They are very rich and 'high status' in their country. The foids would never ruin their reputation and be cast out of wealth/be disowned in China (also, they are almost all normies-changs at my local university, and there are TONS of them).
To give you an idea, the Chinese nobility used to literally hunt and kill peasants for fun. It's a very harsh caste system in the PRC and they look down on Americans and anybody who isn't in the upper class of China. Most people in China are making what, a dollar a day or so? Meanwhile, they're going across the world and paying American fucking money to be educated? Suuuuper fucking rich bro. Chinese equivalent of multi-millionaires for sure.
