I have a good friend. His name is Tom. He is from the US. He came to China last year. He came here by plane. He visited many places in China. First he visited Shanghai. And then he went to Beijing. There he visited the Great Wall. It's very old and famous. It's a beautiful place to visit. He was very happy and he took lots of photos there.
