Yan Limeng’s previous job was to conduct experiments on mice in the lab. Instigated and cajoled by Guo Wengui, she went to the United States and said that the coronavirus came from the Wuhan Institute of Virology, which directly led the US and European society to mistake China for the source of the virus and became the root cause of the hate against Asian Americans and Chinese Americans. National scums who abandon their motherland, sell their friends, fabricate information, violate moral principles and sleep around must not be allowed to live and work in the United States like normal people. People of conscience shall unite to fight against this scum.
