Thirty years ago today, on February 22, 1995 (January 23, 1995, the Beijing City Intermediate Court ruled that Qiu Mandun lost the case in the Qiu's rat poison case in Wuji County, Hebei Province. Qiu Mandun was born in 1934 and was originally from Haozhuang Township, Wuji County, Hebei Province. Once known as the "Rat King", he is a controversial civilian deratization expert. He served as a soldier in 53 and was demobilized in 57, just in time for the Campaign to Eliminate the Four Pests. He developed the "Qiu's rat poison" and launched a large-scale anti-rat operation nationwide. On December 7, 1989, Nanning, Guangxi, organized a unified organization to kill rats, killing 350,000 rats, and the rat corpses weighed 82.6 tons; On December 20 of the same year, Qiu Mandun went to Bozhou, Anhui Province to guide deratization. He used 10 tons of medicine, and the deratization rate reached 91.4%. On November 1, 2005, Qiu Mandun killed more than 2 million rats in Qinghai Lake Farm. On June 17, 1992,"China Township Enterprise News" published an article by five experts, including Wang Chengxin, Zhao Guizhi, Deng Zhi, Ma Yong, and Liu Xueyan,"Scientific Propaganda of Rat Control", which was reproduced in 19 newspapers and periodicals across the country. Beijing, Tianjin, Nanjing, Shandong, Hunan and other provinces and cities have ordered a ban on the use of Qiu's rat poison. On August 12, 1992, Qiu Mandun filed a lawsuit against Wang Chengxin and other five experts in the Haidian District People's Court of Beijing City for infringement of reputation rights. On December 29, 1992, the Beijing Haidian District Court ruled in the first instance that Qiu Mantun won the case, causing an uproar in the scientific community and public opinion. On January 10, 1994, Wang Chengxin and other five experts appealed to the Beijing City Intermediate People's Court. Zhu Guangya and more than 200 CPPCC members called for the illegal production, sale and use of highly toxic rodenticides to be strictly prohibited. Lu Jiaxi and other 14 academicians called for: safeguarding scientific dignity and ensuring fairness in law enforcement, and suggested establishing a scientific and technological jury system. This triggered a discussion in the scientific and technological community on "safeguarding the dignity of science." On February 22, 1995, the Beijing Intermediate People's Court finally ruled that Qiu Mantun lost the case. In April of this year, the General Office of the State Council issued a special order and began to ban Qiu's rat poison. In November 2004, Qiu's Mouse Sticking Factory in Wuji County held an on-site exhibition in the provincial capital. Qiu Mandun, the vice chairman of the board, showed off his product-Qiu's mouse stick board. Within an hour, a total of 10 mice were killed on more than ten sticky rat boards spread on the ground. The test results made Qiu Mandian and his collaborators very satisfied. Qiu Mantun began a new journey.
