Introduction to Yinhe Spring: Yinhe Spring is located on the south side of Fanghe Pavilion. Before the Northern Song Dynasty, Yunlong Mountain was called Shifoshan, and Yinhe Spring was called Shifojing at that time. Later generations changed its name because it was close to Fanghe Pavilion. Yinhe Spring is famous for its deep water and sweet water quality. Su Shi once wrote a poem praising this spring.
