Dear Teddy,

I am glad to hear that you will come to China. You’ve told me that you are very interested in ancient Chinese cultural relics, especially the Great Wall. Now, I will give you a brief introduction to the Great Wall. The Great Wall is located in the northern part of China, the length of which is about 6,700 kilometers. In 1987, it was added to the World Heritage list. The Great Wall was originally built in the Qin Dynasty to defend against the attack of the enemies. The Great wall is a wonder that was created by the ancient Chinese working people and it is one of the greatest projects in the history of human beings.

Wish you all the best. Hope to see you soon!

Yours,

Li Hua
