School gate is the best seller! When I bought it, I saw that the people who sold it all used gas as raw materials! How expensive can iron plates be? . . In addition to the school gate, there are downtown areas, snack streets (places where stalls have to pay) and other places! In short, remember: the more people, the better to sell! And it is a place where there are many young people! People in their thirties and forties seldom like to eat!
