Filing Released Lang Actions
2025年度非经营性资金占用及其他关联资金往来情况汇总表
Regulatory Filings Classification · 1% confidence The document is a standalone Chinese disclosure table summarizing non-operating fund occupancies and other related‐party fund transactions for the full year 2025. It does not appear to be the full Annual Report or Interim Report but rather a specific regulatory disclosure schedule. It is not an announcement of a report publication, nor does it fit any specialized category such as an earnings release, call transcript, or governance document. Therefore, this miscellaneous but required regulatory filing best matches the fallback category “Regulatory Filings (RNS).”

第五届董事会第六次会议决议公告
Regulatory Filings Classification · 1% confidence The document is an official “Board of Directors Meeting Resolution Announcement” (“董事会会议决议公告”) published on CNINFO by a Shenzhen‐listed issuer. It details the convocation and resolutions passed at the company’s fifth board meeting (approval of the 2025 annual report, profit distribution plan, internal control evaluation, quarterly report, etc.) but does not announce any changes to the board composition or senior management. It is not the actual annual or quarterly report itself (no full financial disclosures, tables, or narrative beyond resolutions), nor is it a notice of dividend, proxy statement, or M&A document. Since there is no bespoke category for “board meeting resolutions,” it defaults to the general “Regulatory Filings” category (RNS).

2025年度证券投资情况的专项说明
Regulatory Filings Classification · 1% confidence The document is a special explanatory note by the Board of Hunan Sande Technology Co., Ltd. on its 2025 securities investment activities. It cites listing rules and internal control systems, provides detailed tables of portfolio transactions, and references board resolutions. It is not a full annual (10-K) or interim report, nor an earnings release, audit report, change in management, proxy statement, dividend notice, or financing announcement. It is the substantive report itself rather than an announcement of a report’s publication. This type of miscellaneous regulatory submission that doesn’t fit more specific categories is classified as a general Regulatory Filing (RNS).

关于持股5%以上股东及董事减持计划的预披露公告
Director's Dealing Classification · 1% confidence The document is an official pre-disclosure announcement by a >5% shareholder and a company director of their planned share reduction (insider sale) over a specified period, with mandatory details on share amounts, percentages, periods, legal compliance, and risk disclosures. This corresponds to insider/director share transactions rather than a corporate share repurchase or other category. Therefore, it is classified as Director’s Dealing (Code: DIRS).
