Well salt refers to salt made from underground natural brine and salt made from underground rock salt, which can be divided into well salt and mineral salt. Well salt is rich in natural minerals. It comes from underground, with relatively little pollution, so it contains less impurities.
The largest well salt production base in China is located in Zigong, southern Sichuan. Known as the "Millennium Salt Capital", it has a history of well salt mining and production for nearly two thousand years. From the Zhang period of the Eastern Han Dynasty, through the development of the Tang and Song Dynasties, the salt produced in the heyday of the Ming and Qing Dynasties can be used by one tenth of the population in the country. Zigong is still one of the largest well salt production bases in China, with an annual output of over 2 million tons.
In addition, in Yexian County, Pingdingshan, Henan Province, there is a salt field with an area of more than 400 square kilometers, with 330 billion tons of rock salt reserves, which can be eaten by the people of the whole country for 33,000 years. Yexian rock salt is not only rich in reserves, but also has moderate thickness of coal seam, which is very beneficial to mining and processing. Well and mineral salt products rank first in China, and Yexian County is known as the "Rock Salt Capital of China".
Jingyan culture
Zigong Yanbang cuisine is a representative of Sichuan cuisine, with unique flavor and cooking skills, which originated from the rich precipitation of salt culture. It is isomorphic with Xiaohe Gang, Shanghe Gang (represented by Chengdu), Xiahe Gang (represented by Chongqing) and other Sichuan cuisines, forming a world-famous and unique Sichuan cuisine culture, so the phrase "Eat in Sichuan and taste in Zigong" comes from this.
The prosperity of salt industry not only created the reputation of "Zigong Salt Capital", but also bred, inherited and gradually formed an important school of Sichuan cuisine-Zigong Salt Help Cuisine. Zigong salt, as a special raw material, has a unique flavor because of the unique diet of salt merchants and salt workers.
