Our audit opinion on the financial statements does not cover other information, and we will not issue any form of assurance conclusion on other information.

In combination with our audit of the financial statements, our responsibility is to read other information and consider whether other information is materially inconsistent with the financial statements or the information we have learned in the audit process, or there seems to be material misstatement.

When preparing the financial statements, the management is responsible for assessing the going concern ability of Emtek (Shenzhen) Co.Ltd(300938) the company, disclosing the matters related to going concern (if applicable), and applying the going concern assumption, unless liquidation is planned, operation is terminated or there is no other realistic choice.

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

Our goal is to obtain reasonable assurance on whether the financial statements as a whole are free from material misstatement due to fraud or error, and issue an audit report containing audit opinions. 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 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:

(I) 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.

(II) understand the internal control related to audit in order to design appropriate audit procedures, but the purpose is not to express opinions on the effectiveness of internal control.

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

(IV) draw a conclusion on the appropriateness of the management's use of the going concern assumption. At the same time, according to the audit evidence obtained, draw a conclusion on whether there are major uncertainties in the matters or circumstances that may lead to major doubts about Emtek (Shenzhen) Co.Ltd(300938) going concern ability. 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 cause Emtek (Shenzhen) Co.Ltd(300938) unable to continue its business.

(V) evaluate the overall presentation (including disclosure), structure and content of the financial statements, and evaluate whether the financial statements fairly reflect relevant transactions and events.

(VI) obtain sufficient and appropriate audit evidence on the financial information of entities or business activities in Emtek (Shenzhen) Co.Ltd(300938) to express audit opinions on the consolidated 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).

From the matters communicated with the management, we determine which matters are the most important for the audit of the current financial statements, thus constituting key audit matters. We describe these matters in the audit report, unless laws and regulations prohibit the public disclosure of these matters, or in rare cases, if the negative consequences of communicating a matter in the audit report are reasonably expected to exceed the benefits in the public interest, we determine that we should not communicate the matter in the audit report.
