In the middle of the night on February 15, the installation department received a special urgent task from the company to install two sets of aircrews for the Shanghai Public Health Clinical Center, the designated hospital for the treatment of patients with new coronary pneumonia. It is required to enter the construction site on the 17th, and the preliminary preparation time is only one day. It is necessary to ensure that the entry of United Imaging Magnets on the 18th is not affected. This is difficult to accomplish in normal times, and the task is even more difficult during the outbreak of the epidemic!
