Apart form assisting students in establishing a sense of belongings to school, school uniform can also guarantee security at school. If students do not have to wear school uniform, anyone can enter the school freely and security will be in doubt. On the other hand, if students of a school require wearing school uniform, they can be distinguished between students of other school as well as trespassers. By virtue of wearing school uniform, unnecessary commotion and burglary can be utterly avoided.
School uniform also serves as a constraint on students’ misbehavior outside school. When students are wearing school uniforms, they may avoid misbehavior that will ruin the reputation of the school, such as smoking and shoplifting. Students in school uniforms are also forbidden to go to video game centres. It is not uncommon that triad members and gangsters hunt for preys at the centres, thereby, to a certain extent; school uniform can wall away gangsters from students.
