Do not be tempted by China. Many pilots look at the high pay and want it just as hungry dogs want meat baiting a bear trap. It is a very backward place to work and live. Not just Spring Airlines, but the whole thing.
Sure, you get beaucoup yuan and new planes. You also get a wildly reactionary and tempermental aviation authority that thinks nothing of destroying your career. You get a political / economic / social system that will amaze in its capacity to ruin.
