot;PRC&quot;) in accordance with the rules of the STAR Market.</footnote>
        <footnote id="F3">The Issuer established an employee participation program (&quot;RMB Shares Employee Participation Plan&quot;), which allows certain executive officers and qualified employees of the Issuer's subsidiaries in the PRC to indirectly participate in the STAR Offering and purchase certain RMB Shares from the Issuer through an asset management plan administrated by China International Capital Corporation Limited in a transaction that is exempt under Rule 16b-3. The RMB Share Employee Participation Plan purchased an aggregate of 2,069,546 RMB Shares directly from the Issuer in the STAR Offering at the initial public offering price of RMB192.6 per RMB Share (or $30.1295 based on an assumed exchange rate of $1.00 = RMB6.3924).</footnote>
        <footnote id="F4">The Reporting Person, as an individual participant in the RMB Shares Employee Participation Plan, has contributed RMB10 million to the RMB Shares Employee Participation Plan. The Reporting Person may be deemed to have indirect economic interest in an indeterminable portion of the RMB Shares held by the RMB Shares Employee Participation Plan but does not have voting or dispositive power over any of such shares. The Reporting Person disclaims Section 16 beneficial ownership of the RMB Shares held by the RMB Shares Employee Participation Plan, except to the extent, if any, of his pecuniary interest therein. This report shall not be deemed an admission that the Reporting Person is the beneficial owner of such RMB Shares for Section 16 or any other purpose.</footnote>
