Wang jian: the city salt lake is also known as the city salt pool, which is located in the eastern part of the ancient river area, along with the anma, and is also known as the east river salt pool, the deterrence pool, the anma salt pool, etc. It is also known as a pool because its management was located in the village, and the salt produced is called a salt. In addition to salt, the lake's water is rich in other minerals and chemical elements, especially sodium sulfate (commonly known as dang). The level of sodium sulfate is extremely high and ranks among the world's three largest inland salt lakes。
According to geology studies, the city salt lake was initially formed some 65 million years ago during the himalayan tectonic period, with the north of the central mountain tectonically modified to form a narrow fracture zone, with salt mines concentrated below the surface of the shallows. The lake's water originates mainly from rain and flash floods, and northern song is known as the “four mountain waters” of dream creek, which gathers hundreds of miles of freshwater lakes over the salt layer. In explaining china's traditional concept of “five lines”, sang-hoon hong fan points out that “sweat under water” “sweats”, a simple and vivid illustration of the rationale behind the formation of saline lake water, i. E., the melting of the salt mine into halo following the infiltration of surface fresh water into the ground and subsequent rises to the ground through a catheteric effect, thus transforming the freshwater lake into a saline lake。

After millions of springs and autumns of sun and wind erosion, more than 4,000 years ago, the salt pond finally waited for the ancient people of china to come after salt. They take this position, settle and thrive, and the chinese civilization begins. The three kings of tangyao, yao sun, and hao hao hao, are determined by the peaceful sun near the salt ponds, which are now in the middle of the season, and by the city, which is in the middle of the summer. For hundreds of years, the construction and development of the salt lake of the city has been seen as a major national undertaking, while the song of the south wind has also sung the people's dependence on the salt pond: “the south wind is so dry that we can solve the problem of our people. When it's the south wind, it can wipe out the wealth of our people."
Because of its age and significance, the chinese civilization has given this mother's pool a unique chinese word for it — “single”, which is “old”, “old”, and salt ponds. One word, one of china's thousands of years of civilization. Salt iron is a vital resource in ancient countries, where livelihoods and strategies lie. In order to protect the salt ponds and prevent abusive exploitation, a city of salt transport was born, known as the “portation city” until today。
Looking around the global equivalent of salt lakes, be they the great salt lake in utah, united states, or the kuchuk salt lake in siberia, russia, is far less ancient and unique to the history and civilization of the country. And the famous dead sea of israel, long and rich in resources, is well known for most of the leisure resorts that were subsequently developed or for the ancient scriptures that were found there, and for the description of the exploitation of its own salt mine resources, only the asphalt that it produces can be used in ancient mummies. In contrast, the chinese culture's description of the city's salt lake is “the history of history, the book to date, the book to date, and the scripts to date, and the writings of private individuals”, which have been, from ancient times to the present day, very simple。

China news agency journalist: the city salt lake has a history of mining for over 4600 years. Why is it called “the living fossils of ancient chinese technology”? Why is this salt process 1,000 years before europe
Wang jian, “silving the sun” is a central expression of the production of salt from the water ponds of the city. By definition, “reclamation” refers to the cultivation of fields on the ground, and “sunning” is the introduction of salt lake water into the ground and the drying of raw salt. On the surface, the tanning technique is nothing more than an expansion of the saline-water dispersion area, except the use of salt fields. However, that is not the case。
The raw method of producing the salt is daily exposure, natural crystallization, collective extraction, and exclusive reliance on natural power. Thus, the salt which is tanned contains a large quantity of impurities, in particular magnesium sulfate, which is very large and bitter, and the first salt is therefore called bitter salt, and the word “polytic” is used as a word for “hard”. In order to expand production, from the time of qin to the time of the birth of the qin, the use of tan for the purposes of tanning, i. E., to find and accumulate in the breeching of the salt ponds, through the exploration and technological accumulation of the qin, han, wei, jin, north and south, as well as the dynasty, by the time of tang dynasty, the country was strong and the chemically developed to refine the salt ponds, the techniques of which have evolved to the advanced stage of tanning, which can remove impurities and produce pure salt. In other words, such high-end sunburning is the true face of the tan. Its technical core is the division of salt fields into blocks by function, for example, some blocks are used to store halogenated water; some blocks are used for evaporation; and some blocks are used for crystallization. Such a classification, in addition to making the production process orderly, could be accompanied by a technology — the tan salt of nitro。
In january 2019, over 130 square kilometres of salt lakes in the west and west shipping city were collected by workers using manual and mechanical means. Chon hua
What's a nitro? Its chemical composition is called sodium sodium, which is a combination of sodium sulfate and magnesium sulfate in salt lake water. For most of the life of the salt ponds, the sheeting is both a by-product of salt and a necessary tool for salt production. Nitrometers have three main functions, i. E. Chemical change, i. E. The purification of halogen water through chemical reactions, and the removal of impurities; i. E. The heating of heat during the day and at night, which keeps the evaporation of the halogenated water constant; and i. E., the formation of full salt crystals to contribute to crystal resolution, i. E., to slow the growth of salt-eating crystals。
The most effective use is made by the use of sheeting, which is followed by the development of a finely refined operating process, known as the five-step salt production method, which allows the shipping industry to produce and sell the salt in sufficient quantity. It is not an exaggeration to say that there is no transport of the salt of the city without the nitro; the civilization of the saline lake is that of the technology on the nitro. British scientist lee joseph is impressed by what he calls a “living fossil” in the ancient history of chinese technology。
As early as ancient greece and ancient rome, europeans began to tan salt activities, generally reclaiming coastal areas or inland salt lakes and wells, introducing salt water into salt fields, using suntans to evaporate water and adopting salt crystals. This tan salt activity is largely consistent, both in time and form, with the budding period in china. But china’s high-end, step-by-step tan salt technology was matured at the beginning of tang, and europe would have to reach the end of the medieval century before it could produce a correspondingly regulated salt farm and tan salt technology. Technologies such as the use of nitro plates for decontamination are unique to shipping cities。
