Introduction to Yixiantian: The hinterland of Five Fingers Stone is surrounded by stone peaks, and the peaks are dependent on each other. The cracks in between are twists and turns, as intricate as a maze. Among them, the line of sky landscape is rare in China. It is the highest, longest and straightest crack among the five-finger stones. There is a poem praising it: "The most beautiful sky among the eight sceneries, the lines are closely connected with the clouds; the beautiful vines and peaks make visitors drunk, and the pleasures here are better than those of gods."
