Yang Fire Day Master (丙火) in BaZi

The ten gods are not ten things — they are five relations, each of which comes in two polarities, and the relation is always measured from the day master. With 丙 as the reference the five relations resolve as follows: 火 itself is the Peer, Wood generates 火 and is the Resource, Earth is what 火 produces and is the Output, Metal is what 火 controls and is the Wealth, and Water is what controls 火 and is the Officer.

The table below is produced by the engine from that rule alone — the element relation, multiplied by whether the two stems share a polarity. Nothing in it is memorised and nothing in it is interpreted. This is the reason a chart can be re-read by anyone: change the day master and all ten names change at once, in a way that is checkable rather than a matter of opinion. On the chart in the worked example below, 丙 is the day stem itself, so the four visible stems around it each carry one of these names.

A chart is not read by counting elements — it is read by what each element does to the day master. Wood (甲 乙) generates 火, so it is the Resource: what supplies 丙 without being asked. 丙 丁 is the Peer. Earth (戊 己) is what 火 produces, so it is the Output: energy that leaves as work, expression or craft. Metal (庚 辛) is what 火 controls, so it is the Wealth. Water (壬 癸) is what controls 火, so it is the Officer — the element that acts on 丙 and therefore carries the chart's pressure.

Five relations doubled by polarity gives the ten gods, and that is the whole structure. What it does not give you is a verdict on whether 丙 has enough support, because that judgement depends on how much you weight the month of birth, whether hidden stems count fully, and whether rootedness outranks raw count — and three competent practitioners can disagree. So we print the counts and the support/drain split, and leave the weighing to the reading rather than hiding a weighting model inside a score.

丙 appears inside two branches: 巳, where it is the primary hidden stem, and 寅, where it is a secondary one. So yang fire can be present in a chart that never shows a 丙 on the surface — worth knowing, because the branch it hides in also carries wood, which is what produces it.

This matters more than it sounds. Four of the eight characters in a chart are branches, and each branch conceals between one and three stems, so a chart can hold 火 energy in a form that never appears on the surface. The list below is generated from the same fixed hidden-stem table the calculator uses — you can check it branch by branch.

The sun image gets read as "extrovert", which is too narrow and too personal. 丙 is a statement about visibility, not about temperament: it describes a chart whose energies are read in public terms. A 丙 day master can be withdrawn — what the stem actually predicts is that things tend to become visible, whether or not the person wants them to.
