Zhang Yu / 张瑜 (Western Han)

Overview

Zhang Yu / 张瑜 enters this wiki through Hanji 549 as 汉成帝’s teacher and the named target of 朱云’s public accusation. The episode uses him less as a full biography than as the protected figure whose status makes Zhu Yun’s direct speech explosive.

Current Profile

The current profile is deliberately narrow. Zhang Yu is presented as Chengdi’s teacher and as the person Zhu Yun identifies after being pressed to name the 佞臣 he wants to execute with the imperial sword. Because Zhang Yu is tied to Chengdi personally, Zhu Yun’s accusation touches both court hierarchy and imperial emotion.

The episode does not independently establish Zhang Yu’s broader policy role or guilt. Its narrative function is to show how direct criticism becomes dangerous when it names a figure protected by personal trust, rank, and teacher-student intimacy.

Key Characteristics

• Western Han court figure identified as Han Chengdi’s teacher.
• Protected target whose naming turns Zhu Yun’s moral critique into a palace crisis.
• Embodies the episode’s risk boundary between abstract criticism of bad ministers and direct accusation against a ruler’s intimate authority figure.

Evidence

• Imperial-teacher status: Hanji 549 identifies Zhang Yu as Chengdi’s teacher.
• Named target: Hanji 549 says Zhu Yun names Zhang Yu when Chengdi asks which minister he means.
• Crisis effect: Hanji 549 says Chengdi becomes enraged because Zhu Yun insults ministers and his teacher.

Qualifications

This page preserves the source’s 张瑜 form and does not merge it with other same-pronunciation figures. The episode does not provide a full Zhang Yu biography, so his offices, teachings, and broader historical evaluation remain source-scoped.

What Changed

• Added Zhang Yu as the protected target of Zhu Yun’s Hanji 549 accusation.

Relationships

• 汉成帝 - emperor and student whose anger is triggered by the accusation.
• 朱云 - remonstrant who names Zhang Yu as the official to punish.
• 君臣反馈失灵 - adjacent concept because protected intimacy makes truthful accusation dangerous.
