(4) Disclosure of financial information in financial accounting reports and periodic reports, and internal control evaluation reports

I believe that the financial information in the company's financial accounting reports and periodic reports truly, accurately and completely reflects the actual situation of the company, and there are no false records, misleading statements or major omissions.

In addition, the company has completed the construction and evaluation of the internal control system in accordance with the requirements of the "Basic Standards for Enterprise Internal Control" and its supporting guidelines, and organized and implemented it in accordance with the "Company Internal Control Management Manual". I believe that the content and form of the internal control evaluation report disclosed by the company during my tenure are in compliance with relevant regulations and objectively, truly and accurately reflect the current internal control status of the company. The external audit institution Zhongqin Wanxin Accounting Firm (Special General Partnership) audited the effectiveness of the company's internal control over financial reporting and believed that the company maintained effective internal control over financial reporting in all material aspects.

During his tenure, the company held the fourth meeting of the fifth board of directors and the 2024 annual shareholders (general meeting), and reviewed and approved the "Proposal on Renewal of the Company's Audit Institution for 2025". After verification, I believe that Zhongqin Wanxin Certified Public Accountants (Special General Partnership) was able to follow independent, objective and fair practice standards, carry out audit work conscientiously and solidly, and complete various audit tasks well during the company's 2024 special audit and financial statement audit. I agree to re-appoint Zhongqin Wanxin Certified Public Accountants (Special General Partnership) as the company's auditor for 2025, and agree to submit it to the company's 2024 annual shareholders (general meeting) for review.

The company held the fourth meeting of the fifth board of directors on April 16, 2025, and reviewed and approved the "Proposal on Changes in Accounting Estimates." After verification, I believe that this change in accounting estimates will more objectively and fairly reflect the company's financial status and operating results, and is more in line with relevant laws, regulations and "Accounting Standards for Business Enterprises No. 28 - Accounting Policies, Accounting Estimate Changes and Error Corrections" and other provisions, and will not harm the interests of the company and all shareholders, especially small and medium-sized shareholders.

All directors abstained from voting on the "Proposal on the Remuneration Plan for Directors and Senior Management Personnel" and directly submitted it to the company's 2024 annual shareholders' (general) meeting for review. I believe that this decision-making process complies with the requirements of the "Shanghai Stock Exchange Stock Listing Rules" and "Code of Governance of Listed Companies" and other regulations, and the board of directors' review procedures are legal and effective.

During the reporting period, the company did not implement equity incentive measures such as equity incentive plans and employee stock ownership plans.

4. Overall evaluation and suggestions

In 2025, as an independent director of the company, I strictly followed the requirements of relevant laws and regulations, and with a responsible attitude towards the company and all shareholders, actively investigated and carefully analyzed the company's production and operating conditions through various methods, attended the company's board of directors and shareholders (general) meetings on time, carefully studied the relevant proposals that need to be reviewed by the board of directors, and exercised my voting rights in a prudent and responsible manner, which played a positive role in promoting the scientific decision-making of the board of directors, promoting the company's standardized operations, and safeguarding the legitimate rights and interests of the company and all shareholders. I and the other three independent directors conducted self-evaluations and mutual evaluations on the performance of their duties in 2025, and the evaluation results were all competent.

In 2026, I will continue to perform my duties as an independent director independently, impartially, prudently, conscientiously, diligently and faithfully, and rely on my professional knowledge and experience to provide the company with more positive and effective opinions and suggestions, promote the continuous improvement of the company's scientific decision-making level, and effectively safeguard the overall interests of the company and the legitimate rights and interests of small and medium-sized shareholders.
