Audit Report / Information Classification · 90% confidence The document is a report from Changjiang Securities Underwriting and Sponsorship Co., Ltd. regarding a continuous supervision training session conducted for Shanghai Kaixin Separation Technology Co., Ltd. in 2023.

The document is a specific report on a training event related to regulatory compliance and supervision, not a financial report, earnings release, or announcement of voting results.

Given the nature of the document as a report on continuous supervision training, it aligns best with Audit Report / Information (AR), which includes internal or regulatory compliance reports and related activities. The document length is short but contains substantive content, so it is not a mere announcement. Therefore, the classification is AR with high confidence.
