Millions of migrants from China's interior come to the Pearl River Delta to work at factories in hopes of building better lives for themselves and their families. They often work and live in giant factory compounds producing goods such as shoes, electronics and toys for export, as well as for the growing domestic consumer market. Others toil at the smaller-scale "black" (illegal) factories that dot Shenzhen's working-class residential neighborhoods.
But manufacturing in China comes at a cost. In the black factories, there are virtually no safety standards. Even in legal factories, injuries to workers are common because management values productivity far more than worker safety. Workers have little knowledge of their rights.
