Introduction to Chiakida: "Chiakida" is one of the five unique features of Snow Creek Cave. The semi-circular stone dam in the water is a common geological image in karst caves, but Chiakida with its constant flow of water, complete structure and large area is extremely rare in other caves, so it is also a unique feature of Xuexi Cave. The flowing time of thousands of years, the days of getting up early and returning late to chase the sun, in a mysterious and dreamy cave like Xuexi Cave, hills and stacks of stone fields of different shapes have been cultivated.
