When was it put forward that one is not afraid of suffering and the other is not afraid of death?

1In April, 969, the great man said in his speech at the First Plenary Session of the Ninth Central Committee: "I agree with this slogan, which is called' One is not afraid of suffering, and the other is not afraid of death'". This passage was published in the form of "The Great Man's Instruction" after the Ninth National Congress. "One is not afraid of suffering, and the other is not afraid of death" then swept the country in the form of slogans and became a popular discourse for political mobilization and morale.
