丙 (Bing, Bǐng, “Yang Fire / Moon Wonder”) is one of the 9 Stems (三奇六儀) of Qi Men Dun Jia — one of the Three Wonders (三奇), classically the most-favourable group of stems. The Moon Wonder 丙 — yang fire, brightness, formal recognition, ceremony, and public-facing fame.
丙: classical reading and register
丙 (yang fire) is one of nine stems used in Qi Men Dun Jia chart construction. The Three Wonders (乙 / 丙 / 丁) are the most-favourable stems and represent classical 'wonder' registers (Sun, Moon, Star); the Six Yi (戊 / 己 / 庚 / 辛 / 壬 / 癸) are the 'instrument' stems that conceal the original Heavenly Stem 甲 during chart casting.
Formal ceremonies, fame-building, brand recognition, public-facing presentations, fire-element work. Despite being called 'Moon Wonder', 丙 represents yang fire — the bright, attention-drawing fire of public visibility.
Negative register
Public scandal, burnout, fire accidents when paired with vulnerable palaces, the 'too bright' register where visibility itself becomes the harm.
When to consult 丙
Read favourably for formal ceremonies, public-facing events, fame-building, brand-launch questions, and any consultation requiring sustained visibility.
Practical priorities
丙 as one of the Three Wonders carries the favourable register by default.
Read the stem alongside the gate / star / spirit / palace sharing its location. Stems modulate; the surrounding components determine activation.
The Moon Wonder 丙 — yang fire, brightness, formal recognition, ceremony, and public-facing fame. It is one of the Three Wonders (三奇), the most-favourable group of stems in classical QMDJ doctrine.
What's the difference between the Three Wonders and the Six Yi?
The Three Wonders (三奇: 乙 / 丙 / 丁) are the favourable stems classically associated with Sun / Moon / Star registers — wonders of celestial brilliance. The Six Yi (六儀: 戊 / 己 / 庚 / 辛 / 壬 / 癸) are the instrument stems used during chart casting; they conceal the six 甲 leader stems (甲子 / 甲戌 / 甲申 / 甲午 / 甲辰 / 甲寅) under their respective 戊 / 己 / 庚 / 辛 / 壬 / 癸 covers. The original 甲 is never directly visible in the chart — it operates through its concealing yi.
Should I look for 丙 specifically in my consultation?
Read favourably for formal ceremonies, public-facing events, fame-building, brand-launch questions, and any consultation requiring sustained visibility.
