Fire 火 (huo)

Fire is the element of visibility, the phase where something that has grown becomes something other people can see.

火 is summer, midday, and expansion outward. Its two stems are 丙 (bing), the sun, and 丁 (ding), the lamp; its two branches are 巳 (si) the snake and 午 (wu) the horse. The tradition also links it with warmth in the ordinary human sense, presence and recognition.

In the generating cycle Wood feeds Fire and Fire feeds Earth, since what burns becomes ash and ground. In the controlling cycle Fire acts on Metal, the image of the forge. Both relationships matter, and neither one is a reward or a punishment.

A Fire day on this page is a day whose stem is 丙 or 丁. Fire days often read as quick, which the tradition names as tempo, a description of pace rather than a claim about how your day will go.
