Introduction to the Hall: The Sanqing Hall is dedicated to the Three Pure Ones, namely Yuqing Yuanshi Tianzun in the middle, Shangqing Lingbao Tianzun in the east, and Taiqing Daode Tianzun in the west. Taoism believes that the Three Pure Ones are all incarnations of Yuanshi Tianzun. Therefore, there is a saying that "one Qi transforms three pure states".
