Ancient tombs in China are a complex cultural phenomenon, and the choice of tomb sites depends on geomantic omen. Since ancient times, people have attached great importance to the choice of cemetery. The factors considered by the ancients in choosing a cemetery are: First, the geomantic omen near Beijing is naturally good; Second, hometown, fief or ancestral home conforms to the traditional concept of returning to the motherland; Third, the place of death, such as anywhere, battlefield, etc. This usually depends on the situation, such as traffic restrictions; Fourth, other places, such as the place I yearned for before my death. However, it is generally necessary to choose a place where "there is a photo before, and there is a place to lean on", that is, there is running water in front, there are peaks to lean on, and the mountains in the territory are green, which means that the cemetery should be surrounded by mountains and water. Of course, there are many other pressures. To this end, I extract the following passage for the landlord to choose:
First of all, it is necessary to make clear the water inlet and outlet directions of the cave, determine the general orientation of the land god according to the combination of the cave orientation and the five elements of gold distribution, and determine the accurate orientation of the land god according to the surrounding environment of the cave. This kind of land god not only conforms to the situation of geomantic omen in Yin house, but also conforms to its principle. Make its tomb more in line with the requirements of geomantic omen, so as to better benefit future generations.
