Roy, totally agree. Best would be a place to live that you really like and enjoy. If the move to HK is worth it is up to the individual. I find my personal alternatives (low cost, contract or corporate) overall less attractive, even if they would allow me a residence somewhere else. In the end it is all about the options you have, isn't it? If my choice was the right one I will tell you after my last day at work
United, I do not want to retire to HK. But why would that be relevant? I totally agree, HK is a temporary place to live ( as all are:-), at least for me.
