What was that stuff about being racist but instead of "race" saying "culture" so it's socially acceptable ?
Bonus from OP:
Not much we can do about that. It's just Chinese culture that hacking is a normal thing...their internet cafes literally comes pre-installed with hacks for online games because if the customers kept winning then they kept paying and renting PCs.
(no they don't, a couple years ago some twitter dipshit saw a computer in an internet cafe with a map tool that was approved by the game developer and thought it was a cheat)
"Chinese" people don't view other "Chinese" people as part of their ingroup. Thus they may be freely cheated, ripped off, etc. Your ingroup is only your hometown's people, and you can tell right away who's who because you have your own private language.
There are just too many people in China. Not enough to go around. Take care of you and yours first.
That is how a lot of countries without massive immigration go, I'm pretty sure.
