As an indispensable condiment in daily life, salt has reached an irreplaceable level. It has a very long history. As early as ancient times, clever ancestors invented a series of methods to purify edible salt under the condition of backward technology. Let's explain them one by one.

According to legend, during the Yanhuang period, an early wise man, Su Sha, pioneered the method of boiling salt in seawater, which was called "Su Sha as edible salt" in history. This is the earliest recorded method of salt purification in ancient China. Later people called it "Salt Sect".

Among the cultural relics unearthed in Fujian in 1950s, there were salt frying utensils, which proved that people in Yangshao period (about 5000-3000 BC) had a preliminary ability to fry salt.

In the early days, salt was directly put on the stove rack and cooked in an iron pan. This method consumes fuel and time, making the price of salt higher. So in the Zhou Dynasty, there was an official named "Salt Man". Li Zhoutian's Yan Guanren describes being in charge of salt administration and managing all kinds of salt affairs.

Historically, policies on "salt" have also emerged in an endless stream. Emperor Wu of the Han Dynasty enacted a salt law, monopolized official salt and prohibited private property. During the Tongzhi period of Qing Dynasty, Qiao Songnian, a salt messenger, built a "salt temple" in Taizhou to worship Su Sha who cooked the sea as salt.

Then, in areas with natural brine, the production method of "burning charcoal first, splashing with salt well water and scraping salt" is adopted. At the end of the Warring States period, Sichuan began to dig wells, take brine and fry salt. Qi Guanzhong implements the policy of "official mountain and sea", that is, salt is made by the government and all products are transported and sold by the government.

By the Sui and Tang Dynasties, Shanxi Salt Lake had begun to take shape and began to adopt the new technology of "reclamation and irrigation". The ancient salt-making technology in China developed rapidly. During the Song and Yuan Dynasties, Fujian could make salt by "drying salt".

In the Song Dynasty, there was a major breakthrough in Sichuan, namely, well salt mine. Clever working people use drill bits to mine well salt mines. From the Ming Dynasty to the Qing Dynasty, the technology of this craft gradually matured.

This shows that the wisdom of our ancient working people is infinite. This is an important guarantee for China to last for 5,000 years. The above is the whole outline of the ancient salt-making method in China. I hope I can help you.
