Introduction to Nuanquan Gou: There is a small ravine opposite Xuanyuan Temple. There is a pool of spring water halfway up the valley, so it is called Nuanquan Gou. At that time, this small ravine was uninhabited and had no name. Only after the Yellow Emperor settled in Qiao Country, people lived in the ravine. At that time, the leaders of the tribal alliance and the nearby people used the spring water here all year round.
