In the three years from 2019 to 2022, there were times of confusion and sadness, but more importantly, we were moved by the strong and unyielding spirit of ordinary people. Chu Jiangkuo, director of the Respiratory Department of Renhe Hospital in Yilin City, nurse Jiang Yan and his wife, and many more people have selflessly dedicated themselves to fighting the epidemic and even sacrificed their precious lives... Let us pay tribute to them!
