6 months contract
Everybody knows China pays the most money for your time. But always keep in mind that you will basically be on a 6 months contract throughout your career there. Every sim check is a possibility for one of the CAAC checkers to fail a foreigner. A lot of them are very nice and fair guys. But once in a while you will stumble on a guy who thinks, possibly correctly, that foreigners shouldn't be there and earn that much, and have better schedules. And that guy will fail you for no good reason. Yes, it happened to me, and it has happened to others after me, and it will continue to happen. It is extremely insecure.
