The Company also requests that the Registration Statement on Form 8-A (File Number: 001-39127), under the Securities Exchange Act of 1934, as amended, covering the American depositary shares representing Class A ordinary shares of the Company (the “Registration Statement on Form 8-A,” together with the F-1 Registration Statement, the “Registration Statements”), be declared effective concurrently with the F-1 Registration Statement.

If there is any change in the acceleration request set forth above, the Company will promptly notify you of the change, in which case the Company may be making an oral request of acceleration of the effectiveness of the Registration Statements in accordance with Rule 461. Such request may be made by an executive officer of the Company or by any attorney from the Company’s U.S. counsel, Simpson Thacher & Bartlett LLP.
