Item 2 of the Statement is hereby amended and supplemented as follows: This Statement is being filed jointly pursuant to Rule 13d-1(k)(1) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), by the following persons (each, a "Reporting Person" and collectively, the "Reporting Persons"): (i) BHR Winwood; (ii) BHR Fund; and (iii) HK Praise Tourism. The Reporting Persons have entered into a joint filing agreement relating to the joint filing of the Amendment No. 2 (including any amendments thereto) in accordance with Rule 13d-1(k)(1) under the Exchange Act, a copy of which is attached as Exhibit 7.1 to the Amendment No. 2. The addresses of the principal executive offices of the Reporting Persons are: (i) BHR Winwood: Unit 2712A, 27/F, Lanbao International Center, West Dawang Road, Chaoyang District, Beijing, China; (ii) BHR Fund: Unit 2712A, 27/F, Lanbao International Center, West Dawang Road, Chaoyang District, Beijing, China; and (iii) HK Praise Tourism: Room 1607, Tower 3, Phase 1, Enterprise Square, 9 Sheung Yuet Road, Kowloon Bay, Kowloon, Hong Kong. In January 2021, certain creditors of HNA Group applied to the Higher People's Court of Hainan Province in the PRC for the restructuring of HNA Group and its subsidiaries on the ground that HNA Group and its subsidiaries are unable to repay their overdue debts and clearly lack repayment ability. In February 2021, HNA Group received a civil judgement from the Higher People's Court of Hainan Province, which ruled to accept creditors' application for the restructuring of HNA Group and its affiliates. In October 2021, debt restructuring plans (the "Restructuring Plan") of HNA Group and its subsidiaries (the "Restructuring Group") were approved by the Higher People's Court of Hainan Province. Pursuant to the Restructuring Plan, Hainan HNA No. 2 Trust Management Service Co., Ltd. ("No. 2 Trust Service") was established as a limited liability company in the PRC to provide management services to the Trust (as defined below). The controlling shareholder of No. 2 Trust Service is HNA Group Bankruptcy Reorganisation Specialised Service Trust (the "Trust"), a trust established in the PRC and created for the benefit of all the creditors of the Restructuring Group and for the implementation of the Restructuring Plan. The address of the principal offices of both No. 2 Trust Service and the Trust is 25/F, New HNA Building, No. 7 Guoxing Avenue, Melian District, Haikou, Hainan Province, China. Pursuant to the Restructuring Plan, all the assets of the Restructuring Group shall be delivered to No. 2 Trust Service for the establishment of the Trust. Therefore, as a result of the implementation of the Restructuring Plan, (i) the general partner interest and limited partner interest in BHR Fund previously held by HNA Group, through majority-owned or controlled subsidiaries, are now held by No. 2 Trust Service, through its wholly owned subsidiaries; (ii) HK Praise Tourism has become an indirectly wholly-owned subsidiary of No. 2 Trust Service; (iii) the Nominee Shareholding Agreement dated May 1, 2016 between HK Praise Tourism and Beijing Capital Airlines has been terminated, and HK Praise Tourism holds the relevant securities for its own account; and (iv) voting and disposal of Class A Ordinary Shares (including in the form of ADSs) by the Reporting Persons are subject to approval of the No. 2 Trust Service Board (as defined below) or, if the matters to be voted on are material or the amount of securities to be disposed of is significant, approval of the Management Committee (as defined below) or the Beneficiaries Meeting (as defined below), as applicable. Pursuant to the Restructuring Plan, the highest authority of the Trust is the general meeting of approximately 15,000 beneficiaries of the Trust (the "Beneficiaries Meeting"), which is entitled to decide all major matters of the Trust. The Beneficiaries Meeting is composed of all creditors of the Restructuring Group whose debts have been repaid with Trust units granted. Any resolutions presented to the Beneficiaries Meeting are subject to approval by more than half or two-thirds of the voting rights present, as applicable. No beneficiary individually is able to independently control the resolutions presented in the Beneficiaries Meeting or exert significant influence over the operation of the Trust. A management committee (the "Management Committee") is established beneath the Beneficiaries Meeting for the purpose of managing the Trust affairs according to the resolutions and authorization granted or approved in the Beneficiaries Meeting. The Management Committee is composed of 19 members, including 18 creditor representatives and one debtor representative. The members shall be elected and appointed by the Beneficiaries Meeting. Resolutions are subject to the approval of more than half or two-thirds of all members of the Management Committee, as applicable. No member of the Management Committee individually is able to control the Management Committee to make resolutions or exert significant influence over the operation of the Trust. The trustee of the Trust is a consortium formed by CITIC Trust Corporation Ltd. ("CITIC Trust") and Everbright Xinglong Trust Co., Ltd. ("Everbright Xinglong", together with CITIC Trust, the "Trustees"), both being limited liability companies established in the PRC whose principal businesses are provision of trustee services. The Trustees execute the Trust affairs according to the decision and authorization of the Beneficiaries Meeting and the Management Committee, and have no active decision-making power, and thus cannot control the Trust. The address of the principal office of CITIC Trust is 13/F, Capital Mansion, No. 6 Xinyuan South Road, Chaoyang District, Beijing, China and the address of the principal office of Everbright Xinglong is No. 555 Donggang West Road, Chengguan District, Lanzhou, Gansu Province, China. No. 2 Trust Service has a board of directors (the "No. 2 Trust Service Board") comprised of seven members nominated from the senior management team of No. 2 Trust Service and two members nominated by the Trustees. No member of the No. 2 Trust Service Board individually is able to control the No. 2 Trust Service Board to make resolutions or exert significant influence over the operation of the No. 2 Trust Service Board.
