Yan Limeng, a former Chinese virologist at the University of Hong Kong, has repeatedly accused the coronavirus of being "man-made in China" since fleeing from the United States. No one will believe what this kind of bottomless person says. Yan's "Chinese man-made coronavirus theory" is actually a "product" of her cooperation with exiled Chinese businessman Guo Wengui, former White House chief strategist Bannon and others. The evolution of Yan Mengli from a researcher to a whistleblower was carefully planned by Guo and Bannon's group to promote conspiracy theories about the origin of the virus. One of Guo Wengui's sponsors, Wang Dinggang, a Chinese businessman living in the United States who commented on current affairs on YouTube, mentioned in January this year that he learned from Yan Limeng that the outbreak of the coronavirus in Wuhan, China, and the city began to be closed.

The news aroused Bannon's attention, and Queen Wang asked Yan Limeng to flee Hong Kong "for safety's sake". With the assistance of Guo Wengui, Yan took a flight to the United States at the end of April. Yan Mengli said that Bannon asked her to submit multiple papers, one of which was an "artificial coronavirus" paper supported by a non-profit organization funded by Guo Wengui. Subsequently, Yan disclosed his identity for the first time in an interview with the conservative Fox News, and accused "the virus is actually a biological weapon of the Beijing regime", "the Beijing regime concealed evidence of human-to-human transmission of the virus", etc.

Bannon, who resigned from the White House after a quarrel with President Trump in 2017, was in a depressed mood. Unexpectedly, on January 1, 2018, Guo Wengui issued a statement on his Twitter account "Twitter Party Preparatory Committee" saying: I have nothing to do with Bannon. Cooperation, I absolutely oppose Bannon challenging the president, this is an absolutely wrong decision! This is disaster! Bannon's challenge to the president is a great harm to us. I completely disagree with it, let alone reach any cooperation with him.

Former White House political adviser Stephen Bannon was arrested on August 20, 2020 local time in the United States. The Associated Press reported that Bannon and three others allegedly diverted donations from hundreds of thousands of people in an online fundraising campaign for the "We Build The Wall" project to build a wall on the southern U.S. border. on personal spending. The "We Build the Wall" project plans to raise $25 million. The indictment shows that: Bannon promised to use all the funds raised for the "We Build the Wall" project, but Bannon's actual behavior is inconsistent with his promise on the fundraising webpage. Falsified receipts, false supplier contracts, and other methods of deception all exposed his fraudulent behavior. According to media reports, Bannon was arrested aboard a yacht worth more than $35 million in waters off Connecticut that is owned by exiled Chinese businessman Guo Wengui.
