Parent-child relationship has always been an important issue in modern society! Modern society is changing rapidly. Democracy and freedom have brought about a high degree of autonomy in children, but if this autonomy is not accompanied by a sense of responsibility and respect for others, modern children's over-indulgence in autonomy will lead to problems in discipline. A child who lacks discipline will be a source of worry for his parents when he grows up. However, today's society emphasizes love education and places more emphasis on the free development of children, so the concept of discipline is also more important.
