TIANJIN -- Archaeologists have recently unearthed the ruins of a salt-making workshop dating back to the Tang Dynasty (618-907) as well as a large number of relics in Dongli District of n\North China's Tianjin municipality, the municipal cultural heritage protection center said Wednesday.
The salt-making workshop is located in the Junliangcheng site, where a large-scale rammed earth platform has also been discovered.
The excavation of the site was launched in April 2021, and an area of 8,000 square meters has been excavated so far.

Household utensils such as pottery jars, pots and bowls, building parts including tiles and bricks, as well as copper coins and animal bones have also been found at the site.
