Lingxu is the name of the acupoint. The First and Second Classics of acupuncture and moxibustion and Moxibustion were published. Spirit, as opposed to ghosts, refers to the energy of the heavenly realm. Ruins, mounds, or ancient city ruins refer to the material emptiness and emptiness within the cave. The substance in this acupoint is a very small amount of water vapor that comes from the Shenfeng acupoint.
