Dear Mike，
How nice to hear from you！In your letter you talked about your difficulties
with your Chinese learning. Well, my advice is that first you practice speaking Chinese every day for at least 15 minutes, and listen some everyday Chinese by heart. Then, it is a must to listen to some easy tapes for 20 minutes every day, till one day you think it's time for more difficult ones. As for writing, doing simple readings as much as you can and taking some possible notes will be of much help. Besides, writing something in Chinese every day, such as keeping diaries,
will greatly improve your writing skills as well as the way you think in Chinese.
Hoping my advice will do some good to your Chinese learning.
Best wishes!
Yours，
Li Hua
