On. What is the most important course for international students when they arrive in school? Needless to say, it must be a course to learn Chinese! International students who are new to Chinese for the first time feel very excited and speak in class very enthusiastically. Finally, after the teacher ’s hard work and correction, everyone finally learned to say "How are you?" And "Thank you" before the end of the class. I hope everyone can always be so interested in Chinese!
