In the Urgent Chapter written by You Shi, who was in charge of eunuchs in the Western Han Dynasty, there is a saying of "radish salt soy sauce"; In the Eastern Han Dynasty, Cui Mang wrote the Moon Order for Four People, saying that "April 4th can be sour cream".

In the Eastern Han Dynasty, vinegar was not only edible, but also used as medicine. According to legend, Zhang Zhongjing, a famous doctor in the Eastern Han Dynasty, treated yellow sweat with "Huangqi Baiyao Guizhi Kujiu Decoction".
