Introduction to Longquan Well: There is a well behind Bafeng Tower - Shenlong Ancient Well, which is the source of life of Shenlong Mountain. The magic of this well is that: first, it is a well dug out of a complete stone; second, there is no higher mountain than it within ten miles. The water from the wells and springs is sweet, and it lasts all year round even if there is severe drought in all directions. With this water, it is possible to build a fortress on Shenlong Mountain to enable it to be attacked and defended.
