Guo Pu said in "The Burial Sutra": "The Sutra says that the earth has four forces, and the Qi comes from all directions. Therefore, the burial is with a green dragon on the left, a white tiger on the right, a red bird in the front, and a Xuanwu in the back. Xuanwu bows his head , the red bird dances, the green dragon meanders, the white tiger tamely bows. The situation is reversed, the law is broken, so the tiger squatting is called holding the corpse, the dragon standing is called jealous of the master, Xuanwu does not listen to the sound and rejects the corpse, and the red bird does not dance and flies away. , Tu Gui measured its position, and the jade scale measured its distance.
"The tiger squatting is called holding the corpse." In layman's terms, it means that the sand guarding the right side of the hole is high, as if looking back at the hole, it is holding the corpse for the white tiger. . Some make the right sand guard short and extend horizontally near the hole, which is called white tiger holding the corpse.
