Xin 辛: Yin Metal, the jewel
A name you can say out loud: what the Xin 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. Xin (辛) is the Yin Metal 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 Xin image describes
Xin is pictured as jewellery or refined metal: precise, sensitive to quality. Teachers use the image so the stem is easy to remember. People use it to talk about tendencies such as:
- Noticing quality and detail other people miss.
- Refining: making a thing better rather than bigger.
- Valuing being seen accurately.
The stretch in the image: being seen before the polishing is finished.
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 Metal 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: Metal.
Same element · Companions 比劫
Other Metal stems sit beside Xin 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
Metal feeds Water (金生水). 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
Metal shapes Wood (金克木). 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
Fire shapes Metal (火克金). 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
Earth feeds Metal (土生金). 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.
