Five Elements in Saju: Wood, Fire, Earth, Metal and Water Explained
five elements saju · Education
The five elements, called ohaeng (오행, 五行) in Korean and wuxing in Chinese, are wood, fire, earth, metal and water. In saju and BaZi they are the shared language that connects the eight characters on a chart. Every Heavenly Stem and every Earthly Branch is taught with one of them, and two simple cycles describe how they relate. This guide shows you how to label your chart by element, how the cycles work, and what an element count can and cannot tell you.

Why "elements" is a slightly misleading word
The Chinese term means something closer to "five phases" or "five movements". They are not substances. Wood is not a tree on your chart and water is not a warning about the sea. Each one is a label for a stage in a cycle: growth, peak, balance, contraction and rest. Keeping that in mind avoids most of the dramatic misreadings you see online.
Which character carries which element
Each stem and each branch has one element in the standard teaching.
| Element | Stems (yang, yin) | Branches |
|---|---|---|
| Wood | 甲, 乙 | 寅, 卯 |
| Fire | 丙, 丁 | 巳, 午 |
| Earth | 戊, 己 | 辰, 戌, 丑, 未 |
| Metal | 庚, 辛 | 申, 酉 |
| Water | 壬, 癸 | 亥, 子 |
Earth has four branches because each of them sits at the turn between two seasons. For the readings, polarity and animal of every character, see Heavenly Stems and Earthly Branches: A Saju Chart Reference.
The two cycles
Every pair of elements is connected by one of two relationships.
The generating cycle (상생, sangsaeng) runs in a circle where each element feeds the next:
- Wood feeds Fire.
- Fire produces Earth (ash).
- Earth bears Metal.
- Metal carries Water (condensation).
- Water nourishes Wood.
The controlling cycle (상극, sanggeuk) skips one step each time, so each element restrains another:
- Wood restrains Earth (roots hold soil).
- Earth restrains Water (banks hold a river).
- Water restrains Fire.
- Fire restrains Metal (it melts).
- Metal restrains Wood (an axe).
Neither cycle is "good" or "bad". Generating is not always helpful, because too much feeding can exhaust the giver, and controlling is not always harmful, because restraint can give shape. Readers use the cycles to describe relationships, not to hand out grades.
How to count the elements on your chart
- Generate your chart and write down the eight characters: four stems on top, four branches below. If the time is unknown, you will have six.
- Label each character with its element from the table above.
- Count how many of each you have.
- Circle the stem in the day column. That is your Day Master, and its element is the one other elements are compared with. How to Find Your Day Master shows where it sits.
Here is a worked case, using a made-up birth at 12:00 on 10 February 2024. The calculator gives 甲辰 for the year, 丙寅 for the month, 甲辰 for the day and 庚午 for the hour.
| Element | Characters | Count |
|---|---|---|
| Wood | 甲 (year), 寅, 甲 (day) | 3 |
| Fire | 丙, 午 | 2 |
| Earth | 辰 (year), 辰 (day) | 2 |
| Metal | 庚 | 1 |
| Water | none | 0 |
The Day Master is 甲, yang wood. On a plain count, wood is the most common element and water does not appear among the visible characters.
What a count can and cannot tell you
A count is a starting point, not a verdict. Three cautions apply before you read anything into it.
- Sites count differently. Many schools also count hidden stems, the elements stored inside each branch, and some give extra weight to the month branch because it marks the season. Two sites can show different percentages for the same chart without either being broken.
- A zero is not a missing body part. "No water" on a visible count does not mean something is lacking in your life. Traditional readers look at how the elements interact with the Day Master and with each other before saying anything about balance.
- Elements are not a personality test. Popular lists like "wood people are creative" skip the chart entirely. If a site gives you an element trait with no chart attached, it is storytelling.
For what an interpretation can fairly claim once you go beyond labels, see Saju Reading: What Your Four-Pillar Chart Can (and Can't) Tell You.
Where elements show up next
Elements are also how traditional systems name the relationship between your Day Master and every other stem. Those relationship names are called the ten gods, and each one comes straight from the two cycles above: the element that feeds your Day Master, the one it feeds, the one it restrains, and so on. Learning the cycles now makes that next step much easier.

Checklist before you compare charts
- Same birth data on both sites, including solar or lunar date and birth time.
- Same convention for the day change at midnight; PillarAtlas changes the day at midnight.
- Same counting method: visible characters only, or hidden stems included.
On PillarAtlas the four-pillar chart is free; see Free Saju Reading: What You Get Without Paying. Two-person compatibility readings are not available yet, and purchases are not open, so nothing on the site charges a card.
