Asian School systems are brutal in general. I worked in Japan previously, and suicide among students there is higher than it ever should be. It's a mix of bullying from students and bullying from teachers that pushes kids over. From my friends in Taiwan, their system is closer to Japan in that regard. It's an issue in mainland China, but a bit different. Chinese schools are overpopulated, and that's the core issue. Most classrooms have 60 students or so. Homework takes hours and is just quantity over quality. I feel bad for the little buggers - if you want to play games, you do it at 2 in the morning or so and catch up on sleep in your lessons. Expectations are high, but the grueling busy work is what students complain about here.
Healthcare is awesome here. Rarely, but not never, doctors just shuffle you along because they couldn't be arsed to do the work if you come in with something odd. Allergies being the usual culprit. Other than that, I can get a full physical, a consultation session and also some dental work every year and rack up less than 100 USD in costs.
There are a lot of people in China, and they don't mind being close to each other in the way others do. US places (except big cities like Chicago and NY) feel underpopulated to me. I also stand way too close to people when I'm in the US, since personal space is smaller here. Where I live, the population density isn't very high, but it can feel that way sometimes. Supermarkets right before holidays, train stations at rush hour, these places you really stand shoulder to shoulder at times. I've lived in Shenzhen before, and that was much worse. Either way, the small towns and villages are pretty empty and it's usually only a two hour drive or so to reach some sort of seclusion. Maybe Beijing and Guangzhou excluded - since they're sprawling megacities.
Overall, I really love it here. Life's easy, safe, and transit is exceptional. Easy to travel and try new things.
