China's gigantic mega-cities reveal a striking divide between rich and poor

If all goes to plan, China will have moved 250 million people - equivalent to the entire population of Indonesia - into its burgeoning megacities by 2026.

The move lies at the heart of the "National New-type Urbanization Plan," a program launched in 2014 that expands existing cities by gobbling up rural farming communities on the fringes.

The goal is to make China better at making and selling its own goods instead of relying on shipping clothes and electronics overseas to make money.

But as photographs of the transition reveal, sometimes the real cost of building highways, bridges, and rail lines threatens people's entire way of life.
