叶群
According to a modern standard Chinese narrative of Lin Biao's plot, Lin Biao became aware that Mao no longer trusted him after the Second Plenum of the 9th National Congress of the Communist Party of China in 1970, and he harbored a strong desire to seize supreme power. In February 1971, Lin and his wife Ye Qun (who was then a Politburo member) began to plot Mao's assassination. In March 1971, Lin Liguo held a secret meeting with his closest followers at an Air Force base in Shanghai. At this meeting, Lin Liguo and his subordinates supposedly drafted Project 571. Later that March, the group met again to formalize the structure of command following the proposed coup. The other major plotters were high-ranking military officers, including Zhou Yuchi, Yu Xinye, and Li Weixin.
