Cultural Revolution was an ideological and revolutionary mass campaign in China .It aimed at changing the country’s traditional values and replace them with chairman Mao’s thinking. Mao propagated that the country should  have to get rid of the “Four Olds” ,namely “old ideas, old customs , old culture , and old habits” . It was also an attack on China’s intellectual elite. The revolution and destruction of the old China were carried out by a mass of students with the encouragement of Mao. The student group was called the Red Guards,which were a group of militant students and to attack all traditional values and to publicly criticize party officials .The Gang of Four was composed of four Chinese Communist Party officials. They rose to power during the last stage of  Cultural Revolution.The gang’s members included Mao Zedong’s last wife Jiang Qing, Zhang Chunqiao, Yao Wenyuan, and Wang Hongwen. During the Cultural Revolution, the Gang of Four represented the leftist political faction within the CCP. Jiang Qing was the main leader in the Gang of Four. She staged revolutionary operas during the Cultural Revolution and met with the Red Guards.With the her direction in operas and ballets with communist and revolutionary content ,it was a part of effort to transform China’s culture. She also attempted to reform the Beijing Opera in particular to dominate the Chinese arts.Moreover, she continually worked to undermine political rivals, such as launched the ‘Criticise Lin Biao’ propaganda campaign in late 1973, attempting to link Lin Biao with the highly popular Zhou Enlai.Before Mao’s death, the Gang of Four also controlled many of China’s political institutions, including the media and propaganda.    The Gang of Four, together with the disgraced general Lin Biao who died in 1971, were labeled as the two major “counter-revolutionary forces” of the Cultural Revolution afterwards . On 6 October 1976, shortly after the death of Mao, Hua removed the Gang of Four from political power by arranging for their arrests in Beijing. In Winter 1980-1981, the gang of four were put on trial. They were officially blamed by the Chinese government for the societal chaos that occurred during the ten years of turmoil.The courtroom drama played out on TV.The gang of four  were sentenced to prison after Mao’s death.Their downfall brought about major celebrations on the streets of Beijing and marked the end of a turbulent political period in China.However, their fall did not amount to a rejection of the Cultural Revolution as such. It was organised by the new leader, who was Mao’s designated successor, Hua Guofeng, and others who had risen during that period., Hua Guofeng had also taken over all the formal roles of leadership. B)     Quotations of leaders1.
