Dear David,
I'm glad you're going to Beijing to learn Chinese. Every year，there are (million)of foreigners coming to China to learn Chinese. China is one of the greatest (country)in the world and Chinese is becoming more and more (use).Many foreigners are learning now. But it may be more difficult for foreigners to learn Chinese，because it's different English. As a language，Chinese is getting as (important)as English. So I think it's also a new challenge(挑战)for you. If you want to learn it (good), you should study harder before. Remember to listen to the radio to practise your listening. It's a good idea to catch every chance(机会)to talk in Chinese. It's important (do)some reading and writing. If you have any (question)，please ask me. I'm sure you'll make it.
Hope to see you soon in Beijing！
Yours,
Li Ping
