Introduction to Yang Silangquan: According to legend, Yang Silang, a general of the Yang family in the Song Dynasty, went on an expedition with the army and passed by Yanzhi Mountain. He saw the rich water and grass, flowers, trees and beautiful scenery here. He immediately dismounted from his horse to take a rest, and inserted the spear in his hand into the ground. After the gun was pulled out from the ground, a clear spring quietly gushes out from the place where the gun head was inserted. The spring water is sweet and cool, and it flows all year round to this day.
