      Shared bikes have been very popular since they were put into use. The shared bikes like 
Mobike bring great convenience to people. You needn't lock them by simply using your smart 
phone. They can take you where the subway and bus don't go. And they can be left anywhere 
in public for the next user. Besides, shared bikes are beneficial to our health, because using 
them can reduce air pollution. And the cost is not high and affordable.
      However, there are some problems. Some people can't return it in time. Some people 
park them everywhere. Others damage the QR code on the bike, or use their own lock, which 
causes trouble to other users. What's more, Some vehicles were badly damaged.
      In my opinion, it's difficult to turn these people's ideas in a short time. Therefore, 
bike-sharing companies like Mobike need to do something. For example, those who damage 
the bike should pay for their actions. Also, because people use their real name to register as 
a user, it's a good way to connect to one's personal credit. In the end, what I want to say is 
to take good care of public services.
