HES1998 Do not listen too much what people are saying on here. I mean, yes, do read, but also do your homework and own research.
I loved my time in HK and with CX. I moved on a while ago now, but gosh, had I read what people were saying 12 years ago, I would have never joined, and made a big mistake. Granted, the flying is not the most exciting (I hope you do not mind losing a few nights sleep every month starring at a dark windscreen). Taxes are low. Full stop. Yes, it is high compared to... the sand box. wow, great comparison!
Some people really need a reality check and see what happens elsewhere. Education is expensive, but the company will help you out. You will be making a lot of money with CX, and if you are not the biggest spender in town and you have a tad of wisdom (which I would expect since you are in this field of work), you will be saving quite a bit too. HK is a vibrant city. True, it has changed, but what has not? Live your life, enjoy the ride.
