Introduction to Zheng's Seventeenth House: Zheng's Seventeenth House was built by Zheng's ancestors who migrated from Xingyang, Henan to Zhenhai during the Southern Song Dynasty. After protective restoration and development, it has now become a folk culture tourist attraction and a base for the inheritance of traditional Chinese festival culture. The village is designed in a chessboard shape, and the overall buildings are connected into courtyards with buildings as units. It combines the atmosphere of the "courtyard" in the north and the exquisite pavilions in the south. It is the largest and well-preserved ancient building complex of the Ming and Qing Dynasties in China.
