Ji 己: Yin Earth, the field
A name you can say out loud: what the Ji image describes, where it sits among the five elements, and how it compares with the other nine stems. Nothing to fill in.
At a glance. Ji (己) is the Yin Earth stem, one of ten possible Day Masters. A Day Master is the stem of the day pillar, the reference point for describing a BaZi chart. The image describes tendencies, not outcomes, and it is not a reading of you. Last update: 2026-11-14.

What the Ji image describes
Ji is pictured as cultivated soil: receptive, quietly productive. Teachers use the image so the stem is easy to remember. People use it to talk about tendencies such as:
- Making other things grow: practical, patient support.
- Taking in what is given and turning it into something useful.
- Working in seasons rather than sprints.
The stretch in the image: boundaries. Not every seed has to be planted in the same field.
These are tendencies the image is used to talk about. They are not a description of you, and they do not predict anything. A full chart has eight characters; the Day Master is one of them.

Where Earth sits among the five elements
Choose a relation, or tap a circle on the wheel. Each one is a word BaZi uses to describe how the rest of a chart relates to the Day Master.
Solid: feeding cycle (生). Dashed: shaping cycle (克). Outlined: Earth.
Same element · Companions 比劫
Other Earth stems sit beside Ji as peers. In chart vocabulary this group is called Companions (比劫): people and pressures that are like you. It names a relationship, not a rival or a friend.
What it feeds · Output 食伤
Earth feeds Metal (土生金). In chart vocabulary, what the Day Master feeds is its Output (食伤): expression, making, saying. It describes a direction of energy, not talent or luck.
What it shapes · Wealth 财
Earth shapes Water (土克水). In chart vocabulary, what the Day Master shapes is called Wealth (财): what it works on and manages. Despite the name, it is not a money forecast.
What shapes it · Officer 官杀
Wood shapes Earth (木克土). In chart vocabulary, what shapes the Day Master is called Officer (官杀): rules, deadlines, responsibility. It describes structure, not punishment.
What feeds it · Resource 印
Fire feeds Earth (火生土). In chart vocabulary, what feeds the Day Master is called Resource (印): learning, support, rest. It is a kind of input, not a guarantee of help.
