According to her online bio, she moved to the US when she was 8. That means her immediate family are probably in the US, but she'd have extended family in China.
Chinese society is extremely family-oriented. Xi Jinping has been much more aggressive with government power than his immediate predecessors, but his biggest themes are conservative and traditional. Lots of taoism and confucius.
I'd posit that their government doesn't go after (han chinese) families because it turns one dissident into 50.
