No reactionary class will ever step down from the stage of history of its own accord. When the revolution touched that portion of power usurped by the bourgeoisie, the class struggle became all the more acute. After Liu Shao-chi's downfall, his revisionist clique and his agents in various places changed tactics which were "Left" in form but Right in essence such as "suspecting all" and "overthrowing all", in a futile attempt to go on hitting hard at the many and protecting their own handful. Moreover, they created splits among the revolutionary masses so as to protect themselves. When these schemes were shattered by the proletarian revolutionaries, they launched another frenzied counter-attack, that is, the adverse current lasting from the winter of 1966 to the spring of 1967.

This adverse current was directed against the proletarian headquarters headed by Chairman Mao. Its general programme boiled down to this: to overthrow the decisions adopted by the Eleventh Plenary Session of the Eighth Central Committee of the Party, reversing the verdict on the overthrown bourgeois headquarters headed by Liu Shao-chi, reversing the verdict on the bourgeois reactionary line, which had already been Thoroughly repudiated and discredited by the broad masses, and repressing and retaliating on the revolutionary mass movement from surging forward.
