I have a very good friend who just moved back to Hong Kong after being here for 47 years! He is enjoying it...the only caution I would put out is that Hong Kong is fully owned and ruled over by the Chinese government...and while they have been moving towards free markets there is no gaurantee whatsover that they will continue that. And, on a lifestyle aspect...after living for so long under totally secular government and society trust and honesty in ethical sense are rare...
I personally am considering Ireland or Canada.
Actually Honk Kong has been moving away from freedom if anything. Since the ChiComs have take it over, it’s not quite like it used to be under the British. It’s been pretty slow since the PRC does seem to realize that they can’t screw with the golden egg layer, but nonetheless they keep appointing toadies to the top position there, and things are eroded very gradually.
I look at overseas options and to be honest I don’t see much. This is primarily because I like my guns. Your options if you want to live elsewhere and still keep your guns:
Switzerland
...
Don’t really know of anywhere else, and becoming a Swiss citizen is extremely arduous. Even then with EU membership I don’t know how long the gun freedoms will last even there.
