叶群
When the Cultural Revolution occurred in 1966, Zhou Enlai sent Sun and her husband to work in Daqing to protect them from political persecution, but Jiang Qing and Ye Qun conspired to have Sun secretly arrested in 1968 while visiting Zhou Enlai in Beijing. Sun was sentenced without trial, and was tortured in a secret prison for several months before dying. After Sun died, Jiang Qing made arrangements for Sun's body to be cremated before an autopsy could be performed, and for her ashes to be disposed of before Zhou or Sun's other relatives could take possession of them. Sun's husband was not informed of Sun's death until his release, in 1975.
