Don't choose graves on grey walls on steep hills. In order to save land, some cemeteries build so-called ashes walls, or build tombs on steep mountains. Looking down, it's deep and steep. You can't choose such a grave. If you choose, your family will have no foundation, and your popularity and wealth will decline.
You can't choose a place near the cemetery wall, which is easy to cause controversy and conflicts between future generations.
If the cemetery grave is used by others, don't choose it. If you choose, you will be suspected of taking advantage of others' shady activities, and your family will be supernatural.
It is lucky to choose a place more than one square meter, with edges and wires, forming a right angle. Try to establish boundaries in the cemetery. A tomb without boundaries is easy to make the Lord and others stiff.
