Glad to know that you'll study in my school as an exchange: student for six months. To make your study here smoother, let me tell you something important.
Firstly, you need to be at school between: 7 30 a. m, and S: 00 p: m every day from Monday to Friday. Secondly, you'll study some regular courses, like, Chinese, Chinese history and math. Apart from these, some feature courses, like Chinese calligraphy, papercutting and Chinese kungfu will also be included. Meanwhile, you' ll have to obey our school rules. For example, you can’t come late for school or leave school earlier. If you have to, you must ask for teachers
permission. Besides, if you have any question in class, you had better raise your hand first.
Wish you to enjoy your life here!
