Abstract
Under the direction of the Party Central Committee led by Chairman Hua, the movement by the Party and the military rank and file and all the people of the nation to criticize and expose the "gang of four" is in full swing. It is very important to expose and criticize the fallacies of the "gang of four" politically, ideologically and theoretically in this struggle of great historical significance. Our sagacious leader Chairman Hua has pointed out: in the movement to criticize and expose the "gang of four," we "must expose and criticize the ultrarightist nature of the ‘gang of four's’ counterrevolutionary revisionist line and the manifestation of this line in various aspects and make criticisms from the philosophical, political-economic and scientific socialist theoretical viewpoints. We must wipe out the harmful effects of the ‘gang of four’ on all front lines through exposure and criticism"
