Legal analysis: "73 1 policy" refers to the "Implementation Opinions on Admission to Compulsory Education in 2020 in Xicheng District" issued by Xicheng District Education Committee in April last year. The "Opinions" clearly pointed out that school-age children who bought houses in Xicheng District after July 3, 2020 and obtained the property right certificate to apply for primary school will no longer enter school, and all of them will be enrolled in the school district or adjacent school districts by multi-school dicing.

Legal basis: Beijing Xicheng District Education Commission's Implementation Opinions on Compulsory Education Admission in Xicheng District in 2020. Since 2020, Xicheng District has recorded the registered addresses and schools of school-age children. In principle, only one registered degree will be provided within six years from the year when the real estate address is used for registration (except those that meet the national birth policy). After the degree is occupied, when the school-age children living at the address enter school within six years, they will no longer enroll in the school, and all of them will enroll in the school district or adjacent school districts by multi-school dicing.
