Baoning vinegar was created in the late Ming and early Qing dynasties, and its original trademark was "One Shoe". Because the founder of Baoning Vinegar was a refugee named Suo Yiting from Shanxi. He was dressed in the same clothes, one foot was barefoot, and the other was wearing a fishtail shoe (a broken shoe without a heel). , his special skill is making vinegar. Later, a wealthy family found out about it and hired him to make vinegar as a technician. He personally went to the mountains to collect herbs and make vinegar koji, using wheat drums as raw materials and water from the Jialing River to brew vinegar. The vinegar he brewed was moderately sour, mellow and palatable, and was very popular, so he named it "One Shoe". Later, because the name was too rustic, it was renamed "Baoning Vinegar" (Langzhong was governed by Baoning Prefecture during the Ming and Qing Dynasties).
