General Knowledge

Bing Fire is the yang fire of the Ten Stems — the sun, not a candle. This guide explores Bing's nature, its critical relationship with壬water (the river that reflects the sun), monthly seasonal adjustments, and how Bing Fire Day Masters navigate career, leadership, and relationships through radiance rather than force.

Ding Fire is the yin fire — the lamp, the candle, the star. Unlike the sun (Bing), Ding burns selectively, precisely, and for as long as it has fuel. This guide explains Ding's need for Jia Wood as fuel, its relationship with Geng Metal, and how Ding Day Masters achieve through focus rather than radiance.

Jia Wood represents the giant tree, the beam, the leader. This guide covers Jia's yin-yang nature, the critical distinction between living and dead wood, monthly seasonal adjustments, and how Jia Wood shapes personality, career, and destiny in Bazi.

The Five Stem Combinations (天干五合) are the merging rules of the Ten Heavenly Stems: Jia-Ji into Earth, Yi-Geng into Metal, Bing-Xin into Water, Ding-Ren into Wood, Wu-Gui into Fire. This guide traces their origin in the River Chart (河图), explains the four conditions for successful transformation, and covers stem-self combinations (干支自合) as practical extensions.

Wu Earth is the yang earth — the mountain, the city wall, the dam. Unlike Ji Earth (the field), Wu Earth's value is structural: it carries weight and blocks water. This guide explains Wu's need for Jia Wood to break its crust and壬water to justify its existence, plus the full seasonal adjustment map.

Yi Wood is the flexible yin counterpart to Jia — the vine, the grass, the crop. This guide explains Yi's essential nature, its symbiotic relationship with Jia, the living-dead distinction for Yi, and how Yi people navigate career, relationships, and challenges through flexibility rather than force.
