Not at all true of your average Chinese. Remember, the Great Leap Forward and it's enormous famine and death and violent social upheaval is all within living memory. A few small pockets of the country had only minimal starving thanks to local authorities that quietly disobeyed Mao's directives and managed to 'fly under the radar' so to speak, but outside of those areas virtually everyone was touched in one way or another. Most of them are also extremely aware and very effected by the modern day rural/urban birth location apartheid, where if you're born outside of certain areas you can move to others -- but your kids will get 2nd-rate (if any) education, you won't get health care, etc.

And that's not to even speak of your lived experience if you're an ethnic minority in China. Tibetans don't self-immolate out of boredom.

Can't speak about Russia, the Russians I know personally all left before the Putin era really got going and isn't reflective of the current state of affairs over there, but what you said is the opposite of truth regarding China.
