School life in US is dangerous. You never know if the guy you just talked to had a gun in pocket. You never know if your classmate is a drug dealer or a gangster. If smoking or acting like a jerk is a sign of "cool" to a Chinese student, Tattoos, alcohol or drugs are a sign of "cool" to a student in US. You might have seen a group fight in your school, but you might have no idea what a gun fight is like.
However, students in US like sports. Asking a student who is good at maths or English, he or she is mostly likely to be have no idea; whereas, asking them who the best football, basketball, baseball players are, you will get the answers right away. Girls in US like playing soccer and going to gyms. Chinese students only like sports they are good at. They don't feel like ever playing something they are not good at. Chinese girls barely do exercises. They hate sweating. They don't think sports have anything to do with them.
A good student in China studies by doing homework and extra exercises to get themselves more familiar with more types of questions. A good student in US would be more likely to go to libraries and read books that they are interested in. They often like working on a group project or research paper. They believe that is a better way to develop problem-solving skills and it is more fun to solve a realistic problem.
