Young Chinese children attend a kinderga

Young Chinese children attend a kindergarten set up for migrant workers, which is marked for demolition, in Beijing on April 26, 2012. Under China's complex residency laws, most migrant workers remain registered in their native towns and villages and do not qualify for the all-important hukou, or household registration permit, in the city where they live, and without this document, their children do not qualify for places in public schools, making the unregistered fee-paying migrant schools their only option.
