I went to Beijing on vacation with my parents last month and we stayed there for a week.
To my surprise, Beijing is such a modern city that my parents and I all admire the development of it these years. We visited many wonderful places there, such as the Forbidden City, the Summer Palace and the Great Wall. What impressed me most was that people there were all very friendly and some of them could even speak Enlish. But still I think that there are some problems of this city, which I dislike. Those are too many people there and the heavy traffic. If there were fewer people and less traffic, it would be better.
