I made the move to China and then Hong Kong about 11 years ago and don't regret it either.
Anecdotally seeing increasing numbers of "high tech" people moving to Hong Kong / China too. 10 years ago it was mostly people looking to source cheap goods.
Fast forward 10 years and in Hong Kong, we finally have our first tech startup unicorn, Bitmex [1]
It will be good for everyone to spread the talent and innovation around.
