Dear David
It is nice to hear from you. From your last letter, I heard that you would like to come to Bei Jing to learn Chinese. I am so glad that you want to learn mandarin. Here are some tips which may help you with your Chinese.
First of all, it is very helpful if you can listen to the Chinese radio channel every night, and keep it as a habit. As we all know, a language is a communication tool, one can only make an improvement by practising it frequently. Similarly, listening to the radio can be treated as a practical way to train your listening skills.
Secondly, keeping a diary in Chinese can improve one's writing skills. While you are writing a diary in Chinese, you may concur difficulties such is expression, grammer, new words and so on. After looking them up in the dictionary or other books, you can improve his writing skills largely.
Lastly, watching Chinese movies are also helpful to learn Chinese. One of the most valuable points is that you can learn and have the joy at the same time. All you have to do is to pay a little bit attention to the expression of actors. It is normal that the beginners like you may not understand the the lines in the play by only listening, hence it will be better if the movie has an Chinese-English subtitle.
I believe if you keep up the good work, you can learn Chinese well. By the way, how is your life in America? When are you coming to Beijing? I am looking forward to your reply.
