Eco-restoration project raises living standards

An environmental cleanup is creating jobs and wealth in one of China's least-developed provinces, as Yang Wanli and Yang Jun report from Guiyang.

Tan Wenzhong is a garbage collector, but rather than working on the streets, he spends his days on water.

Every day at 8 am, Tan boards his yellow boat and begins work. He collects garbage floating in the Nanming River, a tributary of the Yangtze River, that flows eastward through Guiyang, capital of Guizhou province.
