The reason why children in small classes are competitive and weak may be because they are gentle, good-tempered and mature, or because they have good family education, do not compete with others, and know how to be self-respecting, confident and self-reliant. It is also possible that you are introverted and not good at communicating with people. In short, children are young and plastic, and training and education are the key. Let the child's growth be full of love and positive energy, then the child's physical and mental health will definitely become the pillar of the motherland.
