Good feng shui contains the potential of "wealth" and "treasure". Feng shui survey is to find a treasure trove of feng shui. The criteria of geomantic treasures include geographical location and geomantic omen. The standard of geographical location is that there is a backer behind, a left green dragon and a right white tiger in front of the mountain, a hall in the middle, winding water, hidden atmosphere and affection around.
These concepts actually include geography, environmental ecology, hydrogeology and so on. The management of Feng Shui and Qi is extensive and profound, and there are many ancient books collected in Siku Quanshu, such as burial books, dragon shaking sutra, Tianyu sutra, Qingnan Gaoyu compass and so on.
For example, a few words in the third volume of Tianyu Classic (biography): Dry mountain reaches water, and dry peak is the champion. Maoshan Maodi, Maoyuanshui, is richer than Shi Zongbi at once.
From noon to noon, the generals will be in the frontier. Kunshan Kun flows to Kun, and wealth will never stop.
It can be known that in order to enrich and highlight, we must consider five aspects: dragon, cave, sand, water and orientation.
