Ji Kang
Ji Kang was highly critical of Confucianism and challenged many social conventions of his time, provoking scandal and suspicion. He married Cao Cao's granddaughter (or great-granddaughter according to some). Ji Kang assumed a post under the Cao Wei state, but official work bored him. When the regent Sima Zhao came to power, he offered Ji Kang a civil position, but Ji Kang insolently rejected Sima Zhao's envoy Zhong Hui. When one of Ji Kang's friends was imprisoned on false charges, Ji Kang testified in his defense, but both were sent to jail. At Zhong Hui's urging, Sima Zhao sentenced Ji Kang to death. Three thousand scholars petitioned for his pardon, but his enemies were implacable. Before his execution, Ji Kang is said to have played one last melody on the guqin, a swan song forever lost.
