郑吉 / Zheng Ji (Western Han)

Overview

郑吉 / Zheng Ji enters the wiki through Hanji 461 as the Western Han Western Regions protector who responds to the Wusun crisis after 狂王泥靡 survives the failed assassination and later after Wujiutu kills Nimi. The source presents him as a military and diplomatic coordinator: he relieves Chigu City through regional force and later sends 冯嫽 to persuade Wujiutu before full war begins.

Current Profile

The current evidence is narrow but important. Zheng Ji first appears when Xishenshou surrounds Chigu City after the failed assassination against Nimi. The episode says Zheng Ji gathers cavalry from smaller Western Regions states to rescue 解忧公主 and the Han envoys. Xishenshou retreats after seeing the strength of Han-aligned forces.

His second role is more strategic. When Wujiutu claims the Wusun title and faces Han deployment, Zheng Ji chooses Feng Liao as the intermediary because she understands Han documents and Western Regions affairs, is respected by local states, and is connected by marriage to the Wusun right general. Zheng Ji therefore becomes the official who turns military readiness into a negotiated route before the crisis becomes open war.

Key Characteristics

• Western Han frontier official operating through the Western Regions protectorate field.
• Coordinates regional cavalry to relieve the Chigu City siege after the failed Nimi assassination.
• Treats Wusun as a strategic hinge in Han-Xiongnu competition, not only as a local succession dispute.
• Uses Feng Liao’s personal authority and Wusun network as a diplomatic instrument.
• Combines coercive pressure with intermediary-based negotiation.

Evidence

• Chigu relief: Hanji 461 says Zheng Ji gathers cavalry from Western Regions states to rescue Xieyou and the Han envoys when Chigu City is surrounded.
• Deterrent effect: Hanji 461 says Xishenshou flees after seeing that Han forces are numerous.
• Mediation choice: Hanji 461 says Zheng Ji sends Feng Liao to persuade Wujiutu because of her Wusun and Western Regions ties.
• War-pressure context: Hanji 461 says Han and Western Regions forces are already confronting Wujiutu when Feng Liao carries the warning.
