[Zhōng] Yù appellation Zhìshū. Aged fourteen he became Cavalier Attendant-Cadet, was clever and quick and conversed and laughed, and had his father’s [Zhōng Yáo] manner. At the beginning of Tàihé , Shǔ Chancellor Zhūgě Liàng besieged Qíshān, Míng-dì [Cáo Ruì] wished to campaign west, and Yù sent up memorial: “In strategy esteem [planning in] headquarters for victory, in achievement esteem [planning in] tents, do not go down from above the palace hall, and decide victory a thousand lǐ away. The Imperial Chariot should defend the central lands, to be the assistant to the Four Corner’s authority. Now the main army campaigns west, and though it has a hundredfold authority, its costs to Guānzhōng, are already massive. Moreover in flourishing heat sending out the army, poets may esteem, but it is not what the time for your Honor to move.”
He was transferred to Yellow Gate Attendant-Cadet. At the time there was great raising of Luòyáng Palaces, the Imperial Carriage visited Xǔchāng, and the realm Under Heaven held Court at Xǔchāng. Xǔchāng was packed and narrow, and so south of the city was set tent to serve as Palace, with preparations for entertainment, and the people suffered labor conscription. Yù remonstrated: “The season is inappropriate, the treasury is empty, and if there is to be something like this, it can wait for a prosperous year.” He also sent up: “It is appropriate to reopen uncultivated land within the Passes, to allow the people to devote their strength to agriculture.” The matter was therefore put into effect.
During Zhèngshǐ [240-249] he became Cavalier Regular Attendant. General-in-Chief Cáo Shuǎng in midsummer raised the army to campaign against Shǔ, Shǔ resisted and defended, and the army could not advance. [Cáo] Shuǎng wished to increase troops, Yù sent him letter: “I humbly believe the strategy for victory, is to not face arrows and stones. A ruler’s troops, campaigns without battle. Truly spears and axes can take the southwest, withdrawing is enough to take the enemy. We need not imitate Wú Hàn at Jiāngguān, or Hán Xìn at Jǐngxíng. Seeing opportunity and advancing, knowing difficulty and retreating, is governance since ancient times. May you lord consider this!” [Cáo] Shuǎng without achievement returned. Later he lost [Cáo] Shuǎng’s favor, was transferred to Attendant Atternal, and sent out as Administrator of Wèijùn. When [Cáo] Shuǎng was executed, he entered as Censorate Central Deputy, and Attendant Internal Minister of Justice. The practice that, though the father should be gone, the sons could on his behalf contest slander, and when scholars become Marquis, and his wife could not again marry, was started by Yù.
During Zhèngyuán [254-256], Guànqiū Jiǎn and Wén Qīn rebelled. Yù Wielding Staff of Authority went to Yáng and Yù Provinces to issue amnesty, and inform the scholars and people, returned and became Secretariat.
Zhūgě Dàn rebelled, and General-in-Chief Sīmǎ [Zhāo] Wén-wáng discussed personally going to Shòuchūn to suppress [Zhūgě] Dàn. It happened that Wú chief general Sūn Yī led his army to surrender, and some believed: “Wú newly has strife, and certainly cannot again send out army. The eastern troops are already many, so you can wait for later reports.” Yù believed: “Discussing matters and judging the enemy, should use oneself as the standard. Now [Zhūgě] Dàn has raised the lands south of the Huái to join with Wú state, and those Sūn Yī leads do not number one thousand, the troops not more than three hundred. Wú’s loss is very little. If the siege of Shòuchūn is not resolved, and Wú state’s internal matters become secure, then it is not certain that they cannot set out.” The General-in-Chief said: “Agreed.” Therefore he led Yù and went.

- Your Servant Sōngzhī believes: Zhūgě Dàn raised the Huái’s south to join Wú, Sūn Yī led three hundred men to join Wèi. Saying that Wú has strife, from the beginning was words without reason. Yù in this comment, how is it enough to be praised?
When the Huái’s south was pacified, he became Inspector of Qīngzhōu, also General of the Rear, promoted to Regional Commander of Xúzhōu’s military affairs, Lent Staff, and then transferred to Regional Commander of Jīngzhōu.
Jǐngyuán fourth year  he died, posthumously promoted to General of Chariots and Cavalry, posthumous name Huì-hóu “Gentle Marquis.” His son Jùn succeeded.
Yù’s younger brother [Zhōng] Huì has his own biography [in SGZ 28].
