Most students in China have their own school rules. So do the schools in other countries.
Japan: Most schools demand(要求) that students wear uniforms, such as sports suits or skirts. They also demand that girls’ white socks be folded in a certain way and boys’ heads be shaved(剃)
Other Japanese schools tell students that they may not date, go to movies, leave home after sunset or play video games without permission from school.
USA: For safety at home USA schools, students must have a pair of indoor shoes to change into at school every day. This makes sure students won’t fall over on the slippery floors and keeps the schools clean. Gum chewing is not allowed in many USA school buildings, as it is difficult to clean up. And if students chew gum in class, they may not focus on study.
UK: Strange hairstyles are not allowed in some British schools. But they might allow students to wear certain hairstyles during the World Cup years. Two students had a special design shaved into their hair during 2002 World Cup. But they were not accepted by their school after that because the school said the rules changed since then.
