Second, the listing method

Initial public offering (IPO) refers to the company's application to the securities management department in accordance with relevant laws and regulations. After examination, the securities management department meets the issuance conditions and agrees that the company can be directly listed on the securities market by issuing a certain number of public shares. Listing by shell means buying the controlling stake of a legitimate listed company (shell company) in the securities market, mastering the controlling stake of the company, and then injecting its assets and business into the shell company through asset restructuring, so that it can directly obtain the listing qualification without applying for issuing new shares.

Finally, it takes three years from planning to listing, which is still a long process. If the information prepared by the enterprise in all aspects is relatively complete or the foundation is relatively good, the time to market can be shortened accordingly.
