Yesterday I met a young student, that came from the USA, in the Palace Museum. It was first time that I had met a foreigner, so I went to greet her in English. He told me that he was a college student travel in China and he liked China very much. I volunteered to show him around to the museum. He was impressed by the Chinese buildings and busy taking photo all the time. He said he hadn't seen so beautiful buildings before. After that, we go boating on a lake but had good time together. I was very glad to have the chance to improve my speaking English.
