holders of our ordinary shares, whether or not represented by American Depositary shares (the “ADS”), on the Record Date are
entitled to receive notice of and to vote at the Company’s annual general meeting or any adjournment or postponement thereof.
If you are a holder of our ordinary
shares on the Record Date, you are cordially invited to attend the annual general meeting in person. Your vote is important. If you cannot
attend the annual general meeting in person, you are urged to complete, sign, date and return the accompanying form of proxy by mail to

of our annual general meeting and ask you to provide your voting instructions with respect to the shares represented by your ADSs. Holders
of our ADSs who wish to exercise their voting rights for the underlying shares must act through the Depositary. For your voting instructions
to be valid, you must comply with the instructions provided by or on behalf of the Depositary, and the Depositary must receive your voting
instructions in the manner and on or before the date specified (the “ADS Voting Instructions Deadline”). Voting at the meeting
will be conducted by way of poll. In the event voting takes place at a shareholders’ meeting, the Depositary will instruct JPMorgan
Chase Bank, N.A., Hong Kong Branch, (the “Custodian”) to vote all shares in accordance with the voting instructions received.
In the event voting takes place at a shareholders’ meeting by poll, the Depositary will instruct the Custodian to vote the shares

to have instructed the Depositary to give a discretionary proxy to a person designated by the Company to vote the deposited securities
represented by the ADSs evidenced by such holder’s receipts as to which such instructions are so given, provided that no such instruction
shall be deemed given and no discretionary proxy shall be given (a) if the Company informs the Depositary in writing (and the Company
agrees to provide the Depositary with such information promptly in writing) that (i) it does not wish such proxy to be given, (ii) substantial
opposition exists with respect to any agenda item for which the proxy would be given or (iii) the agenda item in question, if approved,
would materially or adversely affect the rights of holders of shares and (b) unless, with respect to such meeting, the Depositary has
been provided with an opinion of counsel to the Company, in form and substance satisfactory to the Depositary, to the effect that (x)
the granting of such discretionary proxy does not subject the Depositary to any reporting obligations in the Cayman Islands, (y) the granting
of such proxy will not result in a violation of Cayman Islands law, rule, regulation or permit and (z) the voting arrangement and deemed
instruction as contemplated herein will be given effect under Cayman Islands law. The Depositary will not itself exercise any voting discretion.
Furthermore, neither the Depositary nor its agents are responsible for any failure to carry out any voting instructions, for the manner
in which any vote is cast or for the effect of any vote.
Our board of directors appreciates your continuing
support and urges you to support the above resolutions.
