Yang Fire (the visible Heavenly Stem 丙) above, with Yin Water (the dominant hidden energy inside the Rat Earthly Branch 子) below. Classically known as 丙子 (Bing Zi), the 13th of sixty pillars.
The Rat branch's surface label is sometimes given as Yang Water in popular references, but its dominant hidden energy (本气, běn qì) is Yin Water. Classical pillar interpretation reads the dominant hidden energy as the truer signature. Read our methodology →
The Lighthouse
Public flame above unseen current.
In plain terms: "Lighthouse" is a personality type in Chinese astrology, worked out from the day you were born — public flame above unseen current.. (Here, a "pillar" simply means one of the four energy snapshots that make up your birth chart.)
Personality of the Lighthouse
Bing Zi pairs Yang Fire with Yin Water in the Rat branch, the image of a lighthouse projecting useful light across moving water. The Yang Fire stem brings public warmth and orientational clarity; the Yin Water Rat branch contributes perceptive intelligence and quiet timing. People born here tend to be the ones others find when they are lost. Their gift is not raw enthusiasm but oriented enthusiasm that shows direction without forcing it. The challenge is the inner lamp depends on a steady inner reserve, and crowded environments can drain that reserve faster than the pillar realizes.
Hidden Energies Inside the Branch
The branch animal carries the following hidden energies within it. The first listed is the dominant signature (本气), which is what defines this pillar's energetic identity. The others are secondary supporting energies that surface in specific timing and life conditions.

How This Pillar Fits the Sixty Year Cycle
The sexagenary cycle tracks sixty unique stem and branch combinations that repeat every sixty years. The Lighthouse occupies position 13 of 60, sitting between the pillars before and after it within the great elemental rhythm. Each cycle, the same pillar returns with the same energetic signature, which is why birth years separated by exactly sixty years share the natal pillar described on this page.
