It's well-known. It happens to be rainy and cloudy, so you can imagine that the water is enough. After entering, I feel really handsome geological landscape. When we went there that day, nobody was there, so it was still quiet around. If we could hear the sound of water, we could feel the sound of water pushing forward and rushing towards the rock walls and riverbeds. This is the power of nature, dripping through the rocks, slowly forming a road, go down the stick.
