Is it filial for parents to rummage through their children's schoolbags and children to scold their parents for being neurotic?

In this case, both sides made mistakes. It is wrong for parents to invade their children's privacy. However, parents may also do this out of protection for their children, fearing that they will not tell them if they have done something bad. The child's fault is not telling his parents anything. This makes parents want to know their children in this way. The two sides sat down and communicated well. Nothing is difficult to solve.
