What if the little boy doesn't listen to his father?

In fact, the key point has been pointed out in your question. A father can't let go of his face and communicate with his son. Because of work, the intimate relationship between father and son has never been established. It can be said that the son has no complete trust in his father, so he will be disobedient and unable to speak. Therefore, a father might as well get along with his son not as a discipline, but as a friend to participate in the children's life and entertainment. For example, the father lets the children play alone and do something to cultivate the intimacy between father and son. Talk about education after establishing intimate relationship, otherwise it may get twice the result with half the effort and make the relationship between father and son more tense.
