That's important, because China hadn't rolled out the "social credit" system back then.
China has a new approach to control. It's not Orwellian. It's not the USSR's. It's not a police state. It's a new thing. It's the gamification of authoritarianism.
The previous system of control was run through the "work unit", when almost everybody worked for the state. The party mostly acted through work supervisors, rather than cops. That started to come apart once there were more private employers. The social credit system is an attempt to get back that level of control. It's going to be interesting to see how this works out.
it doesn't apply in 2018? ;) anyways, the rules here are "randomly" applied... it's a bit like a "communist" country... it has a bunch of rules but they are being applied selectively.
