Required. Guo Pu's "Burial Book" once recorded such a passage: "When a person receives his parents, his original body receives Qi, and his body receives shade. What covers life is the gathering of Qi. What condenses becomes bones, and what is left is left alone after death. Therefore. The buried person's Qi is absorbed by the bones, which is the way of creation of Yin. The Sutra says: When the Qi is strong, the ghosts will be blessed. This passage can be regarded as the principle of Feng Shui. I understand it to mean that the human body is formed by the body. Born from parents' ancestors, the "qi" of parents and children is of the same origin. Therefore, if the ancestors' bodies receive the earth's Qi, then the child's life will be in a more auspicious state. This is also "the Qi is strong and the Qi should be responded to." Therefore, even if the ancestors are cremated, the ashes still retain Qi, so after the urn is buried, even if it is only partially, there is still a Qi induction, so Feng Shui also needs to be paid attention to.
