于除 / 俞厨 / Yu Chu (Northern Xiongnu)

Overview

于除 / 俞厨 / Yu Chu enters the wiki as the Northern Xiongnu claimant whom Dou Xian sponsored for Han recognition and later as the remnant leader whose arrangement collapsed after Dou’s dismissal. Hanji 765 uses 于除 for the claimant who asks to submit; Hanji 767 uses 俞厨 for the leader destroyed after the failed Dou-backed settlement. The wiki keeps the stable Yu Chu route and records both spellings.

Current Profile

Hanji 765 defines Yu Chu’s entry point. After the Northern Xiongnu chanyu disappears, Yu Chu is identified as the chanyu’s younger brother and right Guli king. He declares himself chanyu near Puli Sea, leads several thousand people, and sends an envoy requesting submission to Han. Dou Xian proposes that Emperor He recognize him as Northern Xiongnu chanyu and supervise him through a Han zhonglangjiang.

The same source also makes Yu Chu a policy test. Yuan An and Ren Kui argue against recognizing him because it would breach the older Southern Xiongnu commitment, risk angering Wuhuan and Xianbei because of their earlier killing of Youliu chanyu, and impose large frontier costs. Emperor He still accepts Dou’s proposal, and the source later treats Yu Chu’s rebellion as confirmation that the objections mattered.

Hanji 767 gives the failed-settlement sequel. While Dou Xian remains powerful, Yu Chu is positioned as leader of a Northern Xiongnu remnant and is supposed to return north under escort. Dou’s fall changes the incentive structure: Yu Chu abandons the agreement and returns north on his own. Emperor He orders Wang Fu, described as jiangbing changshi, to lead more than one thousand cavalry with zhonglangjiang Ren Shang. Yu Chu is killed soon afterward, and his force is destroyed.

Key Characteristics

• Northern Xiongnu claimant who asks Han to recognize him after the chanyu disappears.
• Dependent on Dou Xian’s patronage-backed recognition plan, which ministers criticize as bad frontier policy.
• Figure whose recognition request exposes Southern Xiongnu credibility, Wuhuan-Xianbei resentment, and fiscal-cost objections.
• Later defects by abandoning the agreed return route and moving north independently.
• Destroyed by Han cavalry under Wang Fu and Ren Shang after Emperor He’s order.
• Source-bounded figure who marks post-Dou frontier credibility rather than a full biography.

Evidence

• Identity and request: Hanji 765 says Yu Chu, younger brother of the disappeared Northern Xiongnu chanyu and right Guli king, declares himself chanyu and asks to submit to Han.
• Recognition plan: Hanji 765 says Dou Xian proposes recognizing Yu Chu and supervising him through a Han officer.
• Ministerial objection: Hanji 765 says Yuan An and Ren Kui oppose recognition on Southern Xiongnu credibility, Wuhuan-Xianbei, and fiscal grounds.
• Installation: Hanji 767 says Dou Xian had installed Yu Chu over Northern Xiongnu remnant forces.
• Agreement breakdown: Hanji 767 says Yu Chu abandoned the arrangement after hearing that Dou had been dismissed.
• Imperial order: Hanji 767 says Emperor He sent Wang Fu and Ren Shang with cavalry after Yu Chu’s defection.
• Destruction: Hanji 767 says Yu Chu was killed and his force destroyed.

Qualifications

Yu Chu remains source-bounded to Hanji 765 and Hanji 767. The source spellings differ: Hanji 765 uses 于除, while Hanji 767 uses 俞厨. This page treats them as the same stable Yu Chu route because the two notes describe the same Dou-backed Northern Xiongnu claimant and failed arrangement. Wang Fu’s broader career, Puli Sea geography, the exact return agreement, and Yu Chu’s independent support base are not yet established in the wiki.

What Changed

• Added Hanji 765 as the origin layer for Yu Chu’s recognition request.
• Updated the title and qualifications to preserve both 于除 and 俞厨 spellings under the stable route.
• Reframed Yu Chu as a claimant whose recognition request creates a frontier-credibility dispute before his later defection.
• Preserved Hanji 767’s collapse of the Dou-backed arrangement and Emperor He’s cavalry response.
