The “element” (or phase) huo 火, Fire, is associated with the idea of summer, although it does not represent that cosmic season concretely.

If Wood is the young yang principle, Fire is the already mature yang, hence more relaxed and communicative on the human plane.

However, Fire can manifest through two aspects, the yang aspect and the yin aspect, although both stem from the same raw material.

Yang Fire (bing 丙) is symbolized by the Sun, with all its capacity to shine and warm. Its power is obvious, as is its visibility. It makes a difference whenever it enters the scene.

In contrast, Yin Fire (ding 丁), symbolized by a Flame or by Moonlight, is the same brightness and emotional communication capacity but in a more intimate context.

The two manifestations (and their respective celestial stems) of the Fire “element” become more evident when they correspond to the Day Master (or “Personal Element”) of the person to whom the Bazi birth chart refers.
