The Feng Shui of the land studies the surrounding nature, hills, vegetation, waterways and roads that combine harmoniously or not.
The energy that flows through your home comes directly from the environment around the house.
Evaluating the Feng Shui of a place consists in studying the effect of the energies of the external environment (orientation and shape of the surrounding houses, presence of water, vegetation, roads, industries...).
A feng shui site that meets all the criteria of the San He system is ideally called the Dragon's nest or lair.
