Speech During the Great Clean-Up in Yan'an[1]

(March 21, 1937)

Pay attention to hygiene and keep the body healthy—this is to increase the strength of national defence. Carrying out the hygiene campaign is not a matter for one person alone; it must be done by everyone.

[1] From March 15 to 21, 1937, Yan'an held a Hygiene Campaign Week, with a great clean-up carried out on the 21st. Leaders including Mao Zedong and Zhu De took part in the great clean-up and delivered important speeches. This is part of Mao Zedong's speech.
