第二届监事会第十六次会议决议的公告
Board/Management Information Classification · 95% confidence The document is an announcement of the resolutions passed at the 16th meeting of the second Supervisory Board of the company. It includes details about the meeting, voting results, and references to other reports such as the 2025 third quarter report and amendments to the company charter. The document does not contain the full third quarter report itself but refers to it being disclosed elsewhere. It also discusses governance changes and proposals to be submitted to the shareholders' meeting. The document is a formal announcement of board/management decisions and meeting resolutions rather than a full financial report or regulatory filing. Therefore, it fits best under Board/Management Information (MANG). The document length is short and it is not the report itself but an announcement of meeting resolutions and governance changes.

对外投资管理制度（2025年10月）
Governance Information Classification · 95% confidence The document is titled '对外投资管理制度' which translates to 'External Investment Management System' and details the company's policies, procedures, and governance related to external investments. It includes sections on investment decision-making, implementation, management, financial management, auditing, personnel management, and information disclosure. There is no indication that this is a financial report such as an annual or interim report, earnings release, or audit report. It is a detailed internal policy document related to governance and management practices. It does not announce or summarize financial results or contain financial statements. It is not a brief announcement or a presentation. The document is a governance-related policy document issued by the company board and approved by the shareholders. Therefore, the most appropriate classification is Governance Information (CGR). The document length (4942 characters) and content support this classification with high confidence.

Governance Information Classification · 95% confidence The document is titled as an "Independent Director Annual Report Work System" for a company, detailing the duties, responsibilities, and procedures for independent directors in relation to the company's annual report preparation and disclosure. It references laws and regulations related to securities and corporate governance, and outlines the process for independent directors to review, supervise, and report on the annual report. However, the document itself is a governance policy or internal procedural document rather than the annual report or audit report itself. It does not contain financial data or audit results but rather describes the framework for independent directors' involvement in the annual report process. Therefore, it fits best under Governance Information (CGR), which covers reports detailing the company's internal rules, board structure, and governance practices.
