Introduction to Cuiyin Pavilion: Cuiyin Pavilion, also known as Cuiyun Pavilion, is a famous scenic spot in the Huaqing Palace of the Tang Dynasty. There is a quatrain written by Li Gu of the Song Dynasty that praised the mountain: "It's so old when I say goodbye to Lishan Mountain, and the forest flowers are still embroidered on the peaks. I returned to find a newly opened road that day, with faint moss marks under the green shade."
