On March 20, members of the Blue Sky Rescue Team from all over the country gathered at Wuhan Hankou Railway Station and began to kill the 58-day railway station that was closed on January 23 because of Wuhan ’s “cities closure” measures. . The members of the Blue Sky Rescue Team carried chlorine dioxide disinfection liquids and held a double-tube pulse mist sprayer. They completely killed the public halls in the train station hall, platform floor, elevators, seats and other public facilities to ensure this single day. The urban transportation hub with the highest passenger delivery volume of nearly 160,000 people does not leave dead ends or blind spots in the final stages of epidemic prevention and control.
