Could be true… But at the same side racism by chinese against black people (even when they come to countries in africa) is insane too. There is a huge racism problem in China but nobody covers it and it is not even frowned upon. The whole govt covers it up and is fine with it and is in on it too. I have no clue why they hate eachother so much.

So yeah it is a two way street…
