What is Bazi?
Bazi (八字), literally meaning "Eight Characters," is one of the most sophisticated and time-tested systems of Chinese astrology. Known in English as the Four Pillars of Destiny (四柱命理), this ancient practice has guided emperors, scholars, and ordinary people alike for over three millennia. Unlike Western horoscopes that focus primarily on sun signs, Bazi creates a comprehensive blueprint of your life based on the exact moment of your birth.
What Does "Bazi" Mean?
The term "Bazi" (八字) translates to "Eight Characters" because your chart consists of exactly eight Chinese characters—two for each of the four pillars representing the year, month, day, and hour of your birth. Each character is composed of a Heavenly Stem (天干) on top and an Earthly Branch (地支) below, creating a unique cosmic signature that belongs only to you.
In classical Chinese texts, Bazi is also referred to as: - Zi Ping Ming Xue (子平命學) - Named after the Tang Dynasty master Xu Ziping - Ming Li (命理) - The study of destiny - Si Zhu (四柱) - Four Pillars
The Historical Origins of Bazi
Ancient Roots (3,000+ Years Ago)
The foundations of Bazi trace back to the Shang Dynasty (1600-1046 BCE), when Chinese astronomers developed the Heavenly Stems and Earthly Branches calendar system. Archaeological evidence from oracle bone inscriptions shows that this sexagenary (60-year) cycle was already in use for recording dates and making divinations.
According to the Book of Documents (尚書), one of the Five Classics of ancient Chinese literature, the cosmic principles underlying Bazi were understood as early as the Zhou Dynasty (1046-256 BCE). The I Ching (易經), dating back over 3,000 years, established the philosophical framework of yin-yang and change that Bazi relies upon.
Classical Development (Tang & Song Dynasties)
The systematic methodology of Bazi as we know it today was formalized during the Tang Dynasty (618-907 CE) by the scholar Li Xuzhong (李虛中). He developed the three-pillar system using year, month, and day of birth.
The complete four-pillar system emerged during the Song Dynasty (960-1279 CE) when Xu Ziping (徐子平) added the hour pillar and refined the analytical framework. His contributions were so significant that Bazi is sometimes called "Ziping Bazi" (子平八字) in his honor. The classic text Yuan Hai Zi Ping (淵海子平), compiled during this era, remains one of the most authoritative references on Bazi methodology.
Imperial Adoption (Ming & Qing Dynasties)
During the Ming (1368-1644) and Qing (1644-1912) Dynasties, Bazi analysis became institutionalized within the imperial court. The San Ming Tong Hui (三命通會), compiled by Wan Minying during the Ming Dynasty, is a comprehensive encyclopedia of Bazi containing over 600,000 characters. This text, along with Di Tian Sui (滴天髓), forms the foundation of classical Bazi study.
How Does Bazi Work? The Core Principles
Yin-Yang Theory (阴阳)
At the heart of Bazi lies the principle of Yin and Yang—the two complementary forces that permeate all existence. This concept, first articulated in the Tao Te Ching and I Ching, describes how opposing forces are interconnected and interdependent.
- Yang (陽): Represents active, bright, expansive, masculine energy
- Yin (陰): Represents passive, dark, contractive, feminine energy
In Bazi, each of the ten Heavenly Stems is classified as either yin or yang: - Yang Stems: 甲 (Jia-Wood), 丙 (Bing-Fire), 戊 (Wu-Earth), 庚 (Geng-Metal), 壬 (Ren-Water) - Yin Stems: 乙 (Yi-Wood), 丁 (Ding-Fire), 己 (Ji-Earth), 辛 (Xin-Metal), 癸 (Gui-Water)
A person with predominantly yang energy tends to be more outgoing, assertive, and action-oriented, while those with more yin energy are often introspective, receptive, and nurturing.
The Five Elements (五行 Wu Xing)
The Five Elements—Wood, Fire, Earth, Metal, and Water—form the backbone of Bazi analysis. This theory, documented in texts like the Huangdi Neijing (黃帝內經) and used extensively in Traditional Chinese Medicine, describes how these fundamental energies interact.
| Element | Chinese | Nature | Season | Direction | Organ |
|---|---|---|---|---|---|
| Wood | 木 (Mù) | Growth, flexibility | Spring | East | Liver |
| Fire | 火 (Huǒ) | Passion, transformation | Summer | South | Heart |
| Earth | 土 (Tǔ) | Stability, nurturing | Late Summer | Center | Spleen |
| Metal | 金 (Jīn) | Precision, clarity | Autumn | West | Lungs |
| Water | 水 (Shuǐ) | Wisdom, adaptability | Winter | North | Kidneys |
The elements interact through two primary cycles:
The Generating Cycle (相生): Wood → Fire → Earth → Metal → Water → Wood
The Controlling Cycle (相克): Wood → Earth → Water → Fire → Metal → Wood
Understanding which elements are strong, weak, or absent in your chart reveals your innate strengths, potential challenges, and areas for growth.
The Ten Heavenly Stems (十天干)
The Heavenly Stems are ten symbols combining the five elements with yin-yang polarity:
| Stem | Pinyin | Element | Polarity | Image |
|---|---|---|---|---|
| 甲 | Jiǎ | Wood | Yang | Towering tree |
| 乙 | Yǐ | Wood | Yin | Grass, vines |
| 丙 | Bǐng | Fire | Yang | Sun |
| 丁 | Dīng | Fire | Yin | Candle flame |
| 戊 | Wù | Earth | Yang | Mountain |
| 己 | Jǐ | Earth | Yin | Garden soil |
| 庚 | Gēng | Metal | Yang | Sword, axe |
| 辛 | Xīn | Metal | Yin | Jewelry, needle |
| 壬 | Rén | Water | Yang | Ocean, river |
| 癸 | Guǐ | Water | Yin | Rain, dew |
The Twelve Earthly Branches (十二地支)
The Earthly Branches correspond to the twelve Chinese zodiac animals and form the foundation of the Chinese calendar system:
| Branch | Animal | Element | Polarity | Time |
|---|---|---|---|---|
| 子 (Zǐ) | Rat | Water | Yang | 23:00-01:00 |
| 丑 (Chǒu) | Ox | Earth | Yin | 01:00-03:00 |
| 寅 (Yín) | Tiger | Wood | Yang | 03:00-05:00 |
| 卯 (Mǎo) | Rabbit | Wood | Yin | 05:00-07:00 |
| 辰 (Chén) | Dragon | Earth | Yang | 07:00-09:00 |
| 巳 (Sì) | Snake | Fire | Yin | 09:00-11:00 |
| 午 (Wǔ) | Horse | Fire | Yang | 11:00-13:00 |
| 未 (Wèi) | Goat | Earth | Yin | 13:00-15:00 |
| 申 (Shēn) | Monkey | Metal | Yang | 15:00-17:00 |
| 酉 (Yǒu) | Rooster | Metal | Yin | 17:00-19:00 |
| 戌 (Xū) | Dog | Earth | Yang | 19:00-21:00 |
| 亥 (Hài) | Pig | Water | Yin | 21:00-23:00 |
Understanding the Four Pillars
Your Bazi chart consists of four pillars, each representing different aspects of your life:
Year Pillar (年柱)
The Year Pillar represents: - Your ancestry and family background - Social environment and external circumstances - Childhood (ages 1-16) - Grandparents and extended family
The Earthly Branch of your Year Pillar is your Chinese zodiac animal, which shapes your outward persona and how others initially perceive you.
Month Pillar (月柱)
The Month Pillar is considered the "root of destiny" (命之根) because it captures the seasonal energy at your birth: - Parents and siblings - Career and professional life - Young adulthood to middle age (ages 17-32) - Your inherent talents and abilities
The Month Pillar's Earthly Branch determines your "Month Commander" (月令), one of the most crucial factors in chart analysis.
Day Pillar (日柱)
The Day Pillar is the most important pillar because its Heavenly Stem represents your Day Master (日主)—your core self: - Your essential nature and identity - Marriage and romantic relationships - Adult life (ages 33-48) - Your spouse (in traditional interpretation)
All other elements in the chart are analyzed in relation to the Day Master.
Hour Pillar (時柱)
The Hour Pillar reveals: - Your children and descendants - Career achievements and legacy - Later life (ages 49 and beyond) - Inner desires and subconscious drives
The Hour Pillar is sometimes called the "Pillar of Secret Thoughts" because it reflects your innermost aspirations.
The Ten Gods (十神) System
One of Bazi's most powerful analytical tools is the Ten Gods system, which describes how each element in your chart relates to your Day Master:
| Ten God | Relationship | Meaning |
|---|---|---|
| Companion (比肩) | Same element, same polarity | Friends, competitors, peers |
| Rob Wealth (劫财) | Same element, opposite polarity | Rivals, siblings, collaboration |
| Eating God (食神) | You generate, same polarity | Creativity, expression, children |
| Hurting Officer (伤官) | You generate, opposite polarity | Rebellion, intelligence, innovation |
| Direct Wealth (正财) | You control, opposite polarity | Stable income, spouse (for men) |
| Indirect Wealth (偏财) | You control, same polarity | Windfall, father, opportunity |
| Direct Officer (正官) | Controls you, opposite polarity | Authority, career, discipline |
| Seven Killings (七杀) | Controls you, same polarity | Pressure, power, ambition |
| Direct Resource (正印) | Generates you, opposite polarity | Support, mother, education |
| Indirect Resource (偏印) | Generates you, same polarity | Unconventional knowledge, intuition |
Luck Pillars (大運): Your Life Cycles
Unlike static horoscopes, Bazi incorporates Luck Pillars (大運)—ten-year cycles that influence different periods of your life. These cycles interact with your natal chart, bringing new opportunities and challenges.
As the ancient text Qiong Tong Bao Jian (穷通宝鉴) states: "The natal chart is like the seedling; the Luck Pillars are the seasons." Even an excellent natal chart needs favorable Luck Pillars to flourish, just as a seed needs the right season to grow.
Understanding your upcoming Luck Pillars allows you to: - Time major decisions (career changes, marriage, investments) - Prepare for challenges before they arrive - Maximize opportunities during favorable periods
How Accurate is Bazi?
Bazi has been refined over three millennia through the analysis of millions of charts. While it cannot predict specific events with certainty, it excels at revealing:
- Personality patterns and behavioral tendencies
- Relationship dynamics and compatibility
- Career aptitudes and professional strengths
- Health predispositions based on elemental balance
- Favorable timing for major life decisions
Modern practitioners often combine Bazi with other Chinese metaphysical systems like Feng Shui, Qi Men Dun Jia, and face reading for comprehensive life analysis.

Frequently Asked Questions
Is Bazi the same as Chinese Zodiac?
No. While the Chinese Zodiac uses only your birth year (giving 12 possible types), Bazi uses year, month, day, and hour, creating over 12.9 million possible combinations—making it far more personalized.
Does Bazi determine fate?
Traditional Bazi philosophy holds that while your chart shows tendencies and potential, your choices and actions matter. The saying "一命二运三风水四积阴德五读书" (First destiny, second luck, third feng shui, fourth good deeds, fifth education) suggests multiple factors shape your life.
How is Bazi different from Western astrology?
| Aspect | Bazi | Western Astrology |
