Board/Management Information Classification · 1% confidence The document is a public statement and commitment by a shareholder (佛山市南华仪器股份有限公司) nominating a candidate for the company’s 6th Board of Directors as an independent director. It details qualifications, compliance checks, and formal commitments. This is clearly about board/management changes (nominating and appointing an independent director) rather than financial results, dividends, or regulatory filings.

Governance Information Classification · 1% confidence The document is a special report by the board on the self-examination of the independence of its independent directors under CSRC and Shenzhen Stock Exchange governance rules.
