hello. Let me say: 1. Because it is mobile, you can't go to industrial and commercial registration unless you set up a catering company to manage it by mobile operation and register a brand. There are some in China, such as Fanfuzi Catering Management Co., Ltd.. Therefore, the first step is to ask the industry and commerce what information to prepare. 2, because it is outdoor advertising, but also in the industry and commerce for your outdoor advertising for each car for the record. 3. In terms of the company's business scope, it should be filed with the local urban management law enforcement bureau. 4. It is best to buy vehicles that have been modified. There are already such vehicles in China. If you modify them yourself, I am afraid that you will not pass the customs in terms of vehicle management. 5. Health certificates of employees. Go to the health and epidemic prevention office. 6. Health permit. Now it has been transferred to industry and commerce, as long as it is in industry and commerce, it can be handled. If you do it as a company, these are all steps. There are many others. If you do it in the form of a company, you need to organize organization code certificate, bank account opening certificate, settlement certificate, tax registration certificate and so on. However, it will be convenient for you if you do these well. You just need to increase the number of vehicles you operate. You can also operate in a chain. Thank you for your question.
