The two walls of the ditch have a strange shape of limestone, and a clear stream at the bottom of the gorge has fallen and jumped, forming many underground waterfalls in the strange stone clumps. The sound is like a wave and it is endless. Looking up at the scenery in the cave, the water beads on the top of the cave hang like pearls. There are several small holes in the cave that extend inwards and are unfathomable.
