What Is Fire at the Foot of the Mountain (山下火) in BaZi?
Identify the 丙申–丁酉 Mountain-Foot Fire pair, its fading-light and named support conditions, and its limits for personality, health, and fate claims.
Overview
Fire at the Foot of the Mountain is the fire-class Nayin assigned to 丙申 and 丁酉. Classical sources place fire at its sickness and death stages in 申酉 and use a low, fading, or firefly-like light as the image; wood, water, wind, and other fires are then judged by exact pair and context, not by a universal slogan.

Mountain-Foot Fire belongs to 丙申 and 丁酉
The fixed sixty-Jiazi table assigns this Nayin only to complete 丙申 and 丁酉 pillars. A Bing or Ding stem, a Shen or You branch, a mountain location, sunset, or characters taken from different pillars do not create the classification.
丙 and 丁 remain fire stems; 申 and 酉 remain metal branches with their ordinary hidden-stem rules. The fire Nayin is a pair-level historical label and does not convert either branch into ordinary fire.
- Match one complete stem-branch pair.
- Preserve the original phase, branch, and hidden-stem data.
The source describes diminished light, not a fixed weakness
Classical explanations place fire at sickness in 申 and death in 酉, as summer heat fades and the sun moves west. San Ming Tong Hui also uses small lights among grass and water, so later readings distinguish a firefly-like glow from a larger fire supported by mountain and wood.
Named wood, water, wind, earth, and fire combinations determine whether the image is sustained, reflected, dispersed, or excessive. The passage cannot be reduced to “wood always helps,” “water always harms,” or “this Nayin is weak.”
- State which classical image and exact supporting pair is being used.
- Treat wind, water, and wood as conditional rather than automatic.
The Nayin image does not set ordinary fire strength
OpenFate deterministically maps 丙申 and 丁酉 to Fire at the Foot of the Mountain. Compatibility keeps the label as non-scoring auxiliary evidence and does not let it override direct pillar relations, chart structure, or favorable-element analysis.
Actual fire strength and function depend on Month Command, roots, hidden and exposed stems, support, control, combinations, clashes, dryness, moisture, and timing. The low-light image is not a chart-wide verdict.
- Keep the table lookup outside the main score.
- Use complete chart evidence to judge actual fire.
A small light does not define ability or destiny
Mountain-Foot Fire does not prove low energy, weak eyesight, hidden talent, modest fame, night work, attraction, danger, accident risk, or a short life. A historical light image is neither a diagnosis nor a biography.
Health, work, travel, fire safety, and relationship decisions require current evidence and qualified support. Do not use this Nayin to rank a person, prescribe an occupation, or predict harm.
- Exclude health, ability, reputation, and lifespan claims.
- Keep consequential decisions grounded in real evidence.
