Сыма Чжао
It is believed that Sima Zhao decided to spare Zhong Jun and Zhong Chan because Zhong Yu once warned him that Zhong Hui was manipulative and should not be placed in positions with great power. Sima Zhao laughed, praised Zhong Yu for his honest advice, and promised that he would spare Zhong Yu's family if Zhong Hui really did commit treason.
