Heijing: Where salt was king
At first glance Heijing is just a charming little town along a clean but shallow river in the mountainous middle of Chuxiong Prefecture in central Yunnan. Terraced fields step up the slopes on both sides. The blue-grey humps of higher mountains loom to the north. Smooth red sandstone lines the Longchuan River banks and is the main building material in the town.
