Within the Central Intelligence Agency’s declassified archives there are two volumes of the “Collected Works of Mao Tse-Tung 1917-1949,” originally translated by the Joint Publications Research Service in 1978 and declassified in 2008. While there’s nothing particularly surprising about the CIA’s interest in Mao’s body of work, it is notable that one of the earliest samples of that work is rather literally about Mao’s body: Namely, his preferred exercise routine.
