Share Issue/Capital Change Classification · 95% confidence The document is an official announcement from Ningbo Changyang Technology Co., Ltd. regarding the listing and circulation of restricted shares issued to specific investors. It details the number of shares becoming tradable, the lock-up period, shareholder commitments, and regulatory approvals. The text includes specific dates, share quantities, and references to regulatory compliance and shareholder commitments.

Board/Management Information Classification · 95% confidence The document is an independent director's annual performance report for the year 2024, detailing the director's duties, attendance, committee participation, and oversight activities. It is a narrative report on governance and director responsibilities rather than a financial report, audit, or regulatory filing. It does not contain financial statements or earnings data, nor is it an announcement of a report publication. The content aligns with a management or board-related report focusing on director duties and governance oversight. Therefore, the most appropriate classification is Board/Management Information (MANG). The document length is under 5,000 characters, but it is a substantive report, not a mere announcement or certification, so it is not RPA or RNS.

Governance Information Classification · 95% confidence The document is a special report from the board of directors assessing the independence of the company's independent directors, referencing regulatory guidelines related to independent directors and their independence. It is a specific governance-related report about board members' independence, not a general annual report, audit report, or financial statement. It does not announce voting results, changes in management, or financial results. The content fits best under governance-related information about board practices and compliance with independence rules. Therefore, the document is classified as Governance Information (CGR). The document length is short but contains substantive content, not just an announcement or certification, so it is not RPA or RNS.

Audit Report / Information Classification · 95% confidence The document is a report from the Audit Committee regarding the performance and supervision of the external audit firm (立信会计师事务所) for the fiscal year 2024.

The document does not contain the full annual report or financial statements but focuses on the audit firm's oversight and audit quality assessment. This matches the definition of an Audit Report / Information (AR), which includes standalone audit reports and results of internal or regulatory audits, excluding the full Annual Report (10-K). The document length is 2101 characters, which is relatively short but contains substantive audit-related content rather than just an announcement or certification. Therefore, the appropriate classification is AR with high confidence. FY 2024

This type of document fits best under Regulatory Filings (RNS) as it is a compliance and disclosure document related to corporate governance and regulatory requirements, but not a full report or announcement of voting results or management changes.
