For me the good does outweigh the bad, I have been here nearly two years and have no thoughts about moving on yet.

The good,   cheap housing and living costs, frequent affordable public transport, better social life than back "home", friendly people, an unbelievable amount of beautiful women, climate (apart from the humidity sometimes), cinemas (just need more western films).

There is only one bad thing and that is poor education, this is reflected in poor service from the majority of businesses, the poor quality of work, the ignorance and rudeness of some people, a blinkered approach to problems and alternative ideas. If you educate people properly the majority of the problems including pollution, corruption etc will disappear.  I know there will always be exceptions but I really feel education is the answer to most of China's problems. You just have to wonder why the education system is the way it is.

Yea, I'm not here because my life in China is somehow better than it would be in my homeland. It isn't in any way. I came here because I was young and I wanted to have an adventure. When I leave it will be because that adventure is over and I want to raise my children in a better environment.

Good and bad are very subjective terms and that subjectivity is further differenced by personal tolerances and situations. 

For me, yes most definitely the positives outweigh the negatives, the biggest plus for me is the fact that my wife's family are here and offer us constant help and support, as do her (our) friends.

The other 'sort of' positive I  add to the mix is the potential, I find it quite invigorating to be in the midst of an emerging power, a nation and a people that I honestly think have an enormous chance to drastically change the global geo-politic. Whether that change is for the better or worse (and for whom) remains to be seen and is part of the reason I'm staying here.

You need at least a generation to see these changes taking place. Yet, the generation that comes out of the actual one is still contaminated by the way people live today, a sort of life where the bad, as defined by you prevails the good. The condition for the hoped change would be a very strong endeavor from the young Chinese people to follow other models of life that allow such good to be promoted and actually happen. The education it's the best tool, starting kindergarten up. Nonetheless it would be the 2nd generation that away from their grandfather's bad stile of life and in between them and their parents generation, they would set a steady basis of a civilized and healthy public and private life stile. 

If you sum up the amount of time needed to see this happening, well, then consider at least 60 years more. But all that only if the Chinese people are in need of such change. 

It's all subjective. Do you live in a nice place with mostly good people? Or can you handle all the BS that happens here every day without speaking out? If so, you'll be fine and the good will outweigh the bad.

If, on the other hand, you can't put up with injustice, you'll suffer here. If you can't keep your stupid mouth shut, you'll get into trouble almost every day... like me. Now you know why I'm always getting in trouble here. I don't suffer fools gladly.
