张闻天
On November 12, 1960, he took up the job as a researcher for the Institute of Economics at Department of Philosophy and Social Sciences in Chinese Academy of Sciences, and dealt with the research on socialist economic development theories. He went to Jiangsu, Zhejiang, Shanghai, and Hunan to conduct a social survey. After the survey was over, he wrote a report “Suggestions on Market Trade”. During the Eighth Plenary Session of the Eighth Central Committee, Mao Zedong again criticized Peng Dehuai, Zhang Wentian, Xi Zhongxun and others. After the meeting, Zhang Wentian was deprived of the right to participate in all Central Committee's meetings and read any document from the Central Government. Afterwards, Zhang Wentian again put forward "A Duality of Production Relations Theory". On October 1, Zhang Wentian took part in the celebration of the National Day and went up to the Tiananmen Gate Tower with Mao Zedong to have a conversation.
