Xin 辛, the Yin Metal Day Master

Jewel, moonlight or ore? Three pictures of 辛

辛 is the eighth stem, the yin half of the metal pair; its yang counterpart is 庚. In Korean it is 신금 (Sin-geum), or 신금 일간 when it is your Day Master. Three classical descriptions of it circulate, and they don’t match.

The jewel reading does have a source: 三命通會’s fourth volume lists mercury, cinnabar and pearls (vol. 4). The moon reading is the most specific. The same book’s second volume has 辛 at its brightest in mid-autumn, when “metal and water are in balance” and the light is “round and clear,” and quotes 邵子 (Master Shao): “on the fifteenth of the eighth month, enjoy the moon” (vol. 2). The 滴天髓 commentary goes the other way and strips the ornaments off: 辛 is yin metal, “not a term for pearls and jade,” simply gentle, warm and clear (滴天髓).

What the three share matters more than which wins. None of them makes 辛 blunt or hard (the second volume says outright that it is not 頑鈍堅剛, “dull and hard”), all of them have it show best when it is clean, and it is easily covered. Personality readings that stress taste, precision and sensitivity build on that shared core, not on the jewelry box.

Why 辛 “fears piled earth and delights in water”

The 滴天髓 verse for 辛: “辛 metal is soft and yielding, warm, smooth and clear. It fears earth piled up and delights in water in plenty. It can prop up the state and rescue living things. In heat it welcomes its mother; in cold it welcomes 丁.” The commentary explains the middle couplet plainly: much 戊 earth buries 辛, and much 壬 water makes it fine (秀) (滴天髓).

Mapped onto the ten gods, those lines become a habit sketch. Earth is 辛’s resource family: 戊, your Direct Resource, and 己, your Indirect Resource. Too much of it is the picture of being buried in preparation, support and other people’s advice. Water is 辛’s output: 壬, your Hurting Officer, and 癸, your Eating God, the tradition’s names for expression, making and saying. As a habit, the verse’s advice is to let the work out: send the draft, say the opinion, rinse off the polish.

三命通會 tells the same story through the twelve stages. It has 辛 “born at 子,” where the water “washes away the loose sand so that its color shows,” and “dying at 巳,” where the furnace fire forges it into a dead vessel and the earth in 巳 buries it (vol. 2). The engine agrees: 辛 is at 長生 (“starting fresh”) in 子 and 死 (“quiet focus”) in 巳.

How a Xin Day Master tends to come across

As a temperament, 辛 tends to be exacting, observant and quietly proud: the person who notices the wrong font, remembers the exact wording of a compliment from years ago and keeps standards when nobody is checking. The sensitivity cuts both ways. A careless remark tends to stay with 辛 longer than with most people, and so does a kind one.

Where the yang metal is pictured as getting sharper under heat, 辛 tends to do its best work under care: clear expectations, a clean workspace, room to refine. The trap is waiting for those conditions before starting. The verse’s earth line makes a good mirror. If you catch yourself collecting one more reference, one more opinion, one more round of polish, that is the piled earth, and the tradition’s answer is water, not more metal.

The six 辛 day pillars

The six are 辛未 Metal Goat, 辛巳 Metal Snake, 辛卯 Metal Rabbit, 辛丑 Metal Ox, 辛亥 Metal Pig and 辛酉 Metal Rooster. They range from 辛酉 Metal Rooster, where 辛 sits at 建禄 (“steady self-reliance”) on its own branch, to 辛巳 Metal Snake, where it stands at 死. 三命通會’s verse for the six 辛 days begins with the first and ends with the second: “at 酉, sitting on its 祿, the strongest,” and “at 巳, it sits in a metal formation (金局), so death does no harm” (vol. 4). The handbook itself shrugs off the “death” here, and in our readings those names describe how a stem sits in a branch, never anyone’s health or lifespan.

The branches also explain why 辛 day pillars feel so different from each other. 辛卯 Metal Rabbit sits on nothing but Indirect Wealth; 辛亥’s branch holds 壬 Hurting Officer and 甲 Direct Wealth; 辛未 carries Indirect Resource, Seven Killings and Indirect Wealth under the surface.

Pairing: 丙 and 辛

辛’s stem-combination partner is 丙, your Direct Officer. 滴天髓 tells the combination from the other side: its lines for 丙, “fierce and blazing” fire (丙火猛烈), say it “can forge 庚 metal but turns timid on meeting 辛” (能煆庚金，逢辛反怯), and the commentary explains that 辛, though soft, combines with it and weakens it (滴天髓). The fire that forges iron is disarmed by the smaller metal, the same move the verses make with 庚 and 乙.

In a compatibility reading the stem combination is one line among many; the branches, the elements and the rest of both charts count as much. The free pair check puts two day pillars side by side and gives a badge, not a percentage.

2027 (丁未) for a 辛 Day Master: the texts disagree

For 辛, 丁未 is the year where the classics argue with each other. Its stem is 丁, your Seven Killings. 滴天髓 says a 辛 born in the cold “welcomes 丁,” which warms it (滴天髓); 三命通會’s fourth volume says 辛 is better off without 丁, “like a pearl dropped into a furnace” (vol. 4). Below it, 未 holds 己, your Indirect Resource, as its main stem, with 乙, your Indirect Wealth, beside it, and 辛 stands at 衰 (“experienced calm”) in 未.

We don’t pick a winner, because neither text is describing events. Read as habits, a Seven Killings stem tends to put a push from outside in the foreground, and an Indirect Resource branch tends to pull toward study, second opinions and thinking it over. The verse’s piled earth is the likely trap: meeting pressure by preparing more instead of by acting. Something small and finished tends to answer pressure better than something large and still being polished. That is a description of emphasis, not a forecast.
