From someone whos done it:
Its better to make less and stay home if you feel confident you will have employment into the future.
In hindsight I knew the contract I signed was full of "shifty" things when I signed, but I wrongly listened to the flowers the Chinese were blowing up our behinds just to get us there- as they will say anything just to accomplish their goal of getting you in the seat so they can make their profits.
Why why why can't they just write a decent normal balanced contract? Really gents -why?
Maybes and we will tries and Ifs written into contracts -are just baiting.
Try this... Since the contracts are so bad and full of vagaries, they would not stand in any western court. So, just tell them for your protection you want the LAW OF JURISDICTION your home country. After all, why wouldn't thy say ok to that if they mean all they say and plan to treat you fairly?
It's because they want to keep an option open to screw you! I know a few locals and they laugh at how eager we sign up when it's so obviously dubious.
