I just graduated ... the school stipulates that I must wear school uniform every week 1, 2, 4 and 5; Three, six, whatever. In addition, you must wear winter clothes or summer clothes on Tuesdays, and you can wear formal clothes at other times. As far as I know, the three grades are the same. Except for Tuesday's school meeting, teachers don't care much about school uniforms. People who manage school uniforms mainly manage themselves. Who says no, self-management people stand in two rows at the entrance of the dormitory every morning because they are full? Isn't it just grabbing school uniforms and badges?
