Fu Jianghua (L), the head of Yangjia Hospital, checks a patient in the hospital in Wuyi County, Zhejiang Province, China October 19, 2015. Fu Jianghua has worked at Yangjia Hospital since 1983, when it was operated by a local mine, he is now the hospital's head. At Yangjia Hospital in a remote corner of China's eastern Zhejiang province, sufferers of dust lung spend much of their time hooked up to oxygen to treat lungs ravaged by work in a local mine, since shut down. Once equipped with high-tech machinery and 150 staff, the hospital has suffered from falling numbers and a lack of funding. With some of its windows broken and certain rooms abandoned, the hospital now treats just 30 patients. It's a close-knit community including family members, who prepare meals in makeshift kitchens, grow vegetables in the grounds and play cards to kill time. Dust lung, also known as pneumoconiosis, affects an estimated 6 million workers in China.
