Doctor Sun Qingyong (R) gives a patient intravenous injection at a clinic in Shaluo Village of Guanghuojie Township in Ningshan County, Ankang, northwest China's Shaanxi Province, Aug. 15, 2018. Sun became paraplegic in a traffic accident 22 years ago. He soon started offering medical treatment to his fellow villagers on a wheelchair. A large number of medical practitioners are active in China's rural areas where health care is still underdeveloped. Under adverse working conditions, they have carried forward the humanitarian spirit and devoted themselves to the health of rural citizens. China will mark its first Medical Workers' Day on Aug. 19, 2018. (Xinhua/Liu Xiao)
