Affected by the decline in the birth population and the concentration of population in urban areas, the number of primary schools in China has rapidly decreased. Data from the Ministry of Education shows that the number of regular primary schools nationwide has decreased by about 29,700 in five years. Many places have begun to revitalize and utilize idle rural primary and secondary school buildings, converting them into facilities such as elderly care service centers, highlighting the background of accelerating low birth rates and aging population.
