丁义 / Ding Yi (Western Han)

Overview

丁义 / Ding Yi is presented as the 乐成侯 who brings 栾大 to 汉武帝 through a recommendation chain involving his sister, the widow of 胶东康王刘寄, and is later executed after Luan Da’s supernatural claims and false report collapse.

Current Profile

Hanji 344-1 gives Ding Yi a narrow but more concrete access role. His sister, presented as the childless widow of 胶东康王刘寄 and in conflict with the successor, wants to gain Wudi’s favor after 少翁’s death; Luan Da reaches the emperor through Ding Yi. The source does not clarify whether Ding Yi independently endorses Luan Da’s claims, merely carries the recommendation, or knows how the “斗棋” demonstration works.

Hanji 344-2 supplies the liability endpoint. When Luan Da is executed, Ding Yi is publicly beheaded, showing that a coercive patron can extend responsibility from a failed specialist to the broker who supplied access even when the surviving source note does not establish the broker’s knowledge or intent.

Key Characteristics

• Western Han marquis identified by the title 乐成侯.
• Court intermediary in a family-linked recommendation chain that brings Luan Da to Han Wudi.
• Recommender whose own knowledge and motive are not supplied.
• Subject of derivative accountability after Luan Da’s claims are exposed.

Evidence

• Access chain: Hanji 344-1 places Ding Yi between his sister’s court-favor effort, Luan Da, and Wudi.
• Recommendation: Hanji 344-2 identifies Ding Yi as the recommender who brought Luan Da to imperial attention.
• Punishment: Hanji 344-2 says Ding Yi was publicly beheaded after Luan Da’s execution.

Qualifications

Two adjacent short podcast summaries are the complete current evidence inventory. They do not establish Ding Yi’s full biography, his sister’s identity or strategy independently, the recommendation procedure, his relationship with Luan Da, knowledge of the performance or later fabrication, statutory liability, trial, or exact execution sequence. His punishment demonstrates attributed recommender liability in the episode; it does not prove guilt by modern evidentiary standards.

What Changed

• The profile now records the family-linked access chain behind the recommendation while keeping Ding Yi’s knowledge and motive unresolved.

Relationships

• 栾大 - specialist whom Ding Yi recommends.
• 汉武帝 - ruler who accepts the recommendation and later extends punishment to the recommender.
• 方士问责陷阱 - accountability spreads from the miracle claimant to the broker who supplied court access.
• 方士骗术与权威 - recommendation is one institutional channel through which unverifiable expertise gains authority.
