What Is Bazi? Four Pillars of Destiny Explained
Why can two Bazi calculators show different pillars?
Compare year and month boundaries, local civil versus solar time, time-zone handling and day rollover conventions. This site changes the year pillar at the exact Li Chun moment and the month pillar at the exact Jie moment, so a calculator that uses Lunar New Year or date-level boundaries can differ near a transition. Check the calculation method before interpreting the difference.
Is the Day Master the same as my zodiac animal?
No. The Day Master is the Heavenly Stem of the day pillar. A birth-year zodiac animal comes from the year branch. In the illustrative day pillar Jia Zi, Jia is the Yang Wood Day Master and Zi is the Rat branch; the year animal cannot be inferred from that day pillar alone.
The Five Elements (Wu Xing)
What are the Five Elements in Chinese metaphysics?
The Five Elements (Wu Xing, 五行) are Wood (木), Fire (火), Earth (土), Metal (金), and Water (水). Unlike the Western four-element model, Wu Xing describes five phases of cyclical energy rather than static substances. Each element has associated seasons, organs, directions, emotions, and qualities used across Bazi, Feng Shui, and Traditional Chinese Medicine.
What is the difference between the generating and controlling cycles?
The generating cycle (相生, xiāng shēng) is the nourishing sequence: Wood feeds Fire, Fire produces Earth ash, Earth yields Metal ore, Metal collects Water, Water nourishes Wood. The controlling cycle (相克, xiāng kè) is the restraining sequence: Wood parts Earth, Earth dams Water, Water extinguishes Fire, Fire melts Metal, Metal chops Wood. Both cycles operate simultaneously in every Bazi chart.
How do I find my element in Bazi?
Your primary element in Bazi is determined by your Day Master — the Heavenly Stem of the day pillar in your Four Pillars chart. For example, a Jiǎ (甲) or Yǐ (乙) Day Master is a Wood person. The full chart will also contain other stems and branches that add, drain, or restrain that element, so the Day Master is a starting point, not the complete picture.
What do Wood, Fire, Earth, Metal, and Water represent in Bazi?
Wood represents growth, vision, and expansion — linked to spring and the liver. Fire represents expression, clarity, and warmth — linked to summer and the heart. Earth represents stability, transition, and nurturing — linked to the seasonal change between seasons and the stomach. Metal represents structure, precision, and contraction — linked to autumn and the lungs. Water represents wisdom, adaptability, and depth — linked to winter and the kidneys.
How is Wu Xing different from Western four elements?
The Western model (fire, water, earth, air) describes static substances and temperament archetypes rooted in ancient Greek philosophy. Wu Xing describes dynamic phases of change in a cyclical relationship — each element transforms into the next through the generating cycle. Wu Xing is also embedded in time (each element governs specific hours, days, months, and years) and is used as a practical calculation system rather than a symbolic framework alone.
Can I balance my Five Elements through lifestyle choices?
Classical Bazi does not prescribe specific remedies for element imbalance in the same way modern wellness culture does. The primary tool is awareness: knowing which elements are weak or excessive in your chart helps you interpret the luck cycles and annual influences that supply or drain those elements over time. Some practitioners do suggest colour, direction, or diet associations derived from Five Element theory, but these are supplementary interpretations rather than core classical doctrine.
The 10 Heavenly Stems (Tian Gan) and the Day Master
What are the 10 Heavenly Stems in Bazi?
The 10 Heavenly Stems (天干 Tian Gan) are Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, and Gui. Each stem is the yang or yin expression of one of the Five Elements: Wood, Fire, Earth, Metal, and Water. In a Bazi chart, the stems occupy the top row of the four pillars and represent visible, expressed energy.
What is the Day Master in Bazi?
The Day Master is the Heavenly Stem of the day pillar in your Bazi chart. It represents the self — the reference point from which every other stem and branch is interpreted. All Ten God relationships are calculated relative to the Day Master's element, making it the single most important character in the chart.
What is the difference between yang and yin stems?
Yang stems (Jia, Bing, Wu, Geng, Ren) represent outward, expanding, and direct expressions of their element. Yin stems (Yi, Ding, Ji, Xin, Gui) represent inward, subtle, and adaptive expressions. For example, Jia Wood is like a tall tree — upright and visible — while Yi Wood is like a vine that bends and adapts to its environment.
How do Heavenly Stem combinations work?
Adjacent yang and yin stems of complementary elements can combine and transform into a new element. For example, Jia (Yang Wood) and Ji (Yin Earth) combine to produce Earth energy. These combinations are conditional — they require seasonal support from the month branch to fully transform, and a clashing stem can block the combination.
Can two people have the same Day Master but different charts?
Yes. The Day Master is determined by the day of birth, but the remaining seven characters — the year, month, and hour stems and branches — create an entirely different surrounding context. Two Jia Wood Day Masters born in different months, hours, or years will have different elemental balances, Ten God patterns, and luck cycle timings.
Which stem represents me in Bazi?
Your Day Master stem — the top character of your day pillar — represents you. You can identify it by entering your birth date and time into a Bazi calculator. The stem's element and polarity (yang or yin) describe the core quality of how you express yourself and engage with the world.
12 Earthly Branches (Di Zhi)
What are the 12 Earthly Branches in Bazi?
The 12 Earthly Branches (地支 dì zhī) are Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai. Each branch carries an element, a yin-yang polarity, a season, a two-hour time period, and one or more hidden stems inside it. They form the lower row of all four pillars in a Bazi chart.
What are hidden stems and why do they matter?
Hidden stems (藏干 cáng gān) are the Heavenly Stems concealed inside each Earthly Branch. For example, the branch Yin hides Jia Wood (main), Bing Fire, and Wu Earth. These hidden stems carry additional elemental energy that can activate Ten God relationships not visible in the surface layer of the chart, making them critical for accurate chart reading.
What is a branch clash (六冲) in Bazi?
A branch clash (六冲 liù chōng) occurs when two opposing branches appear in the same chart or luck cycle. The six clash pairs are Zi-Wu, Chou-Wei, Yin-Shen, Mao-You, Chen-Xu, and Si-Hai. Clashes indicate tension, disruption, or forced change in the life area governed by the affected pillar. They are not always negative — clashes can break stagnation and trigger necessary transitions.
How do branch combinations (六合) differ from clashes?
Branch combinations (六合 liù hé) pair branches that attract and potentially transform each other: Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, Si-Shen, and Wu-Wei. Unlike clashes, combinations suggest merging or blending energy. When conditions are met — seasonal support and no blocking clash — a combination can transform both branches into a new dominant element, altering the chart's elemental balance.
What is the difference between a branch and a zodiac animal?
Each of the 12 Earthly Branches corresponds to one zodiac animal: Zi is Rat, Chou is Ox, Yin is Tiger, and so on. The animal is the popular name for the branch, but in Bazi analysis the branch is defined by its element, hidden stems, season, and relationships — not by personality traits associated with the zodiac. The animal label is a mnemonic; the elemental analysis is what matters in chart reading.
Why does the month branch have the most weight in a Bazi chart?
The month branch sets the season, which determines whether any given element is in season (strong) or out of season (weak). A Day Master's strength is assessed primarily against the month branch. Classical texts like Yuan Hai Zi Ping (渊海子平) consistently read the month branch first because it provides the environmental context that makes all other branch and stem readings meaningful.
What does Di Zhi (地支) mean in English?
Di Zhi (地支) translates as "Earthly Branches" — di means earth and zhi means branch. The twelve Di Zhi are the terrestrial half of the Chinese sexagenary cycle, paired with the ten Tian Gan (天干, Heavenly Stems). "Kuar-di Zhi" is an alternate romanization sometimes seen in search; it refers to the same 12 Earthly Branches.
What is the order of the 12 Earthly Branches?
The fixed order is Zi (子), Chou (丑), Yin (寅), Mao (卯), Chen (辰), Si (巳), Wu (午), Wei (未), Shen (申), You (酉), Xu (戌), and Hai (亥). This sequence runs from the Rat through the Pig and governs the 12 two-hour periods of the day, the 12 months, and the 12-year zodiac cycle.

Ten Gods in Bazi
Are the Ten Gods the same as the Chinese zodiac animals?
No. The Ten Gods are derived from element relationships around the Day Master in a Bazi chart. The zodiac animals come from the Earthly Branches and represent a 12-year cycle. They are different layers of the same system.
Can I have more than one Ten God in my chart?
Yes. Most charts contain several Ten Gods across the four pillars. The dominant ones depend on which appear most frequently, which are in the month pillar, and which are activated by the current Luck Pillar.
Is Seven Killings always negative?
No. Seven Killings describes intense authority or pressure energy. In a chart where the Day Master is strong enough to handle it, Seven Killings can indicate leadership, drive, and the ability to work under pressure. Context always matters.
Do Ten Gods change over time?
The natal Ten Gods stay fixed. But Luck Pillars and annual stems bring new Ten God energies into the chart, activating different roles in different decades and years.
How do I calculate the Ten Gods from my Day Master?
Identify the Day Master's element first. The same element is Peer, the element that produces it is Resource, the element it produces is Output, the element it controls is Wealth, and the element that controls it is Authority. Then compare yin-yang polarity to choose the direct or indirect form.
Which Ten God is most important in a chart?
There is no universal most important Ten God. Start with the month pillar, repeated visible and hidden roles, Day Master strength, and the current Luck Pillar. A role becomes important because of position, season, support, and timing rather than its name alone.

Luck Pillars (Da Yun)
When do Luck Pillars start?
The starting age varies by birth date and gender, typically between age 1 and 10. It is calculated from the distance between the birth date and the next seasonal node for forward cycles or the previous seasonal node for reverse cycles in the Chinese calendar.
Can a bad Luck Pillar be avoided?
Luck Pillars describe timing patterns, not fixed outcomes. A challenging pillar highlights areas of pressure and adjustment. Awareness of the pattern allows better preparation, even if the pressure itself cannot be eliminated.
How is a Luck Pillar different from an annual cycle?
A Luck Pillar runs for 10 years and sets the broad decade theme. An annual cycle (Tai Sui) runs for one year and adds a shorter layer of activation. Both interact with the natal chart, but at different timescales.
Do Luck Pillars affect everyone the same way?
No. The same Luck Pillar stem and branch will interact differently with each natal chart. A pillar that strengthens one person's useful elements may create conflict in another person's chart.
Does the Mingli Atlas Bazi calculator generate Luck Pillars?
Yes. Select male or female in the optional gender field to calculate the traditional Da Yun direction, starting date, and ten-year cycles alongside the natal chart. If gender is not specified, the calculator still builds the Four Pillars, Day Master, hidden stems, Ten Gods, and element balance, but omits Luck Pillars. Record the selected rule and time basis before comparing results across methods; these cycles are traditional reference information, not predictions.
Are the stem and branch limited to five years each?
Both remain part of the full 10-year pillar. Some schools give the stem more emphasis earlier and the branch more emphasis later, but this is an interpretive heuristic rather than a rule that switches one component off after five years.
