You have a hypothesis with no backing. Back up your hypothesis, or accept that the citizenry of China support it because it works really well and is getting better all the time. Obviously people would change a lot about China, the major difference is that they expect the government to bring about that change, rather than assuming it won't.

Further, no, the rioters in Beijing were firebombing PLA vehicles and lynching officers before the PLA was sent in. That's why hundreds died.
