Geng Yin (庚寅) Day Pillar

The Day Master Geng (庚) has the energy of raw iron, being quick in decision-making and loyal. The Day Branch Yin (寅) is dynamic and enterprising. Although the Day Master controls the Day Branch and takes the initiative, care must be taken not to suppress the spouse palace.

You have a strong tendency to lead your spouse, so you need the consideration to wait for them. The Day Branch Yin, as the spouse palace, implies a spouse who is dynamic and enterprising.

In the Twelve Stages of Life, it corresponds to Extinction (絶), meaning frequent transitions of cutting off and starting anew, leading to many changes.

There are times when your drive weakens, so encourage yourself.

Geng Yin (Korean: Gyeongin) is an iron axe entering a tiger's forest, energized by breaking new ground and opening fresh territory. The branch's main qi is Indirect Wealth (偏財) Jia wood, giving a knack for moving money at scale through big deals, business expansion, sales or distribution. Hidden Bing fire as Seven Killings (偏官) marks a temperament forged by competition and pressure, and Indirect Resource (偏印) Wu earth adds technical expertise. Construction, manufacturing, startups, sports and machinery are also good fits. The Cutoff (絶) stage can bring income that stops and restarts, so rather than spending big in strong years, keeping a separate buffer for the next transition is the steadier path.

Geng Yin is a straight-ahead type who approaches without hesitation once interest sparks. With Indirect Wealth (偏財) as the branch's main qi, this person has a wide social range, looks after people generously and tends to express love in visible ways, such as plans, surprises or gifts. Friends know them as the loyal fixer, yet the decisiveness of iron often reaches a conclusion before the other person's feelings have been fully heard. Add the heat of hidden Seven Killings (偏官) Bing fire and a disagreement can escalate in moments. A habit of asking 'What do you think?' once before giving a verdict softens the texture of this pillar's relationships considerably.

The way for Geng Yin to use this pillar can be found in how an axe turns trees into timber. Facing the broad forest of Indirect Wealth (偏財), the habit of drawing a blueprint before cutting, deciding what to build rather than felling everything in sight, is what separates good results from scattered ones. Hidden Wu earth, Indirect Resource (偏印), is the root that nourishes metal, so steady investment in professional credentials or technical study builds the strength to hold firm through the swings of the Cutoff (絶) stage. To resemble its napeum, Pine and Cypress Wood (松柏木), green in every season, persistence matters more than speed: a short daily routine of exercise or study serves this pillar better than bursts.

The decisive energy of solemn execution (肅殺). Strong sense of loyalty and justice, with clear-cut boundaries.
