Lú Yù appellation Zǐjiā was a Zhuō prefecture Zhuō man. His father Zhí had fame in the world. (2) Yù at ten years was fatherless, it happened his home province was in chaos, and his two older brothers died in the troubles. Right as Yuán Shào and Gōngsūn Zàn engaged troops, Yōu and Jì were in famine, he cared for his widowed older brother’s wives and fatherless older brother’s sons, for learning and conduct met with praise. When Emperor Wén [Cáo Pī] was Five Offices General, he summoned Yù and installed him in the Below Gate Bandit Department. Cuī Yǎn nominated him as Jì Province Registrar. At the time Heaven’s Under was roughly starting [to settle], many had fled, and therefore heavy were the laws on deserting soldiers, punishment reaching to wives and children. A deserted soldier’s wife Bái Děng, her husband had been at home several days, and she had not with her husband met each other, the Minister Judge memorialized to discard [execute] in market. Yù contested this saying: “A woman’s feelings, is by meeting and afterward relationship is formed, completing marriage and relationship is heavy. Therefore the Shī says: ‘Not yet meeting gentleman, my heart is pained and grieved; also just seeing step, my heart then is calmed.’ Also the Lǐ ‘A woman not yet in the shrine meeting and dying, returns to be buried as the woman’s clan’s group, because she has not yet become a wife.’ Now Bái Děng has the grief of not yet meeting, in dying has the pain of not being a wife, but the officials discuss wishing to wantonly use capital punishment, then it is like being the same as after sharing marriage cup, what punishment is to be applied? Moreover the Jì states: “Attached follows lenience,’ saying that the punishment of an attached person, uses lenience as comparison. Also the Shū says ‘Rather than kill those without crime, better to fail to not be thorough.’ One fears it is too heavy. If Báiděng had all received betrothal gift, and already entered gate hall, punishing her would be possible, killing her is heavy.” Tàizǔ said: “Yù’s argument is correct. Also his citing of classic canon with intention, causes me to sigh.” Because of this he became Chancellor’s Law Department Consultant Director Scribe, transferred to Left Department Consultant Director Scribe.
- (1) Xù Hàn shū states: Zhí appellation Zǐgàn. When young he served Mǎ Róng, with Zhèng Xuán sharing gate as mutual friends. Zhí was resolute and had great integrity, always sighing with ambition to save the world, he did not improperly cater to appearances, and did not answer the province’s and prefecture’s summons.

Gradually promoted to Attendant Internal, Secretariat Documenter. When Zhāng Jué rose up, appointed Zhí as North Internal Cadet General to campaign against [Zhāng] Jué, was not successful and was punished. Shortly afterward, again became Secretariat Documenter. Zhāng Ràng seized the young Emperor and fled to Xiǎopíng jīn, Zhí hand wielded sword to repeatedly rebuke [Zhāng] Ràng and the rest, [Zhāng] Ràng and the rest all put down weapons, shed tears and apologized for guilt, and therefore killed themselves. Dǒng Zhuó discussed intention to depose the Emperor, of the masses none dared reply, Zhí alone uprightly spoke, the story is in Zhuó’s biography. Zhí due to old age and illness left position, lived in seclusion at Shànggǔ’s Jūndū mountain, Chūpíng Third Year  died. Tàizǔ campaigned north against Liǔchéng, passed Zhuō prefecture, Order announced to the Administrator stating: “Former North Internal Cadet General Lú Zhí,’s fame was known Within the Seas, in scholarship he was a classicist exemplar, a model for scholars, and so was the state’s evergreen shield. In the past King Wǔ entered Yīn, enfeoffed Shāngróng’s village, Zhèng mourned for Zǐchǎn and Zhòngní shed tears. I arrive at this province, and commend this remaining air. In the Chūnqiū‘s principles, the posterity of a worthy, is different from other men. Respectfully send deputy official to repair the grave tomb, and also deliver meager libations, to make manifest his virtue.” Zhí had four sons, Yù was the youngest.
When Wèi state was established, became Appointment Division Cadet. When Emperor Wén ascended, transferred to Yellow Gate Attendant Cadet, sent out as Jǐyīn Chancellor, Liáng and Qiáo two prefectures’ Administrator. The Emperor because Qiáo was his old hometown, therefore greatly relocated people to populate it, forming garrison-farms. But Qiáo’s lands were stony and barren, the hundred surnames were destitute, Yù mourned for this, and sent up memorial to relocate people to Liáng state where it was rich and fertile, disappointing the Emperor’s intentions. Though he listened to what Yù memorialized, his heart yet hated him, and therefore demoted Yù, sending him to lead the transferred people as Suīyáng Managing Agriculture Colonel. Yù’s heart was in profiting the people, he personally oversaw them, choosing to occupy them in beautiful farms, the hundred surnames depended on this. Promoted to Ānpíng and Guǎngpíng Administrator, wherever he was he had kind influence.
Qīnglóng Second Year , entered as Attendant Internal. Before this, Cavalier Regular Attendant Liú Shào received Imperial Order to settle the law, and had not yet finished. Yù sent up discussion of the meanings of ancient to present law systems, believing law should be unified and standard, and should not have two ends, to cause treacherous officials to be able to indulge feelings. When Attendant Internal Gāotáng Lóng repeatedly about Palace Resident affairs sternly remonstrated, the Emperor was not pleased, Yù advanced saying: “Your servant has heard that when the lord is enlightened then ministers are upright, the ancient sage kings feared not hearing of their mistakes, and therefore there was encouragement of daring to remonstrate. The close ministers exhaustively admonishing, in this then we your servants do not match [Gāotáng] Lóng. [Gāotáng] Lóng this scholar, is to be called as wildly upright, Your Majesty should tolerate him.” He was in office for three years, and had many varied arguments. Imperial Order said: “Government officials ordered by talent, is what the sagely emperor finds difficult, there must be good assistants, to advance the possible and replace the bad. Attendant Internal Yù in natural character is chaste and assured, heart just and body upright, can be said to clearly tested as having achievement, and is one untiring in his position. Thus appoint Yù as Appointment Division Secretariat Documenter.” Had Yù himself choose his successor, saying: “If it is one like you it can be.” Yù nominated Regular Attendant Zhèng Chōng, the Emperor said: “Wénhé, I personally know him, again nominate someone I have not yet heard of.” Therefore nominated Ruǎn Wǔ, Sūn Yōng, the Emperor therefore employed [Sūn] Yōng.
Before this Zhūgě Dàn, Dēng Yáng and others had fame and acclaim, there was complaint of the Four Intelligent and Eight Comprehensive, the Emperor hated them. At the time of nominating an Internal Documents Cadet, Imperial Order said: “Obtaining the person or not is up to Sir Lú. The selection is not to take one with reputation, reputation is like drawing on the ground to create a pastry, it cannot be eaten.” Yù replied saying: “Reputation is not sufficient to deliver exceptional people, but it can be used to obtain ordinary servicemen. Ordinary servicemen fear teachings and admire excellence, and afterward have reputation, it should not be hated. I your foolish servant am not sufficient to recognize exceptional people, and also the manager exactly by following reputation case standards serves their duty, it only should be after an examination. Therefore the ancients applied memorials as speech, enlightened testing as achievement. Now the methods of investigating merits are deposed, and by defamation and acclaim they mutually advance and withdraw, therefore the true and false are mixed together, the empty and real mutually immersed.” The Emperor accepted this speech, and at once Imperial Ordered to create examination methods. It happened the Excellency over the Masses was vacant, Yù recommended resident scholar Guǎn Níng, the Emperor was not able to employ him. Again asking for another, Yù replied saying: “Honest sincerity utmost in conduct, then is Grand Internal Grandee Hán Jì; bright uprightness and pure straightness, then is Colonel Director of Retainers Cuī Lín; chaste firmness pure and complete, then is Minister of Ceremonies Cháng Lín.” The Emperor then employed [Hán] Jì. Yù in electing people, first nominated by character and conduct, and afterward speech and talent. Yellow Gate Lǐ Fēng once about this asked Yù, Yù said: “Talent is how to be excellent, and therefore great talent achieves great excellence, small talent achieves small excellence. Now to praise them as having talent but not able to be excellent, is talent not matching function.” [Lǐ] Fēng and the rest accepted this speech.
The King of Qí succeeded the throne, bestowed noble rank as Marquis Within the Passes. At the time Cáo Shuǎng held power and was about to set up his faction, relocated Yù to Deputy-Director, having Attendant Internal Hé Yàn succeed Yù. Shortly after this, sent out Yù as Minister of Justice, Director of Retainers Bì Guǐ also unjustly memorialized to dismiss him from office, the masses discussed and many contested it, and so appointed Yù as Minister of Merits. [Cáo] Shuǎng and the rest were arrested, Grand Tutor Sīmǎ [Yì] Xuān-wáng sent Yù to act as Colonel Director of Retainers, managing their imprisonment.
