Introduction to the Thin Line of Sky: The "one" shaped rock crevice that runs across the top of Lingyan is 178 meters long, with the highest point being 49 meters and the narrowest point being 0.3 meters. It is one of the rare wonders of the Thin Thread Sky in the country. The line of sky starts from the roof of Fuxi Cave at the left end of Lingyan, passes through the roof of Fengdong, and ends outside the back wall of Lingyan Cave at the right end of Lingyan. The long and narrow rock waist formed by the rock crevice is called Bird Terrace. On the promenade, through a ray of skylight, you can not only explore the secrets of the cave under the rock, but also enjoy the scenery of Pavilion Rock and Blue Rock across the canyon.
