　　An unforgettable journey

　　I live in Shanghai with my parents. Last summer holiday, we took the high-speed rail to Beijing. The high-speed rail was very fast. It only took us more than five hours to get there. We got to Beijing at 1:00 in the afternoon. We lived in a hotel near the train station. The next day, we went to Tian'anmen Square. And then we visited the Forbidden City. On the third day, we did some shopping in Wangfujing Street. On the last day, we went to the Great Wall. We stayed in Beijing for four days. We had a good time there.
