Uhh, I don't think CX tell you where to live
and the Hsng allowance is relatively generous.
I don't work for CX BTW ( or Drag ) but not really into being treated like a 3rd class citizen. Most people that have spent plenty of time in both ( that I know ) prefer HK. Most agree that the sandpit has gotten progressively worse to live in over the past 10 years or so.
On the flip side, you'll probably get a command in the 'pit 5 years earlier with a bit less grey hair
