Each user of the Mobike service is evaluated by points. When registering on the app, everyone is initially given 100 points. One can earn more points by using the service and obeying the rules or reporting cases of rule breaking. Huzi now has 1,701 points of credit, most of them from the hunt and rescue operation. As of now, he has reported or rescued more than 1,000 bikes. [Photo/VCG]
