2024年度董事会工作报告
Management Reports Classification · 95% confidence The document is titled as the "2024年度董事会工作报告" (2024 Annual Board Work Report) of Shenzhen Tefa Information Co., Ltd. It contains detailed descriptions of the company's business operations, financial performance, board activities, committee reports, and future outlook for the year 2024. The content includes comprehensive management discussion and analysis of business segments, financial results, strategic plans, and governance activities. It is a detailed report from the board of directors covering the full fiscal year 2024, which aligns with the characteristics of a Management Report (MDA). It is not a full Annual Report (10-K) as it lacks full audited financial statements and comprehensive financial disclosures typical of an annual report. It is also not a simple announcement or certification, nor a transcript or presentation. The length and detail confirm it is a substantive management report from the board.

2024年度独立董事述职报告（张昭宇离任）
Board/Management Information Classification · 95% confidence The document is a detailed annual report by an independent director of Shenzhen Special Information Co., Ltd. It outlines the director's duties, attendance at meetings, committee participation, review of financial reports, and overall evaluation for the year 2024. The content focuses on governance, compliance with laws and regulations, and the director's role in overseeing company operations and protecting shareholder interests. It is not a full annual report of financial performance but a specific report on the independent director's duties and activities for the year. This type of document fits best under Board/Management Information (MANG), as it relates to management and board-level reporting rather than financial results or audit reports. The document length is 4335 characters, which is substantial and contains detailed narrative rather than just an announcement or certification, so it is not RPA or RNS. Therefore, the classification is MANG with high confidence.

Audit Report / Information Classification · 95% confidence The document is a report from the Board Audit Committee regarding the supervision of the accounting firm for the 2024 fiscal year. It details the audit firm's qualifications, the procedures for their appointment, and the committee's oversight activities related to the audit of the company's 2024 financial report and internal controls. The document does not contain the actual financial statements or audit results but rather discusses the supervisory process and evaluation of the auditor's performance. This fits the definition of an Audit Report / Information (AR), which includes standalone audit reports and information about audit processes and applied accounting principles, excluding full annual reports. The document length is under 5,000 characters and is a detailed report, not merely an announcement or certification, so it is not RPA or RNS. Therefore, the correct classification is AR with high confidence. FY 2024
