  To further enhance the quality of listed companies, protect the legitimate rights and interests of investors, and maintain the order of the securities market, the China Securities Regulatory Commission (CSRC) issued the Notice on Implementing the Work Plan for Promoting Random Sampling (CSRC Announcement [2015] No. 80) in accordance with policy documents including the Notice of the General Office of the State Council on Promoting Random Sampling to Regulate Mid-Event and Post-Event Supervision (Guo Ban Fa [2015] No. 58). Since 2016, CSRC has implemented on-site inspection and random sampling of listed companies, requiring various provinces and cities with independent planning status to conduct random sampling to strengthen preventive regulation.
