2. Water: Since it is a treasure trove of geomantic omen, there must be mountains and water, and there are many stresses on water in geomantic omen. Water must be in front of the place, and it must not be stagnant water. It must be a flowing river, and it must not only flow to the place, but also flow around the place, which will be of great help to the operation of Feng Shui.
3. Land: The so-called land refers to topography, landforms and landforms. For example, if there are many rocks on the surface, the geomantic omen of this landform is very bad, and the terrain should be flat, neither too high nor too low, which will be unfavorable to geomantic omen.
