呼韩邪单于比 / Huhanye Chanyu Bi

Overview

呼韩邪单于比 / Huhanye Chanyu Bi enters the wiki through Hanji 724 as the 日逐王 who turns an internal Xiongnu succession threat into the founding current layer of 南匈奴. His profile matters because the Southern/Northern split begins with a succession breach, secret Han contact, and a calculation that submission to 光武帝刘秀 is safer than remaining under the northern chanyu’s control.

Current Profile

Hanji 724 says Bi leads the southern eight tribes and becomes exposed after the chanyu Yu kills Zhiya Shi to clear a succession path for his own son. Bi reduces attendance at the royal court, is watched by two Gudu hou, and secretly sends Guo Heng to a Han frontier official with a Xiongnu map. When the Gudu hou urge the chanyu to kill him during the Longcheng ritual, the plan leaks, and Bi’s brother warns him in time.

Bi then gathers the southern eight tribes, reportedly forty to fifty thousand people or troops in the episode’s telling, and the northern chanyu’s ten thousand cavalry withdraw after seeing the larger force. In 48 CE, the eight tribal leaders raise Bi as Huhanye Chanyu. Bi sends envoys to the Wuyuan frontier asking to become a permanent Han vassal and to resist Northern Xiongnu for Han.

Key Characteristics

• Southern Xiongnu founder in the current wiki’s Eastern Han evidence.
• Succession-threat actor whose break begins after Yu kills Zhiya Shi and disrupts expected heir order.
• Frontier defector who uses secret Han contact and a Xiongnu map before public submission.
• Mobilizer of the southern eight tribes after the attempted killing plot leaks.
• Huhanye-title claimant whose submission lets Han court debate buffer strategy rather than immediate conquest.

Evidence

• Succession rupture: Hanji 724 says Yu kills Zhiya Shi so his own son can control the succession path, making Bi distrust the northern royal court.
• Secret Han contact: Hanji 724 says Bi sends Guo Heng to a Han frontier official and offers a Xiongnu map.
• Attempted purge and mobilization: Hanji 724 says the killing plan leaks, Bi’s brother warns him, Bi gathers the southern eight tribes, and the northern chanyu’s force withdraws.
• Submission request: Hanji 724 says the tribal leaders raise Bi as Huhanye Chanyu and he asks Han to accept him as a permanent vassal resisting Northern Xiongnu.

Qualifications

This page is bounded to Hanji 724 and does not reconstruct the full Southern Xiongnu chanyu line. The title 呼韩邪 is used here for Bi’s Eastern Han Southern Xiongnu branch and is not merged with the older Western Han Huhanye chanyu. Force counts, Guo Heng’s identity, the exact succession law, and the two Gudu hou remain source-scoped until later source notes add evidence.

What Changed

• Created a canonical page for Bi as the Eastern Han Huhanye Chanyu and Southern Xiongnu founder.
• Scoped his significance to the 47-48 CE split-origin layer rather than the later protected settlement.
• Disambiguated this Huhanye-title actor from the older Western Han chanyu.

Relationships

• 南匈奴 - polity whose current wiki origin layer begins with Bi’s elevation and submission request.
• 北匈奴 - rival field from which Bi breaks after succession and safety conflict.
• 匈奴 - broader steppe polity split by Bi’s move.
• 光武帝刘秀 - Han ruler whose court accepts Bi’s submission after debate.
• 耿国 - Han adviser who argues that accepting Bi can stabilize the frontier.
• 边郡恢复治理 - policy aim Geng Guo attaches to accepting Bi’s bloc.
• 名声约束下的战争节制 - related decision pattern because Liu Xiu does not immediately turn Bi’s split into an annihilation campaign.
