Introduction to the Five Porch: The Five Porch is composed of several ancient house doors, which are arranged along the north bank of Lingqu Canal to form a stone corridor. The first gate is the most delicate of the five porches, and its origin cannot be verified. This second gate was built during the Qianlong period of the Qing Dynasty. It was built by the people to commend Zhu Yuanzhang's 17th grandson Zhu Rong. The third porch is said to be the chastity archway for Tang Xuan, the first-grade imperial concubine in the Northern Song Dynasty. The fourth porch is the porch in front of the original Guandi Temple in the county seat. This fifth porch was originally the porch of the Zeng family courtyard of a wealthy family in Xing'an.
