Introduction to the Stone Drum: Before the Huangchao Uprising in the Tang Dynasty, there was a stone drum on Shigu Mountain, six feet high, and the sound of knocking could be heard for dozens of miles. It is recorded in "Shui Jing Zhu" written by Li Daoyuan of the Northern Wei Dynasty. The magical stone drum has been "Lu Long pushed the drum into the pool", and the existing stone drum was first chiseled by Tao Zhu in 1965.
