City on Steroids: Vanguard

China is building mega cities like this at a pace and scale the
world has never seen before. Chongqing has 12 million people and counting.
It's part of the central government's plan to bring some of China's economic
boom to its impoverished interior province where three out of four Chinese
live. Vanguard takes you on a whirlwind tour of the city---from inside a
cramped boarding house where migrant workers to inside a starter apartment
of China's new class of yuppies; from inside ancient, crumbling teahouses to
gleaming new car factories.
