Introduction to Sanqing Hall: Sanqing Hall is the main hall of Xuanmiao Temple. There is a vertical plaque more than one meter long in the middle of the front of the hall, which reads "Sanqing Hall" in three large block letters. It is a tribute to Jin Zhijun, the Taifu during the Kangxi period. Under the vertical plaque, there is a horizontal banner with the four characters "Miao Yi Tong Yuan" written with vigorous writing. It was also written by Jin Zhijun, but the original has been lost and is now written by Xie Xiaosi. The main hall has nine bays, with double eaves and mountain style. It is 44 meters wide and 25 meters deep, with a total area of ​​1100 square meters. It is a wooden building in the Southern Song Dynasty. In the middle of the roof is a three-piece iron halberd, which means a three-level promotion. The dragon head was carved in the Song Dynasty and is about 3.5 square meters.
The three pure gods in the hall are mainly worshiped, namely Yuqing Yuanshi Tianzun in the middle, Shangqing Lingbao Tianzun in the east, and Taiqing Daode Tianzun in the west.
