杨恽 / Yang Yun

Overview

杨恽 / Yang Yun enters the wiki through Hanji 457 as 司马迁’s grandson, a figure associated with the transmission of 《史记》, and a Western Han official whose fall becomes a major qualification to 汉宣帝’s otherwise strong political reputation. Hanji 453 now backfills the earlier 戴长乐 affair: before the later execution, Yang is already removed from office because his reputation for sharp exposure makes him the default suspect when Dai is reported and then counter-reports him.

Current Profile

The current source set presents Yang Yun as a man with real gifts, real faults, and poor danger sense. Hanji 453 gives the pre-disgrace profile: Yang is clean in office, direct before the ruler, and bold enough to have reported rebellion by Huo Guang’s son, but he also boasts of his ability, speaks cuttingly, and likes to expose others’ hidden faults. That everyday pattern creates accumulated enmity default suspicion: when Dai Changle is accused by someone unknown, Yang’s reputation makes him the obvious imagined culprit.

After the Dai Changle affair strips him of title and office, Hanji 457 says he still does not live like a frightened disgraced minister. He keeps wealth, hosts guests, drinks, speaks resentfully, and replies to 孙会宗 with a mocking letter that the source treats as politically explosive once it reaches the court.

His death is therefore not reduced to one cause. The host emphasizes Yang Yun’s failure to read the political room: he has Shiji in the family line but does not learn the caution embodied by his father Yang Chang or by Huo Guang. At the same time, the episode follows 司马光 in treating the punishment as excessive; Yang Yun may be rash and resentful, but the source does not treat his conduct as naturally deserving public waist-cutting and family banishment.

Key Characteristics

• Sima Qian’s grandson and a source-linked transmitter of Shiji into broader circulation.
• Clean and direct official whose courage coexists with boastfulness, sharpness, and a habit of exposing hidden faults.
• Default suspect in the Dai Changle affair because many people already resent or fear him.
• Disgraced former official who keeps social visibility instead of performing withdrawal, fear, and repentance.
• Resentful speaker whose banquet talk and reply to Sun Huizong make private discontent politically usable.
• Victim of harsh Xuan-era punishment, with wife, sons, kin, and associates also affected.

Evidence

Family and historiographical standing:

• Hanji 457 introduces Yang Yun through Sima Qian’s plan to preserve and transmit Shiji.
• Hanji 457 says Shiji’s broader circulation is connected to Yang Yun’s later public life.

Official strengths and relationship risk:

• Hanji 453 says Yang Yun is clean, direct, and willing to speak frankly before the ruler.
• Hanji 453 says Yang Yun boasts of his ability, is sharp and harmful in temperament, likes exposing hidden faults, and therefore has many resentments against him at court.
• Hanji 453 says Dai Changle quickly suspects Yang after being reported, even though the original accuser is unknown.

Disgrace, resentment, and letter evidence:

• Hanji 453 says Dai Changle reports Yang for defending Han Yanshou and for ominous political speech, after which Yang and Dai are both removed from office and reduced to commoners.
• Hanji 457 says Yang Yun loses title and office after the Dai Changle affair but remains materially comfortable.
• Hanji 457 says he holds banquets, gathers guests, and speaks resentfully after drinking.
• Hanji 457 says he answers Sun Huizong’s warning with a mocking reply that later becomes evidence before Xuan.

Punishment and interpretation:

• Hanji 457 says Yang Yun is publicly waist-cut in Chang’an in 54 BCE.
• Hanji 457 says his wife and sons are exiled to Jiuquan, Yang Tan is demoted, and close associates including Wei Xuancheng and Sun Huizong are removed.
• Hanji 457 quotes Sima Guang’s broader criticism that the killings of Zhao Guanghan, Gai Kuangrao, Han Yanshou, and Yang Yun did not convince public opinion.

Qualifications

This page is source-scoped to Hanji 457 and Hanji 453. It does not reconstruct Yang Yun’s full official service, the original legal record, Dai Changle’s full biography, the identity of the person who first accused Dai, or the complete text of Bao Sun Huizong Shu. Hanji 453’s claim that Yu Dingguo may have intentionally leaned hard on Yang is preserved as the host’s inference, not a settled motive. The sources’ criticism of Yang Yun’s political judgment is preserved alongside, not substituted for, Sima Guang’s criticism of Emperor Xuan’s severity.

What Changed

• Added Hanji 453’s earlier Dai Changle affair, making Yang’s first disgrace a result of both accusation politics and his accumulated relationship risk.
• Preserved Hanji 457’s later resentful-letter and execution branch as a separate escalation after commoner demotion.
• Kept the synthesis double-sided: Yang’s official courage and cleanliness coexist with sharp enemy-making and Xuan’s later punishment overreach.
