Hong Kong first choice, Singapore 2nd choice.
HK business wise is pro business more laissez faire. Super easy to open a business, OPEN PORT no import/export tax, no five zillion regulations for doing business. They encourage businesses to setup and want them to thrive, very friendly to small business (how the USA was many years ago). Police are not ROIDED up, they are regular folks. There are no dog shootings, pepper spraying people if they don't listen, tackling old ladies or anyone they feel like. Everyone pretty much let's everyone be their own and do their own thing. Crime rates are super low.
Sure HK is part of China, but HK has it's own rules and isn't in the communist domain, u need a Visa to get into China, there's immigration and everything, it's going into a separate country.
At least you know when you're in HK you're not under some FALSE pretense that you are in the land of the free and protected by the constitution. I feel safer and more free in HK vs in USA.
Only bad thing about HK is the pollution, but that's negative side of a government taking a backseat to everything.
There's some corruption at the top, but it's pretty high up there, regular folks are not adversely affected much.
Besides that there is so much nature. Amazing parks, mountains, tons of hiking, beaches, gorgeous islands to explore. You can be in a beautiful hiking trail surrounded by nothing but quiet greenery and trees overlooking a bright blue reservoir with fish and turtles, and 15 minutes later you can be in the heart of the city that's more alive then New York Times Square. Every cuisine is available, whether, Asian, American, or any kind of European. They have the European PUB crawls, sports bars, and tons of basketball courts and other recreational facilities.
You get the comforts and pleasures of both the east and the west. Very few places have that perfect blend of east and west.
HK and Singapore are some of the safest cities in the WORLD.
Singapore PORT is also free, also a place where they WANT people to come so they provide incentives with low taxes and such. Clean, pristine, beautiful, big metropolitan, but still a quaint homley feel to it. It's the melting pot of Asia, pretty much every asian group is represented in Singapore, and they all just get along. Very family friendly, English is everywhere, with all the mixed cultures, everyone speaks english. Politically it's a bit different, because there's a ruling party/family, they control everything, even the opposition, and they have their hand in everything. There are some privacy concerns, especially the first couple years when they don't know you, but they hand out residency pretty easily. I know people who live there and love it, it's a slower pace than HK and they like it that way.
From my experience, you are left alone to do your own thing, and they encourage entrepreneurs to setup shop. Maybe when I'm older I will have different priorities, but for now I'd rather be in a place that actually likes to have me and allows me to work my hardest during my prime working years and not get bogged down by regulations and insistence by a President that my success is not my own.
