With its towering skyscrapers and busy streets, many people think that Hong Kong is all that it appears to be. But look closely and you'll see that behind all this glitz and glamour, Hong Kong has a wealth of fascinating things to offer. As Asia's most vibrant centre for art and culture, Hong Kong has demonstrated its creative spirit in everything from world-class galleries and exhibitions to international art events, especially in street art. Over the past few years, street art has given Hong Kong's cityscape a bold and innovative look - the East meets West murals in Central, the graffiti art in Wong Chuk Hang Industrial Estate, the colourful and creative works in Sham Shui Po. The paper explains and demonstrates cultural and business aspects of Hong Kong Street Art based on its characteristics. Further recommendation of the continuing transformation of Hong Kong Street Art is proposed in the last section of this paper as well.
