School-age children should have the official permanent residence of the family in the teaching area, and their household registration should be in the same household registration place as their parents (or their legal guardians) in principle, and the household registration should be consistent with the actual permanent residence and property certificate (property certificate refers to the house ownership certificate, and the holder is the legal guardian of school-age children).

Public primary schools are admitted to the nearest school without examination according to the teaching area. Parents (or their legal guardians) of school-age children in the teaching area should go through the registration formalities for freshmen according to the specified date. At the time of registration, parents (or their legal guardians) and school-age children's household registration book, real estate license, vaccination certificate and other relevant documents must be issued. If the registration formalities are not completed within the time limit, the district education bureau will coordinate and solve them.
