贾让 / Jia Rang (Western Han)

Overview

贾让 / Jia Rang is recorded in the wiki as the Western Han proposer of the upper, middle, and lower Yellow River control policies discussed in Hanji 567.

Current Profile

Hanji 567 presents Jia Rang as a hydraulic-policy thinker rather than as a biographical subject. His key contribution is a ranked diagnosis of flood control: do not keep tightening embankments around a river whose natural space has already been occupied. The upper policy relocates people out of flood-prone land and lets the Yellow River resume a northern outlet; the middle policy divides water through canals, stone embankments, and sluices; the lower policy repairs old levees but keeps the recurring burden intact.

His reasoning links engineering to political economy. He argues that early settlement avoided river paths, while Warring States levees by Qi, Zhao, and Wei made local self-protection create reciprocal harm. In the episode’s modernizing reading, Jia Rang becomes a model for floodplain retreat governance: solve the land-water structure before endlessly paying for repairs.

Key Characteristics

• Jia Rang ranks water-control policies by whether they address the structure of flood risk rather than by short-term convenience.
• His upper policy accepts one-time relocation and loss to reduce recurring levee repair and catastrophic breach risk.
• His middle policy preserves a more engineered compromise through canals, sluices, and irrigation.
• His lower policy is criticized because repairing old levees consumes labor and money without ending the river-space conflict.
• His argument treats land use, settlement location, fiscal burden, and hydraulic danger as one governance system.

Evidence

• Three policies: Hanji 567 says Jia Rang quickly submits upper, middle, and lower Yellow River policies after the court requests flood-control proposals.
• Settlement principle: Hanji 567 says Jia Rang praises older practice for placing cities and people beyond the reach of river water.
• Levee criticism: Hanji 567 says Warring States states pushed risk back and forth by building levees along both banks.
• Upper policy: Hanji 567 says Jia Rang proposes moving Jizhou floodplain residents, opening the Liyang Zhehai Pavilion embankment, and letting the river flow north into the Bohai Sea.
• Middle policy: Hanji 567 says Jia Rang proposes canals, stone embankments, and gates for irrigation and flood diversion.
• Lower policy: Hanji 567 says Jia Rang treats old-levee repair as an inferior choice that keeps public burden and flood risk recurring.

Qualifications
