How China's Mass Surveillance Works
Imagine a world where everything you do, from meeting your friends to using a public toilet is recorded. Based on your actions ranging from what you buy to where you go, you are given a score similar to the way you rate an Uber drive. If the government believes what you are doing is socially beneficial, the score will increase and if not, the score will decrease.
If you critique, play games, your score decreases and when your score is low, you won't be allowed to travel, your children would be barred from applying to high school, you would be fired from your job.
