Introduction to the Spring of Youth: A fault zone formed by changes in the earth's crust six thousand years ago. A natural spring water source is exposed in the cliff. It is located at the foot of the Tea Mountain. The spring water flows along the creek from the side of the village. The clear water irrigates tens of thousands of acres of grain. The field gave birth to centenarians in the village, so it was named "Fountain of Youth". At the same time, tea and Taoism have a deep connection. According to legend, Lu Dongbin practiced here and made tea with spring water, from which he realized the health-preserving principles of spring water.
