Anecdotal, but...I don't know a single person who is interested in either returning to China or starting a new life there, and my social circles are overwhelmingly Chinese of all types (born here or Vancouver, moved here in grade school and grew up here, moved here for grad school, moved here as H1-Bs from PRC/Taiwan/HK/SG). For the ones who did not grow up here, they're predominantly from Beijing and Shanghai, with rich parents and connections back home.

My girlfriend (Beijing-born, came over as a grad student and stayed) has told me several horror stories of her time spent working as a SWE in China and Singapore. Based on her experiences, it seems like women should be especially disinterested in returning.

For the record, I would be ok with living in China for some time, or even relocating there long-term if/when the mantle is passed. Though I wouldn't do it without someone who speaks Mandarin.
