The Ministry of Education reminds parents of primary and secondary school students that their school status is unified throughout the country and unique for life, and the vouchers go with everyone, regardless of public or private. The student status system is serious and the student status management is strict. Repeated registration is not allowed, and schools are not allowed to accept students who have no school status or no school status. When students transfer to other provinces, parents must provide information such as name, ID number and official or temporary national student number to the transferred school, so that the transferred school can initiate online transfer. Among them, the national student number should be transferred from the school for inquiry.
