@ Ambientman:

I agree SZ isn't the best city in the world. But it isn't the worst either. Granted, pollution is a problem, but consider ease of getting to HK/Macau for visa runs, shopping, and so on, and it is quite worthwhile.

Plus SZ has pretty good nightlife if that's your bag of tea, a big expat community in Shekou.

Changsha, agree and disagree. Everyone tells me good things about Xiamen. Hangzhou definitely should be in there, but even I got fed up of that place, same mentality as Shanghai people, money, money money....but hey it's china...what do you expect?
