Obviously you have not been in conversations with Chinese. If there’s one thing they have, it’s an opinion of others. Since Chinese can get into trouble crticizing the government, they’ll verbally attack a person or people. Chinese are famous for stereotyping other Chinese, as well as foreigners.
In Hong Kong, I used to get a chuckle out of the Cantonese hotel maids who would curse the “hairy foreigh whores” standing right next to them in the elevator.
Quite frankly, a lot of the young Chinese have a real chip on their shoulder - part of the Global Whining that’s on the rise.
