Big Brother is watching you and he makes no secret of it.

If you sign a mobile contract in China, you have to show your passport, even with prepaid. This way 'someone' can better assign the scanned phones to their owners. If you drive a car, you will be photographed at least every 20 minutes, and with the mobile passport connection, 'someone' always knows where someone else is. The same goes for crossing the street. Large screens are also set up here to show culprits who cross the traffic light on red.

All of this certainly has a deterrent effect, you are not only punished but also publicly embarrassed!

As I said, it is not hidden and everyone is aware of it.
