The reports I’ve heard and read would be contrary to your claims. When I was in Hong Kong, for example, I saw huge protests, so I wouldn’t call it fine. Inside and out of Hong Kong, I’ve never met an HKer that was pleased about the China government’s plans. I also have heard that “its own system” is not a correct characterisation of the situation.

Have you been to Hong Kong?

Its own system? The entire local government was replaced with rubber stamp flunkies, all democracy activists were arrested, and it's basically a terror regime. No one in their right mind would move there or start a business there. If the intent was to maintain a separate system for the purpose of attracting foreign capital, so much for that.
