The listing counseling period is about 3 to 12 months, and the specific time depends on the counseling results of listed companies. Because the listing of a company is a very important matter, the sponsor institution and the China Securities Regulatory Commission should carefully check it. Therefore, the CSRC requires that listing guidance must be provided for those companies that apply for listing. Although the CSRC has not made specific requirements for the time limit for listing counseling, according to the market situation, relatively standardized listed companies have to go through three months of counseling, and the CSRC no longer makes rigid requirements for the time limit for counseling. Sponsors provide guidance to issuers of companies to be listed, and provide systematic knowledge training to directors, supervisors and senior managers of issuers, shareholders holding more than 5% of shares and actual controllers, so as to help managers of these companies fully understand and master the contents and requirements of listing and standardized operation, be familiar with these business processes, and establish the concept of honesty, trustworthiness and law-abiding when entering the securities market.
