Folks who've immigrated for other reasons might have a different experience...
Your link shows: The CSC funds approximately 65,000 Chinese students studying abroad in a given year, and the same number of international students in China.[1]
Don't get confused with the CSC who mainly give scholarships (tuition, accommodation, stipend) to non Chinese nationals to study in China.
Escaped? Lolololol.
If China is as bad as the western mainstream media or some of those anti-China YouTube channels make it out to be, then all of those Chinese students (middle class or above) that studied in western countries would do whatever they could to stay but the majority go back to China to live and work.
Of all the Chinese friends I made in China, some are not satisfied with the CCP, mainly to do with the issue of free speech/censorship and that you cannot criticise the CCP openly. I would say the majority love their country, including the ones that studied in western countries.
