If you want to learn snacks, you must first understand snacks and know how to make snacks, which is the most basic. Then opening a store includes a series of work such as site selection, decoration, material selection and operation. You can open a shop directly if you have experience. If not, we need to study systematically and provide employment guidance. It is not difficult to learn snacks. Generally, you can master many categories in a month or so. Going to the snack bar involves a lot of service work, and there is little opportunity to learn the core technology in time.

There are many snack bars now, so the future in this area is still very good.
