Except as specifically provided herein, this Amendment No. 20 does not modify any of the information previously reported in the Schedule 13D as supplemented and amended by Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4, Amendment No. 5, Amendment No. 6, Amendment No. 7, Amendment No. 8, Amendment No. 9, Amendment No. 10, Amendment No. 11, Amendment No. 12, Amendment No. 13, Amendment No. 14, Amendment No. 15, Amendment No. 16, Amendment No. 17, Amendment No. 18, and Amendment No. 19. Capitalized terms used herein shall have the meaning ascribed to them in the Schedule 13D, unless otherwise defined herein.

This Amendment is being filed as a result of the change in the number of the Issuer’s outstanding Class A Shares as reported by the Issuer on its Amendment no. 1 to Form F-3 Registration Statement filed on September 1, 2021 and not as a result of any transactions in the Issuer’s shares by the Reporting Persons.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a) The aggregate number of Class A Shares and the percentage of total outstanding Class A Shares beneficially owned by the Reporting Persons is set forth below. References to percentage ownerships of Class A Shares in this Statement are based upon the 726,102,640 Class A Shares outstanding as of September 1, 2021 based on information provided to the Reporting Persons by the Issuer. TU International is the record holder of the Shares except for 827,356 ADSs purchased through TU Capital’s direct wholly-owned subsidiary Unis Technology Strategy Investment Limited (“Unis”). The filing of this Statement shall not be construed as an admission that a Reporting Person beneficially owns shares held by any other Reporting Person.

TU International beneficially owns the Shares, except for 827,356 ADSs purchased through TU Capital’s direct wholly-owned subsidiary Unis, which represents approximately 18.16% of the outstanding Class A Shares calculated in accordance with the requirements of Rule 13d-3 under the Act.

TU Capital, as the direct parent company of TU International, may also be deemed to beneficially own the Shares which in aggregate represent approximately 19.30% of the outstanding Class A Shares calculated in accordance with the requirements of Rule 13d-3 under the Act.

TU, as an indirect, but controlling, parent company of TU International, and direct parent company of TU Capital, may also be deemed to beneficially own all of the Shares.

Zhao Weiguo, who is the Chairman of the Board of TU and a director of each of TU Capital and TU International and in such capacity possesses the decision making power of TU, TU Capital, and TU International with respect to the voting and disposition of securities beneficially owned and as a result may also be deemed to beneficially own the Shares.

By virtue of the relationship described herein, the Reporting Persons may be deemed to constitute a “group” for purposes of Rule 13(d)(3) of the Act. As a member of a group, each Reporting Person may be deemed to share voting and dispositive power with respect to, and as a result beneficially own, the Shares beneficially owned by members of the group as a whole. The filing of this Statement shall not be construed as an admission that a Reporting Person beneficially owns those Shares held by any other member of the group. In addition, each Reporting Person expressly disclaims beneficial ownership of any securities reported herein except to the extent such Reporting Person actually exercises voting or dispositive power with respect to such securities.

(b) Each of TU, TU Capital, TU International and Zhao Weiguo may be deemed to have shared power to vote and dispose or direct the vote and direct the disposition of the Shares with the exception that TU International does not have shared power to vote and dispose or direct the vote and direct the disposition of the ADSs purchased indirectly by TU Capital through Unis.

(c) The Reporting Persons have affected no transactions in the Shares in the past 60 days.

(d) Not applicable.

(e) Not applicable.
