Introduction to Tugu Ancient City: Tugu Ancient City is located 21 kilometers southwest of Zhoucun City. It is named after the local area where Tugu vines are abundant. During the reign of Emperor Gao Qi, it was incorporated into Weiguo County. After Tugu County was abolished, four villages were successively established around the ancient city. They were distinguished by the surnames of the residents, and the villagers used to collectively refer to them as the ancient city.
