I think it's better to open a bookstore, mainly dealing in books (get in touch with the teachers in the school and ask them to recommend students to buy from you). How to do it, you know), and then sell some stationery, or snacks, popsicles or something To get a good business license, the main business is books, and other things can only be sold along with it. Don't pretend to be the owner. This should make you a little more money than opening a stationery store. Ha ha.
