叶群
During the Cultural Revolution, tensions between Jiang Qing and Lin Biao's faction escalated. According to Party documents, in early 1971, it was Ye Qun who asked her son Lin Liguo to assassinate Mao Zedong during his trip to Shanghai, as part of the plan known as Project 571. The attempt failed, as Mao suddenly changed his plans and returned to Beijing on the evening of September 12. This led to Ye Qun believe that the plan had been exposed. Following the failure of their plans, Ye Qun, Lin Liguo and Lin Biao decided to flee, but their daughter Lin Liheng revealed their escape plan to Premier Zhou Enlai.
