The smooth, scientific and standardized development of the early childhood-primary interface cannot be achieved without the effective linkage and cooperation of the government, community, family, elementary school and kindergarten. In the process of constructing a multi-body linkage mechanism, there are still dilemmas such as the government's dominance has not yet been highlighted, the community's enthusiasm needs to be enhanced, the family's participation is obviously insufficient, and the linkage mechanism of early childhood and elementary school has not been formed. In order to ensure the smooth construction of the linkage mechanism, we should give full play to the leading responsibility of the educational administration, use community resources to serve the scientific EYFS, mobilize parents to participate in EYFS activities, and promote the collaborative efforts of EYFS to ensure the two-way nature of the linkage.
