Tuoban: It is a place for children to study and play without their parents, and a place for children to participate in and adapt to collective life alone. Tuoban is suitable for babies aged 0-3. The main purpose of class is to let children enter the collective circle as soon as possible, learn how to get along with children, improve their self-care ability and prepare for entering small classes. Teachers pay attention to the cultivation of children's self-care ability in early games, and pay attention to teachers' life care and emotional care for children. Teach children to take care of themselves by playing games and singing, such as going to the toilet and washing their hands.
