居弥王成国 / King Chengguo of Jumi

Overview

居弥王成国 / King Chengguo of Jumi is the Western Regions ruler in Hanji 838 whose hostility toward Khotan turns Zhao Ping’s death into an accusation against 于阗王建. His profile is defined by information manipulation: he supplies the story that lets 王敬 mistake private rivalry for a chance at Han-backed merit.

Current Profile

Chengguo first intervenes when Zhao Ping’s son passes through 居弥国 with his father’s coffin. Because Chengguo has old enmity with King Jian, he tells the son that Zhao Ping was harmed at Jian’s direction through a Xiongnu doctor. The accusation then travels to Dunhuang and brings Wang Jing into the investigation.

Chengguo reinforces the claim when Wang Jing passes through Jumi. He tells Wang that Khotanese people want Chengguo as king and encourages Wang to use the death of a Han official as a pretext. The banquet killing that follows is carried out directly by Chengguo’s registrar Qin Mu, making Chengguo’s court materially involved even if Wang Jing is the Han official who authorizes the scene.

Key Characteristics

• Local rival of Khotan King Jian whose old grievance shapes the accusation.
• Information broker who converts Zhao Ping’s death into a politically useful murder claim.
• Persuader who tells Wang Jing that Khotan’s population would welcome Chengguo.
• Indirect beneficiary-seeker whose claim points toward replacing Jian with himself.
• Source case for how a dependent frontier ruler can capture Han official action through rumor.

Evidence

• Enmity with Khotan: Hanji 838 says Chengguo and King Jian have old hatred.
• First accusation: Hanji 838 says Chengguo tells Zhao Ping’s son that Jian used a Xiongnu doctor to kill Zhao Ping.
• Persuasion of Wang Jing: Hanji 838 says Chengguo tells Wang that Khotanese people want Chengguo as king.
• Material involvement: Hanji 838 says Chengguo’s registrar Qin Mu beheads King Jian at the banquet.

Qualifications
