Four Modernizations
Following the fall of Lin Biao, Minister of National Defense and Mao's heir apparent, in 1971, the atmosphere for intellectuals began to improve. Under the aegis of Zhou Enlai and later Deng Xiaoping, many intellectuals were restored to their former positions and warily resumed their pre-Cultural Revolution duties. In January 1975 Zhou Enlai set out his ambitious Four Modernizations program and solicited the support of China's intellectuals in turning China into a modern industrialized nation by the end of the century.
