Chen Liping cleans a commuter bus for frontline health workers during a battle against the novel coronavirus epidemic in Yinchuan, northwest China's Ningxia Hui Autonomous Region, Feb. 6, 2020. For 12 years, Chen Liping has been working as a bus driver for the public transport service of Yinchuan. With a nation-wide battle against the novel coronavirus epidemic ongoing, Chen is now on a special, temporary mission: driving a commuter bus for frontline health workers who work at the Yinchuan No. 1 People's Hospital. "When our health workers are making every effort for the public well-being, the best I can do is trying to be a helpful 'escort'," says the 49-year-old driver. (Xinhua/Feng Kaihua)
