What is the difference between left water and right water in geomantic omen?

Feng Shui mainly talks about the left dragon and the right white tiger, and the left water falls to the right, indicating that the dragon is high. Because water flows from high to low, it is called left water falling to right, right water falling to left, and so on. This difference should be carefully studied. Geomantic omen theory is actually a knowledge that time affects space, and different spaces produce different fortunes.
