2025年年度独立董事述职报告（余爱水）
Board/Management Information Classification · 95% confidence The document is titled as an "Independent Director's Annual Report" for the year 2025 by an independent director of Shenzhen Yinghe Technology Co., Ltd. It details the director's duties, attendance at board and committee meetings, oversight activities, communication with auditors, and evaluation of company governance and financial reporting. The content focuses on the independent director's role and activities during the year, including review of financial reports and internal controls, but it is not a full annual report or financial statement itself. It is a formal report by an independent director on their annual duties and observations, which is a type of management or board-related information. This fits best under the category of Board/Management Information (MANG), as it relates to board member activities and governance oversight rather than a full annual report or audit report. The document length (6684 characters) and detailed content support it being a substantive report rather than a brief announcement or certification. Therefore, the classification is MANG with high confidence.

2025年年度独立董事述职报告（张玉兰）
Board/Management Information Classification · 95% confidence The document is titled as an "Independent Director's Annual Report" for the year 2025 by an independent director of Shenzhen Yinghe Technology Co., Ltd. It details the director's background, attendance at board and committee meetings, exercise of duties, communication with auditors, supervision of governance and financial reporting, and other related activities during the year. The content focuses on the independent director's duties, oversight, and compliance with laws and regulations, rather than presenting financial statements or audit results. It is a detailed report on board/management information, specifically the independent director's annual work report. It is not an annual report (10-K), audit report, or regulatory filing. Therefore, the most appropriate classification is Board/Management Information (MANG). The document length (6531 characters) supports it being a full report rather than a brief announcement or certification.

关于调整限制性股票回购价格及回购注销部分激励对象已获授但尚未解除限售的限制性股票的公告
Transaction in Own Shares Classification · 95% confidence The document is an official announcement from Shenzhen Yinghe Technology Co., Ltd. regarding adjustments to the repurchase price of restricted stocks and the repurchase and cancellation of certain restricted stocks granted but not yet released from sale restrictions. It details board and shareholder meeting approvals, legal opinions, stock repurchase quantities, prices, and effects on share capital structure. The content focuses on share repurchase activities related to stock incentives, including legal compliance and procedural approvals. There are no financial statements or earnings data, nor is it a report or presentation. The document is a formal announcement about the company's repurchase of its own shares (restricted stock) and related adjustments. Therefore, it fits the category of Transaction in Own Shares (POS). The document length is 4302 characters, which is sufficient for a detailed announcement rather than a brief notice or report publication announcement.

关于2025年度计提资产减值准备及核销资产的公告
Regulatory Filings Classification · 95% confidence The document is a detailed announcement from Shenzhen Yinghe Technology Co., Ltd. regarding the provision for asset impairment and write-off of assets for the fiscal year 2025. It includes specific financial figures for impairment provisions, accounting policies, and the impact on the company's financials. The document is 4436 characters long, which is relatively short but contains substantive financial data and detailed accounting explanations rather than merely announcing the publication of a report. It is not a full annual or interim report but a specific financial disclosure about asset impairment provisions. This type of document fits best under the category of Regulatory Filings (RNS) because it is a regulatory announcement about asset impairment provisions and write-offs, not a full audit report or annual report. It is not a certification or a brief announcement but a detailed regulatory disclosure. Therefore, the appropriate classification is Regulatory Filings (RNS).

第五届董事会第二十六次会议决议的公告
Regulatory Filings Classification · 95% confidence The document is an announcement of resolutions passed at a board meeting of Shenzhen Yinghe Technology Co., Ltd. It details the approval of various reports and proposals such as the 2025 Annual Report, Board Work Report, ESG Report, Internal Control Self-Evaluation Report, and others. However, the actual reports are referenced as being published separately on the CNINFO website, indicating this document is not the reports themselves but an announcement of the board's decisions regarding these reports. The document length is 4475 characters, which is relatively short and consistent with an announcement rather than a full report. The content focuses on board meeting resolutions and approvals, not the full financial or operational details of the reports. Therefore, this document fits best into the category of Regulatory Filings (RNS) as a general regulatory announcement of board meeting resolutions and report approvals, rather than the reports themselves or other more specific categories.

关于购买董高责任险的公告
Regulatory Filings Classification · 95% confidence The document is an announcement regarding the company's decision to purchase Directors and Officers (D&O) liability insurance. It includes details about the insurance coverage, premium, and authorization for management to handle related matters. The document is short (842 characters) and serves as a formal announcement rather than a detailed report or financial statement. It does not contain financial results, management discussion, or regulatory certifications. It is not a report publication announcement since it does not mention any report being published or attached. The content fits best under a general regulatory announcement category related to corporate governance and risk management disclosures but does not fit into more specific categories like Board/Management Information (which is for changes in personnel) or Remuneration Information. Therefore, the most appropriate classification is Regulatory Filings (RNS), which is the fallback for miscellaneous regulatory announcements that do not fit other categories.
