曹植
Yang Xiu was a close friend of Cao Cao's son, Cao Zhi, and became involved in the succession struggle between Cao Zhi and his brother Cao Pi. Yang Xiu's close links with Cao Zhi caused him misfortune during Cao Zhi's occasional misbehaviour such as the incident in Ye city, where Cao Zhi drunkenly rode through the gate reserved for only the emperor. But the final blow was when Yang Xiu was discovered to have leaked the council's discussion agenda to Cao Zhi so that his friend could prepare beforehand and impress Cao Cao. Because of this and remembering his connection with Yuan Shu, Cao Cao had Yang Xiu executed.
