Early childhood is an important period of life, not only the period of the fastest physical development, but also the turning point and critical period of children's rapid learning and integration into society. The process of human changing from natural person to social person is a series of socialization process, a process of learning behavior norms and social roles. In the process of children's growth and development, it is necessary to communicate with peers. As an important social relationship, peer relationship in the process of communication is inseparable from the necessary social environment. Only by fully interacting with people and things in the environment can children gradually grow from a natural person to a social person. The events and accumulated experience of children in this stage will play a certain role in children's life.
