In the new historical period of the dictatorship of the proletariat, the proletariat enforces its dictatorship and exercises its leadership in every field of work through its vanguard the Communist Party. Departing from the dictatorship of the proletariat and from continuing the revolution under the dictatorship of the proletariat, it is impossible to solve correctly the question of Party building, the question of building what kind of Party and how to build it.

Liu Shao-chi's revisionist line on Party building betrayed the very essence of the Marxist-Leninist teaching on the dictatorship of the proletariat and of the Marxist-Leninist theory of Party building. At the crucial moment when China's socialist revolution was deepening and the class struggle was extraordinarily acute, Liu Shao-chi had his sinister book Self-Cultivation republished and it was precisely his aim to overthrow the dictatorship of the proletariat in our country and restore the dictatorship of the bourgeoisie.
