严尤 / Yan You (Xin general)

Overview

严尤 / Yan You enters the wiki through Hanji 664 as the Xin-side adviser whose correct warnings at 昆阳之战 are repeatedly ignored by 王邑. His role is narrow but important: he sees both the strategic target problem and the morale problem created by a fully closed siege.

Current Profile

Yan You first advises Wang Yi to bypass Kunyang and move quickly toward Wan because 刘玄 is there. In the episode’s framing, this would have attacked the political center of the Gengshi field rather than spending time on a smaller city.

When Wang Yi chooses siege instead, Yan You gives a second warning. A besieged force without any exit will not surrender easily; leaving a passage can redirect enemy incentives toward flight and survival. Wang Yi again refuses, so Yan You becomes the defeated side’s internal evidence that the disaster was not caused by ignorance alone.

Key Characteristics

• Xin-side strategist at Kunyang whose advice identifies the enemy’s political center at Wan.
• Warns against letting reputation concerns override operational priority.
• Applies the “围师必阙” logic that a siege should leave an escape path.
• Functions as the ignored-adviser contrast to Wang Yi’s command rigidity.
• Survives the rout, making him a witness to a failed advice chain rather than a battle winner.

Evidence

• Wan-first recommendation: Hanji 664 says Yan You advises Wang Yi to move quickly toward Wan because Liu Xuan is there.
• Strategic diagnosis: Hanji 664 presents Kunyang as less important than the Gengshi center at Wan.
• Siege-exit warning: Hanji 664 says Yan You warns that a closed siege forces defenders toward death-fighting.
• Ignored advice: Hanji 664 says Wang Yi refuses both recommendations.
• Escape after collapse: Hanji 664 says Yan You escapes with Wang Yi and Chen Mao after the army collapses.

Qualifications

The current evidence does not prove that Yan You had a complete winning strategy, only that the episode preserves two warnings that fit later defeat conditions. His broader Xin career, exact office, relationship to Wang Mang, and post-Kunyang fate remain outside this bounded source.

What Changed

• Created this source-scoped adviser page from Hanji 664 to capture the rejected strategic warnings inside the Kunyang defeat.

Relationships

• 王邑 - commander who rejects Yan You’s advice.
• 昆阳之战 - battle where Yan You’s warnings become retrospectively important.
• 更始帝刘玄 - ruler at Wan whom Yan You identifies as the more important target.
• 刘秀 - opposing commander whose counterattack benefits from the failed Xin choices.
• 围困开口式风险权衡 - concept directly illustrated by Yan You’s siege-exit warning.
