In the past, China's parents attached great importance to the "law", that is, they set rules and strict requirements for their children. Now some parents have gone to the other extreme, only emphasizing "self", blindly giving their children autonomy and freedom, and stocking them, thinking that as long as they let nature take its course, their children can grow up well. These two extremes are very one-sided. If we only emphasize the "law", it is easy to make children unhappy and have rebellious psychology. At the same time, because adults take the initiative and children are passive, children act under the supervision and control of adults, in fact, they just lose the opportunity to exercise their self-discipline ability. Once out of the supervision of adults, some children can continue to perform well because of inertia and obedience; Some children need more relaxation to balance because they have been depressed for too long or rebelled. Therefore, in many cases, such discipline may only cultivate children's endurance, concentration and adaptability, but not cultivate real self-discipline ability. And too much emphasis on giving children freedom, lavish on children, the result seems to be worse.
