Does the school doctor of Wuxi No. 3 Senior High School have to be on duty?

Required.

According to the school's regulations, the school doctor is required to be on duty, but the duty system is not as strict as the hospital's duty system. This is mainly to prevent the financial situation of individual students.

Although university doctors are stipulated to be 24 hours a day, no university doctor is also on duty at night. Students who feel unwell at night during school and cannot find a school doctor have to go out of school to go to the hospital. Whether the university doctor reports 24 hours a day depends on the size of the hospital, but there should be a doctor on duty at ordinary times.
