耿育 / Geng Yu (Western Han)

Overview

耿育 / Geng Yu is synthesized as a Western Han memorialist whose two current wiki appearances show court writing as political repair. Hanji 570 presents him defending 陈汤 and 甘延寿 against disproportionate disgrace after their 郅支单于 victory, while Hanji 574 presents him defending 汉成帝’s succession choice and giving 汉哀帝 a politically usable reason to stop further investigation of 赵飞燕-linked palace accusations.

Current Profile

The sources present Geng Yu less as a biographical subject than as a political writer. In Hanji 570, he argues from military memory and future morale: if the court used the Zhizhi victory to proclaim Han prestige but then let Chen Tang be reduced, imprisoned, or driven away because of slander and later faults, future capable people would fear offering plans or risking themselves. His advice succeeds at least enough for Aidi to recall Chen Tang to Chang’an to live out his final years.

In Hanji 574, Geng Yu’s method shifts from military merit to succession legitimacy. His memorial first acknowledges ordinary succession norms, then cites the Zhou precedent of Taibo yielding so that Jili and Ji Chang could continue the line. From there, he argues that Chengdi’s choice of Aidi was not scandal or weakness but foresight: a young biological son might have left power with a mother, unstable ministers, or disorderly regency politics.

Geng Yu’s practical achievement is narrative conversion. In one case, he turns a disgraced veteran into evidence that public honor and state credibility are linked; in the other, he turns continued investigation into a reputational danger for Chengdi and an unfilial burden for Aidi, while ending the case becomes clarification of rumor, completion of the deceased ruler’s intention, and protection of dynastic reputation.

Key Characteristics

• Western Han memorialist known in this wiki from Suihe 2 / 7 BCE and Jianping 1 / 6 BCE source layers.
• Defends military merit by warning that degrading Chen Tang after the Zhizhi campaign will chill future service.
• Uses classical precedent to make an unusual succession decision politically and ritually defensible.
• Reframes palace scandal into Chengdi’s long-range statecraft.
• Gives Aidi a public rationale for stopping a case he is already inclined to close.
• Shows how court writing can alter decision conditions by binding merit, memory, filial duty, reputation, and political stability.

Evidence

• Source roles: Hanji 570 and Hanji 574 identify Geng Yu as the author of the memorials discussed in those episodes.
• Chen Tang defense: Hanji 570 says Geng Yu recalls Chen Tang and Gan Yanshou’s distant victory over Zhizhi Chanyu and argues the court should not erase that merit.
• Future-service warning: Hanji 570 says Geng Yu warns that later people may refuse to offer plans or die for Han if extraordinary merit ends in slander and abandonment.
• Practical effect: Hanji 570 says Aidi orders Chen Tang recalled to Chang’an, where Chen Tang later dies.
• Classical precedent: Hanji 574 says he uses the Zhou Taibo-Jili-Ji Chang succession story to justify exceptional action under exceptional circumstances.
• Chengdi defense: Hanji 574 says he presents Chengdi’s choice of Aidi as prevention of child-ruler and maternal-regency danger.
• Case closure: Hanji 574 says Aidi stops pursuing the details of the relevant accusations after reading the memorial.

Qualifications

This page is source-bounded. Hanji 570 and Hanji 574 give Geng Yu’s memorial logic and effects, but not a full career, exact office, broader writings, or complete text-critical history of either memorial. The page therefore treats him as a court-rhetorical actor rather than a fully reconstructed official.

What Changed

• Added Hanji 570’s earlier Chen Tang defense, making Geng Yu’s profile a two-memorial pattern of court narrative repair.
