Key audit matters how to deal with them in the audit
The company's operating revenue in 2021 was 63380522001. We understood, evaluated and tested the company's relevant RMB related to revenue recognition, mainly the distribution revenue of electronic components, and the design and operation effectiveness of key internal control; The distribution revenue of electronic components is 56810778 million yuan. 2. By checking the sales contract and interviewing with the management, it is identified and accounted for 89.63% of the company's operating revenue. Due to the contract terms and conditions related to the transfer of control of electronic component goods, the distribution income of assessed revenue components accounts for a large proportion, and whether the operating revenue recognition policy meets the requirements of the accounting standards for business enterprises; Whether the confirmation is appropriate or not has a great impact on the operating results. There is a risk that the management manipulates the revenue recognition in order to achieve the specific operating objectives. 3. Implement the analysis procedures for the revenue, including the monthly revenue fluctuation analysis. Therefore, we take the confirmation of the distribution revenue of sub components such as the current period revenue of main electric products, the comparative analysis of gross profit margin and the previous period as the key audit procedure;

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. Based on the work we have performed, if we determine that there is a material misstatement in other information, we should report that fact. In this regard, we have nothing to report.

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 the sustainable operation ability of Shenzhen Yitoa Intelligent Control Co.Ltd(300131) company. 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 Shenzhen Yitoa Intelligent Control Co.Ltd(300131) company to be unable to continue its business.
(V) evaluate the overall presentation, 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 Shenzhen Yitoa Intelligent Control Co.Ltd(300131) company to express an opinion on the financial statements. We are responsible for guiding, supervising and executing the group audit. We are fully responsible for the audit opinion. 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.
