Songjing, a famous attraction in South Australia, the locals took us in, free of charge. Songjing, as the name implies, is the well that was opened in the Song Dynasty. The magic of Songjing is that although it is on the beach, it is a freshwater well that will never die. We tasted the well water, really amazing, so sweet, so curious to ask about the situation. Why is the well close to the sea, will not have the salty taste of the sea for years? It is said that some people believe that from the scientific reason analysis, at that time, three wells were drilled on the rocks on the side of the mountain, and facing the spring, so the spring water source is constantly. And because there are two heavy stone rocks at the bottom of the well, the spring is on the top, and the stone rocks at the bottom block the penetration of the sea water, the water quality is sweet. When the tide poured into the well, due to the large proportion of the sea water, it leaked out of the rock formation after sinking, and the spring water above was still light. Recommended: must go to the attractions, five-star recommendation.
