Shi Er Bei Hou Underground Crack Scenic Spot

Shi Er Bei Hou Underground Crack Scenic Spot boasts the only large subsurface fracture in a cave in China. The fracture gradually widens from top to bottom, and the narrowest part allows only one person to pass. The cave is divided into upper, middle and lower layers and is connected to others through the underground river. The cave has a constant temperature throughout the year, so it feels warm in winter and cool in summer. It has fresh air and is a natural oxygen bar, with high content of negative oxygen ions.
