The Earth Element (土)

In BaZi, Earth is not a substance but a phase of change. Its qualities — stability, holding, mediation and trust — are used to describe how the stems and branches of that element behave and interact.

• Fire generates Earth (its resource).
• Earth generates Metal (its output).
• Earth controls Water (its wealth).
• Wood controls Earth (its officer).

Two further ideas appear in classical texts: an element can be "drained" by what it generates and "insulted" (反侮) by what it normally controls when that element is too strong. These describe imbalance rather than simple cycles.

The calculator counts Earth among the four visible stems and four branches, and lists hidden stems separately. Branches hiding Earth: 丑 Chou, 寅 Yin, 辰 Chen, 巳 Si, 午 Wu, 未 Wei, 申 Shen, 戌 Xu. A count is not a strength score — season and roots matter more than raw numbers.

Two Day Masters belong to Earth: 戊 Wu Yang Earth and 己 Ji Yin Earth. For them, the other elements map to Ten God families like this:

• Woodofficer (官杀)
• Fireresource (印)
• Earthcompanion (比劫)
• Metaloutput (食伤)
• Waterwealth (财)

Whether Earth is "too much" or "too little" is covered in Earth strong and Earth weak.

• 子子 ZiConfined (囚)
• 丑丑 ChouProsperous (旺)
• 寅寅 YinDead (死)
• 卯卯 MaoDead (死)
• 辰辰 ChenProsperous (旺)
• 巳巳 SiStrengthening (相)
• 午午 WuStrengthening (相)
• 未未 WeiProsperous (旺)
• 申申 ShenResting (休)
• 酉酉 YouResting (休)
• 戌戌 XuProsperous (旺)
• 亥亥 HaiConfined (囚)

Earth is prosperous in the transitional months between seasons, strengthening when the season element generates it, resting when it generates the season element, confined when it controls the season element and weakest ("dead") when the season element controls it.

• Earth + Wood: Wood controls Earth
• Earth + Fire: Fire generates Earth
• Earth + Earth: the same element
• Earth + Metal: Earth generates Metal
• Earth + Water: Earth controls Water

BaZi is a traditional cultural system. This page explains how the symbols are defined and read; it does not make scientific claims or predictions about your health, money or relationships.

The same element plays a different Ten God role depending on whose chart it is in. When you see Earth in a chart, first identify the Day Master, then read Earth through this table.

• 甲甲 Jia Yang Woodwealth (财) · Indirect Wealth (偏财) · Direct Wealth (正财)
• 乙乙 Yi Yin Woodwealth (财) · Direct Wealth (正财) · Indirect Wealth (偏财)
• 丙丙 Bing Yang Fireoutput (食伤) · Eating God (食神) · Hurting Officer (伤官)
• 丁丁 Ding Yin Fireoutput (食伤) · Hurting Officer (伤官) · Eating God (食神)
• 戊戊 Wu Yang Earthcompanion (比劫) · Friend (比肩) · Rob Wealth (劫财)
• 己己 Ji Yin Earthcompanion (比劫) · Rob Wealth (劫财) · Friend (比肩)
• 庚庚 Geng Yang Metalresource (印) · Indirect Resource (偏印) · Direct Resource (正印)
• 辛辛 Xin Yin Metalresource (印) · Direct Resource (正印) · Indirect Resource (偏印)
• 壬壬 Ren Yang Waterofficer (官杀) · Seven Killings (七杀) · Direct Officer (正官)
• 癸癸 Gui Yin Waterofficer (官杀) · Direct Officer (正官) · Seven Killings (七杀)

Visible Earth stems act directly; Earth hidden in branches acts as roots and background. A Earth frame (three harmony —, directional —) can make the element dominant even when few stems show it.

The fastest way to understand Earth element is to look at real charts rather than memorise rules. Enter a birth date, time and city in the BaZi Calculator, then locate where Earth element appears: in a visible stem, hidden inside a branch, in the current luck pillar or in this year's annual pillar. Note the position, because the year pillar is usually read as background and early life, the month pillar as environment and career setting, the day pillar as the self and close partner, and the hour pillar as later life and output.

• Compare two or three charts where Earth element is prominent and two where it is absent; write down what differs in the overall balance.
• Check the month branch first: seasonal strength changes how much any factor matters.
• Use the hidden-stems and Ten Gods tables in the calculator output instead of guessing.
• Treat single factors as clues, never as verdicts; classical texts always weigh the whole chart.

Different schools describe Earth element with slightly different emphasis. This site follows widely used conventions (solar-term months, true solar time optional, Zi hour setting configurable) and states them openly so you can compare results with a book or another calculator.

• "I lack Earth, so I should wear yellow." Colour remedies are folk practice, not part of chart calculation, and a missing element is not automatically a problem.
• "More of an element means it is strong." Season and roots usually outweigh counts.
• "Earth is my element because of my birth year." BaZi reads the Day Master (day stem), not the year.

Charts on this site use the published rule set: true solar time by default, the year changes at 立春 (Start of Spring), months change at the 12 节 solar terms and the day changes at 23:00. Example charts below are computed live by the same engine.
