When the Tide Left Salt in Stone
Yangpu’s salt pans turn a shoreline material and the sun into a repeated craft of filling, waiting and scraping.
Yangpu Ancient Salt Flats
Volcanic-stone pans turn seawater and sun into salt along Danzhou’s western coast.
The Hainan provincial government describes the Yangpu salt flats as a working heritage site in Danzhou, where seawater enters shallow volcanic-stone pans at high tide and dries under the sun. The account dates the technique to more than 1,200 years ago and says it remains in use. The process begins with stone shaped into a rimmed surface, then seawater gathered at high tide and salt left by evaporation.
