Jijanggan: The Hidden Stems Inside Every Branch of Your Saju

2026-07-10 · computed with the solar-term engine (the Method)

The bottom row of a saju (사주) chart looks simple: four branches, four animals, four plain characters. It is the most deceptive row on the chart. Every branch is a container, and inside each one sit two or three heavenly stems, folded away out of sight. These are the jijanggan (지장간), the hidden stems, and a reading that ignores them is reading only half the chart. The visible characters are the storefront. The hidden stems are the inventory in the back room, and that is often where the wealth, the spouse, and the authority a life turns on are actually kept.

Before this makes sense you want the twelve branches and the ten stems as separate ideas. This article is about how the first quietly contain the second.

Why Branches Hold Stems At All

A branch is a season made concrete, and a season is never one pure thing. Early spring still carries the cold of winter; late summer already holds the dryness of autumn turning. So each branch stores a small committee of stems that reflect the transition it sits in. The Tiger branch, first month of spring, holds Wood at full strength but keeps a residue of the Fire and Earth that live nearby on the wheel. Nothing in a saju chart is a solid block; everything is a blend, and the hidden stems are how the tradition writes the blend down.

The Three Layers Inside a Branch

The stems inside a branch are not equal. They sit in order of dominance, and readers name three roles.

The yeogi (여기), the lingering energy, is the leftover from the previous branch, weakest of the three. The junggi (중기), the middle energy, is often the stem that connects the branch into a three-way alliance, and it can surge in importance when that alliance forms. The jeonggi (정기), the main energy, is the branch's true element, the one that matches its season and carries the most weight. When a reader says a branch is Wood or Water, it is the jeonggi they mean, but the other two are still in the room.

Where a Chart's Real Money Lives

Here is why this matters in practice. Suppose your visible eight characters contain no wealth star at all. A beginner declares you poor in wealth and moves on. A reader checks the hidden stems and finds your wealth element tucked inside a branch, out of sight but present, waiting for the right year to draw it out. The same is true for the authority star and for the spouse a chart promises. Some of the most important characters in a life never appear on the surface at all. They live in the back room, and only the hidden stems reveal them.

This is also why two charts with identical visible characters are not identical. The branches they sit on carry different hidden inventories, and those inventories change what the ten gods reading actually adds up to.

The Day Branch and the Spouse

One placement deserves special attention. The hidden stem inside your day branch, the character sitting directly beneath your day master, is the seat of the spouse palace. Because it is hidden, the qualities of a future partner are often written here rather than out in the open, which is part of why compatibility work leans so heavily on this one branch. A reader doing gunghap will open the day branch of both people and read what is stored inside before saying anything about the match.

Hidden Stems and the Passing Years

Hidden stems are not permanently sealed. A clash from a passing year or a ten-year luck cycle can crack a branch open and release what was stored, which is one mechanism behind years that seem to deliver something out of nowhere: a sudden windfall, an unexpected relationship, a promotion that had no visible cause. The cause was there all along, folded inside a branch, and the year simply opened the container. This is also why storehouse branches reward close reading, because what they release depends entirely on what they hold.

Reading Your Own Back Room

You cannot see hidden stems on a plain printed chart, which is exactly why a real engine matters. Open your four branches and ask what each one stores, not just what it shows. Look especially at the day branch for the spouse, and at any branch holding a wealth or authority stem your surface characters seem to lack. A chart that looks empty of something on top is very often holding it underneath.

Cast your free chart and let the branches open. The characters on the surface are only the introduction. The hidden stems are where the tradition keeps most of what it knows about a life.
