Oxygenmask,
You should listen to the genuine advise proffered by all these gentlemen. HKA/HKE loves making empty promise. This place run by ' goons and thugs' (Hainan Airlines management). They possess not a trace of ability/intellect/business acumen/ethics!
Stay put where you are or you will regret immensely. Unless you could ask for unpaid leave from your existing employer and experience the torture for half a year
All the best
