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.

Current Profile

The episode presents Yang Yun as a man with real historical standing but poor danger sense. After the Dai Changle affair strips him of title and office, he 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.
• 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.
• Negative example of failing to turn historical inheritance into practical survival judgment.
• 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.

Disgrace, resentment, and letter evidence:

• 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. It does not reconstruct the full Dai Changle affair, Yang Yun’s earlier official service, the original legal record, or the complete text of Bao Sun Huizong Shu. The episode’s criticism of Yang Yun’s political judgment is preserved alongside, not substituted for, Sima Guang’s criticism of Emperor Xuan’s severity.

What Changed

• Created the page from Hanji 457’s account of Yang Yun’s fall, punishment, and historiographical framing.
