Chapter 30 (2/2)

After Yao, Shun and Yu became the emperors of unified China, they chose Pingyang (Linfen, Shanxi Province), Puban (Yongji, Shanxi Province) and Anyi (Yuncheng north, Shanxi Province) near Yanchi to build cities, which were historically known as Yaodu, shundu and Yudu, just for the sake of protecting Yanchi.

In ancient China, salt was called ”Zhuolu”. Because of the homonym, ”Zhuolu” gradually became ”Zhuolu”, and later became ”Zhuolu”, so later generations called the war of ancestors fighting for salt (brine) pool ”Zhuolu Zhongyuan”, which later became the pronoun of war.

In ancient Central and South America, there was a highly developed Mayan civilization. In 1000 BC, the Mayans were able to produce sea salt by solar evaporation in Yucatan Peninsula.

At the beginning of the 16th century, the Maya had a huge industry and extensive trade related to salt. The scope of trade included not only salt, but also salted products processed with salt, such as salted fish and leather.

The Maya civilization flourished because of the production and trade of salt. Similarly, it was the rich salt resources of the Mayan civilization that caused the European colonists to covet. Then the Spanish colonists who controlled the hot weapons raised their butcher knives to the friendly and hospitable Mayans. Continuous wars broke out in central and South America, and finally led to the historical tragedy of the extinction of the Mayan nation and the annihilation of civilization.

In the American War of independence, the British Army seriously weakened the combat effectiveness of the Washington led army by cutting off the supply of salt, and restricted and delayed the process of American independence.

During the American Civil War, the northern army led by Lincoln destroyed the salt fields in the south, resulting in an extreme shortage of salt in the south, which seriously affected the combat effectiveness of the southern forces and accelerated the war process.

Thus, the history of salt is not only a history of human civilization, but also a history of human war!

At the same time, it is enough to prove the importance of salt to human beings.

Now, let alone North America, even in Europe, salt production is extremely low. In fact, a very important reason for the hundred year war between Britain and France, which lasted for more than 100 years, was salt.

In this era, salt is also in great demand in Europe, especially in North America. The main reason for this situation is that the technology of human salt mining and salt making has not yet reached the standard, so the situation that salt is not enough now is formed.

As we all know, the cost of using sea water to dry and boil salt is very high. Even in later generations, the cost of sea salt is much higher than that of well salt. Whether well salt or rock salt, most of them are mixed with many impurities. If they are not refined, the salt produced is not only bad in taste, but also poisonous, which can kill people.

So now in Europe, the amount of well salt is not much. All the salt is supplied to the nobles. The common people and soldiers in the army mainly use sea salt.

But salt drying is greatly restricted by the weather, so there is not enough salt in Europe.

However, Europeans don't know how to refine well salt and rock salt, and they don't know how to remove a lot of impurities, but they know

Squatting in front of the small salt mountain, the stone bear squinted and thought, and his face showed that strange smile unconsciously.
