All directors and senior management personnel of the Company ensure that there are no false records, misleading statements, or significant omissions in this report and bear individual and joint legal responsibility for the authenticity, accuracy, and completeness of the report's content. The objective of the Company's internal control is to reasonably ensure that business management is legal and compliant, assets are secure, financial reports and related information are true and complete, and to improve operational efficiency and effectiveness, thereby promoting the Company to achieve its development strategy.
