China's disabled children are sold into slavery as beggars

Nature Has not been kind to Gao Zhou Zhou - though not as cruel as other human beings. Her back is bent and bowed; her legs fold uselessly beneath her. She gets around using a homemade skateboard. Her arms, legs and face are very, very dirty. She doesn't know her age - she looks perhaps 15 - and she cannot remember her real parents. But she knows the pain of life on the streets of Beijing. 'When I first came here they beat me so hard I nearly died. They beat me and they beat me,' she says.
