Harbin police get help from drivers

At the beginning of May, Harbin's traffic management bureau launched a snapshot platform through its networking app, Bingcheng Exing, or Ice City E-Traffic, to encourage citizens to report traffic violations.

Users can upload their photos showing violations and will receive a cash reward of 10 to 20 yuan ($1.57 to $3.15) each time if the information is verified.

More than 15,000 netizens have registered.
