李勋 / Li Xun (Western Han flood-control adviser)

Overview

李勋 / Li Xun enters the wiki through Hanji 532 as a Pingling man who advises 汉成帝 during a Yellow River flood. He is distinct from 李寻, the later omen adviser.

Current Profile

Hanji 532 gives Li Xun a narrow hydraulic-policy role. After the Yellow River floods Bohai, Qinghe, and Xindu, court discussion turns toward finding old branch channels and digging them again. Li Xun argues against hasty intervention. His proposal is to let the river’s current breach reveal its flow direction first, then follow the river’s own tendency and shape a channel with dredging and planning.

The source treats the advice as a patience-and-cost argument. Li Xun warns that immediate improvised works would consume time, money, and labor. Chengdi accepts the memorial and stops the repair effort, while still sending envoys to settle and assist flood victims. Li Xun therefore becomes an earlier Western Han counterpart to later river-policy debates: not floodplain retreat in Jia Rang’s fully articulated sense, but observation before forced engineering.

Key Characteristics

• Pingling adviser associated with an 18-17 BCE Yellow River flood under Han Chengdi.
• Opposes rushed attempts to restore old channels before the river’s current behavior is understood.
• Frames river repair as needing to follow water tendency rather than impose an expensive premature design.
• Creates tension between hydraulic patience and immediate disaster suffering.
• Must be disambiguated from 李寻, the omen-politics figure.

Evidence

• Flood context: Hanji 532 says the Yellow River floods Bohai, Qinghe, and Xindu, submerging 31 counties and destroying more than 40,000 official pavilions and houses.
• Policy contrast: Hanji 532 says other ministers discuss finding and reopening old branch channels.
• Observation-first advice: Hanji 532 says Li Xun recommends letting the breach run temporarily, watching the water tendency, then shaping the channel accordingly.
• Cost warning: Hanji 532 says he warns against wasting time, money, and labor through hasty works.
• Imperial response: Hanji 532 says Chengdi accepts the advice and does not block the breach, while sending envoys to assist victims.

Qualifications

This page is bounded to one source note. It does not supply Li Xun’s office, full biography, complete memorial text, hydrological evidence, or later assessment of whether the non-repair decision reduced or worsened harm. The advice should not be flattened into modern environmental policy; the source preserves both the logic of following water and the suffering of disaster victims.

What Changed

• Created this disambiguated page from Hanji 532 to separate the flood-control adviser 李勋 from the omen adviser 李寻.

Relationships

• 黄河 - river whose flood creates Li Xun’s policy occasion.
• 汉成帝 - ruler who accepts Li Xun’s advice.
• Flood Control Risk Transfer - adjacent flood-governance concept because non-repair and channel choice allocate damage across places.
• 贾让 - later Western Han hydraulic thinker whose proposals develop a more explicit flood-control framework.
• 李寻 - similarly romanized but distinct Western Han figure.
