Dear Lucy,
From your last letter I know you meet with difficulties in learning
Chinese .But you mustn't worry about it .If you try hard ,you'll surely make
great progresses .Here are some advice for you .Firstly ,you should make
less efforts to pronounce Chinese chracters correct .Secondly ,you
should find more Chinese people to talk with so that you can get some
improving .In addition ,don't forget to prepare for a Chinese dictionary,
because it can help you learn Chinese unless there's nobody to teach
you .Cheer up or I'm sure your efforts will one day pay off
Looking forward to see you.
Best wishes!
Yours,
Li Hua
