describe a change that will improve your local area

well,recently xi'an has lauched its own bicycle sharing system ,a service in which where bicycles are made available for shared use meant to be shared by individuals on a very short period term basis.Bike share schemes This service allow people to borrow a bike from point "A" and return it at point "B".
To use the this bicycle-sharing system,you need to apply for a specially-designed public bicycle e-tong card with your ID card, passport, social security card or other official ID document.After you have got the public bicycle e-tong card, you can simply tap by tapping the card on the top of the smart parking stake to rent a bicycle, and return it by putting the bicycle back at the parking stake at any of the stops and swipe your card again. In addition, bike-share systems offer subscriptions that make the first 30–45 minutes of use either free or for a very cheap rate inexpensive, encouraging people to use them as for transportation.
this system provide free or affordable access to bicycles for short-distance trips in an urban area as an alternative to motorised public transport or private vehicles, thereby therefore reducing traffic congestion, noise, and air pollution. Bicycle-sharing systems have also been cited as a way to solve the "last mile" problem and connect users to public transit networks.
in my opinion,If you’re looking for somewhere to escape from the stresses of daily life stress and don’t want to take the crowded buses or subways,bike-sharing is a the best choice for you and it is very covenient.convenient
