In front of the colourful, patchwork of fairy pools is a unique landscape in the karst landscape, the scientific name of the calcification pool, because the groundwater is rich in calcium ions, slow water flow, with the gradual seepage of water from the cave, the carbon dioxide in the water quickly disappeared, lost carbon dioxide calcium bicarbonate became insoluble calcium carbonate, on the spot deposition, over time, gradually formed the first barrage! --The first dam was formed over time. When the spring water crosses this side stone dam and flows to the next ground protrusion, this ‘damming’ process will be presented again, and over and over again, the ‘natural terraces’ we see unfolding step by step will be formed. Combined with modern sound and light technology and scenic spots, it adds a mysterious colour to the place, presenting a beautiful terrace picture scroll.
