Parents should keep calm. Children are naughty and disobedient, and no matter how well educated they are, getting angry and hitting them won't solve the problem. Therefore, parents should first do a good job in psychological construction, because conversely, if children are too quiet and not naughty, it will actually make parents more worried.

2. The physical and mental development of children in high school has changed greatly. Although they are still underage and their minds are not perfect enough, they have a strong sense of independence and always pretend that "I am an adult", especially gradually forming their own world outlook and outlook on life.

3. Supervise the implementation. No matter how good oral education and rules are, if they are not implemented or strictly enforced, they will not be effective, and even make children feel that their parents are just talking casually and will not pay attention.
