Zhong Hui
Initially, when Sima Zhao wanted to put Zhong Hui in charge of leading the Wei army to conquer Shu, Shao Ti warned him that Zhong Hui might rebel against Wei because he was in command of an army of thousands, was single, and had no family to worry about. Sima Zhao laughed and said he understood Shao Ti's concern very well, but chose to let Zhong Hui lead the Wei army because he had faith in Zhong's ability to conquer Shu. He also predicted that Zhong Hui would not succeed even if he rebelled because of two reasons. First, the people of Shu would be fearful after seeing how their state had been conquered, and hence would not help Zhong Hui. Second, the Wei forces would be exhausted after the campaign and want to return home, so they would not support Zhong.
