I've known a handful of PRC citizens (as co-workers, mostly) and I found it surprising how varied their attitudes/opinions were.
I would suspect it's those considered politically reliable who are permitted to travel/work/study abroad, but those I've had conversations with spanned a range of views I found surprising. Went from very conservative nationalism (weirdly hard-to-distinguish from Trumpery and complete with anti-black racism and admiration for the US right) to still-believing leftist Maoism (bemoaned the fact they met more communists here than they did back home), and others in-between.
I'm probably very naive about it all, as I'm only talking a handful of people, but they were much less uniform in their views than I would have expected.
