Hedong Salt Lake: Yellow Emperor and Chi You triggered, the Battle of Yan

The most famous lake in China and the oldest east of the river when the number of salt ponds.

Salt Pond on the east, Qian Mu, in the "Introduction to Chinese Culture," in this statement: "Solutions for county County near the famous Salt Solution, Central Plains tribes of ancient China compete for a common goal. Therefore, accounting for Salt Lake, and they said he had the qualifications of the tribal leaders together. "in order to compete Hedong Salt Lake, the Yellow Emperor and Chi You and Yan were carried in two wars, the history of the War and the famous Battle of Banquan. This victory in two wars, the Yellow Emperor firmly in control of the east salt pond, salt controls the lifeblood of the Central Plains region, and ultimately become the tribal leader, was "the Chinese ancestors," the noble status.

East of Salt in Salt earliest use of resources, initially adopted a "fish Law": the light of day exposure, natural crystal, set workers fishing mining, salt production all rely on the forces of nature. Salt Pond is located east of North China in summer one of the hottest, the highest temperature reached 42.6 ℃, light is also very rich in resources, the annual precipitation is about 520 mm, evaporation is up to 2300 mm. With the south wind, is a prominent feature of east salt pond. Section through the valley of the south wind, due to the narrow tube effect of wind strengthened and violently swept through Salt Lake, blew away the vapor generated when drying the brine, so that exposure to the sun more effectively brine, brine evaporation continued to accelerate the precipitation of salt crystals . Violent south wind here and to what extent? From the following examples can be seen, in the village of Salt Lake Chi (now village of longevity), the residence is no longer the traditional northern-style faces south, but must be built to sit northward to escape the south wind.

Since fish is the natural formation of salt crystals, crystal containing magnesium and other impurities, so that the salt they taste bitter, so "bitter salt," was another name for salt is the east.

To the Eastern Han Dynasty, Dong Salt started to take "Ken stretch of water drying method", which is artificially cultivated for the patch, build a stretch of land next to the ditch, the water through the ditch into the furrows until the water evaporates, salt crystals . Ken stretch of water at this time the sun is still in the early law, without the filter will be the introduction of salt brine, the salt in the soil, so get the salt is still bitter.

The Tang Dynasty, salt workers began to use fresh water with a brine salt, the water temperature is low, the brine temperature is high brine temperature had been adjusted, magnesium sulfate, sodium and other impurities to break out of the formation of "Glass Plate," crystal cardigan Glass panel built in, so that the salt produced is no longer bitter, but also greatly shorten the time crystallization of five or six days to salt, this is epoch-making changes in salt production, solar salt production in the history of the world also leading position.

The next thousand years in the east salt pond salt production in China has been occupying an important position, glory to the salt tax was only one of the national fiscal revenue accounted for 1 / 8. To the mid-Qing Dynasty, due to brine desalination, salt production capacity of east Salt rapid decline, and with modern technology, sea salt production and transportation costs, gradually withdrew from the east salt pond salt production stage.

Now the main east salt pond "Chinese Dead Sea" tourism brand, the new regimen was developed black mud, floating in the Dead Sea, mineral water treatment and other tourism and entertainment projects, sought after by many tourists. The salt pond has incense in the "pool of the temple", and now the "east Salt Museum", although has a very high historical value, but it is doors to cold, not popular. It seems that in the history and enjoy the reality of the memorial, the people more to choose the latter. (Adapted from "National Geographic" 3 2011 The author / Xiao Ming)
