A sanitary worker sweeps the floor in the Fengtu Charitable Granary in Dali County, northwest China's Shaanxi Province, June 17, 2015. Fengtu Charitary Granary, which is 17 kilometers away from Dali County, is still used to store grain even though it has more than 100 years of history. The intact granary, which was built in 1885, is a circular town in which 58 caves each is able to store 90 tons of grain. It was famous for the title "The No. 1 Granary" named by Empress Dowager Cixi (1835-1908). (Xinhua/Tao Ming)
