Markam County is known as a place with rich salt resources since ancient China. Salt fields are mainly built on cliff slopes and riversides of the Lancang River. Local people in Naxi evaporate brine in the sun with an ancestral technique since Tang Dynasty (618-907 AD).

With a large amount of yearly output of salt products, salt-production has become a main income for local people. Furthermore, the salt fields here and local folk customs also become a unique attraction to visitors. (Xinhua/Sun Fei)
