In He Ming Mountain, there are two brooks, one running from the east, and the other from the west. In an old literature from the Ming Dynasty, a poet described the flow of water was like that of a current from the flapping wings of a crane. As the brooks are located right below the Tian Zhu Peak (天柱峰), they are also named as the “Dual Dragon Brooks” in the Qing Dynasty. During that time, a temple known as Tai Qing Gong (太清宫) used to be located on this mountain peak, below which was a big cave that allowed water to flow through. When the water level rose in the east brook, only turbid water would flow into the west brook, and vice versa. It was also known as the Dragon Pond.
