虞常 / Yu Chang (Western Han-era)

Overview

虞常 / Yu Chang is a Han-connected participant in the failed Xiongnu-court plot that exposes 张胜 and turns 苏武’s completed diplomatic mission into a detention and surrender crisis.

Current Profile

Hanji 376-1 says Yu Chang approaches Zhang Sheng privately, offers to arrange the killing of 卫律, and asks that his mother and younger brother in Han be rewarded. Zhang agrees and gives him valuables.

The wider plan fails after one participant informs. Yu Chang is captured alive, interrogated, and implicates Zhang Sheng. Wei Lü later has him executed in front of the Han envoys as part of the coercive surrender scene.

Key Characteristics

• Han-connected plot participant operating inside Xiongnu territory.
• Uses his prior acquaintance with Zhang Sheng to seek sponsorship and family rewards.
• Joins a wider plan involving court abduction and the killing of Wei Lü.
• Is captured after the plan is disclosed and the plotters are attacked.
• Implicates Zhang Sheng under investigation and is later executed before the mission.

Evidence

• Proposal and sponsorship: Hanji 376-1 says Yu Chang proposes killing Wei Lü, requests rewards for family in Han, and receives valuables from Zhang Sheng.
• Failure and implication: Hanji 376-1 says the plot is exposed, Yu Chang is captured, and he identifies Zhang Sheng’s involvement.
• Execution: Hanji 376-1 says Wei Lü executes Yu Chang before threatening the Han envoys with death or surrender.

Qualifications

The supplied transcript writes the name as “于常”; this page normalizes it to the received Han Shu form “虞常” while preserving the variant in the source note. The source does not provide a complete biography, settle every participant’s role, or independently verify the dialogue and motive attributed to him.

What Changed

• Created the canonical page and normalized the transcript’s “于常” to 虞常.

Relationships

• 张胜 - prior acquaintance who funds Yu Chang’s proposal and is implicated by him.
• 卫律 - intended target who later investigates and executes him.
• 苏武 - uninvolved chief envoy drawn into the collective diplomatic crisis.
• 匈奴 - political setting in which the plot fails and Yu Chang is captured.
