Zaozhuang, the resident of the municipal government, formed a village in the Tang and Song Dynasties, and was named Zaozhuang because of the large number of jujube trees. In the early years of the Ming Dynasty, the imperial court allowed private mining. In the truffle area, "villagers dug mountains to get stones, used grinding as grinding, and dug wells to get coal for salary". With the exploitation of coal, immigrants gradually moved to live around "Yao Bei Kiln". In various settlements, people either use surnames or names such as village records.
