Introduction to Xuantian Palace: Xuantian Palace is the main hall of Yuntai Temple. It has a magnificent and gorgeous building. In front of the palace door, a rolling dragon wraps around pillars, and a golden boy wearing a red silk ribbon rides on it. The gate is said to have been built by Lu Ban during the Warring States Period, and there is a proverb that goes, "When you open the door with your left hand, the golden rooster crows, and when you close the door with your right hand, the phoenix crows."
