Realizing a Great Revolutionary Unity According to the System [1]
(1967)

All factories, schools, departments, and enterprises must, under revolutionary principles,
realize a great revolutionary unity according to the system, industry, and class. This will
facilitate the establishment of the revolutionary "three-in-one" system, facilitate the
implementation of the "mass criticism" and "struggle-criticism-transformation" campaigns in
all units, and facilitate the promotion of revolution, production, work, and war preparations.

the Central Committee of the Communist Party of China, the State Council, the Central
Military Commission, and the Central Cultural Revolution Group regarding the
implementation of the Great Revolutionary Alliance based on the system. The notice also
stated: "All revolutionary mass organizations should base themselves on Mao Zedong
Thought and, after full consultation, follow Chairman Mao's instructions, based on their
specific circumstances. All cross-sector organizations should, on a voluntary basis, make
necessary adjustments based on their respective sectors." This quote from Mao Zedong was
first publicly published in the People's Daily editorial, "Follow Chairman Mao's Instructions
and Implement the Great Revolutionary Alliance Based on the System," published on
October 19, 1967.
