On another note, mainland China (including Canton) actually uses simplified Chinese writing (which came out from the Deng Xiao Ping era) whereas Hong Kong specifically maintians the traditional writing. The difference is literally less strokes and simplification of the characters. The infographic here uses the traditional writing. Personally I feel the two writings are mostly close enough that people should be able to guess what the other means. And AFAIK, it's a 1-to-1 mapping anyway.
Simplified + Mandarin -> Mainland China
Traditional + Cantonese -> Hong Kong, Macau
Traditional + Mandarin -> TaiwanAlso, many of the "simplifications" are based on Mandarin pronunciations, and were quite incomprehensible to me as a Cantonese speaker when I set foot into mainland China for the first time years ago.
