Where the element proportions come from
The full chart stays fixed. The highlighted part shows the selected pillar's contribution; it is not a new percentage or a strength score.
Weights: visible stem 1; branch element 0.6; hidden main / middle / residual qi 0.5 / 0.3 / 0.2.
Now see how the elements relate
Composition tells you how much of each element appears. These arrows answer a different question: how do two elements relate?
Follow one relationship at a time
Choose an element. The arrow shows what it generates or controls; the elements stay in the same places.
Wood generates Fire
From: Wood · To: Fire
These arrows describe traditional relationships, not amounts or a flow measured in your chart. Generating is not always helpful, and controlling is not always harmful.
The Five Elements — Wood, Fire, Earth, Metal, and Water — are the categories used to describe relationships in a Bazi chart. Together they are called Wuxing (五行). Start by learning the generating and controlling directions, then see how they apply to a chart.
Natural images make the names easier to remember: Wood grows, Fire gives warmth, Earth holds, Metal shapes, and Water flows. In a chart, these are symbols with assigned relationships. They do not measure physical substances, and an element’s amount does not establish a person’s temperament.
The Five Elements and What They Represent
Start with these natural processes as memory aids. They introduce the symbols; an element's count or percentage does not establish a personality trait:
| Element | Natural process | Image to remember |
|---|---|---|
| Wood (木) | Growth | A plant extending roots and branches |
| Fire (火) | Warmth and light | Sunlight spreading or a flame burning |
| Earth (土) | Holding and nourishing | Ground supporting roots and gathering water |
| Metal (金) | Shaping and refining | A blade shaping wood or a jewel being polished |
| Water (水) | Flow | A river moving or dew gathering |
The Generating Cycle (相生)
The five elements feed each other in a continuous circle called the generating cycle (相生). Each element nourishes the next, creating a flow of energy that moves around the wheel:
- Wood generates Fire — picture wood feeding a flame to remember the direction.
- Fire generates Earth — ashes left by a fire provide a familiar memory aid.
- Earth generates Metal — remember this link through mineral deposits in the ground.
- Metal generates Water — learn this as a relationship in the traditional cycle. It does not mean that melting metal becomes water.
- Water generates Wood — picture water nourishing a growing plant.
The Controlling Cycle (相克)
The controlling cycle (相克) names a second set of directional relationships. These everyday images help you remember the links; they are not a physical theory or a verdict on someone’s life:
- Wood controls Earth — picture roots working through soil.
- Earth controls Water — picture an earth bank containing water.
- Water controls Fire — picture water extinguishing a flame.
- Fire controls Metal — picture heat softening metal.
- Metal controls Wood — picture a metal blade cutting wood.
What Your Element Balance Reveals
Your chart's element distribution shows how Wood, Fire, Earth, Metal and Water are represented in the calculated pillars. It is a useful way to see the composition at a glance. The proportions do not measure personality, ability or how fortunate a chart is.
If Wood has the largest bar, Wood has the largest weighted share in this tally. Next, find where it appears: in a visible stem, a branch or a hidden stem. Then consider the birth season and its relationship to the Day Master.
The same distribution can play different roles in different charts. Water is Resource for a Wood Day Master, but Authority for a Fire Day Master. Its amount alone cannot tell you whether more Water would help.
Reading Your Own Element Mix
The calculator tallies visible stems, branch elements and hidden stems with stated weights. Each percentage is that element’s share of the weighted total; it is not a measured amount of energy. With unknown birth time, the tally uses only the available three pillars and excludes the Hour Pillar. The example above lets you inspect how each pillar contributes to a fixed total.
Ask three questions: Where does each element appear? Check the stems, branches and hidden stems. How does it relate to the Day Master? Follow the generating and controlling directions. What context changes the reading? Consider the season, roots and overall structure. Equal percentages are not a target.
The Elements and Your Day Master
Your Day Master is the Heavenly Stem at the top of the Day Pillar. It is the reference point for the element relationships. Another element may generate it, share its element, be produced or controlled by it, or control it in turn.
For a Wood Day Master, Water belongs to the Resource family because Water generates Wood. For a Fire Day Master, Water belongs to Authority because Water controls Fire. The relationship is fixed by the elements; whether its amount and placement are useful requires the whole chart.
DAY MASTER RELATIVITY
The same element changes role with the Day Master · 日主相对性
The reference point changes the relationship before any broader judgment is made.
Same element
水
Water
The relationship is read from the Day Master outward.
Wood Day Master
木日主Water generates Wood
Support · nourishment
Water feeds growth and replenishes the reference point.
Fire Day Master
火日主Water controls Fire
Restraint · pressure
Water regulates the flame and can feel like external demand.
Same element ≠ same role
Change the reference point first; only then decide whether an element supports, expresses, regulates, or challenges it.
Putting It All Together
The Five Elements give you a way to follow relationships in a chart. Start with your Day Master, recognize the direction of each relationship, then add the birth season and wider structure. The distribution shows what is present; the reading explains how those parts fit together.

Methodology and sources
These guides explain the traditional Bazi framework as an educational system, not as a guaranteed prediction or professional advice. When you use the calculator, it converts the supplied birth date and time into the Four Pillars, uses the selected location for time-zone and true-solar-time correction, and then reads the Day Master, element relationships, and Life Chapters in context. Results depend on the birth details and calculation conventions you provide.
