First, it is children's freedom to buy snacks after selling waste products, and others have no right to interfere. Some people may think that this junior high school student in Handan, Hebei Province should buy some school supplies or give all the money to his parents after selling the waste bottles to show his children's understanding and frugality. But I don't think it's wrong for children to buy snacks with the money from selling junk. Because the money is equivalent to the money earned by children themselves, they have the right to decide how to spend the money, whether to buy snacks or stationery, or to give it to their parents. Children can choose freely.
Second, snacks are what every child yearns for, and children should not be restricted from eating snacks with the shackles of being sensible. If children are too deliberately restricted from eating snacks when they are young, they may buy snacks crazily to make up for their psychological shortcomings when they are older and have the ability to make money. Therefore, when a child has the ability to save money to buy snacks by himself, there is no need for parents to restrict him. Children don't steal or rob money, but only find a more reasonable way to make money when they are at school age. If they can persist, it is also an exercise for children. You know, when children buy snacks at first, they will not just want to buy snacks when they have more money.
Third, parents should give their children certain restrictions within the scope allowed by the department, instead of nagging everything. Parents should give their children some free space and give them some independent rights. Only with education can they be more independent. They feel that parents should give their children more self-restraint and let them decide how to save, when to sell and how to spend the money after they sell it.
