One possible version：
Dear David，
I'm happy to hear that you will visit the Great Wall. Now I want to tell you something about it.
The Great Wall is more than 8，000 kilometers long and five meters wide. In ancient China，it was quite difficult to build such a great wall. Without modern machines，the Chinese workers did all the work with their hands and wisdom.
The Great Wall is famous all over the world. It's the pride of the Chinese people. Do you know the old Chinese saying “He who does not reach the Great Wall is not a true man”？ I can't wait to see you.
Yours，
Sam
