Dear David
I am very happy that you will come to China to learn chinese. Chinese is very useful, and many foreigners are learning. It's difficult for you because it's quite different from English. You have to remember as many Chinese words. It is also important to do some reading and writing. You can watch TV, listen to the radio to practice your listening. Do your best to talk with people in chinese. You can learn Chinese, learn not only from books, but also from people around you. If you have any question, please tell me. I'm sure you will learn chinese. Hope to see you in Dongguan.
You
