Physical education class can ask for leave if she has a cold. Students who need to take time off are divided into short holidays and long holidays. Short vacation: I need to go to 1-2 class, and I feel unwell recently, such as cold and fever, minor trauma, and menstrual period for girls. Long vacation: those who need to take two vacations to go to work, or those who take leave all the year round, such as past medical history, rest after surgery, serious illness, etc.
