The ancient well on top of the Five Dragons is called "Longjing". On a mountain peak at an altitude of 1,200 meters, there is a well with a water depth of up to two meters all year round, which is truly astonishing. According to the hydrogeological data of Wudang Mountain, the foundation stones of the Wudang Mountain water system are composed of mica schist and metamorphic volcanic rocks, etc. Groundwater is scarce, with only a small amount of fissure water. It seems unlikely that there will be such an abundant water source on the top of this high mountain. However, there was an exception on the top of the Five Dragons. Perhaps it was this exception that was discerned by the ancients, and thus the legend of this place being the "Residence of the Five Qi Dragon King" emerged, along with the dragon well and the fantasy of locking the dragon with a "dragon locking stone".
We can say that the discovery and utilization of Longjing tea is a shining point of the wisdom and ingenuity of the ancients, as well as their outstanding creativity in ingeniously utilizing nature!
