What I know
This guys are saying that China is Cheap? it all depends of where and how you live!
Just look in google and you will find out.
Big city in China you ae looking at 10K CNY to live (2 bedroom, cable, internet hot water, heat and A/C in a decent apartment complex where people do not spit around you) Leaving expenses... food and drinks anywhere from as in any big city NYC-Paris-Moscow to 5 times cheaper.
Kids is where you going to suffer (read pay)
I would go with a company that you can take to court at home (in China the law is more of a joke than at home)
