Hupao Mengquan is located in the south of the West Lake, in Dinghui Temple in Daci Mountain. The name of Hupao came because of Mengquan. It is legendary that the high monks of the Tang Dynasty lived here emptyly, and later was ready to move away due to a shortage of water. One day, he received God's instructions in his dream: there is a boy spring in Hengshan, Nanyue, when two tigers are sent, and the fruit sees two tigers running Cuiyan as a cave during the day, and the stone wall gushes out of the spring water, and the tiger runs through the dream spring from this name.
