Welcome to Hangzhou. I am Li Yue, president of the Student Union in my school. Id like to briefly introduce the Hangzhou Public Bicycle Service to you. Our city insists to protect the environment, so we began to use the Public Bicycle Service to reduce the traffic stress in 2008. There were 65 thousand bicycles for people to use in daily life. In general, more than 8 million people have to use them every year. Some people think they are very useful and believe they will make our society more beautiful. Others think they are not convenient enough. As far as I can see, reading a bicycle is so interesting. We can take exercise with it. Meanwhile, Our environment get protected. Lets go into action!
