As a junior high school student, there are lots of rules you need to obey. I will tell you something about these.
Firstly, you must go to school on time. You mustn't wear special clothes, it's against the rules. And you can't talk loudly in the class. But you can speak after you raise your hand.
Above all, you should work hard, it's the most important.
I hope you can enjoy your school life.
