What does the land of turtle rest mean in fairy tales and anecdotes! ! !

Taoist language. It is said that breathing is like a turtle, and you can live forever without drinking or eating. When I said it, I thought that when the tortoise slept, its breath came out of its ears, so it lived forever. The language version of Jin's "Bao Pu Zi Dui Su": "Fairy scriptures are like turtle breath, aren't they?" Tang Li Bai's "Dai Shoushan answers the biography of Meng Shaofu": "It's a turtle's rest, hidden in this mountain." Yuan Cen Nanqing said in "Harmony": "I am always pregnant, but when there is a dispute in the world, I must sit at a banquet and learn from the turtle." In the Qing Dynasty, Yao Nai's poem "Dingzhou Encounters Snow" said: "When you enter the ground, sit on a turtle's breath, let the curtain go down and do whatever you want."
