Ziyun Pavilion was built in the Sui Dynasty.
Yang Xiong studied in Mianyang, and the Sui Dynasty built Ziyun Pavilion in Fenghuang Mouth of Xishan. Li Bai once said in a poem: "Memories in the morning are like a stage, and dreams in the night are like a cloud pavilion", which shows that the cloud pavilion occupies a very important position in the poet's mind. There is a famous sentence "Zhuge Lu in Nanyang, Ziyun Pavilion in Xishu" in Liu Yuxi's "Humble Room Inscription", which makes Ziyun Pavilion famous for generations to come. However, Ziyun Pavilion has already decayed. Ziyun Pavilion, rebuilt on the old site in 1980s, has a height of 2 1 m, a building area of 1.300 m2 and 28 columns at the bottom. The pavilion is heavy and the cornices are towering. Because it is located at the top of the Phoenix Mouth, it rises on three sides and is very dangerous.
