The function of our cardboard traffic cop is different though because when you are travelling in a car, you can't really distinguish whether it's a real or cardboard traffic cop. But when it comes to a 派出所, anyone can tell whether it's a real thing or not la.
VPD cardboard cop = effective (drivers can't usually tell it apart from the real thing)
Fujian plaster cop = fail (people can obviously tell it's fake)
If you don't have a brain, and least learn to keep your trap shut la, dumba$$~
