    I took our foreign teacher Mr. Brown, he came to China for the first time, to the Great Wall in last weekend. Having told about the history of the Great Wall, he was amazing at this world wonder. He was struck by the beautiful of the Great Wall. So I took photo of him, which would be a good memory for him. At the top, Mr. Brown was very interested in the activity of protecting the environment that he was eager to join in and then sign his name. Both the Great Wall or the Chinese people deep impressed him. He decided to visit more places of interest when free.
