张胜 / Zhang Sheng (Su Wu mission)

Overview

张胜 / Zhang Sheng (Su Wu mission) is the deputy envoy whose unauthorized involvement in 虞常’s anti-卫律 plot compromises 苏武’s mission to 匈奴. This canonical key distinguishes him from 张胜 / Zhang Sheng (Lu Wan envoy) and 张盛 / Zhang Sheng (late Han).

Current Profile

Hanji 376-1 presents Zhang Sheng as a deputy whose private action crosses the boundary of the formal peace mission. He knows Yu Chang from Han, agrees to reward an attack on Wei Lü, and supplies valuables without Su Wu’s knowledge. When the plot collapses, he delays disclosure until fear of exposure makes concealment impossible.

His later conduct provides the episode’s direct contrast with Su Wu. Zhang helps 常惠 stop Su Wu’s first suicide attempt, but under Wei Lü’s threat of execution he kneels and surrenders. The profile is therefore not simply “cowardly deputy”: Zhang first creates collective liability through unauthorized intervention, then chooses submission when that liability becomes personal.

Key Characteristics

• Deputy envoy under Su Wu in the 100 BCE mission to Xiongnu.
• Secretly accepts Yu Chang’s proposal to kill Wei Lü and gives him valuables.
• Withholds the plot from Su Wu until the failed action is already under investigation.
• Helps Chang Hui prevent Su Wu’s first suicide attempt.
• Is implicated by Yu Chang and surrenders when Wei Lü threatens execution.
• Serves as the episode’s contrast between mission-compromising improvisation and Su Wu’s refusal to yield.

Evidence

• Unauthorized support: Hanji 376-1 says Zhang Sheng agrees to Yu Chang’s plan against Wei Lü and supplies valuables.
• Delayed disclosure: Hanji 376-1 says Zhang tells Su Wu only after Yu Chang is captured and exposure becomes likely.
• Rescue and surrender: Hanji 376-1 says Zhang and Chang Hui stop Su Wu’s first suicide attempt, but Zhang later kneels in surrender when threatened with death.

Qualifications

This profile is bounded to one compact podcast source and does not reconstruct Zhang Sheng’s full biography, later life, private motives, or exact legal status. It treats the source’s moral contrast as an episode-level interpretation and does not infer that this Zhang Sheng is the earlier Lu Wan envoy who shares his name.
