Source introduction: The butterfly spring covers an area of ​​more than 50 square meters. It is a square spring pool with marble guardrails around it. The spring water is as clear as a mirror, with strings of silver bubbles emerging from the bottom of the spring and splashes of water; it is cool, sweet and refreshing. This spring water is the result of Cangshan Mountain turning snow. Not only is the water quantity stable, but the water quality is also very good. The spring water is rich in minerals and is beneficial to human health. There is a local proverb: "Drink some butterfly spring water and you will be drunk for thousands of years."
