I'm one of the locals. I always think the cxcpp is not suitable for foreigners seriously. I dont know why so many outside HK ppl are so enthusiastic to apply for it. Property market here is saving bubbles to burst, if you know some economics. The living condition will change a hundred percent while some ppl can enjoy their big garden in the backyard in US or AU, yes, you can still have the same environment, but please pay over 10M at least for it.
There is one industry I would suggest for foreigners: finance.
What HK is selling is an international financial centre.
If you are not rejected by other airlines, please dont go for cx.
