The original set consisted of four volumes, with materials going up to the revolution of 1949 but not after. This set was printed several times during the Cultural Revolution. Because of the unstable political situation and changes in Party line, it was impossible for many years to decide which post-1949 texts should be upheld in a new volume. It was only after Mao's death, when Hua Guofeng (Kuo-feng) was trying to cement his legitimacy as heir, that the fifth volume finally appeared (not included here).
