Origin . In 1955, farmers reported that sparrows were damaging crops. When
Mao Zedong, then
Chairman of the Chinese Communist Party, received these reports, he said sparrows were harmful pest birds and should be eliminated. In January 1956, after discussion by the
Politburo of the Chinese Communist Party and formal adoption by the
Supreme State Conference, the expanded version of the Draft Outline was adopted. Article 27 of the Draft Outline stipulated that starting from 1956, rats, sparrows, flies, and mosquitoes should be more or less eliminated in all possible locations within 5, 7, or 12 years, respectively. and the
Four Pests campaign was implemented across the country. Subsequently, "sparrow suppression headquarters" () were established in various parts of the country, with local leaders directing efforts, and the Eliminate Sparrows campaign was launched. Newspapers across the country reported on the campaign extensively, often using military headlines and "The Sparrow Extermination Army Has Achieved Brilliant Results". A folk song circulating at the time was called "Beat Drums and Gongs to Eliminate the Four Pests" (): {{Translated blockquote On April 21, 1958, the Beijing Evening News published a poem by famed writer

Ba Jin and other high-profile experts actively participated in the sparrow-hunting campaign. The ''
People's Daily'' reported at the time that more than 2,000 scientists and staff members of the
Chinese Academy of Sciences participated in the "battle". On January 8, 1956,
Tso-hsin Cheng, renowned Chinese ornithologist and researcher at the Institute of Zoology in the Chinese Academy of Sciences, published a lengthy article titled "The Harm of Sparrows and How to Eliminate Them" in the ''
People's Daily''. Later, he also compiled pamphlets such as "How to Prevent and Eliminate Sparrows" and "Preventing Sparrow Damage". Nevertheless,
Zhu Xi, director of the Institute of Experimental Biology of the
Chinese Academy of Sciences (who had almost been labeled a rightist in the 1957
Anti-Rightist Movement),
Feng Depei, a researcher at the Institute of Physiology of the Chinese Academy of Sciences, neurophysiologist
Zhang Xiangtong, and other scientists demanded that sparrows be "
rehabilitated." A firsthand account from a former
Sichuan schoolchild at the time of the campaign recounted, "It was fun to 'Wipe out the Four Pests'. The whole school went to kill sparrows. We made ladders to knock down their nests, and beat
gongs in the evenings, when they were coming home to
roost." To organize and promote the campaign, meetings were held and propaganda posters, leaflets, films and
jingles were created. Contributing to the campaign was seen as a citizen's patriotic duty. Tools employed included wire clamps, wire cages, bamboo poles,
red flags,
firecrackers, stones, slingshots,
gongs,
megaphones, washbasins,
air guns, and scarecrows. The campaign depleted the sparrow population, pushing it to near extinction within China. == Impact ==
