During the reign of Shunzhi in Qing Dynasty, there was a vinegar shop named Zheng in Chengnan Street, Xincai County. The shopkeeper is very clever and has a set of skills and experience in making vinegar. The vinegar he made is sweet and mellow, with a long aftertaste, lasting for a long time and getting more and more fragrant. Only a few drops are needed when eating, which is very popular with people. People come to the vinegar shop to make vinegar every day. Some people want to be jealous, but they always want to eat more. Every time they go to the vinegar shop to make vinegar, they always want the shopkeeper to make more, but the shopkeeper is always stingy and refuses to make more. These people nicknamed the shopkeeper "Old Turtle One", and since then, "Old Turtle One" has become synonymous with vinegar shop. Later, the shopkeeper simply changed the signboard to "Old Turtle-Vinegar Shop". Since then, Laojia vinegar has enjoyed a high reputation in the Central Plains with its excellent quality and unforgettable brand name.

"Old Bieyi" has a derogatory meaning in Henan dialect. During the Cultural Revolution, the descendants of the old Bieyi firm were criticized many times, and even the signboard of the "Old Bieyi Vinegar Shop" left over from the Republic of China was doomed and destroyed in the "breaking the old four".

According to the elders, the old shopkeeper's two words "not seeking a good name, but seeking a good name" and "selling vinegar without conscience" are the main reasons for the extension of this name so far, which is also the essence of the old turtle vinegar industry culture.
