Cao Shuang
After returning to Luoyang, on 9 February 249 Cao Shuang was charged with plotting treason with the palace eunuch Zhang Dang (張當) and his associates He Yan, Ding Mi, Deng Yang, Bi Gui and Li Sheng. They were executed on the same day along with the rest of their families and relatives. Jiang Ji had attempted to persuade Sima Yi to spare Cao Shuang and his brothers in consideration of the meritorious service rendered by their father Cao Zhen, but Sima Yi refused. Lu Zhi (魯芝) and Yang Zong (楊綜), two of Cao Shuang's subordinates, had previously tried to stop Cao Shuang from surrendering to Sima Yi. After Cao Shuang was arrested, Lu Zhi and Yang Zong were also implicated and arrested as well. However, Sima Yi pardoned and released them.
