Dividing school districts by districts refers to dividing a large education area into multiple districts according to the administrative divisions of education, and each district is equipped with one or more schools, thus forming a "district-school" corresponding allocation model of educational resources. This way can make rational use of educational resources, let students go to school nearby, reduce the burden on parents and improve the fairness and quality of education.

The advantage of dividing school districts by film lies in improving educational equity. Schools in different regions are unevenly distributed. Using the model of dividing school districts by districts, students living in districts can be enrolled nearby, which can reduce the burden of parents to send their children, increase the class size of schools and optimize educational resources. In addition, the division of school districts by film is also beneficial to education management, and it is convenient for education administrative departments and school administrators to accurately grasp children's learning situation and training needs.

Since 1980s, under the guidance of policies such as "supporting schools in urban residential areas" and "school construction planning in rural compulsory education stage", China has gradually implemented the education mode of dividing school districts. At the same time, it also explores the practice of running schools jointly between different schools and merging township primary schools and junior high schools, which makes China's education model more diversified and developed. Although there are still many problems in practice, the education system of school districts has been deeply rooted in the hearts of the people and has become an effective way to achieve educational equity and improve the quality of education.
