Introduction to "Stone Bells and Drums": In Taohuayuan Cave, water drips like beads, and the tinkling sound is like a dripping copper pot. When you tap on the stone bells and stone drums, the sound is clear and sweet. This is one of the eight sceneries in the cave, "Stone Bells and Drums" . There are many stone carvings on the stone walls in the cave, but they are all blurred and difficult to distinguish due to their age. However, high up on the left side of the end of the cave, the simple and powerful four characters "Taikou Collection" are still clear.
