Dear David,
I’m a Chinese middle school student named Li hua. Yesterday, while surfing the internet, I saw your notice. I’m very happy to be able to become friends with you.
From your notice, I can see that you are from Canada and you want to learn Chinese language, culture and customs. I think I’m a great person to teach you about these things.
China is a great country with a long history. Not only our history but also our culture is the access to understand us better.
There are so much that you can know, if you are interested. I’ll be looking forward to your reply. I’ll show you around our great China if you come to China.
