Over the last hundred years China's capital city Beijing has developed at an unprecedented pace. The population has grown from just 1 million to now more than 20 million. The city wall and its majestic gates are long gone. This change, from a dusty imperial capital to the ever growing megacity of today is very hard to imagine. "Beijing on the Move" is a visual portrait of this transformation. It describes how every gate in the old city wall had its own purpose: a gate for water, coal, alcohol, for soldiers marching in to war, and one for excrements. It's the story of how the walls and gates were gradually torn down and opening up the city for the ever increasing traffic, and how twisting donkey drawn carts and long lazy camel caravans and wheelbarrows were overtaken by rickshaws and tramways, before they in turn were surpassed by automobiles, metro lines and bullet trains. Will the staggering pace of Beijing's development ever slow down? And how will Beijing continue to cope with half a million new immigrants every year, when the city is already struggling with severe water shortages?
