Go to Tik Tok Store Backstage-Store-Qualification Center-Industry Qualification and click "Edit"; Then delete all the previous categories and add business categories in "Modify Industry Qualification". For example, smart home, household daily use, tableware, storage and other sub-categories. You can check directly. The re-addition of this category is also conditional, and the category you add must be within the business scope of your business license! In principle, you can do whatever you want. But in general, there are many categories that are not suitable for beginners. Because the novice has just opened the store, even the basic process of Tik Tok store has not been figured out, and it is easy to destroy the store by making some complicated categories.
