Introduction to the Water Curtain Corridor: The Water Curtain Corridor is located at the bottom of the dam, about 50 meters long. The corridor is winding and quiet, warm in winter and cool in summer. Especially in rainy summers, when the water level of the reservoir rises, water gushes out from the five holes in the dam and falls into the pool below, with a height difference of more than 20 meters, forming a spectacular artificial waterfall. The corridor behind the waterfall It has become the coveted "Water Curtain Cave". In addition, there are 12 holes in the corridor, which represent the twelve months of the year, as well as the twelve constellations and zodiac signs.
