Feng shui emphasizes "calling the form and drinking the image," which, simply put, is about interpreting the feng shui environment. "Calling the form and drinking the image" is a core concept in feng shui (primarily the Form School) and physiognomy, and can be understood as "naming is summoning" or "locking in energy with a name." Things in nature or the environment that are not inherently alive, but whose shape resembles a certain animal or object, can be interpreted by a feng shui master through language (such as calling it "Azure Dragon" or "Lion"), thus being treated as real animals to influence good or bad fortune. For example, seeing a mountain peak shaped like a knife, it is directly called "Sickle Sha," possessing the sharpness and destructive power of a knife. In feng shui, winding mountain ranges are called "Dragons," and rounded hills are called "Pearls" or "Drums," a practice called "calling the form." Seeing a stone resembling a toad, it is directly called "Golden Toad," implying the spitting out of wealth, a practice called "drinking the image."
