Fire in the Heavens (tiān shàng huǒ) is the NaYin of WuWu and JiWei, taking its image from the midday sun at the peak of summer. Wu and Wei mark the height of yang qi, and the sun shines through its own sustained radiance across all things; its central themes are strength, outward energy, clarity and broad influence.

The classical imagery

The San Ming Tong Hui on the fire of WuWu and JiWei:

“The qi passes the palace of Yang, doubled Li meeting Li, blazing spirits crossing their light — hence, Fire in the Heavens.”

— Wan Minying (Ming dynasty), San Ming Tong Hui, vol. 1, “On NaYin Imagery”

"The qi passes the palace of Yang; doubled Li meets itself" — Li is the trigram of fire and of the sun, and doubled Li is one brightness laid over another: the Yijing Li hexagram's "brightness twice arising," light stacked upon light, blazing spirits crossing their rays.

Traditional reading of the temperament

Tradition regards the Fire in the Heavens life as outward in energy and open of heart: wherever such people go, the light goes with them; every feeling shows on the face, likes and dislikes laid out in plain view — they keep no guard up, and have little patience for those who do. Their infectiousness is native: the mood of a whole room often takes its key from this one person. They do best working in broad, sweeping strokes; anything furtive runs against the grain of their nature.

On the cautionary side, the classics make two points. First, "the sun at its height begins to slant" — the moment of greatest brilliance is precisely when the westward lean begins, so this life should stay watchful at its peak. Second, an unshaded sun both illuminates and scorches; overflowing warmth can burn the very people it means to cheer, and there is something to learn from clouds — leaving a little shade for oneself and for others. On men and women, the old view gives both a fierce nature and high standing, the female chart a dazzling presence — under this much sun, those old shadows run short; no need to dwell on them.

Relations with other NaYin

In folk NaYin lore, wherever Fire in the Heavens shines the woods flourish — Great Forest Wood and Pine and Cypress Wood take its warmth kindly; meeting Gold in the Sand brings the caution of "fierce sun parching the gold"; and its finest meeting is with Sky-River Water, of which the old books say "sun and rain share one sky, and their crossing completes itself as a rainbow." There is nothing new under the sun, and these rhymes have been drying in it for a thousand years — once aired, pick the few lines that fit and leave the rest.

FAQ

Jay Chou was born in 1979 — why is he a WuWu Fire in the Heavens rather than a JiWei one?
January 18, 1979 falls before that year's LiChun (February 4), so by the LiChun boundary his year pillar belongs to the previous year, WuWu — whose NaYin happens to be Fire in the Heavens as well. It is the textbook case of the LiChun cutoff: the calendar year has changed while the GanZhi year has not. Born in January 1980, he would count under JiWei rather than GengShen.
Was 1978 a Fire in the Heavens year?
Yes — those born in 1978 (WuWu) have Fire in the Heavens as the NaYin of the year pillar. The boundary is LiChun: birth before LiChun on February 4, 1978 belongs to the previous year DingSi, whose NaYin is Earth in the Sand.
Is a Fire in the Heavens life too “scorching”?
A blazing sun overhead — dryness is built into the image, and the old books do often advise this life to temper itself with Water and leave a margin in word and deed. But the other face of scorching is candor: under full sunlight there are no shadows, and openness is exactly what this life is praised for most. How heat and clarity balance out depends on the whole chart's proportion of Water to Fire.
