All schools have their own rules (规则). The rules change from one school to another. Some schools are much stricter（严格） than others. There are also some rules that are strange or funny to us. Here are some funny school rules:

Strict Japanese rules

Most schools ask students to wear uniforms, such as sports suits or skirts. But Japanese schools even have rules about the colour of underwear! They also need that girls' socks should be folded(折叠) in a certain way and boys' heads should be shaved(剃).Other Japanese schools tell students that they can't go to the movies after sunset.

Different shoes in the USA

At some American schools, students have to change their shoes when they go into the schools every day.  This makes sure students won't fall over on the floors and keeps the schools clean.

No strange hair in the UK

Students can’t have strange hairstyles in some British schools. But they can wear certain hairstyles during the World Cup years. There were two students who had special hairstyles during the 2002 World Cup. After the World Cup, their teachers asked them to go to the barber's at once.
