To be geng metal born in spring is to bring the blade into the season of the tree. Gēng 庚 is Yang Metal, the raw form: the axe-head, unrefined ore, weaponry before the whetstone touches it. Spring is the Wood season, running through the branches 寅卯辰 from Li Chun (立春 lìchūn) around February 4 to just before Li Xia (立夏 lìxià) around May 4. Note that Ba Zi (八字 bāzì) seasons follow the solar terms, not the calendar months, so a birthday in early February or early May can fall on either side of the line. Confirm the true boundary with the free chart calculator before you read yourself as a spring-born Geng.
The image here is precise. Metal is the thing that cuts Wood, and spring is Wood at its most alive. The blade is surrounded by exactly what it was made to work on, yet the season belongs to the timber, not the axe.
Confined (囚 qiú): the blade working against the season
The seasonal state for geng metal born in spring is 囚 qiú, Confined: your element controls the season, so you are fighting uphill against the times. It is the effortful, gritty state. This is not the weakest baseline a Day Master can hold, but it is the one that feels most like labour, because Metal here is spending itself controlling the abundant Wood all around it.
For raw Geng specifically, the reading is a blade swung at a whole forest. The axe is real and sharp, but the sheer volume of green wood dulls the edge and tires the arm. There is a great deal of material to work with and not quite enough force to work all of it. People carrying this combination often feel capable and stretched at the same time, which is the honest signature of Confined.
What this season asks of geng metal born in spring
Spring is Wood, and Wood is what Metal controls, so classically this is a wealth season for Geng: the element you subdue is the element you profit from. That framing changes the whole task. The forest is not the enemy, it is the harvest.
Because the state is Confined rather than Prosperous, the practical advice is the advice for a weaker position. Look for resource and allies before you look for more targets. Metal is strengthened by Earth that produces it and by other Metal that stands beside it, and it is genuinely helped by a little Fire to forge the raw ore into a usable tool. A Geng that has been tempered can cut far more Wood than one that is merely hard. In timing terms, the strong stretches of a Metal or Earth luck pillar are when the wealth of the season finally becomes reachable rather than merely visible. The full weak-versus-strong prescription for this stem’s element is mapped in favorable elements for Metal Day Masters.
The trap is trying to fell the entire forest by effort alone. A Confined blade that keeps swinging without support does not get richer, it gets blunt. The five-element logic behind all of this is worth holding steady in mind; the five elements in Ba Zi explain why the season you control is also the season that drains you.
Three spring months, three different forests
The wealth of the season is not evenly spread across its three branches. The first month, 寅 Yín (Tiger), hides Jiǎ 甲, Bǐng 丙 and Wù 戊: Jiǎ is Geng’s Indirect Wealth 偏财, but the buried Bǐng is Seven Killings 七杀 — an early-spring blade meets pressure hiding inside its timber. The middle month, 卯 Mǎo (Rabbit), hides only Yǐ 乙, Geng’s Direct Wealth 正财 — the purest, most single-minded wealth month of the year, and the one where the Confined drain runs most steadily. The last month, 辰 Chén (Dragon), hides Wù 戊, Yǐ 乙 and Guǐ 癸, and it belongs to the transitional Earth branches 辰未戌丑, where Earth strengthens at each season’s end. Since Earth produces Metal, a Dragon-month Geng carries quiet resource inside its own month branch, and the late-spring reading is noticeably sturdier than the season core suggests.
The caveats that change everything
Season is only half of the strength verdict. It sets the baseline, but roots, hidden stems and the balance of the other pillars finish the judgement. A Geng born in spring but sitting on a Metal root, backed by Earth, and reinforced by companion stems can read as perfectly strong despite the Confined season. Another Geng in the same season with no root and heavy Wood and Water around it reads as genuinely overwhelmed. The season tells you the weather, not the whole terrain.
This is why the full strength assessment matters more than any single label. Work through the method in strong versus weak Day Master, and read the raw-blade temperament in depth on the Geng Metal Day Master profile. For contrast, a Geng born into its own metal season reads completely differently; compare the abundant, outlet-hungry Geng Metal born in autumn to feel how much the season shifts. The other two quarters bracket the picture from opposite sides: Geng Metal born in summer puts the blade under Fire’s direct control at the weakest baseline, while Geng Metal born in winter drains it gently through its own output — three different kinds of hard season, each asking for different support.
If you think you are geng metal born in spring, confirm both halves before you commit to the reading: that your Day Master truly is Gēng, and that your birth moment falls inside the Wood season by solar term rather than by the calendar. Plot the full chart with the Butcher Boy calculator and let the roots and hidden stems, not the season alone, settle how strong your blade really is.
