Why is it that the child who was taken away has no life?

This may be your misunderstanding, not necessarily because he picked it up. Teenagers can be a little rebellious. If children know their own life experience, they may behave more violently than other children, but these cannot be attributed to objective reasons. You have to find responsibility from yourself. After all, you have the grace to raise children. As long as your education method is correct, you will achieve the desired effect. If there is an argument, don't be too fierce, otherwise it will hurt the child. Wait for him.
