The Yi Wood character
Adaptable and quietly persistent: you find the way around, not through. Charm and networks are your real strength. These are traditional images, not rules: the rest of the chart (season, roots, the other stems) decides how much of this shows.
How the other stems appear to Yi Wood
In BaZi each stem plays one of ten roles for the Day Master. This table is computed for 乙:
| Stem | Ten god | In plain English |
|---|---|---|
| 甲 Jia (Wood) | 劫財 | Rival |
| 乙 Yi (Wood) | 比肩 | Peer |
| 丙 Bing (Fire) | 傷官 | Maverick |
| 丁 Ding (Fire) | 食神 | Artist |
| 戊 Wu (Earth) | 正財 | Steady Wealth |
| 己 Ji (Earth) | 偏財 | Windfall Wealth |
| 庚 Geng (Metal) | 正官 | Authority |
| 辛 Xin (Metal) | 七殺 | Challenger |
| 壬 Ren (Water) | 正印 | Nurturer |
| 癸 Gui (Water) | 偏印 | Mystic |
Yi Wood in 2027
The 2027 year pillar is 丁未. For a 乙 Day Master the year stem 丁 is 食神 (Artist) and the main qi of 未, 己 Earth, is 偏財 (Windfall Wealth). Whether that helps depends on your chart's strength; Your 2027 works it out month by month. 乙 days come every ten days; in February 2027 they fall on Feb 5, Feb 15 and Feb 25.
Strong and weak Yi Wood
A 乙 Day Master is strong when the chart has plenty of Wood and Water (which feeds it), especially if born in spring. Then Fire (its output), Earth (its wealth) and Metal (its discipline) bring balance. It is weak when Fire, Earth and Metal dominate; then Water and fellow Wood help most. Our profile scores this from 0 to 100 rather than guessing.
Yi Wood and the other stems
乙 combines with 庚, a pairing read as attraction or partnership. 辛 (same polarity, Metal) presses 乙 directly, and 乙 presses 己 (Earth) in turn. These stem relations matter in compatibility readings and when a year's stem meets your chart.
Traditional associations
Wood is linked with growth, planning, kindness and the east; in classical images it is the tree (yang) or the vine and grass (yin). Its color is green, and on askjoss its guardian is Qilin (The Gentle Protector), our storytelling layer for the Wood element.
How askjoss computes it
Your Day Master is the stem of your day pillar after the true-solar-time correction. Its strength is scored from the season, roots in the branches and supporting stems; we then choose favorable elements by simplified strength-balance rules. Full notes, including every simplification, are on How we calculate.
Common misconceptions
- "Every Yi Wood person is the same." One tenth of people share each Day Master; the season and the other seven characters change the picture a lot.
- "Wood is always my lucky element." A strong Wood chart often needs the element that channels it, not more of the same.

Frequently asked questions
What element is Yi Wood?
乙 is yin Wood, the 2nd of the ten heavenly stems.
What is Yi Wood's best element?
It depends on the chart. A weak 乙 usually welcomes Water (which feeds it) or Wood; a strong one usually welcomes Fire, Earth or Metal.
Which stem combines with 乙?
庚. Stem combinations (天干五合) pair 乙 with 庚 and are read as attraction or partnership in a chart.
