Members of the "Xieyun" orchestra perform in a ward of Peking Union Medical College Hospital (PUMCH) in Beijing, capital of China, April 23, 2018. In 2015, PUMCH doctors and Peking Union Medical College students launched the "Xieyun" orchestra. Every month, members of "Xieyun" would voluntarily stage one or two musical performances for patients, their families, and other medical workers. The orchestra was widely appreciated by its audiences for its performances and the members' concern and love for the patients. (Xinhua/Zhang Yuwei)
