Introduction to the Seventh Spring in the World: The spring is located in the center of Chunyang Taoist Temple, surrounded by a centuries-old elm tree. The spring water contains many minerals and is used to make tea. It is fragrant and refreshing, sweet and delicious. When the tea is poured into the cup, it can protrude out of the surface of the cup one meter thick without overflowing, and it can float coins. Visitors who watch and taste it are all amazed.
