Pān Jùn appellation Chéngmíng was Wǔlíng Hànshòu man. When capped he followed Sòng Zhòngzǐ to receive study. (1)
- (1) Wúshū “History Book of Wú” states: Jùn as a man was clever and perceptive, answered questions with ease and reason, Wáng Càn of Shānyáng met and was impressed with him. Because of this he became well known, and became a prefecture Merit Officer.
When he was not yet thirty, Governor of Jīngzhōu Liú Biǎo recruited him as Jiāngxià division Advisor. At the time the Chief of Shāxiàn was corrupt and immoral, Jùn investigated and killed him, and the whole commandery was shaken and in awe. Later he became Magistrate of Xiāngxiāng, and for his government greatly had reputation. Liú Bèi governed Jīngzhōu, and appointed Jùn as Internal Manager Advisor. When [Liú] Bèi entered Shǔ, he remained to manage [Jīng] provincial matters.
 Sūn Quán killed Guān Yǔ and annexed the Jīng territory, appointed Jùn as Internal Gentleman-General Assisting the Army, to command troops. (1)
- Jiāngbiǎozhuàn “Biographies Beyond the River” states: [Sūn] Quán conquered Jīngzhōu, and all the officers and officials all came to join him, but [Pān] Jùn alone claimed illness and did not meet him. [Sūn] Quán sent someone with couch and carriage to invite him, but Jùn turned his face into his bed and would not rise, wept and mourned, his grief and crying uncontrollable. [Sūn] Quán comforted and spoke with him, calling him by his style: “Chéngmíng, in the past Guàn Dīngfù was a prisoner of war captured from Ruò, and [Chǔ] Wǔ-wáng appointed him as Military Master. Péng Zhòngshuǎng was a prisoner of war captured from Shēn, and [Chǔ] Wén-wȧng appointed him Magistrate Intendant. These two men were the foremost worthies of the officials of Jīng [i.e. Chǔ]. Though at first they were prisoners, later they were both promoted and employed, and became Chǔ’s famed ministers. You alone do not follow their example, and do not permit intention to surrender. Do you wish to say that I am of different ability from the the ancients?” and getting in close to with a hand towel wipe his face, and Jùn rose and fell to the ground to bow and apologize. When he was appointed Internal Manager, all of Jīngzhōu’s military affairs were consulted on with him. Wǔlíng division Advisor Fán Zhòu persuaded and led the various minorities, plotting to hand over Wǔlíng to join Liú Bèi, and an outer official asked to send a commander commanding ten thousand men to go suppress him. [Sūn] Quán did not listen, instead specially summoned and asked Jùn, and Jùn answered: “Sending five thousand troops would be enough to take [Fán] Zhòu.” [Sūn] Quán said: “Why do you think light of him?”Jùn said: “[Fán] Zhòu is from an old family of Nányáng, rather able to run his mouth, but in fact has no talent for debate. I your Servant can understand him, as [Fán] Zhòu in the past once for his fellow province people prepared a feast, but by noon, the food was still not there, and over ten people got up and left. This is one event from which even a petty man can understand him.” [Sūn] Quán greatly laughed and accepted his advice, and then sent Jùn to lead five thousand, and indeed they beheaded and pacified them.
He was promoted to General Exerting Authority, with fief as Marquis of Chángqiān precinct. (2)
- (2) Wúshū states: Ruì Xuán died, and Jùn absorbed and lead [Ruì] Xuán’s troops, garrisoning Xiàkǒu. [Ruì] Xuán appellation Wénbiǎo was a man of Dānyáng. His father [Ruì] Zhī styled Xuānsì followed Sūn Jiān on campaign and had achievement, and [Sūn] Jiān recommended [Ruì] Zhǐ as Administrator of Jiǔjiāng, later transferred to Wú-jùn, and wherever he was he had reputation. [Ruì] Xuán’s elder brother [Ruì] Liáng styled Wénluán, followed Sūn Cè in pacifying the Jiāng’s east, [Sūn] Cè appointed him Commandant of Kuàjī East Division, he died, and [Ruì] Xuán commanded [Ruì] Liáng’s troops, was appointed Exerting Martial Ability Internal Gentleman-General, and for his achievements was given fief as Marquis of Lìyáng. When [Sūn] Quán was for his son [Sūn] Dēng choosing consorts, the various ministers all praised [Ruì] Xuán, his father [Ruì] Zhǐ, and his elder brother [Ruì] Liáng for all having virtue and righteousness, civil and military ability, all with reputation for three generations, and therefore [Ruì] Xuán’s daughter was chosen as consort. Huángwǔ fifth year  he died, and [Sūn] Quán deeply pitied and begrudged losing him.
[229, Sūn] Quán took Imperial Title. He was appointed as Minister Treasurer, and advanced in fief to Marquis of Liúyáng. (3) He was promoted to Minister of Ceremonies.
- (3) Jiāngbiǎozhuàn states: [Sūn] Quán repeatedly went shooting pheasants, Jùn remonstrated [Sūn] Quán, and [Sūn] Quán said: “After we separate, sometimes I will temporarily go out, and no longer as frequently as before.” Jùn said: “The realm Under Heaven is not yet settled, with countless problems and many affairs. Shooting pheasants is not urgent, but the snapping of bowstrings and breaking of arrows are all capable of doing harm, so I ask that you specially consider your servant’s intentions and set it aside.” Jùn went out, saw a pheasant feather made screen still there, and therefore with his own hand tore and destroyed it. [Sūn] Quán because of this himself stopped, and no longer shot pheasants.
The Wǔxī minority peoples rebelled and joined together, [Sūn] Quán gave Jùn Staff of Authority, to command the various armies to suppress them. His promised rewards were always given, his regulations could not be violated, and the beheaded and captured alive were altogether several tens of thousands, and from then the various minorities were weak, and the whole region was tranquil. (4)
- (4) Wúshū states: General of Elite Cavalry Bù Zhì garrisoned Ōukǒu, and asked to summon and recruit from the various prefectures to increase his troops. [Sūn] Quán asked about this to Jùn, and Jùn said: “A powerful General among the people gradually causes chaos and harm, and moreover [Bù] Zhì has fame and power, wherever he is there are flatterers. You cannot agree.” [Sūn] Quán followed this. Internal Gentleman-General Xú Zōng of Yùzhāng was a famous scholar, once went to the capital, with Kǒng Róng associated, but in conduct was of bad integrity, with his retainers he was overly lenient, did not control them, for his followers built a Palace, and Jùn therefore beheaded him. His adherence to law without fear or private consideration, was all of this sort. Yǐn Fán who submitted [to Wú] for his oral debating was by towering figures befriended, and Jùn’s son [Pān] Zhù also became involved with him, gifting him provisions. Jùn heard this and was greatly furious, writing letter to condemn [Pān] Zhù: “I received the state’s favor and kindness, intending to repay this with my life. You in the capital, used to revere respect and obedience, holding close the worthy and admiring the good; why would you associated with a surrendered prisoner, and give him provisions? When I from afar heard this, my heart shook and my face boiled, and I was depressed for several tens of days. When this letter arrives, immediately go to receive one hundred lashes by cane, to take responsibility for the provisions.” At the time people were all bewildered by Jùn, but [Yǐn] Fán indeed plotted rebellion and was executed, and everyone therefore returned to admiration.
- Jiāngbiǎozhuàn states: At the time Jùn’s aunt’s elder brother Jiǎng Wǎn of Línglíng was Shǔ’s General-in-Chief, and someone reported Jùn to Administrator of Wǔlíng Wéi Jīng, saying that Jùn had secretly sent envoys to communicate with [Jiǎng] Wǎn, wishing to himself plan to stop him. [Wéi] Jīng informed [Sūn] Quán. [Sūn] Quán said: “Chéngmíng would not do this,” at once sending [Wéi] Jīng’s memorial to show to Jùn, and also summoning [Wéi] Jīng back and dismissing him from office.
Before this, Jùn and Lù Xùn both stationed at Wǔchāng, together managed matters there, and later he returned and it was as before. At the time Officer-Manager Lǚ Yī seized and usurped authority, memorializing against Chancellor Gù Yōng and General of the Left Zhū Jù and others, and all met with proscription. Yellow Gate Attendant-Gentleman Xiè Hóng after this asked [Lǚ] Yī: “What will come of this matter?” [Lǚ] Yī answered: “It cannot be good.” [Xiè] Hóng also asked: “If this excellency [Gù Yōng] is dismissed, who will replace him?” [Lǚ] Yī had not yet answered [Xiè] Hóng, when [Xiè] Hóng said: “What if it is Minister of Ceremonies Pān [Jùn]?” [Lǚ] Yī after a long time said: “Your words are accurate.” [Xiè] Hóng said: “Minister of Ceremonies Pān [Jùn] often gnashes his teeth in anger at you, but only because he was far away did he not act against you. Now if he succeeds Excellency Gù [Yōng], one fears that tomorrow he will then strike at you.” [Lǚ] Yī was greatly afraid, and therefore abandoned the [Gù] Yōng affair. Jùn asked to go to Court, visiting Jiànyè, wishing to exhaust himself in remonstrance. When he arrived, he heard the Heir-Apparent [Sūn] Dēng had already repeatedly spoke of this but not been listened to, and Jùn therefore greatly invited the various ministers, wishing to at the meeting personally with blade kill [Lǚ] Yī, sacrificing himself to stop him, to for the state remove a danger. [Lǚ] Yī secretly heard and knew this, and claimed illness and did not go. Every time Jùn advanced to meet [the Emperor], he did not fail to explain [Lǚ] Yī’s treason and danger. Because of this [Lǚ] Yī’s favor gradually decreased, and later was therefore executed. [Sūn] Quán took the blame onto himself, and therefore apologized to the great ministers. This is told in [Sūn] Quán’s Biography [SGZ 47].
Chìsū second year , Jùn died, his son Zhù succeeded. Jùn’s daughter was wed to Marquis of Jiànchāng Sūn Lǜ. (1)
- Wúshū states: [Pān] Zhù appellation Wénlóng, was appointed Cavalry Commandat, later succeeded command of troops, and died young. Zhù’s younger brother Mì, was wed to [Sūn] Quán’s elder sister’s daughter Lady Chén, and transferred to Magistrate of Xiāngxiāng.
- Xiāngyángjì states: Xí Wēn of Xiāngyáng became Chief Pacifier of Jīngzhōu. The Chief Pacifier office is now the Provincial Commander office. [Pān] Mì took leave of [Xí] Wēn, and asked: “My late father in the past said you sir would become the province’s chief consultant. Now it is indeed as he said. In this province is there anyone who can compare to and succeed you?” [Xí] Wēn said: “There is no one better than you.” Later [Pān] Mì became Secretariat Deputy-Director, succeeded [Xí] Wēn as Chief Pacifier, and was deeply praised by the province.
