Filing Released Lang Actions
独立董事候选人声明与承诺（于善虎）
Proxy Solicitation & Information Statement Classification · 1% confidence The document is a statement and commitment by an independent director candidate (于善虎) for election to the company’s 6th board. It sets out qualifications, disclosures and promises, which is exactly the sort of information included in proxy solicitation materials sent to shareholders in advance of a general meeting so they can vote on director nominations. This is not a full annual or interim report, not an earnings release or audit report, nor is it simply an announcement of a board change – rather it is part of the proxy/information statement package. Therefore it best fits the Proxy Solicitation & Information Statement category (PSI).

Regulatory Filings Classification · 1% confidence The document is a standalone summary table (“附表”) disclosing the company’s non-operating fund occupancy and related-party fund transactions for fiscal year 2025, including beginning and ending balances, interest, and transaction details. This is a detailed regulatory disclosure required by listing rules, but it is not a full annual or interim report, not an earnings release, not a management discussion, nor does it fit any other specific category. Therefore, it is best classified under the general “Regulatory Filings” fallback category.

It is not the full annual report or an earnings release, nor a management change or capital announcement.

It details the scheme, pricing, delivery, commitments, and governance related to the acquisition, which falls squarely under corporate M&A activity. It is not an earnings release, audit report, dividend notice, nor an announcement only; rather it is substantive transaction documentation. Therefore, it should be classified as M&A Activity (TAR).

2025年度内部控制自我评价报告
Governance Information Classification · 1% confidence The document is titled “内部控制自我评价报告” and is a detailed self-evaluation of the company’s internal control systems for the year ended December 31, 2025. It is neither an announcement (it contains the full report text) nor a financial results release, MD&A, audit opinion, nor regulatory notice. Instead, it details the company’s governance framework, internal control policies, evaluation scope, deficiency criteria, and conclusions—fitting the definition of a Governance Information report. Therefore, it should be classified under Governance Information (CGR).
