I am in Wanghua District, Fushun, Liaoning. 365 days a year, at least 200 days, the sky is gray, and everything is covered with beasts like the Special Steel Aluminum Factory, the Third Petroleum Factory, the Xinfu Steel Carbon Factory, etc. Pollution from factories. However, no matter how polluted Wanghua District is, it is on par with the whole city and there is no smog.
