Personally, I don't agree, but all the children in my brothers and sisters' homes have started to enroll in preschool classes. I was curious and asked them, why did you report the child so young? It is a child's nature to go out to play. They replied, "Now all the children have signed up. If our own children don't sign up, it is directly lost at the starting line. " Therefore, from a rational point of view, it is worthwhile to report to the training class. After all, no one really wants their children to lose at the starting line.
