Introduction to Huoquan: There is Huoquan right outside the gate of the lower temple. According to Li Daoyuan's "Shui Jing Zhu", Huo Shui comes from Huo Tai Mountain and accumulates water to form a pool, with an unmeasured depth of tens of feet. Huoquan now consists of Haichang, Fenshui Pavilion and Stele Pavilion. The sea farm is a water source pond with an area of ​​about 80 square meters. It is built on the mountain and the source is enclosed. It flows four cubic meters per second and irrigates more than 100,000 acres of grain fields.
