Filing Released Lang Actions
2025年度独立董事述职报告（冯晓）
Governance Information Classification · 1% confidence The document is the annual work report by an independent director describing governance activities, board/committee attendance, audit oversight, and compliance with regulatory governance rules. It is not an announcement of a board change (MANG) nor a financial results report (10-K, IR, ER, MDA), but a governance report detailing board structure and processes. Thus, it best fits Governance Information (CGR).

董事会审计委员会对会计师事务所2025年度履职情况评估及履行监督职责情况的报告
Audit Report / Information Classification · 1% confidence The document is a formal report issued by the company’s Board Audit Committee on its evaluation of the external auditor’s performance and its own oversight activities for the 2025 audit. It is not the company’s full annual report, earnings release, or management discussion, nor is it merely an announcement of a report publication. Instead, it provides standalone audit-related information on the auditor’s credentials, audit scope, independence assessment, procedures performed, and conclusions. This fits the “Audit Report / Information” category, which covers standalone audit reports and related audit information separate from the full annual report.

杭州长川科技股份有限公司关于续聘天健会计师事务所（特殊普通合伙）为公司2026年度审计机构的公告
Regulatory Filings Classification · 1% confidence The document is an official announcement by Hangzhou Changchuan Technology Co., Ltd. regarding the reappointment of Tianjian Accounting Firm as its 2026 audit institution. It does not contain the actual audited financial statements or an audit opinion (which would be classified as an Audit Report), but rather notifies investors of the auditor selection and related governance approvals. There is no fitting specific category for an auditor‐appointment notice, so it falls into the general regulatory announcement fallback category.

It is not the annual report itself, nor the publication of the report, but notification of an upcoming investor presentation event. Thus, it best fits the Investor Presentation category (Code: IP).
