I have some second hand anecdotal evidence from someone who used to live in Urumqi and now lives in Canada. She said not being Han Chinese is basically not a good thing to be in China. And having a passport / being a dual citizen is a good thing. She didn’t talk about anything egregious like what some of these articles describe but she did say that when it comes to politics, positions of power and government processes, Han Chinese are always getting preferential treatment.
