Wang Su

Writes the memorial that ends the AD 230 invasion. Argues from the supply problem first ('when supplies have to be conveyed a long distance, the soldiers are starved; if they have to gather brushwood before they can cook, then the army is not full fed'), then from the month already spent getting half through the valley with the fighting soldiers doing road work, then from precedent - King Wu of Zhou turning back at the pass, Cao Cao and Cao Pi stopping at the river against Sun Quan - 'Did they not recognize limitations and act accordingly?'

Grand Commander, and the first to try to teach the new emperor his manners: when Cao Mao returns the assembled officers' salutations at the Nanye Gate, 'The ruler ought not to return these salutations,' said Grand Commander Wang Su - and is answered 'I also am a minister and must respond.'

Grand Commander, and the chapter's most-consulted head. Supplies the Lu Meng precedent for neutralising the Huai garrisons through their families; then, after Sima Zhao ignores the order to stay at Xuchang and camps on River Luo, tells Cao Mao the only safe course - 'Sima Zhao has succeeded the office of his late brother. It is well that Your Majesty should placate him with a new title' - and carries the edict that makes him Regent Marshal.

Named as the father of Sima Zhao's wife - 'The wife of Sima Zhao was the daughter of Wang Su' - and so the maternal grandfather of the founder of Jin.
