Killing the four pests refers to flies, mosquitoes, rats, and cockroaches. On February 12, 1958, the CPC Central Committee and the State Council issued the Instructions on Eliminating the Four Harms and Stressing Hygiene. It is proposed to complete the task of eliminating flies, mosquitoes, rats and cockroaches in 10 years or less. Gradually, sparrows were "rehabilitated" and replaced by bed bugs. Later, due to changes in social life, bed bugs were replaced by cockroaches. Therefore, the "four pests" were eventually identified as flies, mosquitoes, rats, and cockroaches. In 1952, in the Korean War, the United States used bacteriological weapons in Korea and northeast China and north China, and spread a large number of pests and pests such as rats, flies, and mosquitoes carrying germs and viruses in an attempt to poison the Chinese and North Korean people. In order to respond to the great call of the bacteriological war against US imperialism, to improve the level of health, and to crush the enemy's bacteriological war, the whole country set off a patriotic health campaign centered on eliminating pests and diseases, breaking the old and establishing the new, eliminating the "four evils," tempering the people, and crushing the enemy's bacterial war. At present, 252 pathogens such as germs, viruses, spirochetes, and Rickettsia have been found around the world, and 114 kinds of four pests can be carried, so it is an important link in controlling the four pests.
