Déxìng

In the hills of northeastern Jiangxi, Dexing is a place of mineral wealth. Copper was worked in the Tongchang area in the Tang and Song periods, when the demand for metal made mining an important part of the district's history. After the earlier workings had declined, mining at Tongchang was revived between 1465 and 1488, during the Ming dynasty. The ores of the Dexing district also contain other metals, including gold and silver, making its hills valuable for more than copper alone.
