assuming you are looking at figures as per Longreach Aviation for Beijing Capital A330;
Resident max is US$ 24.6K per month;
Commuter month on/month off US$ 15.5K per month
so don't know where your figures are coming from.
Regardless: YES there is a pot of gold out there for the vast minority who can get through the screening and adapt, as required, to the operating environment and hope to hell nothing real or imagined pops up on your medical every 6 months.
Good luck to any who can make it work for them
however please don't sell it as a "one page resume and bingo 2 months later you're earning the big $$$$" type scenario.
That's for the agencies to do!
Cheers.
