From friends there, the Sanya gig is probably one of the best deals going in China right now. One thing to watch out for is the bait and switch they offer of promising Sanya and then only delivering Beijing. The time delays and slow moving new joiner process is also something to watch out for. Another good A 320 option is Lucky Air in Kunming. Wish I was a bus driver as the pay there is way out stripping the current Boeing pay. Best of luck.
