Old Well Salt Mine In Nuodeng, China. Editorial Image

Nuodeng village, located in Dali Bai Ethnic Group autonomous prefecture, was once a commercial center along the Ancient Tea Horse Road in western Yunnan province due to its salt industry. However, with the development of sea salt, the well salt of Nuodeng gradually faded out due to its high cost and complex production process. The prosperity of Nuodeng has gone, but the village still retains its traditional craftsmanship and uses it for making hams and pickles, or even artworks.
