On May 20th, a video of a retired professor from Shanghai explaining disinfection knowledge to residents circulated on WeChat. The resident is a retired professor from East China University of Science and Technology, popularizing scientific knowledge about disinfection and fighting against ignorance. Based on his known scientific arguments, the elderly man raised many doubts about the high-frequency, high-dose outdoor fogging disinfection, believing its effect to be "negligible," while it causes serious environmental pollution problems. He also advised grassroots enforcement personnel not to blindly follow orders but to have their own thinking and judgment.
