Preschool education is a multi-faceted training process. Attention to preschool children's mental health should not be underestimated. Children of this age are extremely immature in mental development and need the active guidance of parents and kindergarten teachers.

Therefore, as parents and kindergarten teachers, we should actively guide children to learn to care about others, learn to share and be willing to share.
