article: During the last winter holiday, I went to China with my parents. The five-day trip left me with a deep impression.
  As the capital of China, Beijing is a very beautiful city with fresh air and clean streets which make the travelers feel very pleased. To my surprise, many people there were learning English. Later I was told that they did so because Beijing would hold the 29th Olympic Games and they wanted most foreigners to understand them. They strictly kept the traffic rules. When there was a red light, no one was seen crossing the street.
  Of all the places I visited, I liked the Summer Palace best. To our surprise, although it was winter when we were there, we still saw green trees and many fresh flowers. The whole park was very beautiful. We visited a very modern football field. We were told the buildings where the Olympic Games would be held were even better than that. I also enjoyed skiing in Xiangshan. Skiing is an interesting and exciting sport liked by many people.
  In my eyes, China is a nice place and Chinese people are very kind. In Beijing Station, there were so many people, and most of them were going home to spend the Spring Festival--the most important Chinese festival, with their families. Passengers helped each other carry luggage , and they were very kind to foreigners. We were given a card by the hotel we stayed at, on which was the address of the hotel. With the card we never got lost in the city.
  The five days passed quickly, but the trip left me a lot of sweet memories.
