First of all, we should think about whether parents' demands are reasonable. Don't force your children to do things they don't want to do. If others force you to do something they don't want to do, you will also show disobedience.
Secondly, learn to respect children and don't talk to them in a commanding tone. This is hard for rebellious children to accept. We should try to discuss with him and ask him if he can do it, not what you will do for me.
Of course, there are also basic rules. Principles still can't make children rebel, such as safety and conduct. Let him know what he can't do and what the consequences are.
