[Commentary] On June 19, at the Wanyuan Jiqing agricultural and sideline products market in Daxing District, Beijing, Yang Zonglin and his killing "comrades" started a new "fight."

  The highest temperature in Beijing reached 34°C that day, and the Beijing Meteorological Observatory issued a high temperature warning signal in the afternoon. Under such weather conditions, the killing team led by Yang Zonglin put on a full set of protective clothing, put on goggles, and wrapped himself tightly according to the specifications.

  Today, one of our teachers was very distressed when he took off his clothes. What is the concept? It is because the water you brought into the water tank was not as much as the water he carried. He suddenly suffered from heatstroke, and he vomited in protective clothing, but neither did he remove the mask or goggles.

  [Explanation] In order to cope with the killing operation under high temperature, the team also made special arrangements.

  Everyone in this team is equipped with water and Huoxiangzhengqi water. Try to (schedule) the working time to be staggered with the (high) temperature. I also hope that it can be understood by customers.

  [Explanation] Yang Zonglin said that the epidemic is no small matter. On the same day, they sprayed or wiped disinfection with chlorine-containing disinfectants in key areas selling aquatic products, meat, fruits and vegetables. In accordance with the requirements of other surrounding areas, a thorough and complete killing operation was carried out.

  One is called space retention spraying, which acts as a retention effect. It drops like a drop of water and instantly falls to the ground. After our equipment is finished, it will be suspended in the air for about thirty minutes. Will play a disinfecting role. But this liquid medicine just floats in the air, covering only the surface of our objects, and does not provide a deep cleaning. So the second method is to wipe it, wipe it with a higher concentration of chlorine-containing chemical solution.

  【Explanation】Unlike other killing operations on other occasions, you should be more cautious about the killing of farmers and fruit and vegetable markets. Professional and effective.

  There are many imported things in the fruit and vegetable market, so we actively communicate with customers, for example, his utensils, aquatic products and food must be removed or covered. If it is not removed or covered, we have no place to see after the killing, so let the customer do the cleaning the next day before using it again.

  [Commentary] Talking about the hard work of killing the team under high temperature, Yang Zonglin said that at the time of the epidemic, they just did what they should do. Now, their greatest wish is to hope that the epidemic will pass as soon as possible.
