Sharing bike can be seen in every corner of the street, which is very popular by the public. The foreigners speak highly of sharing bike, because they can ride the bikes to look around the city and the expense is very cheap. As people enjoy the convenience of these bikes, the problem comes. We can see that many bikes have been broken and some are even put in the main road, which brings trouble to the public. Of course when the media reported the phenomenon, everybody condemned the negative behavior. Sharing bikes are public property, all the people have the responsibility to protect them, so after using them, we should just find a right place to lock them. The small act can present a person’s nature, so don't let yourself be the rude one.
