Hong Kong was born thanks to the commercial exchange and this is still a very important business in the area (according to the Wikipedia, it is the eleventh largest trading entity in the world). You can easily notice it due to the huge number of cargo ferries in the area.
As the area in the city is scarce, and the coast line has also limitations, they have found a new way to increase the capacity of the cargo port: cargo platforms. This is another example of “If the mountain will not come to Mahomet, Mahomet must go to the mountain“…
Pretty interesting, isn’t it?
