Quán Cóng appellation Zǐhuáng was a Wú prefecture Qiántáng man. His father Róu in Hàn Emperor Líng’s time was nominated Filial and Incorrupt, filling vacancy as Secretariat Documents Cadets Right Deputy, in Dǒng Zhuó’s chaos left office and returned, the province recruited him as Separate Harness Attending Official, Imperial Order letter then appointed him Kuàijī East Division Commandant. Sūn Cè arrived at Wú, Róu raised troops to first join, Cè memorialized Róu as Dānyáng Commandant. When Sūn Quán became Chariots and Cavalry General, appointed Róu as his Chief Clerk, transferred to Guìyáng Administrator. Róu once sent Cóng to carry rice of several thousand hú to Wú, to trade in the market. Cóng arrived, scattered and used it all, and with empty boat returned. Róu was greatly furious, Cóng bowed head and said: “I foolishly believed market trading was not urgent, and the scholar officials are about to have misfortunes of collapse, and therefore recklessly gave out support, and did not send report.” Róu then was impressed with him. (1) At the time the servicemen of the central provinces fled the chaos and went south, those that relied on Cóng for housing were in the hundreds, Cóng emptied his house to give and relieve, sharing in having and lacking, and therefore his prominent name spread far and near. Later Quán appointed him Exerting Authority Colonel, awarded troops of several thousand men, sent to suppress Shānyuè. Therefore he opened recruitment, obtaining elite troops of over ten thousand men, going out to garrison Niúzhǔ, gradually promoted to Assistant General.
- (1) Xú Zhòng’s comment states: By ritual, the son in serving father is without personal wealth, and also does not dare personally give out, in order to avoid infringing on superiors. To discard mandate and take control of wealth in order to seek reputation, was not exhaustive of the propriety of father and son.
- Your Servant Sōngzhī believes: Zǐlù asked: “Have you heard of this conduct?” The master said: “There were fathers and elder brothers present.” Cóng then scattering his father’s wealth, truly was not a son’s way, however the servicemen types in spreading command, worry in morning and night, are expedient in their lightness or heaviness, to put first another’s emergency, this also was of the sort as Féng Nuǎn’s righteousness in the market and Jí Àn’s rousing and rescuing, to completely call it seeking reputation, perhaps betrays this heart.
Jiàn’ān Twenty-Fourth Year , Liú Bèi’s officer Guān Yǔ besieged Fán and Xiāngyáng, Cóng sent up memorial explaining a plan that [Guān] Yǔ could be suppressed, [Sūn] Quán at the time was already with Lǚ Méng secretly discussing attacking him, feared the matter had leaked, and therefore dismissed Cóng’s memorial and did not answer. Reaching to the capture of [Guān] Yǔ, [Sūn] Quán set up liquor at Gōng’ān, and turned to say to Cóng: “You previously explained this, though I did not answer it, today’s triumph also was your achievement.” Therefore enfeoffed as Yánghuá precinct marquis.
Huángwǔ Inaugural Year , Wèi with boats and army greatly set out against Dòngkǒu, [Sūn] Quán sent Lǚ Fàn to command the various officers to resist them, the army camps faced one another. The enemy repeatedly with light ships raided and struck, Cóng always wore armor and grasped weapon, looking out without rest. Shortly after this, the enemy of several thousand people set out into the Jiāng, Cóng struck and defeated them, beheading their General Yǐn Lú. Promoted Cóng to Soothing South General, advanced fief to Qiántáng marquis. Fourth Year , Lent Staff as designate Jiǔjiāng Administrator.
Seventh Year , [Sūn] Quán arrived at Huán, sent Cóng with Assisting the State General Lù Xùn to strike Cáo Xiū, defeating him at Shí’tíng. At the time Dānyáng, Wú, and Kuài’s mountain peoples repeatedly became bandits, attacking and destroying various counties. [Sūn] Quán divided the three prefecture’s rugged terrain to form Dōng’ān prefecture, Cóng designated Administrator. (1) He arrived, made clear reward and punishment, enticed surrenders and attachment, and within a few years, obtained over ten thousand people. [Sūn] Quán summoned Cóng back to Niúzhǔ, abolished Dōng’ān prefecture. (2) Huánglóng Inaugural Year , promoted Guard General, Left Protector of the Army, Xú province Governor, (3) bestowed a princess.
- (1) Wú lù states: Cóng at the time governed at Fùchūn.
- (2) Jiāngbiǎo zhuàn states: Cóng returned, passed through Qiántáng, repaired and sacrificed to the graves, his flags and banners and canopies dazzling through his old hometown, invited and met with the town people he had known his whole life, his clansmen and six relations, giving out and scattering and sharing, over a thousand of ten thousands, his home land by this thrived.
- (3) Wú shū states: Previously, Cóng as an officer was extremely brave and decisive, in matching enemy and facing disaster, he would exert himself without regard to his body. When he became a commander, he raised authority and maintained severity, every time managing the army, he always established plans, not striving for small gains.
- Jiāngbiǎo zhuàn states: [Sūn] Quán sent his son [Sūn] Dēng to go out on campaign, had already sent out the army, going to Ānlè, of the various minsiters none dared remonstrate. Cóng secretly memorialized saying: “From since the ancients the Heir-Apparent has never once accompanied campaign, therefore following is called Succoring the Army, defending is called Supervising the State. Now the Heir-Apparent going out east, is not the ancient regulations. Your servant humbly has worries and doubts.” [Sūn] Quán at once followed this, ordering [Sūn] Dēng to turn back the army. The commentators all believed Cóng had a great minister’s integrity.
Jiāhé Second Year , commanded infantry and cavalry of fifty thousand to campaign against Lù’ān, Lù’ān’s people all scattered and fled, the various officers wished to divide troops to capture them. Cóng said: “To ride into danger depending on luck and act without certain completion, is not of the country’s overall form. Now to divide troops to capture people, the gains and losses are both half, how can it be called complete? It lets go what is gained, and yet is not enough to weaken the enemy and assist the state’s expectations. If there is a chance encounter, the losses would not be small, to share in obtaining punishment, I Cóng would rather personally receive it, and not dare for a lucky achievement fail the state.”
Chìwū Ninth Year , promoted to Right Marshal-in-Chief, Left Master of the Army. As a person he was respectful and obedient, skilled in following appearances and accepting admonishments, his words were never once cutting and obstinate. Previously, [Sūn] Quán was about to besiege Zhūyá and Yízhōu, all first asked Cóng, Cóng said: “With the sagely court’s authority, where could it go and not overcome? However it is an alien region and foreign land, cut off and obstructed by sea, water and land and air are poisonous, from since the ancients it has been when troops enter the people leave, it certainly will produce diseases, and turning around in the cross-contamination, those that go will fear they will not be able to return, and how ca the captured be numerous in coming? To decrease the troops on the Jiāng’s bank, to hope for a ten thousand to one profit, I your foolish servant am yet not at ease.” [Sūn] Quán did not listen. The army went out for a year, the soldiers suffered epidemic and the dead were eight to nine out of ten, [Sūn] Quán deeply regretted it. Later in speaking of it, Cóng replied saying: “At that time, of the various ministers there were those that did not remonstrate, I your servant believe it disloyalty.”
Cóng was both a relative [by marriage] and heavily valued, his clansmen and junior relatives all were immersed in favor and nobility, the bestowals accumulated thousands of gold, however he was yet modest in receiving servicemen, his countenance was without proud expression. Twelfth Year  he died, his son Yì succeeded. Later he inherited the enterprise and command of troops, rescuing Zhūgě Dàn at Shòuchūn, went out of the city and was first to surrender, Wèi appointed him Pacifying East General, enfeoffed Línxiāng marquis.
