On Yan Limeng's Pseudoscience

Within a few weeks of the spread of the new coronavirus from China to other parts of the world, a voice circulated on the Internet: Some people think that the new coronavirus is a biological and chemical weapon made in a laboratory.
Maybe someone else has made similar remarks. The credibility and proof measures are not high, but if this voice is made by a person with a scientific research background and a doctorate degree from a medical university, with the current Internet speed and heat, it will be important to China. In terms of it, it is undoubtedly an untimely bomb, and public opinion can push China to the forefront. This person is Yan Limeng, a postdoctoral fellow at the University of Hong Kong.
