Workers clean silt from the Nanming River in Guiyang, capital of Southwest China's Guizhou province, on Sunday. The provincial government plans to spend 4.28 billion yuan ($679 million) on a pollution-control project for the city's main river. In the first five days after the project began on Nov 9, 10,000 cubic meters of silt were removed from the riverbed. Photo by Zhang Tianlin / for China Daily
