Item 4. Purpose of Transaction

Item 4 of the Original Filing is hereby amended and supplemented by adding at the end thereof the following:

On October 11, 2022, the Company and Merger Sub filed a plan of merger with the Registrar of Companies of the Cayman Islands, pursuant to which the Merger became effective on October 11, 2022. As a result of the Merger, the Company became a wholly-owned subsidiary of Parent.

At the effective time of the Merger (the “Effective Time”), (a) each Ordinary Share issued and outstanding immediately prior to the Effective Time (other than the Excluded Shares (as defined below), the Dissenting Shares (as defined below) and Class A Ordinary Shares represented by ADSs) was cancelled and ceased to exist in exchange for the right to receive $0.1357 in cash per Ordinary Share without interest and net of any applicable withholding taxes and (b) each ADS issued and outstanding immediately prior to the Effective Time (other than ADSs representing Excluded Shares), was cancelled and ceased to exist in exchange for the right to receive $1.90 in cash per ADS (less applicable fees, charges and expenses payable by ADS holders), without interest and net of any applicable withholding taxes.

The “Excluded Shares” are, collectively, (a) the Rollover Shares contributed prior to the closing of the Merger in exchange for newly issued ordinary shares of Parent, including the IDG Rollover Shares contributed pursuant to the IDG Rollover Agreement, (b) any other Ordinary Shares (including Class A Ordinary Shares represented by ADSs) held by Parent, Merger Sub, the Company or any of their respective subsidiaries, which were cancelled and ceased to exist for nil consideration or distribution therefor and (c) any other Ordinary Shares (including Class A Ordinary Shares represented by ADSs) held by the depositary of the Company’s ADS program and reserved for issuance, settlement and allocation upon exercise or vesting of the Company’s options, which were cancelled and ceased to exist for nil consideration or distribution therefor. The “Dissenting Shares” refer to all Ordinary Shares owned by holders who have validly delivered and not effectively withdrawn or lost their rights to dissent from the Merger, or dissenter rights, in accordance with Section 238 of the Companies Act of the Cayman Islands.

As a result of the Merger, the ADSs ceased to trade on the OTC Market prior to the opening of trading on October 12, 2022 and became eligible for delisting from the OTC Market and termination of registration pursuant to Section 12(g)(4) of the Act.

As a result of these transactions, the Reporting Persons no longer beneficially own any Ordinary Shares.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Original Filing is hereby amended and restated in its entirety as follows:

(a)-(b) As a result of the Merger, as described in Item 4 of this Schedule 13D, the Reporting Persons do not beneficially own any Ordinary Shares or have any voting power or dispositive power over any Ordinary Shares.

(c) Except as set forth in Item 4 of this Schedule 13D, to the knowledge of each of the Reporting Persons, none of the Reporting Persons has effected any transactions in the Ordinary Shares during the past 60 days.

(d) Not applicable.

(e) October 11, 2022.
