On my last way to Tokyo I decided to make a stop for some days in Hong Kong. A friend from London joined me and so we had some days and nights with no sleep there. The nightlife of HK is spicy.
At the daytime you can explore the island. I have spent my days at Victoria, but also went to Kowloon. And you can have a look at the typical HK attractions:
Pencil styled buildings, I guess 25% of the floor space is taken by elevantors and stairs
HK train, same concept as the buildings: thin and high
HK harbour on Kowloon side
Good old Star Ferry
