Photo taken on June 11, 2014, shows the ancient residential buildings in Yongtai village in Baiyin city, Northwest China's Gansu province. Yongtai village was once covered by fertile land and surrounded by dense forest, but the place is now desolate due to lack of water and ecological deterioration. It was listed in the first batch of villages collected in China's traditional villages catalog in 2012. [Photo by Cao Zhizheng/Asianewsphoto]
