Good for you! I have heard great things about Hong Kong!
Despite being part of China now, HK still seems to have a contrarian bent and outlook. Protests against govt intrusion more likely there than in the mainland of course.
Having been there before turnover, a couple years after, and 15 years after I can say things are starting to change and the mainland is definitely taking a heavier hand in the last few years. Singapore is the place for freedom in that area now.
