Ms Liu (R), a volunteer, and her teammate package food for medical workers in Wuhan, central China's Hubei Province, Feb. 26, 2020. Liu, a 24-year-old volunteer from Sichuan Province, drove dozens of hours to Wuhan on Feb. 3 with chefs and food materials to cook and deliver food for the medical workers fighting against the novel coronavirus disease (COVID-19) in the epidemic-hit city for free. Every day, about 400 to 600 sets of food can be delivered to hospitals by the team she is leading. Except providing food, she also collects and delivers other donated materials for hospitals. She won herself an affectionate nickname "Raincoat Sister" from the medical workers as she had to wear raincoat due to the lack of protective suits. She said she is determined to hold on till the end of the epidemic. (Xinhua/Cheng Min)
