Anyone who’s been to China recently (including myself) knows the answer.The people of Mainland China live like savages...living in filth that would make any Westerner faint in shock.
I worked in a remote part of the Yunnan Province, China from fall 1976 to spring 1977. They removed a village to build a new fertilizer plant and moved the peasants into a new Soviet-style gray concrete block building about four stories high. At the end of each floor of the building were open window openings (no glass) in the stairwells. The residents would walk down to these openings and toss out their garbage. The place hadn’t been open much more than a year when I got there, but the mountain of garbage was about 20 feet high and the feral pigs were always rooting in it.
Now THAT was an eye-opener!
