Introduction to the main hall: The main hall is the main building of the ancestral temple. It is the most important and earliest building of the ancestral temple. It adopts the architectural style of the Song Dynasty and uses a large number of brackets to extend outwards to protect the pillars below from damage. Eroded by rainwater from the south, the structure is solid and thick, and the appearance is majestic and steady. It is a rare example of Song-style brackets among the existing ancient buildings in my country. The hall is surrounded by walls on three sides, with an open south side, three bays in width and three bays in depth, and sixteen pillars. There are corridors on the left and right sides of the front hall, connected to the front hall, and a patio in the middle. Inside the hall is a majestic bronze statue of Emperor Zhenwu (North Emperor) made in the Ming Dynasty. It is seated with disheveled hair, quiet and solemn, with painted dragon robes and shining golden light. It is the main statue worshiped in the ancestral temple.
