Ding Day Master (丁 Yin Fire): the lamp and the candle

At a glance. Ding (丁) is the Yin Fire 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 Ding image describes

Ding is pictured as a candle or lamp: focused light in a small space. Teachers use the image so the stem is easy to remember. People use it to talk about tendencies such as:

Close attention: lighting one page, one person, one problem.
Care that is quiet rather than loud.
Insight that works best when the room is dark.

The stretch in the image: guarding the flame from wind, meaning its own energy.

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.
