Your Day Master (日主 rìzhǔ) is Xīn 辛 — Yin Metal: the finished jewel — refined, exacting, quality over quantity in everything from work to friendships. Xīn has already been through the fire once; what remains is precise, polished, and quietly expensive. The gift is standards no one else will hold. The shadow is the armour of polish: criticism lands harder than it should, and perfection becomes a place to hide.

The Xīn temperament
In the five-element mechanics, Xīn is fed by Earth, expresses itself through Water, treats Wood as its wealth, and answers to Fire as pressure and authority. Those four arrows explain most of what this stem loves and avoids: seasons, people and jobs are experienced as more or less of each.
In charts we read Xīn as the connoisseur stem — the one that notices. The crooked picture frame, the imprecise word, the small dishonesty in a deal everyone else waved through: Xīn registers all of it, usually silently. Where Gēng meets pressure by hardening, Xīn meets it by refusing to be handled roughly at all; the jewel does not fight the hammer, it simply remembers who swung it. That long, elegant memory is Xīn’s real weapon and its real burden. The stem also has the sharpest tongue of the ten when it finally speaks — Water, its output, turns observation into the exact cutting sentence — which is why the disciplined Xīn edits twice and the undisciplined one loses friends in single lines.
In relationships Xīn is selective and, once committed, meticulous: the partner who remembers the anniversary, the allergy, the offhand wish from March. It asks to be valued accurately — not flattered, valued — and quietly grades whether it is.
Xīn through the four seasons
Season sets the jewel’s setting. The classical grades are 旺 wàng (Prosperous), 相 xiàng (Supported), 休 xiū (Resting), 囚 qiú (Confined) and 死 sǐ (Dormant) — solar-term seasons, not calendar months, with the Earth branches 辰未戌丑 shading toward Earth at each season’s end.
| Season | Branches | Dates | Xīn’s state |
|---|---|---|---|
| Xīn born in spring | 寅卯辰 | Feb 4 – May 4 | 囚 qiú — Confined |
| Xīn born in summer | 巳午未 | May 5 – Aug 6 | 死 sǐ — Dormant |
| Xīn born in autumn | 申酉戌 | Aug 7 – Nov 6 | 旺 wàng — Prosperous |
| Xīn born in winter | 亥子丑 | Nov 7 – Feb 3 | 休 xiū — Resting |
In spring, Metal stands over the Wood it controls — a wealth season, but fighting uphill against the times: effortful, gritty. In summer, Fire controls Metal: the weakest baseline, where support and timing matter more than effort — hard weather for a fine finish. Autumn is Metal’s own season: maximum native strength; the chart usually needs outlets, not more support. In winter the jewel feeds the season’s Water — energy flows out, a mild drain, the retired-general state. Each season page reads one setting in detail.
Career and money
Where discernment is the product: luxury and brand, finance and valuation, curation, diagnostics, editing, quality anything. Wood is the wealth element — growing things appraised and cultivated; Xīn money comes from knowing what a thing is truly worth before others do.
Strong Xīn, weak Xīn
A strong Xīn should be priced, not busy: fewer clients, finer work, Water (expression, output) to keep brilliance from turning brittle. A weak Xīn needs Earth’s setting — institutions, patrons, protective structure — because a loose gem gets pocketed by whoever finds it.
Not sure which you are? Season is half the verdict — see strong vs weak, properly judged, then favorable elements for Metal Day Masters for the working consequences.
Your six Xīn day pillars
Xīn sits on one of six day branches; the pair — the day pillar (日柱 rìzhù) — is the unit we actually read. As a yin stem, Xīn pairs with: Xīn Chǒu 辛丑, the gem in the winter vault; Xīn Mǎo 辛卯, the jewel among spring growth; Xīn Sì 辛巳, the jewel in the kiln fire; Xīn Wèi 辛未, the gem in warm dry soil; Xīn Yǒu 辛酉, polished metal on its own ground; and Xīn Hài 辛亥, the jewel washed in clear water. Because the day branch is also the spouse palace, these six diverge most in relationship readings — each page takes one apart.
The Ten Gods for a Xīn Day Master
Relative to Xīn, every stem in the chart becomes one of the Ten Gods (十神 shíshén). For Yin Metal the polarity places Bǐng, the sun, as the flattering Direct Officer and Dīng, the smith’s flame, as the dangerous Seven Killings — jewels enjoy sunlight and fear the crucible. Full interpretation in the Ten Gods for Xīn Metal.
| Stem | Ten God for Xīn |
|---|---|
| Jiǎ 甲 (Yang Wood) | Direct Wealth 正财 |
| Yǐ 乙 (Yin Wood) | Indirect Wealth 偏财 |
| Bǐng 丙 (Yang Fire) | Direct Officer 正官 |
| Dīng 丁 (Yin Fire) | Seven Killings 七杀 |
| Wù 戊 (Yang Earth) | Direct Resource 正印 |
| Jǐ 己 (Yin Earth) | Indirect Resource 偏印 |
| Gēng 庚 (Yang Metal) | Rob Wealth 劫财 |
| Xīn 辛 (Yin Metal) | Friend 比肩 |
| Rén 壬 (Yang Water) | Hurting Officer 伤官 |
| Guǐ 癸 (Yin Water) | Eating God 食神 |
Xīn in 2026 — the Bǐng Wǔ year
2026’s heavy Fire presses hardest on Yin Metal — visibility with heat: scrutiny, competition for the polished position, tempers around precision work. The strong Xīn treats it as hallmarking — public proof under pressure. The weak Xīn protects the finish: fewer exposures, chosen carefully, and no arguing with bonfires.
