Introduction to Guanyin Waterfall: Guanyin Waterfall is the second largest waterfall in Longchuan, with a drop of 58 meters. Looking up at the Guanyin Waterfall from the Xianfan Bridge, there are two large and small strange stones in the middle. The larger one on the west side is Guanyin Bodhisattva facing the wall and chanting Buddha quietly. The smaller one next to her is the "Dragon Girl" who serves her. I gave a son to someone who "does good deeds and accumulates virtue". The content of negative oxygen ions in the air in Longchuan Grand Canyon reaches 8,000 to 10,000 per cubic meter, which is dozens of times that of large and medium-sized cities. Guanyin Waterfall is one of the areas with the highest concentration of negative oxygen ions in Longchuan.
