Keji can make mistakes by tapping his back with a newspaper roll. Just to let him know that he is wrong. Education should pay attention to ways and means, which can be beaten, but not abused. Beating will only make it afraid of you and lose trust. Maybe one day it will start to resist when it thinks it can beat you. What's wrong with Keji? If Keji makes a mistake, he can pat him on the back with a newspaper roll to let him know that he is wrong. Education should pay attention to ways and means, which can be beaten, but not abused.
