What are the characteristics of gloomy places in geomantic metaphysics?
The places with heavy yin should be: gloomy, dark, cold, and children don't like to play. All kinds of animals, including poultry and livestock, don't like to play, and birds don't want to stay there. I also have such a personal experience. Dogs, cows and other animals go around places where people feel yin is heavy, and don't go directly through that place. Try to lead the cow there, close to the center with the heaviest yin. The cow seems to have been hit by something a few times, and a pair of backward feet jumped irregularly. The dog was led there, especially clever and obedient. His eyes are fixed on that position, and he dare not go near people's double retreat, which sometimes makes people walk inconvenient. The above are some special performances of some animals I have observed in places with heavy yin and qi, which are written here for reference.
