Introduction to Sangu Ancestral Hall: It was built during the Kangxi period of the Qing Dynasty. The hanging flower gate is a single-eave hanging mountain-style building with carved beams and painted pillars, and upside-down flower buds under the front and rear eaves. The plaque "Three Visits to the Temple" on the door was written by the contemporary Lu Jiaxi, and the couplet "Two tables reward three visits, a pair will last a thousand years" hangs on the doorpost. When you look at the temple three times, you will see tall green cypresses, green grass, and a vast and deep courtyard. The surrounding walls are covered with inscriptions, so it is known as the "stele wall".
