I don't miss Hong Kong too much. All my immediate families are living in Canada. And I have lost contact with most of my friends there. And after living in Western North America and getting used to all the space here, it's really difficult to live in Hong Kong again.
When we visited Hong Kong 10 years ago with our son, after 2 days he went crazy from confining to a hotel room with about 100 sq.ft (including the bathroom), a little bit larger than his bedroom. At first, we asked the hotel for a baby crib but then we could not move around the room at all. So all we of use slept in a double bed.
