For the prevention and control of epidemics, the campus should be the first. With the gradual approach of the school start time, in order to strengthen the prevention and control of the epidemic situation and ensure the school's smooth start of the school, Nantong Guangyi Electromechanical Co., Ltd. self-raised disinfection materials and hired professional disinfection personnel to conduct free epidemic prevention and killing for Hai'an Technical Secondary School.

At 8 am on April 3, the disinfection staff led by Cui Hua, the head of Nantong Guangyi Electromechanical Co., Ltd., went to Haian Technical Secondary School to prepare the disinfection potion, wear protective equipment, carry the air to kill the machine, and shuttle through the school. Buildings, office buildings, training rooms, etc., do not fall into one place, do not leave a dead end, and carry out a comprehensive and detailed killing.

The epidemic prevention and control cannot wait, and the campus disinfection operation is an important measure to ensure the opening of the new semester. Only when the campus fights the epidemic first, can the teachers and students learn and work in a safe, healthy and hygienic environment. The epidemic prevention and killing work continued until 5 pm. This disinfection operation uses the company's new smoke machine, which has the characteristics of good diffusion and high adhesion, and can fully guarantee the killing effect.
