I'm not local but I have friends there. The Chinese were accepting of the pollution at first because of the success they were experiencing on a world stage. They figured that if the politicians and the higher ups could deal with it, then the ordinary citizen can too. Then the average citizen started realizing that the elite didn't actually have to deal with it because they would buy expensive air purifiers for their homes, cars, and work places. There has been more of an outcry against the pollution that is now causing all forms of health problems as of late and despite the heavily authoritarian rule of the regime, the Chinese government is prudent enough to know that a largely dissatisfied citizenry is always a risk. So the various local and national governments are moving, albeit slowly, to try and reduce their pollution levels.
