Introduction to the underground sacred spring: The highest peak in Qingdao city - Taiping Mountain. The mountains are rugged and rocky, but they are suitable for the growth of various precious trees. The dense vegetation is known as Qingdao's "green lung". These vegetations take root under the stone layers and feed on the underground rivers surging deep in the mountains. These underground rivers not only nourish the greenery of the entire Taiping Mountains, but also quietly penetrate into two famous places. One is the original old well of the Tsingtao Beer Factory, and the other is 20 meters underground in the Yan'an 2nd Section of the Qingdao Civil Air Defense Project. The rice gurgled out, becoming a mysterious place. This underground spring still maintains its mysterious appearance, neither increasing nor decreasing. It is known as the treasure of the wine museum - the "divine spring". No matter how many people drink from this "sacred spring", the water level always remains unchanged. Even if the water consumption is very large for a period of time, after a while, the water in the pool will return to its original level, which is very strange. Its water quality is sweet and delicious, rich in minerals and trace elements, free of chemicals and microorganisms, and highly pure. Tea brewed with "Shenquan" will not leave any tea stains at the bottom of the cup.
