Ok, so a friend and drinking buddy of mine in Wuhan used to work with one of them. He got into a bad business deal with a Chinese national, who basically scammed him out of the money. The police didn't do anything because he technically shouldn't have been conducting business on a teaching visa (or something along those lines). Deeply bitter about it he started criticizing the government and China as a whole, which got him in trouble, a slap on the wrist (no jail or fine, just cautioned), then he left China and started hating on China professionally. He's been seething ever since.

Kinda wild I'm 2 steps removed from that dude.
