I am not sure it is so bad there. I lived in HK from 2013-2014 and the pollution was bearable. About 60-120 on the AQI scale (PM2.5)[1]. By US standards that's orange/red (bad) but you get used to it. In comparison, Beijing is routinely 500+. Manhattan is about 40. And some parts of the west coast push 100+, most likely because of Chinese air floating all the way over the Pacific. http://aqicn.org/city/hongkong/ http://aqicn.org/city/hongkong/
