Hi,
I have been in the same situation you are now. Tempted by the good salary and how good looks Sanya considering the rest of China. It seems that Sanya it is only a sweet to attract pilots to choose BCA and that most probably you will be based in PEK or CAN. But these, you will only discover once you are half set in China and your options will be to move to those bases or to resign to work in China for a long time.
Hope it helps and if it changes, just let us know.
Good luck,
nopoal
