well, from what I heard in H, there are so many miserable stories, they had a huge layoffs last year and many couldn't afford the expensive apartment and jumped, some were locked and didn't have food and died of hunger. some worked in Chengdu worked and lived in Pixian where has heavy pollution after PX project and many got cancer.
whenever I thought of their miserable situations and I understand how important freedom is, at least we can complain freely here, in some places, no matter how miserable, they don't even have the chance to complain.
