I've lived in China for over 8 years, so with that being said, I've heard and witnessed similar stories a hundred times over and quite honestly it could have just as easily happened to a white guy. The difference is, whites are not judged/punished as harshly as black people in China. Had the same scenario happened to a white guy, he would have been deported. Hell, I know a white guy who got into a drunk fist fight with a cop. He spent six months in detention and was deported. Meanwhile, breh in OP's story is languishing in Chinese prison for 14 months and there's no telling when he'll get out.... and they have proof he didn't do anything. Go to Guangzhou and ask one of the hundreds of thousands of African Immigrants what happens to them if they run afoul of the law.
The thing is, Chinese men know that the primary reason white people come to China is to benefit from white privilege. White men come to China for easy p*ssy and the fact that they can get easy work simply because they are white. Being white in China is the ultimate life cheat code. Chinese pay whites to show up to events, board meetings, pretend to teach, lip-sync performances, model, act, and on and on.... Chinese in China don't receive the benefits of this white privilege so sometimes white people can be targeted based on how they move. I would say Chinese women practice white supremacy far more than Chinese men. Chinese women don't respect their men, that's why they dream of the day when a white man saves her from her torturous existence of being Chinese in China. Its just that most Chinese men are too Beta to say/do anything about it.
