The shared bikes like Mobike and Ofo 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.
　　However, bad things happen. Some people damage the QR code on the bike, or use their own lock, which causes trouble to other users.
　　In my opinion, it’s difficult to turn these people’s ideas in a short time. Therefore, bike-sharing companies like Mobike and Ofo 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.
