甘忠可 / Gan Zhongke (Western Han)

Overview

甘忠可 / Gan Zhongke enters the wiki through Hanji 581 as a Western Han fangshi-style figure from Qi who uses 《太平经》 and renewed-mandate language to approach 汉成帝 during the emperor’s no-heir anxiety.

Current Profile

The source presents Gan Zhongke as a specialist who turns an actual imperial vulnerability into a cosmic diagnosis. He claims Chengdi’s lack of heirs shows that Liu-family mandate power has declined and that the emperor must receive Heaven’s command anew. 刘向 rejects this as spirit-based deception, Chengdi accepts Liu Xiang’s judgment, and Gan dies in prison after arrest.

Gan’s significance is larger than his failed Chengdi approach because 夏贺良 later preserves the method and reintroduces it under 汉哀帝. The source therefore treats Gan as the origin point of a technique that can survive punishment and become newly persuasive when court disorder, illness, and omen anxiety intensify.

Key Characteristics

• Uses no-heir anxiety as the opening for a heavenly-mandate diagnosis.
• Links 《太平经》 to Liu-family sacred legitimacy rather than to ordinary private cult practice.
• Fails because Chengdi consults Liu Xiang and accepts skeptical counsel.
• Becomes politically important through transmission to Xia Heliang after his own death.

Evidence

• Mandate diagnosis: Hanji 581 says Gan claims Chengdi’s childlessness shows Liu-family mandate decline and requires renewed Heaven authorization.
• Skeptical defeat: Hanji 581 says Liu Xiang identifies the claim as spirit-based deception and Chengdi orders Gan’s arrest.
• Transmission: Hanji 581 says Xia Heliang continues studying Gan’s text after punishment.

Qualifications

This page reflects the episode’s account rather than a full intellectual history of Gan Zhongke or the Taipingjing tradition. His authorship, textual details, follower network, and inner motive remain source-scoped.

What Changed

• Created from Hanji 581 as the Chengdi-era origin point for the renewed-mandate fangshi method later used under Han Aidi.

Relationships

• 《太平经》 - text Gan uses to package mandate renewal and social peace.
• 汉成帝 - ruler Gan tries to persuade through no-heir anxiety.
• 刘向 - skeptical adviser whose judgment defeats Gan’s proposal.
• 夏贺良 - disciple who preserves and later reactivates Gan’s method.
• 再受命改制合法性反噬 - later Aidi pattern made possible by Gan’s original claim.
