Tianjin's Changlu Hangu Salt Field marked its 1,100th anniversary on Thursday. The area has undergone a transformation from an ancient saltwork into a model of green and high-quality development.

Founded in 925, the Hangu Salt Field is a key production base along the Bohai coast in eastern China, with an annual output of about one million tons. Over the centuries, it has evolved from the ancient method of "boiling seawater for salt" to intelligent production systems that integrate industrial operations with cultural tourism.

"We are not only preserving a millennium-old salt field, but also protecting a cultural heritage passed down through generations," said Yan Haibin, head of the publicity department at the Hangu Salt Field.
