A) The population of Beijing 21.7 million
B) When I am in beijing, I take subway and bus very often in China. It cost 2 RMB per ride by bus and 3 RMB per ride by subway.
C) I love the scenery passed from the window on the train, I always like to look outside to see the buildings pass by quickly, which is very beautiful. I also enjoy the light and the reading time on a train.
D) I hate there is few private space in the bullet train.
E) I love the New York train system. In my imagination, a Utopian train system for all would be like there is no requirement for line-up and check ticket, everyone can use their fingerprint as identification. There is no need for check in for luggage and the process for the suitcase is automatically done by the machine. There is music on the train and a small cinema inside the train. There is a sport background for people so they can play badminton and Ping-Pong.
