The policy stipulates that when the number of qualified applicants in a school district exceeds the enrollment plan of the school, the school should enroll students in a certain order according to the household registration and family housing situation of school-age children and the principle of "household consistency".

In other words, children in a school district can have two schools to choose from.

Starting from 17, Xiacheng District of Hangzhou implemented the "university district system" for registered students in some schools.

In addition to local registered students, the children of migrant workers in some parts of the northern part of Xiacheng District also implement the "university district system"

Students with regional household registration in a university can apply for one of the two universities in Zuanze on their own according to the principle of proximity. If the number of applicants exceeds the enrollment plan, the district education bureau will make overall arrangements and interpret the children's reading problems according to the principle of relative proximity.

At present, there are at least four urban districts in Hangzhou, namely Shangcheng District, Xiacheng District, Binjiang District and Gongshu District, which adopt the "dual-district system", involving more than 20 public primary schools (including nine-year compulsory schools).
