Alex8 -> Hong Kongian is a lingo mate, we English speakers all have our own lingo, slang and colloquial language. In Australia, many people from Hong Kong refer themselves as Honkies, I prefer Hong Kongian, and its widely understood. Well it seems like you have understood what I meant anyway, so my purpose of conveying my message across is complete. Language is a working piece of art, the more creative the better.
