There are two ways. First, you communicate with someone who has a storefront at school and ask him to transfer the storefront to you. Second, you go to the school leaders (go to the Education Department and ask the school leaders' office) and tell them what you think. Let you know if there are any vacant stores. Be sure to pay attention to the way you speak, there are still many things to do in the supermarket. Think it over before you do it.
