2025年度独立董事述职报告（金雨青）
Board/Management Information Classification · 95% confidence The document is a detailed 2025 annual report by an independent director of Beijing Yitang Semiconductor Technology Co., Ltd. It includes the director's background, attendance at meetings, communication with auditors, oversight of financial reporting, internal control evaluation, and management changes during the year. It also references compliance with company law, securities law, and governance codes. The content is a comprehensive report on the independent director's duties and observations for the year 2025, which aligns with a Management Report or Management Information type document. It is not an Annual Report (10-K) as it does not contain full financial statements or comprehensive company-wide financial performance, nor is it a simple announcement or certification. It is not a Board/Management Information announcement about changes only, but a detailed report on the independent director's activities and governance oversight. Therefore, the best fitting category is Board/Management Information (MANG). The document length is 4158 characters, which is substantial for a detailed report but not a full annual report. Confidence is high given the detailed governance and management oversight content.

2025年度独立董事述职报告（JoanQiongPan）
Board/Management Information Classification · 95% confidence The document is titled '2025年度独立董事述职报告' which translates to '2025 Independent Director's Work Report'. It details the independent director's background, attendance at board and committee meetings, communication with management and shareholders, oversight of audit and internal controls, and evaluation of company governance and financial reporting. It also includes information on board and senior management changes during the year. The document is a detailed report on the independent director's activities and governance role during the year 2025. It is not an annual report, audit report, or earnings release, but rather a management/board-related report focusing on governance and director duties. Therefore, the most appropriate classification is Board/Management Information (MANG). The document length is 4202 characters, which is sufficient for a substantive report rather than a brief announcement or certification. No indication that this is a proxy statement, remuneration report, or regulatory filing. Hence, classification as MANG is appropriate with high confidence.
