独立董事述职报告（顾晓光）
Board/Management Information Classification · 95% confidence The document is a detailed report by an independent director (顾晓光) of a company for the year 2024, describing the director's duties, attendance at board and committee meetings, communication with auditors, and oversight activities. It includes personal work history, independence confirmation, attendance records, committee participation, communication with shareholders, and evaluation of key governance and financial oversight matters. The document is titled as an "Independent Director's Work Report" for the year 2024. It is not an annual report, audit report, or earnings release, but a specific report on the independent director's duties and activities. This type of document fits best under the category of Board/Management Information (MANG), which includes announcements or reports related to company board members and senior management activities. The document length is under 5,000 characters, but it is a substantive report, not merely an announcement of a report publication. Therefore, the classification is MANG with high confidence.

监事会决议公告
Regulatory Filings Classification · 95% confidence The document is a resolution announcement from the Supervisory Board (监事会) of the company regarding the approval of various reports and proposals related to the 2024 fiscal year, including the 2024 Annual Report, financial statements, profit distribution plan, internal control report, and other related documents. It repeatedly states that the detailed reports are disclosed separately on the official information disclosure website (巨潮资讯网) and that these resolutions will be submitted to the shareholders' meeting for approval. The document itself does not contain the full annual report or detailed financial data but is a formal announcement of the Supervisory Board's meeting resolutions and approvals. The document length is short (2302 characters), and it serves as an announcement of the meeting decisions rather than the full report. Therefore, it fits best into the category of Regulatory Filings (RNS) as a general regulatory announcement and meeting resolution notice, not the Annual Report (10-K) itself or a Report Publication Announcement (RPA) because it contains substantive meeting resolution content rather than just a notice of report publication.

The document is a verification opinion on the internal control self-evaluation report, which is a type of audit or assurance report related to internal controls, not the full annual report or financial statements themselves. It is not a brief announcement or a certification letter but a detailed audit-related report on internal controls. This fits the definition of an Audit Report / Information (AR) which includes standalone audit reports and applied accounting principles. Therefore, the document should be classified as AR with high confidence.
