Four guides for
everyone starting out
BaZi for Beginners
Your starting point. What BaZi is, where it came from, and how to read your own eight-character chart. Written for someone who has never heard of any of this before.
What is a Day Master?
Your Day Master is the most important character in your chart. It represents your core self, and every other character is read in relation to it. Here is what each of the ten Day Masters means.
The Five Elements
Wood, Fire, Earth, Metal, Water: the framework underneath BaZi, feng shui, and Traditional Chinese Medicine. Each element described in plain English, with its role in personality.
Feng Shui Basics
Forget the lucky frogs and wind chimes. Feng shui is a system for arranging the spaces you live in so they support you, and the underlying logic is much simpler than it appears.

Four Pillars of Destiny
The personal chart system at the centre of Chinese astrology. Your eight characters describe your core self, your relationships, your career path, and the timing of your life.
The art of balanced space
The same five-element system applied to where you live and work. Practical, geometric, and surprisingly testable. The right arrangement supports you; the wrong one quietly drains you.

What is Suan Ming?
Suan Ming (算命) means "calculating fate." It is the branch of Chinese metaphysics that reads a person's character and life trajectory from the exact time they were born. A structured discipline refined over more than two thousand years, not fortune-telling in any popular sense.
The core idea: the moment of your birth encodes a pattern of elemental energies that shapes your temperament, your strengths, your challenges, and the broad arc of your life. A reading reveals this pattern. It does not predict fixed events.
Read the full guide to Chinese astrology →The Four Pillars (BaZi 八字)
BaZi means "eight characters." Your year, month, day, and hour of birth each map to a pair of Chinese characters, giving you four pillars and eight characters in total. The upper character of each pillar is a Heavenly Stem (天干). The lower is an Earthly Branch (地支).
| Pillar | From | Governs |
|---|---|---|
| Year | Birth year | Ancestry, early life, public persona |
| Month | Birth month | Parents, career, adult years |
| Day | Birth day | Your core self, marriage |
| Hour | Birth hour | Children, later life, hidden nature |
The Five Elements (Wu Xing 五行)
The five elements are not physical materials. They are energetic qualities, five phases of a single cycle that everything in the universe is thought to pass through. Each element has a character, a season, an emotion, and a role in personality.
| Element | Quality | In a person |
|---|---|---|
| Wood 木 | Growth, expansion | Ambition, creativity, drive to begin |
| Fire 火 | Warmth, visibility | Expression, leadership, social energy |
| Earth 土 | Stability, support | Reliability, patience, care for others |
| Precision, refinement | Discernment, standards, decisiveness | |
| Water 水 | Depth, flow | Intuition, adaptability, reflection |
A chart is read by looking at which elements are present, which are missing, and how they support or control each other. A chart heavy in Fire with no Water suggests brilliance and drive but a risk of burnout, and it points to Water as the remedy.

BaZi describes tendencies. It is a map of natural inclinations, not a fixed prediction. The same chart can express itself very differently depending on your environment, your choices, and your level of self-awareness.
The single most important character is your Day Master (the upper character of the Day Pillar). It represents your core self, and every other character is read in relation to it. Your strengths, your challenges, your lucky element, and your life timing all begin with the Day Master.
Read the BaZi for beginners guide →The Ten Day Masters
There are exactly ten possible Day Masters, one for each of the ten Heavenly Stems. Each one combines a Five Element with a Yang or Yin polarity, which gives ten distinct core types.
| Stem | Day Master | Element · Polarity | Core nature |
|---|---|---|---|
| 甲 | Jiǎ | Wood · Yang | Principled, ambitious, the tree |
| 乙 | Yǐ | Wood · Yin | Adaptive, persistent, the vine |
| 丙 | Bǐng | Fire · Yang | Charismatic, generous, the sun |
| 丁 | Dīng | Fire · Yin | Focused, perceptive, the candle |
| 戊 | Wù | Earth · Yang | Steady, loyal, the mountain |
| 己 | Jǐ | Earth · Yin | Nurturing, practical, the fertile soil |
| 庚 | Gēng | Metal · Yang | Decisive, principled, the sword |
| 辛 | Xīn | Metal · Yin | Refined, discerning, the jewel |
| 壬 | Rén | Water · Yang | Curious, fluid, the ocean |
| 癸 | Guǐ | Water · Yin | Intuitive, deep, the well |
Day Master Strength: Strong, Moderate, or Weak
After your Day Master itself, the next thing a practitioner reads is its strength. Strength is measured by counting how many of the other seven characters in your chart share or generate your Day Master's element.
A Strong Day Master has plenty of elemental support. Its qualities show up fully, sometimes too much. A Weak Day Master has less support; its qualities are present but muted, and you tend to need the right environment and the right people for those qualities to come through clearly. A Moderate Day Master sits between the two and often produces the most balanced version of a given type.
Two people with the same Day Master at different strength levels can feel very different from each other. This is why strength is one of the most important parts of any reading.

Is BaZi the same as the Chinese zodiac?
No. The Chinese zodiac assigns one of twelve animals to your birth year, and that's it. Everyone born in 1990 is a Horse, all 20 million of them. BaZi uses your year, month, day, and hour to produce a full eight-character chart. Two people born in the same year almost always have very different BaZi charts. More on the difference →
How is BaZi different from Western astrology?
Western astrology reads the positions of the sun and planets at your birth. BaZi reads the Chinese lunisolar calendar and its system of Heavenly Stems and Earthly Branches. Two completely separate frameworks. Both try to describe personality and timing, but they use different symbolic languages and different interpretive approaches. More on the comparison →
What if I don't know my birth hour?
You can still get a useful reading from your year, month, and day alone. The Hour Pillar adds nuance around your hidden nature, your children, and your later life, but the core profile from your Day Master and the other three pillars works without it. If you're unsure, pick the range that feels closest.
What does "absent element" mean in my chart?
If one of the five elements doesn't appear in any of your eight characters, it's considered absent. Absent elements point to areas of life where you may need to put in more conscious effort, because the natural support most people have isn't there. For example, an absent Water element suggests you'll need to deliberately build in rest, reflection, and depth, since these won't come automatically from the rest of the chart.
Does my BaZi chart change over time?
Your birth chart is fixed. The four pillars don't change. What changes are the external luck cycles (大運, dà yùn) that interact with your chart. These ten-year periods shift the elemental environment around your fixed chart, which is why the same person can experience very different decades of life. This reading focuses on the natal chart itself, not luck cycle analysis.
