During the May 4th Movement, various ideological trends were introduced and discussed, which promoted the educational reform. A kindergarten system (Mongolian childcare system) has been established. For children aged 3-6, it is attached to the primary school attached to the women's normal school and the women's higher normal school. Kindergarten entered the school education system for the first time.

The birth of foster families in the early 20th century marked the transition of preschool education in China from family education to organized social education. The target is children aged 3 to 7 and 8. It is not set up separately, but attached to the nursery and chapel. The content of education includes games, songs, dialogues and skills, and it does not exceed four hours a day.
