Jia Kui

The envoy who defuses the succession crisis with two rebukes: 'there is an eldest son to a house, and an heir-apparent to a state' — and at the gates, 'you come as a mourner or as a rival claimant?' Cao Zhang's escort turns back.

Right twice and punished for it. Warns at court that Zhou Fang's submission 'may be understood in two ways' and that a man so wise and crafty is very unlikely to desert. Sent along anyway, he rides to Cao Xiu's camp to warn him again, meets the sneer 'You mean you want to share in my victory', and answers with the precedent that exactly fits: Yao Li cut off his own arm as a pledge of loyalty before assassinating Prince Qing Ji — 'Mutilation is no guarantee.' Cao Xiu orders him put to death for ill-omened words; the officers get him reprieved, but his troops are left in reserve. He then saves the man who sidelined him, meeting the rout on the Jiashi road and covering it by planting flags and banners through the trees and by-paths until Xu Sheng takes the country for full of ambushes and calls off the pursuit.

Named in passing only, and long dead, as the whole of Zhuge Dan's case against his son: 'You are a son of Jia Kui of Yuzhou, and your family have received the bounty of Wei. Yet you dare speak of rebellion!'
