Introduction to Xianyu Ridge: Xianyu Ridge, also known as Fairy Ridge, is located in Dieping Township. According to legend, Shen Zhenzhu, the wife of Li Yu, the grandson of Emperor Xuanzong of the Tang Dynasty, practiced and became an immortal here to avoid the "Anshi Rebellion". "Xian" refers to "Xiangu Li Cihui", and "Yu" refers to the place where food is stored. The two words added together make the place name, which expresses people's hope that "the fairy empress will subdue the demon to make this place have good weather and good harvests, thus becoming a granary."
