| Last week, I visited Beijing. I always look forward to visit there.Therefore, I was so excitedly that I couldn’t fall asleep on the night before I started. I got up early and pack for the journey. In my pack, I put camera, some clothes, mobile phone and so on. It spent me 8 hours to go there by train. I visited some place of interest. They are very beautiful. I enjoyed myself. I felt tired and excited because I learned a lot of about the history of the city. As long as I arrived home, I phoned my boyfriend and told her about my journey. _______________________________________________________________________________ |
