Photo taken on Nov. 28, 2012 shows new houses at Shuangming Village in Huating County, northwest China's Gansu Province. The coal-rich county once suffered from environment degradation due to exploitation of natural resources. Great efforts have been made in recent years to repair the environment, and now the county has turned to be a liveable place with clean air and beautiful gardens. (Xinhua/Zhang Meng)
