Lots of people trying for the China Southern 777 direct-entry captain job these days, including more than a few Emirates 777 drivers. Either things are worse than reported at Emirates, or the CSA gig isn't as bad as some people think.
It is definitely true that if you are NOT reverse-roster based on another continent, you had better find a way to love Guangzhou, China, because that's where you'll be most of the time.
