Cuijiacun is also called Cuijiazhuang by local people. In the early years of Hongwu in Ming Dynasty, three brothers, Cui Shi from Hongdong County, Shanxi Province, moved to the west bank of Dayu River (formerly known as Dawei River) in Wei County, and were named Cuijiazhuang after their surnames.
Cui Jia grinds sesame oil. Legend has it that Cui Shi was clever and handy at that time. He grinds the fried sesame seeds into paste with a small stone mill, then puts the sesame paste into a large pottery basin, pours in a proper amount of boiling water, and stirs it in the basin with a wooden pole. When a layer of oil floated in the basin and gave off a fragrance, the wooden pole was put down, and the pottery basin swayed back and forth on the wooden pole, and the oil layer was continuously thickened. Then scoop out the oil with a wooden spoon, put it in a container and sell it in the market. After Cui's continuous improvement of technology, the sesame oil made by the small mill was rich in fragrance and gradually introduced into the palace, and was named "sesame oil" by the emperor. Because this kind of sesame oil is ground with a small stone mill, people also call it "small ground sesame oil". Later, people nicknamed Cui "Cui" and he became the ancestor of Cui. The grinding technology of small sesame oil has been passed down from generation to generation, and it has a history of more than 600 years.
