In January 2022, the Jinnan District of Tianjin met with COVID-19, and the site of the park was controlled. The employees of the company quickly start the emergency plan, calmly, cooperate with the park to carry out nucleic acid screening, and be punctual and orderly; Reasonably arrange production internally, improve efficiency and reduce consumption; After exhausting the reserved industrial gas and knowing that new materials can not be sent to the sealed area, they can still actively turn to the enterprises in the park and get the strong support of the other party; In the face of difficulties, on the one hand, the employees do a good job in self-protection, guard the door and prevent external input. On the other hand, they take the factory as their home, are not dependent on each other, are positive and optimistic, and take the initiative in production. This spirit and executive power are really touching. With everyone's joint efforts, the production before the Spring Festival has not been interrupted all day, which praises us for having such good employees.
