In the process of raising funds publicly, it is necessary to record and record the entrustment process synchronously. According to relevant data, the CBRC issued the Interim Provisions on the Management of Audio and Video Recordings in the Sales Zone of Banking Financial Institutions, in order to standardize the sales market order and the sales behavior of banking financial institutions' own wealth management products and consignment products, and to solve the problems of misleading sales and private sales of flight orders. China Banking Regulatory Commission explicitly requires banking financial institutions to implement double recording in special zones, that is, to set up a sales zone and assemble an electronic system in the sales zone to synchronously record and video the sales process of their own wealth management products and consignment products.
