Sanitation worker Dong Jidong pushes his wife Dong Jinxiang on a wheelchair before working in Xinluo District of Longyan City, southeast China's Fujian Province, Jan. 9, 2019. Due to femoral head necrosis disease, Dong Jinxiang has been living on a wheelchair for about a decade. To take care of his handicapped wife, Dong Jidong, who himself has been afflicted with ankylosing spondylitis, gave up his work in a cement plant and chose to clean the streets near their home two years ago just in order to take better care of his wife. Everyday, Dong Jidong works in the streets with his wife's companionship. (Xinhua/Song Weiwei)
