Shaxian snacks don't need to join. If you want to learn, you can find a snack bar that you are willing to teach! The ingredients are usually adjusted by the shop owner himself! If you remove the rental transfer fee of the pavement or something! The investment doesn't need to be too big, one or two thousand is enough! There is also the need to use the trademark Shaxian snack, to become a member of the trade association, and to sign a collective trademark license!
