China is known as the kingdom of bicycles. Some cities have established their own bicycle sharing system to provide individuals with an alternative form of public transportation. Now bike sharing is a very popular means of transportation in China.
People around me are really proud of this green transport option. There are many advantages to using bicycle sharing. For one thing, using bicycle sharing can greatly contribute to reducing the air pollution and easing traffic jams. For another, bicycle sharing can provide people with chances to do exercises. Last but not least, it supplies great convenience for the local people as well as the tourists who want to explore the city.
Please cherish the bike when you ride the bike and it is not moral to do harm to the bike. After you get to your destination, don’t throw them away somewhere, although you have already paid for them. You should put them in a proper place.
