CHANGE IN REGISTRANT’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

On June 15, 2021, we engaged PricewaterhouseCoopers Zhong Tian LLP (“PwC Zhong Tian”) as our independent registered public accounting firm, and dismissed PricewaterhouseCoopers (“PwC”). The change of our independent registered public accounting firm had been approved by the audit committee of our board of directors.

The reports of PwC on our consolidated financial statements for the fiscal years ended December 31, 2019 and 2020 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle.

During the fiscal years ended December 31, 2019 and 2020 and the subsequent interim period through June 15, 2021, there have been no (i) disagreements between us and PwC on any matter of accounting principles or practices, financial statement disclosure, or audit scope or procedure, which disagreements if not resolved to the satisfaction of PwC would have caused them to make reference thereto in their reports on the consolidated financial statements for such years, or (ii) reportable events as defined in Item 16F(a)(1)(v) of the instructions to Form 20-F.

We have provided PwC with a copy of the disclosures hereunder and required under Item 16F of Form 20-F and requested from PwC a letter addressed to the Securities and Exchange Commission indicating whether it agrees with such disclosures. A copy of PwC’s letter dated June 21, 2021 is attached as Exhibit 16.1 to this Form 6-K.

During each of the fiscal years ended December 31, 2019 and 2020 and the subsequent interim period through June 15, 2021, neither we nor anyone on behalf of us has consulted with PwC Zhong Tian regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, and neither a written report nor oral advice was provided to us that PwC Zhong Tian concluded was an important factor considered by us in reaching a decision as to any accounting, audit or financial reporting issue, (ii) any matter that was the subject of a disagreement pursuant to Item 16F(a)(1)(iv) of the instructions to Form 20-F, or (iii) any reportable event pursuant to Item 16F(a)(1)(v) of the instructions to Form 20-F.
