Ch 1: Getting Started — Your Birth Time Code

The foundation of BaZi chart reading: what the Four Pillars are, how the Five Elements interact, what the Ten Gods represent, and how to find the key that unlocks any chart.

1.1 What Is a BaZi Chart?

"BaZi" literally means "Eight Characters." It refers to the eight symbols that represent your exact moment of birth — year, month, day, and hour, each expressed as two characters: a Heavenly Stem（天干，top）and an Earthly Branch（地支，bottom）. Think of it as a time-stamp written in an ancient coding system.

The Ten Heavenly Stems（天干）: Jia（甲）, Yi（乙）, Bing（丙）, Ding（丁）, Wu（戊）, Ji（己）, Geng（庚）, Xin（辛）, Ren（壬）, Gui（癸）. These are ten distinct energy types, like ten different frequencies of light.

The Twelve Earthly Branches（地支）: Zi（子）, Chou（丑）, Yin（寅）, Mao（卯）, Chen（辰）, Si（巳）, Wu（午）, Wei（未）, Shen（申）, You（酉）, Xu（戌）, Hai（亥）. Each corresponds to one of the twelve Chinese Zodiac animals, and each contains hidden elemental energies (called "hidden stems"（藏干）).

These stems and branches combine in a fixed sequence to form sixty unique pairs — known as the Sixty Jiazi Cycle（六十甲子）. This cycle repeats every 60 years, which is why your 60th birthday is traditionally a major milestone in Chinese culture.

Example: Someone born on May 20, 2000, at 3 PM would have these four pillars:

Months and hours follow fixed branch assignments: The first lunar month always falls on Yin (Tiger), the second on Mao (Rabbit), and so on. Hours are counted in 2-hour blocks — 11 PM to 1 AM is Zi, 1 AM to 3 AM is Chou, and so forth. This is based on the solar calendar, not the lunar calendar.

The Hidden Stems（藏干） inside each branch are essential knowledge — memorize them. Each Earthly Branch contains one, two, or three hidden Heavenly Stems, and these hidden elements play a major role in chart analysis.

1.2 The Five Elements（Wu Xing 五行）

The Five Elements — Wood, Fire, Earth, Metal, Water — are the fundamental forces that flow through every BaZi chart. They interact through two basic dynamics:

Generation Cycle（相生, who feeds whom）: Wood feeds Fire → Fire creates Earth (ash) → Earth yields Metal (ore) → Metal produces Water (condensation) → Water nourishes Wood. Like a circle of support, each element nourishes the next.

Control Cycle（相克, who restrains whom）: Wood parts Earth (roots break soil) → Earth dams Water (banks hold rivers) → Water extinguishes Fire → Fire melts Metal → Metal cuts Wood (axes fell trees). This is the system of checks and balances.

But these are just the basics. In practice, there are nuances: reverse control (when Wood is so abundant it overwhelms Metal instead of being cut) and failed generation (when Wood is so plentiful that Fire can't consume it all). These deeper dynamics will come up in real chart readings. Want to see which elements dominate your own chart? Try the Five Elements Calculator.

Seasonal strength matters: Each element has a different level of vitality depending on the season. In summer, Fire is at peak strength, Earth is supportive, Wood is resting, Water is imprisoned, and Metal is at its weakest. This seasonal vitality is one of the factors used to assess whether your chart is "strong" or "weak."

1.3 The Twelve Life Stages（Chang Sheng 长生十二宫）

There are currently two points of debate regarding the Twelve Life Stages.

a. Yin and Yang share the same birth and death（阴阳同生共死）

b. Yang is born where Yin dies, Yin is born where Yang dies（阳生阴死，阴生阳死）

The author tends to agree with the first view. There has been considerable controversy since ancient times, so it is worth explaining why the author favors "shared birth and death" — though there are also some points of personal doubt. Below are the commonly used states under the shared-birth-and-death framework:

Birth（长生）, Official/Lu（临官/禄）, Peak/Ren（帝旺/刃）, Tomb（墓）, Death（死）, Extinction（绝）

The author's personal doubt mainly concerns the Birth（长生）state. Below is the analysis. First, we need to clarify two points:

a. Heavenly Stems represent the tangible; Earthly Branches represent the atmosphere（天干主实，地支主气）

b. Numerology at its core imitates the laws of Heaven — that is, the laws of nature. Since it imitates natural laws, numerology can be applied to anything that conforms to the way of nature（命理学本质是模仿天道规律，也可以说是模仿大自然规律）

With these two points in mind, let's look at the differences in the Birth stage among the Ten Heavenly Stems.

Wood (Jia, Yi) is born in Hai（亥）:

Since the Stems represent tangible form, we can work with imagery. Jia is born in Hai — the great tree enters dormancy in early winter, but Ren Water nourishes its roots and sustains its strength, hence Birth. But Yi is different — Yi can be likened to grass and flowers, which in early winter are certainly not as resilient as Jia Wood. Yi is essentially in a state of dormancy, so Yi does not necessarily have its Birth in Hai. However, if the chart is full of warm sunlight, then Yi too can be "born" here. Therefore, the view that Yi "dies" in Hai under the "Yang born, Yin dies" framework does have some merit.

Fire (Bing, Ding) is born in Yin（寅）:

Bing Fire being born in early spring is easy to understand, but Ding Fire is not so certain. Although Wood energy is strong in early spring, it is still a season of cold returning to warmth — a single snowstorm could extinguish it. Ding Fire can be likened to human fire; in cold and damp conditions it may not ignite at all. Mao（卯）would be slightly more favorable.

Earth (Wu, Ji) is born in Yin（寅）:

Fire and Earth share the same palace, and the logic here is similar. Wu Earth is like mountain earth — receiving early spring's Bing Fire, it brims with vitality. Ji Earth is garden soil — receiving Bing Fire, it becomes vibrant. But when they encounter Ding Fire, they may be suspected of extinguishing it. Cold, damp earth receiving Ding Fire is welcome but not enough; Wu is somewhat better in this regard.

Metal (Geng, Xin) is born in Si（巳）:

Metal in early summer — warm but not blistering, gentle with a quality like warm, polished jade — hence Birth. But if Fire is excessive, Metal does not experience Birth; instead, it becomes brittle（脆金）.

Water (Ren, Gui) is born in Shen（申）:

Ren Water born in autumn — Metal generates the water source, and a great river's water is the perfect outlet for strong Metal's killing energy, flowing endlessly — hence Birth. But Gui Water is a clear spring; how can it drain the energy of stubborn Metal? Instead, Metal would muddy the Water. Unless the chart has abundant Water to dilute the Metal, Gui Water in Shen is not necessarily "born" — it depends on the situation.

Therefore, when reading the Favorable Element（用神）, always read the original chart first, then apply the Twelve Life Stages to determine favorable and unfavorable positions.

1.4 The Ten Gods（Shi Shen 十神）

The Ten Gods describe the relationships between the Day Master（日主，your core self） and every other element in your chart. Think of them as ten different roles that other people, events, and energies play in your life story.

The names (Resource, Output, Wealth, Power, Companion) are just labels for convenience — you could call them A, B, C, D, E and the system would work the same. The ancient practitioners named them descriptively to make them easier to remember and apply.

1.5 Reading the Ten Gods — Real-Life Meanings

Each Ten God has a "symbolic range" — a set of real-life associations that experienced readers use to interpret charts. These associations differ slightly for men and women, but here are the core meanings:

1.6 Branch Interactions — Combine（合）, Clash（冲）, Harm（害/穿）, Punish（刑）, Break（破）

The Earthly Branches in your chart don't just sit there — they actively interact with each other. These interactions are what make chart reading dynamic rather than static. Here are the major types:

1.6.1 Heavenly Stem Combinations（天干合） (Stem-to-Stem)

Five pairs of stems combine: Jia-Ji, Yi-Geng, Bing-Xin, Ding-Ren, Wu-Gui. When your Day Master combines with another stem, it shows what you're drawn toward — combining with Wealth means you chase money; combining with Power means you're drawn to authority. Combining with Jia or Bing (when they represent Power) often indicates a career in government or public service.

1.6.2 Six Branch Combinations（地支六合） (Branch-to-Branch)

Six pairs of branches combine（合）: Zi-Chou, Mao-Xu, Si-Shen, Wu-Wei, Chen-You, Yin-Hai. These represent connections and "getting something under control." But the outcome depends on which element is stronger in the overall chart. For example, in a Si-Shen combination: if Fire dominates, Fire controls Metal (Shen); if Metal is strong, Metal controls Fire (Si).

1.6.3 Three-Branch Harmonies（三合局）

Four groups of three branches harmonize to form a pure element: Yin-Mao-Chen → Wood, Si-Wu-Wei → Fire, Shen-You-Xu → Metal, Hai-Zi-Chou → Water. These are powerful formations that can change the elemental balance of the entire chart. They're sometimes used to determine the chart pattern (Ge).

1.6.4 Three-Branch Meetings（三会局, Hui Ju）

Similar to harmonies but even stronger: Yin-Mao-Chen (center on Mao), Si-Wu-Wei (center on Wu), Shen-You-Xu (center on You), Hai-Zi-Chou (center on Zi). These are like elemental super-charges — when all three branches are present, the central branch's energy dominates.

1.6.5 Stem-Branch Self-Combinations（干支自合）

Nine groups where a Heavenly Stem combines with its own Earthly Branch. The most significant are: Wu-Zi, Gui-Si, Ren-Wu, Xin-Si, Ding-Hai — where the stem combines with the branch's primary hidden stem. These often indicate the chart owner's deep-seated ambitions.

1.6.6 Punishments（Xing 刑）

Three main punishments（刑）: Yin-Shen-Si (ungrateful/无恩), Chou-Wei-Xu (bullying/恃势), Zi-Mao (rude/无礼). Plus self-punishment (e.g., You-You, Hai-Hai). Punishments primarily indicate harm or damage — but only when all three branches of a punishment are present. Two branches in a punishment relationship usually mean "gaining control" rather than harm.

1.6.7 Clashes（Chong 冲）

Six pairs: Zi-Wu, Mao-You, Chou-Wei, Si-Hai, Chen-Xu, Yin-Shen. Clashes are direct confrontations — the most obvious form of conflict in a chart. Think of them as the same polarity's mortal enemies: not just repelling each other but actively fighting. They can cause separation, sudden change, or physical relocation — but also "activation" (stirring dormant energy into motion).

1.6.8 Harms（Hai 害/穿）

Six pairs: Zi-Wei, You-Xu, Chou-Wu, Mao-Chen, Shen-Hai, Yin-Si. Harms are like concentrated spear thrusts — the Four Pure branches (Zi, Wu, Mao, You) "pierce" the Four Tombs（四墓库：Chen, Xu, Chou, Wei）. It's a fight to the finish: either the spear breaks through or the shield holds. Harms represent ruthless, sometimes cruel damage — but also the gaining of control.

1.6.9 Breaks（Po 破）

Three pairs: Zi-Mao, Mao-Wu, You-Wu. Breaks represent minor friction — small-scale damage, like getting a scrape rather than a serious wound. They're the weakest of the negative branch interactions.

Understanding the pattern: Breaks, Clashes, and Harms form a hierarchy. Breaks = small friction between same-nature elements. Clashes = full-scale war between mortal enemies. Harms = a concentrated strike where only one side survives. Think of Breaks as a sibling argument, Clashes as a bar fight, and Harms as a sniper shot.

1.7 The Nature of Each Heavenly Stem

Each Heavenly Stem has a distinct personality — like ten different characters in a play. Understanding these personalities helps you "see" the chart as a living story rather than an abstract diagram.

1.8 The Four Tombs（Si Mu Ku 四墓库）

The Four Tombs（四墓库）are Chen（辰）, Xu（戌）, Chou（丑）, and Wei（未）. They serve as the "storage vaults" for the three hidden stems within each Earthly Branch.

The Four Tombs — Chen, Xu, Chou, Wei — are the storage vaults of the BaZi system. Think of them as warehouses: when they're useful (storing something your chart needs), they bring wealth and status. When they're useless, they function more like actual tombs — burying things you need.

Opening and closing the tomb（开库/闭库）: When a tomb clashes with its opposite (e.g., Chen meets Xu), it "opens" — releasing whatever is stored inside. Whether this is good or bad depends on what's inside and whether your chart needs it. Example: if your Wealth is stored in Chen and Xu arrives, your wealth vault opens — great if you need money, terrible if Wealth is your unfavorable element.

Entering the tomb（入墓, Ru Mu）: When a Luck Cycle brings a tomb branch, the corresponding elements in your natal chart may "enter the tomb" — their influence is suppressed. This is generally dangerous for Output (creativity/talent) and family stars. Whether it's auspicious or inauspicious depends on whether the buried element is favorable or unfavorable.

1.9 The Si (Snake) — A Special Branch

The Earthly Branch Si (Snake) is unique — it behaves like a chameleon, especially around Metal. When Fire is dominant, Si behaves as Fire and controls Metal. But when Metal is strong, Si can "switch sides" and act as Metal's Birth stage (since Fire and Earth share the same palace). Always weigh the relative strengths before deciding which side Si takes in any chart.

1.10 Spotting Scams — Red Flags（常见骗术） in Real Readings

Here are the telltale signs of an inexperienced or dishonest practitioner:

1. Vague, generic statements with no specifics. A skilled reader should be able to pinpoint the year something significant happened — not just "you had some challenges in your thirties."
2. Relying entirely on Spirit Stars (Shen Sha). Someone who sees "Yin-Yang Error"（阴差阳错） and immediately declares a bad marriage, or spots "Noble Helper" and predicts great wealth, is cutting corners. Spirit Stars are supplementary at best.
3. Not verifying the chart with past events first. A responsible reader always "reads the past" before predicting the future — both to validate the chart's accuracy and to demonstrate credibility. If someone jumps straight to predictions without confirming any past events, be cautious.

1.11 Strong or Weak: Does It Matter?

The short answer: yes, but it's not the most important thing. Many beginners get obsessed with determining whether the Day Master is "strong" or "weak" — but this alone tells you very little about someone's life.

A strong Day Master（身强）doesn't guarantee wealth or good health. A weak Day Master（身弱）doesn't guarantee poverty or illness. Strength and weakness describe the climate of your chart, not your destiny.

The three indicators of strength:

• In Season (De Ling 得令): The Month Branch contains the same element as your Day Master — like a plant growing in its native season.
• Has Roots (De Di 得地): The Earthly Branches contain your Day Master's element — like a tree with deep roots.
• Has Support (De Shi 得势): The Heavenly Stems contain elements that produce or mirror your Day Master — like having a team backing you up.

Even when all three are present, you must compare against the overall chart to determine true strength — and check whether your roots or resources have been damaged.

1.12 Chart Patterns（Ge Ju 格局）

Chart patterns are determined primarily from the Month Branch. The standard Eight Patterns are: Officer Pattern, Resource Pattern, Wealth Pattern, Output Pattern — plus the Lu (Prosperity) Pattern, Blade Pattern, Mixed-Qi Pattern, and Extreme patterns like Following Patterns（从格）.

Important: Having a "pattern" doesn't automatically mean good fortune, and not having one doesn't mean bad fortune. Everything depends on the overall combination of elements. As the old saying goes: "True teachings are one sentence; false teachings fill ten thousand books." In practice, most people's charts don't form a clean pattern — the conditions are quite strict. Don't worry about it.

Some practitioners consider Following Patterns (Cong Ge) especially auspicious, but these have obvious flaws: when the chart is good, it's very good; when it turns bad, it's very bad. The conditions for identifying a Following Pattern are also notoriously difficult to judge.

1.13 Finding Your Favorable Element（Xi Yong Shen 喜用神）

What is the Favorable Element?

Think of your chart as a room. If the room is too hot, you need air conditioning. If it's too cold, you need a heater. The Favorable Element is whatever brings your chart's "room" closer to a comfortable temperature — not necessarily the element that's most lacking, but the one that creates the most harmony. You can also look up your Favorable Element using our dedicated guide →

A counterintuitive example: If your chart has excessive Fire, many beginners assume you need Water to cool it down. But Water and Fire in direct conflict create steam and chaos — they fight each other. The real solution might be Damp Earth (Chen, Chou), which gently absorbs the Fire's heat without triggering a war. This is why understanding the Favorable Element requires more than just counting elements.

A quick intuitive test: What colors are you naturally drawn to? What environments make you feel most alive? Your instincts often point toward your Favorable Element — just translate the feeling into its corresponding Five Element.

Key Terms

• Yong Shen（用神, Useful God）: The primary tool your chart needs — like reaching for a hammer when you need to drive a nail. If you're weak and need support, Resource is your Yong Shen.
• Xi Shen（喜神, Joy God）: The element that protects your Yong Shen. If your Yong Shen is Resource, then Wood (which produces Resource) would be your Xi Shen.
• Ji Shen（忌神, Forbidden God）: The element that harms you — your Yong Shen's enemy. If you need Resource but Wealth appears, Wealth attacks Resource, making it your Ji Shen.
• Xian Shen（闲神, Idle God）: An element that neither helps nor harms — neutral. But "idle" elements can transform into favorable or unfavorable ones depending on the Luck Cycle.

How to Find Your Favorable Element — Step by Step

1. Identify the imbalance. Which element is dominant? Which is lacking? Start with the obvious — like noticing that a room is too hot or too cold.
2. Find what restores balance. This isn't always the missing element. Sometimes you need a "bridge" element that mediates between conflicting forces, or a "drain" element that channels excess energy productively.
3. Verify with the whole chart. The Favorable Element must work in context — it shouldn't create new problems while solving existing ones.

A Beginner's Framework for Reading Any Chart

The traditional approach (start with strength/weakness, then patterns, then Ten Gods) is solid theory — the "Dao" (principle). But for practical results, the author recommends a different starting point:

1. What does the Day Master want to do? Look at what your Day Master is actively reaching for — combining with Wealth, combining with Power, controlling something. If there's a clear "goal" in the chart, that's the primary storyline. If the Day Master shows no clear ambition, look to the Day Branch instead (combinations, clashes, piercings on the Day Branch often reveal the person's actual path).
2. Is there a faction war? If no clear individual ambition, look for elemental factions — Wood-Fire vs. Metal-Water, Fire-Dry-Earth vs. Water-Damp-Earth. When one faction clearly dominates another, it indicates significant achievement (controlling Power = gaining authority; controlling Wealth = gaining money). The danger is "reversal" — when a Luck Cycle brings the opposing faction and flips the balance.
3. Read the imagery（Xiang Fa 象法）. If neither of the above applies, read the chart as a picture. The most refined method — and the hardest to master. What image does the chart present? A peaceful landscape or a battlefield? Every element contributing to a harmonious picture = high achievement. Disconnected, warring elements = lower achievement.
4. Ambiguous charts. If none of the above methods yield a clear picture, the chart likely belongs to someone who works with their hands for a living. Not a negative judgment — just a realistic assessment of the chart's capacity.
