Introduction to Feilaishi: Next to the dangerous cliff, a flat stone pillar more than 20 meters high stands on the edge of the cliff, just a stone's throw away from the steep wall next to it, with a stone gap in the middle that looks like a sharp axe. There is a large stone stuck in the sky above the stone seam. It is about to fall but not fall, as if it is falling from the sky, hence the name "Flying Stone".
