独立董事述职报告（黄亚钧）
Management Reports Classification · 95% confidence The document is titled as an "Independent Director's Work Report" for the year 2021 by an independent director of the company. It details the director's attendance at board meetings, opinions on various company matters, committee roles, investigations, investor protection efforts, and training. The content is a detailed report on the director's activities and responsibilities during the year, not an announcement or a brief summary. It does not contain financial statements or earnings data, so it is not an Annual Report (10-K) or Interim Report (IR). It is not a proxy solicitation, voting result, or remuneration report. The document fits best as a Management Report (MDA) because it provides management-level explanation and oversight activities related to governance and company operations from the perspective of an independent director. The document length is under 5,000 characters but contains substantive content, so it is not a mere announcement (RPA). Therefore, the classification is MDA with high confidence.

Board/Management Information Classification · 95% confidence The document is a detailed announcement of the resolutions passed at the fourth meeting of the third board of directors of Shanghai Kaixin Separation Technology Co., Ltd. It includes multiple agenda items such as approval of the 2021 annual board work report, general manager's work report, 2021 annual report and its summary, 2021 financial final accounts report, profit distribution plan, internal control self-evaluation report, special reports on fundraising and related party transactions, reappointment of auditors, 2022 director and senior management remuneration plans, revisions to company bylaws and governance rules, and approval of the 2022 first quarter report. The document also references that these reports and announcements are published separately on the official disclosure platform (cninfo.com.cn) with specific announcement numbers. The document is a formal board meeting resolution announcement, not the reports themselves. It is comprehensive and over 8,000 characters, but it primarily records board decisions and approvals rather than containing the full financial statements or detailed report content. Therefore, it is best classified as Board/Management Information (MANG) because it announces board meeting resolutions including management reports and governance matters, but does not itself contain the full annual report or interim report. The references to other reports being published separately confirm this is a board meeting resolution announcement rather than the reports themselves.
