We conducted our audit in accordance with the auditing standards for Chinese certified public accountants. The “responsibilities of certified public accountants for the audit of financial statements” in the audit report further expounds our responsibilities under these standards. In accordance with the code of professional ethics for Chinese certified public accountants, we are independent of solamet ® And fulfilled other responsibilities in terms of professional ethics. We believe that the audit evidence we have obtained is sufficient and appropriate, which provides a basis for our audit opinion.

3、 Responsibilities of management and governance for financial statements

The management is responsible for preparing the simulated financial statements in accordance with the preparation basis described in Note 2 to the simulated consolidated financial statements and the provisions of the accounting standards for business enterprises, so as to achieve a fair reflection, and design, implement and maintain necessary internal control so that the financial statements are free from material misstatement caused by fraud or error.

4、 Responsibilities of certified public accountants for the audit of financial statements

Our responsibility is to express audit opinions on the simulated financial statements on the basis of audit work. We conducted our audit in accordance with the auditing standards for Chinese certified public accountants. The auditing standards for Chinese certified public accountants require us to abide by the code of professional ethics for Chinese certified public accountants, plan and perform the audit work, so as to obtain reasonable assurance whether the simulated financial statements are free from material misstatement.

And express audit opinions on the simulated financial statements on the basis of audit work. Reasonable assurance is a high-level assurance, but it does not guarantee that the audit performed in accordance with the audit standards will always be found when a major misstatement exists. Misstatement may be caused by fraud or error. If it is reasonably expected that the misstatement alone or in summary may affect the economic decisions made by the users of the simulated financial statements based on the financial statements, the misstatement is generally considered to be significant.

In the process of carrying out the audit work in accordance with the audit standards, we use professional judgment and maintain professional doubt. At the same time, we also carry out the following work:

(1) Identify and assess the risks of material misstatement of financial statements due to fraud or error, design and implement audit procedures to deal with these risks, and obtain sufficient and appropriate audit evidence as the basis for issuing audit opinions.

Since fraud may involve collusion, forgery, intentional omission, misrepresentation or override of internal control, the risk of failing to find major misstatement caused by fraud is higher than that caused by error.

(2) Understand the internal control related to audit in order to design appropriate audit procedures, but the purpose is not to express an opinion on the effectiveness of internal control.

(3) Evaluate the appropriateness of accounting policies selected by the management and the rationality of accounting estimates and related disclosures.

(4) Draw conclusions on the appropriateness of management’s use of going concern assumptions. At the same time, according to the audit evidence obtained, it may lead to the audit of solamet ® Draw a conclusion on whether there is significant uncertainty in the matters or circumstances that have major doubts about the ability of business to continue as a going concern. If we conclude that there is significant uncertainty, the auditing standards require us to draw the attention of statement users to the relevant disclosures in the financial statements in the audit report; If the disclosure is insufficient, we should express a non unqualified opinion. Our conclusions are based on the information available as of the date of the audit report. However, future events or circumstances may lead to solamet ® The business cannot continue as a going concern.

(5) Evaluate the overall presentation, structure and content of the financial statements, and evaluate whether the financial statements fairly reflect relevant transactions and events. (6) Just solamet ® Obtain sufficient and appropriate audit evidence for the financial information of entities or business activities in business to express an audit opinion on the financial statements. We are responsible for guiding, supervising and implementing the group audit, and take full responsibility for the audit opinions.

We communicated with the management on the planned audit scope, schedule and major audit findings, including the internal control defects that we identified in the audit.

We also provide a statement to the management that we have complied with the professional ethics requirements related to independence, and communicate with the management all relationships and other matters that may reasonably be considered to affect our independence, as well as relevant preventive measures (if applicable).
