It is brutally expensive to live in Hong Kong if you want to maintain your western standard of living, apartment, food, clothes.
If you want to live in Kowloon, shop at the local market for local food, ladies market for clothes that salary may work. Drink at the Circle K bar...eat DimSum at the corner "restaurant" or McDonalds.
If you want to live in DB/TC or Central that pay is not enough. I make HKE. salary in housing alone.
Naive, very Naive.
