I'm glad to accept your letter asking for my advices on how to learn Chinese well. Her a little suggestions. First, it important to take a Chinese course, as you can learn from the teacher and talk with your classmates. Then, it also helps to watch TV and read books and newspapers writing in Chinese. Besides, it should a good idea to learn and sing Chinese songs, so you'll learn and remember Chinese words more easy by doing so. You can also make more Chinese friends. They'll tell you a lot of about China and help you learn Chinese. Also, write me in Chinese next time.
