Oh man, you must be thinking of a different Hong Kong than I am!
If you value your time and sanity at all, you'll stay far away from Hong Kong corps.
it was fine for me for years but in the recent few years it's become an absolute, unrelenting nightmare.
If you love getting incomprehensible documents in Chinese multiple times per month, along with cryptic explanations in broken English from your service provider, along with an endless procession of fees, fines, audits, and filings—some of which you have to fill out by hand and mail through snail mail—then by all means go to Hong Kong.
But if you want to spend your time actually growing your business and doing high value activities, stay the hell away from HK.
