Schools may not require students to participate in unified education and teaching activities in advance. For individual students who arrive at school in advance due to special family circumstances, the school should open the door in advance and make proper arrangements. Reasonable arrangement of recess and afternoon class time, places and schools where conditions permit should ensure students' necessary lunch break; Boarding schools should arrange their work and rest schedules reasonably to ensure that students meet the prescribed sleep time requirements.
