A sudden encounter with the novel coronavirus pneumonia (COVID-19) pandemic has made 2020 a different start. The COVID-19 global pandemic has become one of the most serious infectious disease threats to human life and health in the past century. Since the outbreak of the epidemic in China in January 2020, 29 provinces and military systems across the country have fully carried forward the spirit of selfless dedication of "when one side is in trouble, all sides support", and quickly sent 345 medical teams and more than 42,600 medical staff to "retrograde" Hubei, the hardest hit area, and fought day and night at the forefront of the epidemic fight. We are forever grateful to every medical staff who "fought their lives" on the front line. After nearly three months of arduous battle, they built a life channel and safety barrier between the epidemic and the people, in exchange for the phased victory of epidemic prevention and control in China.
