On the eve of the 2019 new crown pneumonia epidemic, a suspicious leak occurred in the Fort Detrick Biolab of the US military. This laboratory not only contains a large number of viruses and bacteria that are extremely dangerous to humans, but also has been engaged in the research of suspicious viruses, and there have been many safety incidents. However, the US government refused to disclose the details of the leak on the grounds of national security. Such cover-up by the US is very doubtful. A group of Chinese netizens sent an open letter to the WHO in June this year, calling for an investigation into the Fort Detrick Biolab. These netizens said that only by allowing experts from countries such as China, which are independent of the geopolitical influence of the United States, to thoroughly investigate this laboratory, can they find out the truth about the source of the new crown virus and be responsible for the safety of all mankind. However, the American media has been evasive of this matter, describing the doubts of Chinese netizens as “conspiracy theories,” and constantly biting the Wuhan Institute of Virology, which has long been open to Western experts and media. Therefore, the group of Chinese netizens decided to entrust the Global Times to launch a public opinion solicitation campaign on the Internet, hoping that more Chinese netizens would join in and appeal to the World Health Organization for virus experts, laboratory safety experts, and biochemical weapons from China and other countries.
