Old photo: In the 1950s and 1960s, a patriotic health campaign was launched throughout the country with the core of "eliminating the four pests" (the four pests refer to rats, flies, mosquitoes, and sparrows, and after 1960, bed bugs replaced sparrows). This national movement has been elevated to the height of the people's war in the field of health.
Speaking of the various scenes of "eliminating the four harms", the older generation who experienced the movement have unforgettable memories. In the early morning, people climbed onto the roof with long bamboo poles, air guns or firecrackers, shouted flags, brooms, and towels, beat gongs and drums and washbasins to chase the sparrows. Families use boiling water to fill rat holes, smoke mosquitoes with six or six powders, and collectively go to toilets, vegetable farms and other places to hunt down flies... This movement has left the memory of a generation.
