Taiwan is a far better place to live than China, IMHO.........and I've spent a lot of time in both places. In Taiwan the people are more civil (not ruined by the cultural revolution and communism). Food is infinitely better and safer in Taiwan. Healthcare is infinitely better and safer......and I've had kids born in both places so again I know what I'm talking about. Air quality is far better in Taiwan, although I haven't been to Kaoshiung in many years. That used to be crap but not near as bad as Beijing.
The Chinese airlines tend to pay better though. Last contract I knew about at CAL was A340 Captain at $9800/month. To give an idea, that versus the closer to $20,000/month at mainland carriers.
