Home / BaZi BaZi Database 101 entries. The ten day masters and the ten gods, as a reference. Each entry gives the definition, the position in the system, and how the term is used in the traditional sources.
BaZi takes its name from the four pillars — year, month, day and hour — each written as a heavenly stem paired with an earthly branch. Those eight characters are the whole input. Everything else, including the ten gods, is derived from relationships among them rather than looked up anywhere, which is why the terminology has to be learned before a chart becomes readable at all.
The day master is the stem of the day pillar, and it stands in for the person whose chart this is. The other seven characters are then described by how they relate to that one stem, and those relationships are the ten gods: same element is Friend or Rob Wealth, what the day master produces is Eating God or Hurting Officer, what restrains it is Direct Officer or Seven Killings, and so on through Wealth and Resource. Someone comfortable with those names can read a chart's shape in a few seconds.
This library splits down those two lines — fifty entries on the day masters, covering what each stem is like at the centre of a chart, and fifty-one on the ten gods, covering what each relationship contributes wherever it shows up. They are designed to be read against each other: a day master entry tells you what Jia Wood is inclined toward, and the ten gods entries tell you what it means that Wealth sits in the month pillar of that same chart.
None of this becomes concrete without a chart. The BaZi calculator produces the four pillars, the ten gods and the current luck pillar from a birth date and time, free and without an account. Use it alongside these entries — a definition understood abstractly tends to evaporate within a day, while the same definition attached to one's own chart tends to stay.
This is a reference for the vocabulary of BaZi. It is not a chart reading — that requires the full chart, and no entry here should be taken as guidance about what to do.
Day Master · 50 Jia 甲 — Yang Wood Jia is the first heavenly stem and the yang form of Wood — traditionally described as the standing tree. Jia — Personality Traditional descriptions of Jia as day master use the imagery of the tall tree — growth, directness, and resistance to being moved.

Ten Gods · 51 Bi Jian 比肩 — Parallel Self Bi Jian is the ten god representing the same element as the day master in the same polarity — the parallel self. Bi Jian in a Chart Bi Jian appears wherever a stem shares the day master's element and polarity — in any of the four pillars. Bi Jian in Career In the traditional reading, Bi Jian relates to work done alongside equals and to independent rather than subordinate positions. Bi Jian and Wealth Because Bi Jian shares the day master's element, traditional readings associate it with resources divided among equals. Bi Jian in Relationships Traditional readings associate Bi Jian with equals — siblings and peers — rather than with the partner stars. Jie Cai 劫财 — Robbing Wealth Jie Cai is the same element as the day master in the opposite polarity — named for its relationship to the wealth star. Jie Cai in a Chart Jie Cai appears wherever a stem shares the day master's element with opposite polarity. Jie Cai in Career Traditional readings associate Jie Cai with competitive settings and with work where resources are contested.

Jie Cai in Relationships Traditional readings place Jie Cai among the sibling and peer gods rather than among the partner stars. Shi Shen 食神 — Food God Shi Shen is the element the day master generates, in the same polarity — conventionally read as expression and output. Shi Shen in a Chart Shi Shen appears wherever a stem is the element the day master generates, in matching polarity. Shi Shen in Career Traditional readings associate Shi Shen with work that produces something — craft, teaching, and expressive trades. Shi Shen and Wealth In the traditional scheme, what the day master generates can in turn generate the wealth element — a chain rather than a direct link. Shi Shen in Relationships For a female chart in the traditional system, the gods the day master generates are the children stars. Shang Guan 伤官 — Hurting Officer Shang Guan is the element the day master generates in the opposite polarity — named for its effect on the authority star. Shang Guan in a Chart Shang Guan appears wherever a stem is the element the day master generates, in opposite polarity. Shang Guan in Career Traditional readings associate Shang Guan with work involving critique, performance, or independence from established structure. Shang Guan and Wealth Like Shi Shen, Shang Guan connects to wealth through the generating chain rather than directly. Shang Guan in Relationships Alongside Shi Shen, Shang Guan fills the children star role in female charts in the traditional assignment. Zheng Cai 正财 — Direct Wealth Zheng Cai is the element the day master overcomes, in opposite polarity — conventionally the direct wealth star. Zheng Cai in a Chart Zheng Cai appears wherever a stem is the element the day master overcomes, in opposite polarity. Zheng Cai in Career Traditional readings associate Zheng Cai with regular income from sustained work rather than with irregular gain. Zheng Cai and Wealth Zheng Cai is the wealth star itself — the term names a position in the chart rather than an amount of money. Zheng Cai in Relationships In the traditional assignment, Zheng Cai represents the wife in a male chart — the convention is explicit in the classical sources. Pian Cai 偏财 — Indirect Wealth Pian Cai is the element the day master overcomes, in the same polarity — the indirect wealth star. Pian Cai in a Chart Pian Cai appears wherever a stem is the element the day master overcomes, in matching polarity. Pian Cai in Career Traditional readings associate Pian Cai with income from ventures, commissions and irregular sources. Pian Cai and Wealth As with Zheng Cai, Pian Cai names a relationship rather than an outcome, and the traditional reading weighs it with the rest of the chart.

Zheng Guan 正官 — Direct Officer Zheng Guan is the element that overcomes the day master, in opposite polarity — the direct authority star. Zheng Guan in a Chart Zheng Guan appears wherever a stem overcomes the day master in the contrasting polarity. Zheng Guan in Career Traditional readings associate Zheng Guan with positions of recognised authority and with working inside a structure. Zheng Guan and Wealth In the generating chain, the authority element generates the resource element, which supports the day master — an indirect connection to wealth. Zheng Guan in Relationships In the traditional assignment, Zheng Guan represents the husband in a female chart — the counterpart to the wealth star's role in male charts. Qi Sha 七杀 — Seven Killings Qi Sha is the element that overcomes the day master, in the same polarity — the indirect or severe authority star.

Qi Sha in Career Traditional readings associate Qi Sha with competitive or high-pressure positions and with authority won rather than granted. Qi Sha and Wealth Qi Sha connects to wealth through the same generating chains as Zheng Guan, and is not itself a wealth star. Qi Sha in Relationships In female charts the traditional assignment places Qi Sha alongside Zheng Guan in the partner-star group, distinguished by polarity. Zheng Yin 正印 — Direct Seal Zheng Yin is the element that generates the day master, in opposite polarity — the direct resource star. Zheng Yin in a Chart Zheng Yin appears wherever a stem generates the day master in the contrasting polarity.
