Hainan needs closed management before and after school starts. First, the duty system will continue to be implemented before the start of school, and the campus will be closed. Without approval, students are not allowed to return to school in advance. All school facilities are temporarily closed to the public, and indoor venues such as school libraries, gymnasiums and student activity centers are closed.

Second, after the start of school, all kindergartens in primary and secondary schools are under closed management. It is strictly forbidden for outsiders to enter the campus. Teachers and students must verify their identity and check their body temperature when they enter the school. The campus is managed by districts, the canteen of the student activity center of the library gymnasium is restricted, and the student dormitory is closed. Real-name verification and temperature detection are required in and out. Kindergartens in primary and secondary schools should take the initiative to connect with the health department, do a good job in school prevention and control, strictly implement the epidemic monitoring system, refine the prevention and control measures, organize class teachers and other teachers to take man-to-man measures, fully grasp the daily health status of students, and do a good job in registering their body temperature twice a day and leaving early. If teachers and students are found to have suspicious symptoms, they should be immediately isolated and reported to the epidemic management personnel in time, and actively cooperate with the health and medical departments to manage and disinfect close contacts to prevent the spread of the epidemic on campus.
