Yang Yi
Yang Yi once told Fei Yi: "When the Imperial Chancellor died, I should have brought along my men and defected to Wei if I knew I'd end up in this situation today! I deeply regret but there's nothing I can do now." Fei Yi secretly reported Yang Yi to the Shu government. As a result, in 235 Yang Yi was demoted to the status of a commoner and exiled to Hanjia Commandery (漢嘉郡; around present-day Lushan County, Sichuan), where he committed suicide later.
