都江堰 / Dujiangyan

都江堰 / Dujiangyan enters the wiki through 《资治通鉴·周纪》52丨 陈庄叛秦 端起碗吃饭放下碗骂娘 as the later irrigation project the episode uses to explain why conquered 蜀国 becomes so valuable to 秦国. The source attributes the project to 李冰 and his son.

The episode’s use of Dujiangyan is strategic rather than engineering-focused. It marks the shift from hard-to-enter territory to a productive 巴蜀 grain base that can feed Qin’s larger expansion.

Connections

• 李冰 - figure associated with the project in the source.
• 蜀国 and 巴蜀 - regional context.
• 秦国 - state that benefits from the grain base.
• 受任地方长官割据风险 / Appointed Governor Secession Risk - concept because regional productivity increases the temptation of local control.
