Legal analysis: it is necessary to apply for a license (catering generally has three certificates: business license, hygiene license and sewage permit), so it is necessary to have a fixed business place (the biggest premise). However, it is said that some cities in China have specially issued relevant systems and documents for mobile vendors so that they can legally apply for business licenses. You can consult the industrial and commercial bureau, food and drug administration (or health bureau) and environmental protection bureau in your jurisdiction.

Legal basis: Article 35 of the Measures for the Administration of Registration of Sole proprietorship enterprises. Anyone who engages in business activities in the name of sole proprietorship without the approval and registration of the registration authority according to law shall be ordered by the registration authority to stop business activities and be fined not more than 3,000 yuan.
