Transition to HK (Hong Kong)

I am considering moving to Hong Kong but I am wondering a few questions. If any Americans would answers these question would be a great help...

What was the hardest part?

What was the easiest?

How was the food transition?

What advise would you give to people who plan on working there?

Would you do it again?

Did the language barrier affect you? If so, how bad was it?

Did it change your outlook on life, America, the other culture?
Was life more or less stressful over seas?

Did you ever have a confrontation with another co-worker or person overseas? Was it resolved?

Were your co-workers and neighbors friendly, easy to talk to or were they more reserved?

How was the relationship between the superiors and subordinates compared to the US?
