It's hard to not be bitter, if you live in China for years as adult person and not some student enjoying parties and iresponsible youth years. The amount of ridiculous stuff you have to deal with every day (incompetent Chinese management in companies, unproductive Chinese coworkers, people blocking sidewalks and in general extremely selfish people anywhere you look, overcrowded subway, fighting to get to suburban bus and constant flow of people cutting the queue, toxic air, toxic food, dangerous roads, visa harassment, etc. etc.) is just unbearable after some time and eventually everyone will move away. It's not exactly country welcoming foreigners, which would explain why they have like 0.5% of population consisting of foreigners, now tell me other country with comparable population of foreigners.

But yeah, most of HN readers saw China only online and see how is it booming and stuff like that. Like look at amazing Beijing subway with many new modern nice and dandy lines, somehow everyone fail to see they are still at 50% level compared to any western city (in west you have roughly one line per 500K served population, in amazing Beijing 1mil sharing one line with no suburban trains or trams to supplement it). Same goes for their amazing HSR - omit the fact they stole German and Japanese technology, omit the fact their prices are more expensive than faster and more convenient flying in Europe and that they closed most of cheaper slower lines, so end result for people is to pay significantly more to get home.
