The connection of preschool education refers to the connection between preschool education and primary education. Children in kindergartens and primary schools have different physical and mental development characteristics. Solving the connection problem between preschool education and primary education is of great significance for promoting people's sustainable development and improving the quality of education.

On March 20th, 20021,the Ministry of Education issued the Guiding Opinions on Vigorously Promoting the Scientific Connection between Kindergarten and Primary School, aiming at the long-standing problems such as the disconnection between kindergarten and primary school education, weak connection consciousness, over-emphasis on knowledge preparation and imperfect connection mechanism, and put forward a series of targeted and important measures. In the autumn semester of 20021,the pilot project of young cooperation was launched, and it was fully rolled out in the autumn semester of 2022.
