Schools should give children plenty of physical activities, instead of locking children in classrooms and occupying physical education class for various reasons.
After school, they have enough time and energy to do what they like and develop their own personality, instead of this remedial class, that piano music class or a lot of homework, so that children can't get up.
The best way is that teachers are willing to put down their posture, treat children equally, and guide children to find answers themselves, instead of obeying the so-called absolute authority.
