王景 / Wang Jing (Bianqu engineer, Eastern Han)

Overview

王景 / Wang Jing enters the wiki through Hanji 739 as the Eastern Han hydraulic official who, with Wang Wu, leads the large Bianqu works separating Yellow River and Bian River flows under 汉明帝.

Current Profile

The source presents Wang Jing as a technical executor inside a larger state-capacity moment. Earlier repair had been deferred because postwar society could not bear new corvee, but by 69-70 CE the Yongping court has enough peace, grain, and fiscal resources to mobilize large labor and spending.

Wang Jing’s project runs from Xingyang toward the Qiancheng sea outlet and uses long-distance embankment and sluice work to stop the Bianqu overflow. The episode emphasizes both success and cost: the engineering separates the rivers and reduces chronic flooding, while still consuming very large public funds.

The page is deliberately disambiguated because the wiki already has 王敬 / Wang Jing for a later Western Regions official with a different Chinese name.

Key Characteristics

• Eastern Han hydraulic official associated with Mingdi’s Bianqu and Yellow River separation project.
• Technical executor whose work converts a long-unrepaired flood problem into public infrastructure.
• State-capacity marker because the project depends on labor, fiscal surplus, peace, and official appointment.
• Cost-aware engineering figure: the source praises savings but still records very large expense.
• Disambiguated from the later Western Regions 王敬.

Evidence

• Appointment to works: Hanji 739 says Mingdi sends Wang Jing and Wang Wu to build Bianqu embankments after receiving recommendations.
• Deferred repair context: Hanji 739 says Guangwu had considered repair earlier but avoided burdening people who had just suffered war.
• Engineering scope: Hanji 739 describes more than one thousand li of work from Xingyang to the Qiancheng sea outlet with sluices placed at intervals.
• Result and cost: Hanji 739 says the project separates Yellow River and Bian River flows and costs in the tens of billions of cash despite Wang Jing’s saving measures.

Qualifications

The source does not provide a complete engineering report, Wang Jing’s full career, or Wang Wu’s separate role. It also does not prove that the project eliminated all later Yellow River risk. The durable claim is narrower: Wang Jing becomes a named example of successful, expensive, state-backed hydraulic repair during a prosperous early Eastern Han moment.

What Changed

• Created this disambiguated page for 王景, separate from 王敬, to anchor the Bianqu hydraulic works in Hanji 739.

Relationships

• 汉明帝 - ruler whose prosperous Yongping state mobilizes the project.
• 汴渠水利治理 - concept created from Wang Jing’s public-works case.
• Infrastructure Labor Burden - related constraint because the project depends on when society can bear large mobilization.
• 不可行公共工程叫停 - contrast case where canceling a canal project preserves capacity when expected burden exceeds benefit.
• 王敬 - disambiguation target with the same romanized name but different Chinese character and historical role.
