Dear David，

I'm glad you'll come to Beijing to learn Chinese.Chinese is very useful，and many foreigners are learning it now.It's difficult for you because it's quite different from English.You have to remember as many Chinese words as possible.It's also important to do some reading and writing.You can watch TV and listen to the radio to practice your listening.Do your best to talk with people in Chinese.You can learn Chinese not only from books but also from people around you.If you have any questions，please ask me.I'm sure you'll learn Chinese well.

Hope to see you soon in Beijing.

Yours，

Gao Di
