Pan Jun (died 239), courtesy name Chengming, was a minister and military general of the state of Eastern Wu during the Three Kingdoms period of China.
During this time, Pan Jun joined the general Lü Dai in suppressing a rebellion by indigenous tribes in his native Wuling Commandery (around present-day Changde, Hunan).
[2][1] Pan Jun was born in Hanshou County (漢壽縣), Wuling Commandery (武陵郡), which is located northeast of present-day Changde, Hunan,[3] towards the end of the Eastern Han dynasty.
[6] At the time, the Chief of Shaxian County (沙羨縣; around present-day Wuchang District, Wuhan, Hubei), which was under Jiangxia Commandery, was notorious for his corruption.
After failing to take Fancheng, Guan Yu returned to Jing Province only to find out that Lü Meng had conquered his key bases in Gong'an County and Nan Commandery (南郡; around present-day Jingzhou, Hubei).
While attempting to retreat to Yi Province to join Liu Bei, Guan Yu was captured in an ambush and executed by Sun Quan's forces.
As Pan Jun lay face down, crying and sobbing in a disconsolate manner,[13] Sun Quan comforted him and told him: "Chengming, in the past, Guan Dingfu was a captive from Ruo, yet King Wu appointed him as a military commander; Peng Zhongshuang was a captive from Shen, yet King Wen appointed him as prime minister.
[15] Some time later, Sun Quan commissioned Pan Jun as General of the Household Who Assists the Army (輔軍中郎將) and put him in command of troops.
I know this because Fan Zhou once said that he would prepare a day-long feast for the folks in the commandery, but the food never showed up by midday so about ten people got up and left.
[20] As a reward for his success, Pan Jun was promoted to General of Vehement Might (奮威將軍) and enfeoffed as the Marquis of Changqian Village (常遷亭侯).
[21] When Rui Xuan (芮玄) died, Pan Jun took over command of his troops and moved to the garrison at Xiakou (夏口; in present-day Wuhan, Hubei).
Around March or April 231, the indigenous tribes living in Wuxi (五谿; literally "five streams"; referring to an area around present-day Huaihua, Hunan) rebelled against Wu rule, Sun Quan granted Pan Jun acting imperial authority and ordered him to supervise the general Lü Dai as he led 50,000 troops to pacify the rebellion.
[27] Sometime the 230s, Sun Quan appointed Lü Yi as the supervisor of the bureau in charge of auditing and reviewing the work of all officials throughout Wu.
[28] Lü Yi freely abused his powers by falsely accusing many officials of serious offences, resulting in some of them being wrongfully arrested, imprisoned and tortured.
[29] Lü Yi initially wanted to make a case against Gu Yong for incompetence and ask Sun Quan to remove him from office.
He pretended to host a banquet, invited all his colleagues to attend, and hoped to use the opportunity to assassinate Lü Yi, whom he regarded as a threat to the Eastern Wu state.
Over time, Lü Yi fell out of Sun Quan's trust and favour, and his abuses of power eventually came to light in 238.
After the Lü Yi scandal was over, Sun Quan sent an apology to all his senior officials for not heeding their advice and urging them to point out his mistakes.
Pan Mi later rose to the position of Supervisor of the Masters of Writing (尚書僕射) and eventually succeeded Xi Wen as the Grand Rectifier of Jing Province.
When Sun Quan sought Pan Jun's opinion on this issue, the latter said: "When overbearing generals are given access to the common people, they will cause harm and chaos to them.
[41] There was one Xu Zong (徐宗) from Yuzhang Commandery (豫章郡; around present-day Nanchang, Jiangxi) who served as a general under Sun Quan.
When a young man like you comes to the Imperial Capital, you should behave in a respectful and humble manner, and seek to build ties with people who are known for their virtues and wisdom.
[45] An uncle of Pan Jun married a sister of Jiang Wan, a senior official of Wu's ally state Shu.
In March or April 231,[25] Wei Jing (衞旌), the Wu-appointed Administrator of Wuling Commandery (武陵郡; around present-day Changde, Hunan), reported to Sun Quan that Pan Jun had been secretly making contact with Jiang Wan with the intention of defecting to Shu.
