Ren 壬: Yang Water, the river and the sea
A name you can say out loud: what the Ren 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. Ren (壬) is the Yang Water 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 Ren image describes
Ren is pictured as a great river or the ocean: moving, hard to contain. Teachers use the image so the stem is easy to remember. People use it to talk about tendencies such as:
- Momentum: once moving, it keeps going.
- A wide view, carrying many things at once.
- Going around obstacles rather than through them.
The stretch in the image: banks. A river with banks gets somewhere; without them it floods.
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 Water 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: Water.
Same element · Companions 比劫
Other Water stems sit beside Ren 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
Water feeds Wood (水生木). 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
Water shapes Fire (水克火). 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
Earth shapes Water (土克水). 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
Metal feeds Water (金生水). 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.
