Lǚ Dài appellation Dìnggōng was a Guǎnglíng Hǎilíng man. He became a prefecture and county official, and to flee the chaos crossed south [of the Jiāng].
Sūn Quán took over affairs , Dài visited his headquarters, and was sent out to defend as Assistant of Wú [county]. Quán personally inspected the county storehouses and bound prisoners, and the Chiefs and Assistants all came to meet. Dài’s governance methods and answers to questions were deeply in agreement with Quán’s thoughts, and he was summoned and installed as a Diarist, sent out to fill vacancy as Chief of Yúyáo, summoned to recruit the elite and strong, obtaining over a thousand men. Kuàijī’s Dōngyě five counties rebel Lǚ Hé, Qín Láng, and others caused chaos. Quán appointed Dài as Commanding Army Colonel, with General Jiǎng Qīn and others commanded troops to suppress them, and thereupon captured Hé and Láng, and the five counties were pacified. He was appointed Internal Gentleman-General Manifesting Faith. (1)
- (1) Wúshū states: Jiàn’ān sixteenth year , Dài commanded Gentleman-General Yǐn Yì and others, with troops 2000 men went west to entice Hànzhōng rebel commander Zhāng Lǔ and arrived at Hànxīng’s Jiǎnchéng. Lǔ was suspicious and cut off the roads, and the affairs and plans could not be set up. Quán therefore summoned Dài back.
Jiàn’ān twentieth year  he commanded Sūn Mào and others ten Generals to follow in capturing Chángshā, three commanderies. Also Ānchéng, Yōu, Yǒngxīn, Chálíng, four counties had officials together enter Yīnshānchéng, gathering an army to resist Dài. Dài attacked and besieged, they at once surrendered, and the three commanderies were subdued and settled. Quán left Dài to defend Chángshā.
Ānchéng Chief Wú Dàng and Internal Gentleman-General Yuán Lóng and others responded to Guān Yǔ, and again rebelled. [Wú] Dàng occupied Yōu county, and [Yuán] Lóng was at Lǐlíng. Quán sent General Across the Jiāng Lǔ Sù to attack Yōu. [Wú] Dàng broke through [the encirclement] and fled. Dài attacked Lǐlíng, thereupon captured and beheaded [Yuán] Lóng, and was promoted to Administrator of Lúlíng.
Yánkāng Inaugural Year , he succeeded Bù Zhì as Inspector of Jiāozhōu. He arrived in the province, Gāoliáng rebel commander Qián Bó asked to surrender. Dài therefore followed regulation and appointed Bó as Gāoliáng western part’s Commandant. Also Yùlín’s foreigner bandits attacked and besieged the commandery and counties. Dài attacked and defeated them.
At the time Guìyáng and Zhēnyáng rebel Wáng Jīn gathered an army above Nánhǎi’s border, and led rebellion to do harm. Quán also ordered Dài to suppress them. He captured alive [Wáng] Jīn, delivered him to the capital, and the beheaded and captured alive were over ten thousand people. He was promoted to General Calming the South, with Staff of Authority, and fief as Marquis of a capital village.
Administrator of Jiāozhǐ Shì Xiè died. Quán appointed Xiè’s son Huī as General Calming the Distant, office as Administrator of Jiǔzhēn, and appointed Colonel Chén Shí to succeed Xiè. Dài memorialized to divide [Jiāozhōu] with the sea’s south three commanderies to form Jiāozhōu with General Dài Liáng as inspector, and the sea’s east four commanderies to form Guǎngzhōu, with Dài himself as Inspector. [Dài] Liáng with [Chén] Shí entered south, but Huī would not accept the order, and raised troops to garrison Hǎikǒu to resist Liáng and the rest.
Dài therefore sent up memorial asking to punish Huī’s crimes, and commanded troops 3000 men morning and night crossing the sea. Someone said to Dài: “Huī relies on favor accumulated over generations, the whole province attaches to him, and he is not to be taken lightly.”
Dài said: “Now though Huī harbors treacherous plans, but has never anticipated our troops’ arrival. If we secretly and lightly raise an army, we can catch him unprepared, and defeating him is certain. If we remain and do not hurry, it will cause him to become aware, hold to the city and firmly defend, the seven commanderies’ many barbarians will cloud together in answer, and even with someone wise, who could plan against them?”
Therefore he went, crossed Hépǔ, and with [Dài] Liáng together advanced. Huī heard Dài had arrived, and indeed was greatly shaken and afraid, did not know what to do, and at once led his brothers six men bare to the waist to welcome Dài. Dài beheaded and sent all of their heads. Huī’s chief Generals Gān Lǐ, Huán Zhì, and others led their officials and people to attack Dài. Dài exerted himself in attacking them and greatly defeated them, and was advanced in fief to Marquis of Pānyú. Therefore Guǎngzhōu was abolished, and again restored Jiāozhōu as before.
Dài had settled Jiāozhōu, and again advanced to suppress Jiǔzhēn, beheading and capturing tens of thousands. He also sent advisors south to announce the state’s cultivation, reaching beyond the border to the various rulers of Fúnán, Línyì, and Tángmíng, and each sent envoys to present tribute. Quán praised this achievement, and advanced him to General Defending the South.
Huánglóng third year , as the southern territory was quiet and settled, Dài was summoned back to camp at Chángshā Òkǒu. (1) It happened that the Wǔlíng foreigners stirred up trouble. Dài with Minister of Ceremonies Pān Jùn together suppressed and settled them.
- (1) Wáng Yǐn’s Jiāoguǎngjì states: Wú later again established a Guǎngzhōu, with Nányáng Téng Xiū as its Inspector. Someone told Xiū of shrimp feelers one zhàng [~2.3m] long. Xiū did not believe it. That person later went to the eastern sea, obtained a shrimp feeler four zhàng four chǐ [~10m] long, presented it to show Xiū, and Xiū therefore was convinced.
Jiāhé third year  Quán ordered Dài to take command Pān Zhāng’s officers and army, camp at Lùkǒu, later moved to Púqí.
Fourth year  Lúlíng rebels Lǐ Huán, Lù Hé, Kuàijī’s Dōngyě rebel Suí Chūn, Nánhǎi rebel Luó Lì, and others for a time together rose up. Quán again Imperial Ordered Dài to command Liú Zuǎn, Táng Zī, and others in separate divisions to suppress and attack, and [Suí] Chūn immediately first surrendered. Dài appointed [Suí] Chūn Assistant-General, sent him to command his army, and thereafter he became a full General. [Lǐ] Huán, [Luó] Lì, and others all met with beheading or capture, and their heads were sent to the capital.
Quán Imperial Ordered Dài: “Lì relied on rugged terrain to create rebellion, and brought on himself beheading; Huán was vicious and deceitful and erratic, had already surrendered and again rebelled, from beginning to end needed suppression, over the years was not captured. If not for your plans, who could take him? Your loyal and martial integrity, as a result increase in renown. The leading evil is already removed, great and small [rebels] are shaken and afraid, and the rest are minute sorts, and are swept to the ground. From now onward, the state has no worries looking south, the three commanderies are quiet, without alarm of apprehension. You also captured evil people to supply tax and conscription, and are worthy of sighs of admiration. Rewards not past one month is the state’s constant convention. In the system of what is suitable, you may choose something.”
Pān Jùn died. Dài succeeded Jùn in commanding Jīngzhōu written correspondence, with Lù Xùn together was at Wǔchāng, hence as Commander of Púqí. Shortly afterward, Liào Shì created rebellion, attacked and besieged cities, and Línglíng, Cāngwú, Yùlín commanderies were disturbed. Dài himself memorialized and at once went, under stars and at night hurrying on the road. Quán sent an envoy after to appoint Dài as Governor of Jiāozhōu, and sent the various Generals Táng Zī and others hurriedly in quick succession, attacking for one year and defeated them, beheading [Liào] Shì and all those he falsely appointed Administrator of Línhè Fèi Yáng and others, absorbed his followers, the commanderies and counties were all pacified. He again returned to Wǔchāng. At the time he was already eight years, but his body was always vigorous and energetic, and he personally oversaw affairs.
General Exerting Authority Zhāng Chéng with Dài wrote: “In the past Dàn and Shì supported Zhōu, the two southern songs were made [for them], and now it is just as you sir with Lù-zǐ [Lù Xùn]. In loyalty and diligence you mutually advance, in toil and modesty you mutually yield, your achievements with authority succeed, and enlighten following the Way, superior gentleman sigh at your virtue, low men are pleased with your greatness. In addition your written correspondence work is busy, guests come all day long, but though you are worn you do not leave affairs, toil without speaking of tiring, and I also know you when mounting a horse surpass others, do not need assistance in mounting, and in this way you sir surpass even Lián Pō, and in all these affairs you are quick. The Zhōuyì has the saying: ‘In ritual more respectful, virtue more great.’ How did you sir reach this greatness?”
When Lù Xùn died, Zhūgě Kè succeeded Xùn. Quán therefore divided Wǔchāng into two parts. Dài commanded the right [west] part, and from Wǔchāng went up to reach Púqí. He was promoted to General-in-Chief, and his son Kǎi was appointed Secondary Army Colonel, supervising soldiers at Púqí. When Sūn Liàng ascended, he was appointed Marshal-in-Chief.
Dài was pure in integrity and served public affairs, and wherever he was he was praised. Previously at Jiāozhōu, for successive years he did not send soldier’s pay home, and his wives and children were hungry and tired. Quán heard this and sighed, and criticized the various ministers: “Lǚ Dài sets out ten thousand lǐ, for the state is industrious in affairs, within his house is destitute, but I did not previously know. Trusted aides for ears and eyes, where is the responsibility?” Therefore he bestowed coins and grain and cloth and fabric, each year with a constant amount.
At first, Dài was close with Wú-jùn’s Xú Yuán, who was generous and had ability and ambition. Dài knew he could be successful, bestowed on him headscarf and robes, with him together talked and discussed, and afterward then recommended him, his office reaching Attendant Censorate. Yuán by nature was loyal and robust, liked to speak bluntly, and when Dài had faults, Yuán at once remonstrated, even in public would discuss this, and someone informed of this to Dài. Dài sighed and said: “That is why I esteem Déyuān.” When Yuán died, Dài wept for him with extreme grief, saying: “Déyuān was I, Lǚ Dài’s helpful friend. Now with this misfortune, how will I again hear of my errors?” Those who spoke of this praised him.
Tàipíng first year , ninety-six years he died, his son Kǎi succeeded. His will ordered a plain coffin, coarse headscarf and clothes, and the system of burial and procession, in affairs was to be sparing and frugal, and Kǎi all followed this.
