Dear John,
I have received your letter for several days. In your last letter you ask something about my country. So I write this letter to tell you.
My country, China, is a big country. It is my home. The family which has 13,000,000,000 populations.China is also a beautiful country. At anywhere you can see wonderful scenes. So many forigner said China is a good place to visit.
If you want to come and visit China, don't hesitate and contact me. I will try my best to make you have a good time.
Best wishes
yours
Katy
