The advantage of charity sale is to do good deeds and improve your popularity. The disadvantage is that the quality and price of products are not well controlled, which will attract people's abuse.

Pupils must be careful not to sell their own useful things. You need to learn these things next, so be careful not to sell your useful things. A charity sale is selling things you don't need. A great man once said, "It is not enough for people to have rich food and nutrition." I believe my child will grow up in such a healthy learning environment, he will be more excellent and his child's tomorrow will be more exciting.

First of all, the main point of primary school students' charity sale is not to let others cheat you, because you have charity sale and I have many bad people. Because you are a child, you cheat you and even use force, so first of all, you should protect yourself with your brain.
