A 2023 town profile describes Heijing as a former tribute-salt producer on the Longchuan River, with a traditional layout and 21 protected heritage sites. It traces salt extraction from brine springs through later well and boiling systems, and describes the Ming and Qing periods as production’s height.

Heijing and Salt: Wells, Courtyards and the Qing’an Embankment
Heijing’s surviving streets are legible through the salt economy that supported the town and the infrastructure built to protect it.

Wells, households and river works
The Qing’an Embankment links industry and settlement. The local page says it began in the late Ming, was completed in the Daoguang period and still serves flood-control functions. Beside wells, boiling sites and the Wu family courtyard, it shows that salt towns depended on water management and safe routes as well as salt.
The profile also repeats a black-ox origin story for the brine. It is a local legend, not an archaeological account. Distinguishing legend, administrative history and material remains lets Heijing’s salt landscape remain rich without turning tradition into literal proof.
Salt reorganized work and urban form. Brine had to be collected, stored and heated; fuel, water and transport were part of production. The town’s local chronology describes a shift from spring collection to wells and boiling, followed by government oversight and salt taxation. Qing’an Embankment adds another layer: flood protection remains part of the river town’s physical geography, alongside the courtyards and lanes shaped by the salt economy.
The town profile’s examples give this history a route through surviving places. The Wu family compound, wells and salt-boiling sites point to domestic life, extraction and production; Qing’an Embankment carries the story to the river edge. Together they show how salt linked households, labour and public works.
