Introduction to the Immortal Couch: The four words "Immortal Couch" were inscribed by Kongzhan Taoist. It is close to the side of the rock and is refreshing and smooth. It is said that Ge Hong and his wife Bao Gu were collecting Chinese herbal medicines on the mountain when they were tired. This is where they rest and cool down in summer. This stone is less than six feet, but it is very strange. Legend has it that just lying on it for a while can not only relieve fatigue, but also cure backache and leg pain.
