You can open a snack bar. First of all, you should have an understanding of snacks, and you should be able to make snacks, which is the most basic. Then opening a shop includes a series of work such as site selection, decoration, material selection and operation. If you have experience, you can open a shop directly. If you don't, you need to carry out systematic study and create 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.
