皮山国 / Pishan Kingdom (Western Han)

Overview

皮山国 / Pishan Kingdom enters the wiki through Hanji 517 as the Western Regions polity chosen as the endpoint of a limited Han escort for a mission returning toward 罽宾.

Current Profile

The source defines Pishan by its decision-boundary role rather than by a full political history. 杜钦 says the route south beyond Pishan crosses several polities outside Han control and exposes escorts to robbery, provisioning failure, illness, narrow mountain paths, and fatal falls. Stopping at Pishan therefore preserves some diplomatic ceremony while refusing to make Han responsible for the most dangerous and least controllable segment.

Key Characteristics

• Western Regions polity used as a practical escort endpoint.
• Boundary between a limited Han commitment and a route described as beyond reliable Han control.
• Geographic device in a compromise between diplomatic reception and operational risk.

Evidence

• Escort endpoint: Hanji 517 says Du Qin recommends escorting the Jibin mission only to Pishan and then returning.
• Risk boundary: Hanji 517 places multiple uncontrolled polities and severe supply, security, health, and terrain hazards south of Pishan.

Qualifications

This page is bounded to one short podcast summary. It does not reconstruct Pishan’s rulers, precise location, political relationship with Han, full route network, or the original historical text. The route sequence and hazard descriptions remain source-scoped.

What Changed

• Created a bounded polity profile for Pishan’s role as the endpoint of the limited Jibin escort.

Relationships

• 罽宾 - destination beyond the dangerous route for which Pishan becomes the escort cutoff.
• 杜钦 - adviser who selects Pishan as the capacity-matched boundary.
• 外交成本风险核算 - decision framework that makes the endpoint strategically meaningful.
• 能力约束下的边疆承诺 - Pishan marks where ceremony is kept within practical reach.
