Introduction to the Qiyun Hall: The Qiyun Hall, also known as the Xiang Hall, is the main building in the mausoleum. It is the hall where the emperors of the Qing Dynasty visited the mausoleum, held the mausoleum ceremony and offered sacrifices in peacetime. The hall is a glazed building with a single eaves, resting on a mountain, with 3 bays in width and 4 bays in depth. There are 8 rows of dragons playing with pearls on the main spine. The two characters "sun" and "moon" are carved on the sword handles at both ends, which means "shoulder shoulder". "The sun and the moon dominate the world" and "the ancestors and gods protect the country like the sun and the moon forever", which is unique among the mausoleums in Guan Nei.
