I'm Li Hua. Welcome to Hangzhou. As is known to all, Hangzhou is not only famous for its breathtaking sceneries but also for its convenient bicycle traveling system. The usage of public bicycles is free of charge within 60 minutes. Besides, you will find it convenient to rent as well as return the bicycle, for the bicycle stops are placed in every corner of the city As for the advantages of using bicycles, for one thing, bicycles don't need any petrol and they are energy-saving. For another, bicycles are environmentally friendly because they won't give off waste gas. What's more, riding bicycles is a good way for us to exercise and it is beneficial to our health. I hope you can have a nice time traveling in Hangzhou and enjoy the scenes by bikes. 答案不唯一
