Fields are generally referred to as fields where crops are grown. On the hillsides, a landscape has been formed by a strip of terraces or a wavy section built along the contour line, which is called terrace. Most of them are terraced fields in guangxi and yunnan, where there is more rain and mountains. Terraced fields are built on mountains, among which ailao mountain in yunnan and longshenglong ridge in guangxi are famous. You may not know, located on the west and east sides of the lancang river, a thousand years of salt fields between the mountains. These salt fields have been built with the diligence and sweat of several generations. They not only show the most ancient and original way of sun-dried salt, but also the most special landscape of salt fields in China.

The ancient salt fields, also known as salt Wells, on both sides of the lancang river, are located in yanjing town, mangkang county, qamdo, xizang province. “Salt well” is named for producing salt. Here you can watch the whole process of making salt by hand. You can also see the unique and primitive production tools, hardworking and simple salt people and simple folk customs.

There is something unique about the salt produced in yantian. A river produces different colors of salt at different prices and, of course, different nutrients. There are two kinds of red salt and white salt in salt field. On the Banks of lancang river, some of the soil is red and some is white. Among them, red salt is called red salt, commonly known as peach blossom salt, because most of the peak salt harvest is in the open season of peach blossom, and the color of the salt after drying and sunning is like peach blossom. In addition to the color, red and white salts have different amounts of iron, which is higher in red than white.

Salt making is one of the main sources of income of local people. The first step of salt production is to go down the ladder to the bottom of the cave several meters to ten meters deep, and pour the brine on the back into the salt field. After intense sunlight, the water gradually evaporates. After that, the salt is dried and transported to the market for commodity trading. Salt is sold widely, not only to xizang, but also to sichuan, yunnan and other places.

Thousands of salt fields built on the Banks of the lancang river are supported by a lot of thick wood. In 2009, the thousand-year old yantian was listed as a cultural relic protection site in Tibet autonomous region, and the mankang well salt drying process in Tibet was included in the second batch of the national intangible cultural heritage list. In fact, whether terraced fields or salt fields, these all reflect the imagination and creativity of human beings in the face of the natural environment, which is a model of harmonious coexistence between human and nature.
