This word first appeared in bronze inscriptions during the Warring States Period, and its original meaning refers to table salt. The chemical component of table salt is sodium chloride.

Jiang was created accidentally by Fan Li. According to legend, when Fan Li was seventeen years old, he managed the kitchen in a rich man's house. Due to lack of experience, the food is often not cooked to your satisfaction and leaves a lot of food left over. Over time, it becomes sour food. To prevent the owner from discovering it, Fan Li placed the food in the storage room. However, there is no airtight wall. This was eventually discovered by the rich man. The rich man scolded him and gave him ten days to turn the sour food into something useful.

Smart Fan Li first processed the food with green and white hair, then dried it in the sun and fried it in a pot to remove odors and kill bacteria. He added some warm water and stirred it into a paste to feed the pigs. The rich man was very happy to see the pigs eating happily. Later, a young farm worker joked with Fan Li and put the food in noodles for Fan Li to eat. Unexpectedly, the noodles were very tasty. At this time, Xiao Changgong revealed the whole story. Inspired by this, Fan Li created a delicious sauce using this sour and sour food.
