Sin-yu is Metal on Metal: 辛, the Jewel, on 酉, the Rooster, which is pure refined yin Metal and nothing else. It is a 간여지동 pillar, stem and branch of the same element, and 酉 is Sin's peak-strength (건록) branch. Picture a single cut gem in a jeweler's case, lit from above, every facet clean. No setting, no distraction. Just the stone.
You are confident, discerning and independent. You have a clear sense of who you are and what you will not tolerate. You notice quality instantly, and you notice flaws just as fast, in products, plans and people. The Di Tian Sui calls Sin soft, warm and clear, and you are softer than your reputation: you simply protect it with standards. The classical lesson for such pure Metal is that it needs Water to show its shine and a little Fire to refine it. Without them, Sin-yu can become rigid, critical and lonely in a beautifully curated way.

Sin-yu in love
Your spouse palace holds your own element as Friend (비견), so you want an equal: someone as self-possessed and particular as you. You are selective, and when you choose, you are loyal and steady. You show love through quality time and thoughtful details.
You can also be hard to please, competitive and quietly critical. You may hold a partner to standards you would never say out loud. Choose someone secure and warm, ideally with Water energy, who expresses feelings easily and helps you express yours. Let them see a scratch or two. It makes you more lovable, not less.
As a friend
You are the discerning friend whose recommendation actually means something. You are loyal to a few people and honest with all of them. You can come across as judgmental, especially about taste. Your friends know that if you say something is good, it is very good, and that you will show up when it matters.
Red flags
- You hold partners to standards you never told them about.
- You compete with people you are supposed to be cheering for.
- You hide insecurity behind perfect presentation.
- You refuse help because accepting it feels like a flaw.
YeonNobody is flawless, including you. Let someone see a scratch. That is where the light gets in.
At work
Sin-yu thrives in precision fields: jewelry and design, finance, quality control, law, editing, research, luxury brands. You produce polished work and you raise everyone's standards. Your growth area is flexibility. Not every draft needs to be flawless before anyone sees it.
Sin-yu vs the other Sin Metal pillars
Sin-yu is the purest and most self-assured of the Sin pillars. Sin-myo (辛卯), its clash partner (卯酉), is playful and pleasure-loving where you are exacting. Sin-sa (辛巳) is poised and principled, drawn to a partner it can admire. Sin-hae (辛亥) is witty and rebellious. Sin-mi (辛未) and Sin-chuk (辛丑) sit on Resource Earth and live more inwardly. Only you sit on pure Metal with a peer in the spouse palace, which is why you want an equal partner and why your standards are the highest in the family.
Chart notes
Chart notes for Sin-yu: the 酉 Rooster branch is Metal and hides 庚 (Rob Wealth), 辛 (Friend), read from a Sin Metal point of view. Its main qi, 辛, puts Friend (비견 比肩) in the Sin-yu spouse palace. In branch relations, 酉 clashes with 卯 (Rabbit) and forms a six-harmony pair (육합) with 辰 (Dragon), so a partner with a Rabbit or Dragon day branch will feel noticeably different to a Sin-yu person. 辛酉 is pillar 58 of the sixty in the 육십갑자 cycle.
