Teacher: Now, understand the problem? Solve this instance: Question: When was the author who described a communist society born? Passage:The term entered common usage during the era of Deng Xiaoping and was largely associated with Deng's overall program of adopting elements of market economics as a means to foster growth using foreign investment and to increase productivity (especially in the countryside where 80% of China's population lived) while the Communist Party of China retained both its formal commitment to achieve communism and its monopoly on political power. In the party's official narrative, socialism with Chinese characteristics is Marxism–Leninism adapted to Chinese conditions and a product of scientific socialism. The theory stipulated that China was in the primary stage of socialism due to its relatively low level of material wealth and needed to engage in economic growth before it pursued a more egalitarian form of socialism, which in turn would lead to a communist society described in Marxist orthodoxy.
