If you want to open a snack bar, you must first know about snacks, and you must be able to cook snacks, which is the most basic. Then opening a shop includes a series of work such as site selection, decoration, material selection, operation, etc. If you have experience, you can open a shop directly. If you don't, if you want to develop in this area, you need to conduct systematic learning and provide employment guidance. It is not difficult to learn snacks. Generally, you can master many categories in a month or so. Going to snack bars involves a lot of service work, and there is little opportunity to learn the core technology in time. If you want to learn snacks on a zero basis, you'd better choose a regular school, and make a comprehensive comparison, including tuition fees, courses and teaching quality. There are many snack bars now, so the future in this area is still very good.
