In 1966, just as China basically completed its task of adjusting the economy and began to implement the third five-year plan for the development of the national economy, the "Cultural Revolution" took place.
The "Cultural Revolution" was launched and led by Comrade Mao Zedong. The starting point for his launch of the "Great Revolution" was to prevent the restoration of capitalism, safeguard the purity of the party, and seek China's own path of building socialism. However, his erroneous estimation of the political situation of the party and the country at that time has developed to a very serious extent.
The "Cultural Revolution" went through three stages from the launch of the 9th National Congress of the Communist Party of China in April 1969 to the 10th National Congress of the Communist Party of China from the ninth to the end of August 1973 and the end of October 1976. The Ninth National Congress of the Communist Party of China strengthened the status of Lin Biao, Jiang Qing, Kang Sheng and others in the central government, and legalized the wrong theory and practice of the "Cultural Revolution." The incident of the Lin Biao incident in September 1971 objectively declared the failure of the "Cultural Revolution" theory and practice, but the CCP's Tenth National Congress continued to make the "Left" mistakes of the Nine Majors and further strengthened the forces of the Jiangqing counter-revolutionary group. After the death of Mao Zedong in September 1976, Jiang Qing, Zhang Chunqiao, Yao Wenyuan, and Wang Hongwen stepped up their seizures of the party and the country's highest leadership. In October of the same year, the Political Bureau of the CPC Central Committee implemented the will of the party and the people and smashed the "Gang of Four" in one fell swoop, thus terminating the disaster of the "Cultural Revolution."
Practice has proved that the "Cultural Revolution" is not and cannot be revolutionary or social progress in any sense.
During the "Cultural Revolution" period, the struggle between the party and the people and the "Left" mistakes and the struggles of Lin Biao and Jiang Qing counter-revolutionary groups, although difficult and tortuous, have never stopped. During this decade, China’s national economy has still made progress and foreign work has opened up a new situation. However, without the "Cultural Revolution", China's socialist cause will achieve much greater achievements.
