Ladies and gentlemen: What is the principle that our ancestors' houses are used to bring happiness to future generations?

Geomantic omen has the theory that the dragon is divided into nine potentials and five potentials, all of which are distinguished from the different trends of the mountain shape. There are three dragons in the earth vein, that is, the North Dragon, the Middle Dragon and the South Dragon all originated from Kunlun Mountain, which together with the former gave birth to the topography of China, which is of great significance for summarizing various forms and types. As for the description of the geomantic theory of Yin House, it is just like "people are entrusted by their parents, their bones are alive and their bodies are shaded", that is to say, the bodies of children and grandchildren are the parts left by their parents (ancestors), and their bones will be blessed if they are angry, so it is very important to find a lucky house for their parents (ancestors) bones.
