There are some built-in biases favoring some of the minorities, but there is a reason for this: to avoid that those minorities protest and push back against the PRC/Han China which in the mind of many is still an occupying force. Contrary to Chinese propaganda/school teaching these areas were hisotircally never/rarely in the same realm as the han-dominated regions.

But stepping away from perceptions: being any kind of critic (say, someone warning of a new corona virus epidemic) or just being the wrong religion/ethnicity can mean your life will be hell in China. Look at the treatment of those giving first warnings from Wuhan - even the globally/publicly known critics have been disappeared; and there are many more that never reached this visibility and have the same happen to them.

More at scale: more than 1 Million Uyghurs are in what propaganda calls 'vocational training institutions', which translates to them being brought to and held against their will in reeducation camps. The stories coming out of there ate nightmarish. Assigned CPC representatives live in their homes to keep watch, and in cases where one or several parents in those camps the children were forcibly put into orphanages and the parents have no chance to find out where they are and even less chance to get them back.

Sorry but China is absolutely and 100% oppressing these people, just for existing and daring to be born in a specific ethnicity/religion.
