The newly discovered ancient salt boiling site is located in the east of Yangerzhuang Town, Huanghua City, about 2.5 kilometers away from the Haifeng Town site, a national key cultural relic protection unit. The Hebei Provincial Institute of Cultural Relics and the Huanghua Municipal Museum are jointly conducting rescue excavations at the site. Within an area of nearly 1,500 square meters, there are many oval or nearly circular areas of red-burnt earth scattered in the area. The accumulation of plant ash or red earth in them is clearly identifiable. It is speculated that they should be the salt stoves used to cook salt at that time.
At present, many ancient salt cooking stoves have been discovered, some of which have been damaged to varying degrees. Their plane sizes vary greatly, ranging from 1 meter to nearly 6 meters in diameter. In addition, many ash ditches, ash pits and other relics were found around the salt stove.

Archaeologists said that from the pottery shards, porcelain shards, hooked bricks and other artifacts that have been discovered, it can be inferred that the age of the site can be traced back to the Tang Dynasty. The specific age span, number of remains, distribution and functions require further archaeological excavation and research. “Relics such as salt stoves, flues, brine ditches, and salt pits found on site completely outline the production trajectory of the ancient salt-making handicraft workshops. You can imagine the busy production scenes at that time. ”Lei Jianhong, director of the Underwater Archeology Research Office of the Hebei Provincial Institute of Cultural Relics, said, "This discovery fills the gap in the archeology of the salt industry in Hebei Province. It can provide a more intuitive understanding of the scale of ancient salt industry production, the level of salt production technology, the overall situation, etc., and is of great significance to the study of the social and economic development at that time. ”

Huanghua has a coastline of more than 60 kilometers and has been "profitable from fish and salt" since ancient times. According to city records, the history of salt production can be traced back to the Western Zhou Dynasty. For more than two thousand years, the main method of salt production was boiling, that is, "boiling the sea to make salt." In the mid-Ming Dynasty, boiling was gradually replaced by beach-drying, and brine was produced by absorbing tides and crystallized into salt.
