Last week I went to the Summer Palace and met some American tourist by accident. I greeted them with English and then we begin to chat. I got to know that they were college students travel in China, most of them were fond of Chinese culture. They were busy taking pictures and were amazing at the changes that had taken place in the past few years. After that, we went boating or had a good time. We were exchanged our e-mail addresses so that we could write to each other in the future. I was gladly to have a chance to practice my oral English. What exciting experience it was!
