Yi wood born in autumn is the soft vine or flowering plant meeting the season of the blade. Your Day Master (日主 rìzhǔ) is Yǐ 乙, the yin wood — grass, creeper, tendril rather than the standing trunk. Autumn in Ba Zi (八字 bāzì) is the Metal season, carried by the branches 申酉戌 and running from Aug 7 to Nov 6, from Li Qiu (立秋 lìqiū) to just before Li Dong (立冬 lìdōng). These are solar-term seasons, not calendar months, so a birthday in early August may still belong to summer until the term turns — confirm the exact boundary on the Butcher Boy calculator before you assign a season at all.
The image is a green plant as the first cold air arrives and the metal of the season begins to cut. Autumn is harvest for grain, but for a living vine it is the moment the growing energy is turned against.
Dormant (死 sǐ): the weakest baseline
The seasonal state here is 死 sǐ — Dormant — the season controls your element: weakest baseline; support and timing matter more than effort. Metal cuts Wood, and autumn is Metal at full authority, so the season stands directly against your element. This is the lowest of the five seasonal states.
For Yi wood the reading is specific. A great Jiǎ 甲 trunk under autumn Metal is being pruned — painful but structural, and a strong tree survives the axe. The yin vine has no such mass to lose; it is simply exposed. Dormant does not mean dead in the literal sense; it means the season gives you nothing and asks a great deal. The tender plant born into Metal’s season learns early that force is not the way through — patience, cover and good timing are.
Officer or Killings: which Metal is pressing
The Ten Gods (十神 shíshén) name the pressure precisely. For a Yǐ Day Master, Gēng 庚 (Yang Metal) is Direct Officer (正官 zhèngguān) and Xīn 辛 (Yin Metal) is Seven Killings (七杀 qīshā). The distinction matters month by month. The Monkey month (申 shēn) hides Gēng 庚, Rén 壬 and Wù 戊 — its main qi is the Officer, structured and rule-bound, and the Rén beside it is the seed of the Water remedy sitting inside the pressure itself. The Rooster month (酉 yǒu) hides Xīn 辛 alone: pure Seven Killings, the sharpest and most demanding footing of the quarter for a yin vine. The Dog month (戌 xū) closes autumn with Wù 戊, Xīn 辛 and Dīng 丁 — one of the four transitional Earth months (辰未戌丑) where Earth strengthens at the season’s end, its hidden Dīng a small flame held against the blade. In a reading, a 申-month Yi and a 酉-month Yi are both dormant, but the first is governed while the second is hunted; the difference in texture is real.
What this season asks of you
Autumn is a power season for Yi wood — the reference line is precise: Metal relative to Wood controls Wood (power/pressure season). Born into your own controlling element, you feel structure, rank and pressure before you feel support. For a weak, dormant Day Master this is a great deal of Officer and Killings weight sitting on a small frame.
The practical need for yi wood born in autumn is resource, allies and timing rather than more effort. Water in the chart drains the Metal and turns pressure back into growth — it is the classic remedy, leading the blade’s force into nourishment instead of a cut. Companions, other Wood, help you carry the load. And because the season itself is against you, favorable luck pillars and years do more heavy lifting here than they would for a stem in season. Do not try to out-muscle autumn; borrow strength and wait for the turn.
This is the weak-side half of the general favorable-elements rule — resource and companions favorable, output, wealth and power unfavorable — subject always to the caveat that season and chart structure can override the rule of thumb. The full element logic for Wood stems is on the favorable elements for Wood Day Masters page.
In charts we read, this combination often belongs to people who achieve under pressure but pay for it in nerves. The Metal is real, the standards are high, and a small Wood Day Master feels every ounce of it. The good news is that the remedy is structural rather than heroic: the right Water in the chart, or a Water-and-Wood run in the luck pillars, changes the whole experience of the same autumn.
The caveats that change everything
A dormant season is only half the verdict. Yi wood born in autumn can still steady itself if the chart carries Water resource, Wood roots in the other branches, or hidden stems (藏干 cánggān) that quietly feed the Day Master. Conversely, an autumn stacked with more Metal and no Water is the genuinely difficult version, where the pressure has nothing to soften it. The season names the climate; the roots and the rest of the chart decide whether the vine is cut down or merely bent.
So treat the label as a starting point, not a sentence. Run the full strong versus weak Day Master assessment, and read how this particular stem meets the world in the Yi Wood Day Master profile. To see the same vine once the season swings back to its favor, compare Yi wood born in winter, where Water feeds rather than the Metal presses — and for the full arc, set both against Yi wood born in spring, the vine in its own prosperous quarter, and Yi wood born in summer, where the drain is chosen rather than imposed. Autumn is the one quarter of the four that opposes this stem outright, which is why its remedies are the most specific and its luck-pillar timing the most consequential.
Before you read autumn as a hard season, make sure both halves are right — that Yǐ wood is truly your Day Master and that your birth sits inside the autumn solar terms. Plot your chart free with the Butcher Boy calculator and judge the season against your roots, not the month on the wall.
