Why do you study what you study?

I was sitting in the London Tube (train system in London) the other day and saw a black African with a guitar case beside his feet and a CD in his hand. Then I thought about this scene and compared it to the Hong Kong MTR (Mass Transit Railways system in Hong Kong).
How often do we see an adult of race other than the majority Chinese sitting in the mass transit railway system that fits similar profile?

With all the opportunity a city has to offer, why is Hong Kong not a magnet for people of all artistic abilities to come together in a city that has so much freedom in expression?
Are there other ways of expressing one's opinion on society and government beside demonstrations and slogan chanting that disharmonies the society?
Too much creativity is used in the process of criticising the government rather than creating an enduring artwork that is timeless.

You might say Hong Kong adopts the "Quick Eat" culture [熟食文化] (easy come, easy go culture since Hong Kong was a stop over for many in the turn of the last century). Then what do you make of century old brands [老字號].
What is so special about Hang Heung [恆香], Lok Yu [陸羽], Below the Lion Rock Mountain [獅子山下], Beyond music, Gangster movie [古惑仔電影], Martial Arts movie [功夫電影], why have they become timeless? And why was I using Pinyin, a Chinese mainland invention to type Chinese to input Chinese rather than an input system that is developed by Canton speakers that promote the Canton dialect.

Why is Hong Kong not a hub of artistic expression, of cultural expresion. A place where artists deprived of the freedom they would otherwise not have in media suppressed China, in tongue-tied embarrassing Taiwan (or Chinese Taipei in Olympics), in gender biased Japan, obedient Singapore, corrpution filled Phillipines, Thailand and many south asian countries.

The world looks to China for its opening market, the finanical centre will move to Shanghai as China's legal system becomes more transparent and reliable.
Tourists will want thousand year old treasures from Xi'an (if our government continues tearing down colonial buildings which make us so different form other Chinese cities).
New buildings are sprining up in Beijing at alarming rates, making it a cultural hub.

It's time for Hong Kong to treasure its freedom, democracy and historical heritage so that it can proudly adopt the title of Ny-Lon-Kong and be a true international city on the world map.

I hope next time, music being transmitted to my ears from train stations will be real singers performing in MTR rather than some random compliation of notes being played on the piano through speakers.

We have great potentials, because we are all made in Hong Kong.

That is why I study art history and architectural history.
