Na Yin Shan Xia Huo

Fire Below the Mountain is the Na Yin name assigned to the 丙申 and 丁酉 pillars in the sixty-pillar cycle. The Chinese term is 山下火. Treat it as a symbolic layer after the chart's stems, branches, ten gods, season, and luck cycles are known.

How to identify it

If a pillar is 丙申 or 丁酉, its Na Yin is Fire Below the Mountain. The lookup is fixed: both pillars share the same Na Yin name, while their chart positions and hidden stems still have to be read separately.

Reading emphasis

Use Fire Below the Mountain as a secondary image for how a pillar expresses itself. In the year pillar it may color background and early conditions; in the month pillar, social role and work structure; in the day or hour pillar, personal style, execution, and later outcomes.

For timing work, a year, month, or luck cycle carrying 丙申 or 丁酉 may activate this symbolic tone. Do not use the Na Yin name by itself to call an event good or bad; the main judgment still comes from the arriving ten god, branch interactions, and the natal chart's needs.
