Sin-hae places the Jewel on 亥, the Pig: deep winter Water with 甲 Wood and a little 戊 Earth inside. Metal produces Water, so this branch is Sin's output, the Hurting Officer (상관) here. It is also the image classical writers love most for Sin. The Qiong Tong Bao Jian keeps returning to 壬 Water washing the jewel clean (淘洗), and the main qi of 亥 is exactly 壬. Picture a gem lying in a mountain river in winter, the current polishing it until it flashes.
You are witty, articulate and independent. You see through pretense quickly and you describe it precisely, often in a way that makes people laugh and wince at once. Metal-and-Water charts (金水) are classically linked with intelligence and a striking, clean kind of attractiveness. Hurting Officer energy adds creativity and a rebellious streak; rules have to make sense to you or you ignore them. The caution is cold. Too much winter Water drains a small jewel, and without some Fire for warmth you can drift into sarcasm, detachment and a quiet loneliness you would never admit to.


BomYou see clearly and say it beautifully. People leave a conversation with you understanding something they could not put into words before.
Sin-hae in love
Hurting Officer in the spouse palace makes you a stimulating, independent partner. You want banter, depth and freedom. You fall for people who surprise you and you lose interest in people who only agree with you.
The shadow is criticism and restlessness. You can review a partner like a film, sharp and well argued, and forget they are a person with feelings. You may also push people away to prove you do not need anyone. You need someone warm, secure and smart: a partner with Fire energy who appreciates your mind and does not try to cage it.
As a friend
You are the friend with the best takes and the most honest feedback. Ask you about a haircut and you will tell the truth. You are loyal in a quiet, unsentimental way and you defend friends with words. You can be blunt and you need a lot of alone time. Your friends love your clarity and have learned that your sarcasm is usually affection in disguise.
Red flags
- You critique your partner like a book review.
- You get bored the minute things become calm.
- You hide every soft feeling behind sarcasm.
- You push people away to prove you do not need them.


YeonSarcasm is not a love language. Say the soft thing out loud. They will survive it and so will you.
At work
Sin-hae thrives in writing, design, law, media, research, tech and creative entrepreneurship. You are brilliant at critique and at seeing what everyone else missed. Choose roles with freedom and a clear purpose. Micromanagement makes you either rebel loudly or disengage quietly.
Sin-hae vs the other Sin Metal pillars
Sin-hae is the most expressive and rebellious Sin pillar. Sin-sa (辛巳), its clash partner (巳亥), sits in sunlight with an Officer in the spouse palace, poised and principled where you are irreverent. Sin-yu (辛酉) is pure Metal and self-assured but less verbal. Sin-myo (辛卯) is playful and social. Sin-mi (辛未) and Sin-chuk (辛丑) sit on Resource Earth and turn inward. You want a partner who can keep up with your wit; Sin-sa wants one with principles, and Sin-myo wants one who makes life fun.
Chart notes
Chart notes for Sin-hae: the 亥 Pig branch is Water and hides 戊 (Direct Resource), 甲 (Direct Wealth), 壬 (Hurting Officer), read from a Sin Metal point of view. Its main qi, 壬, puts Hurting Officer (상관 傷官) in the Sin-hae spouse palace. In branch relations, 亥 clashes with 巳 (Snake) and forms a six-harmony pair (육합) with 寅 (Tiger), so a partner with a Snake or Tiger day branch will feel noticeably different to a Sin-hae person. 辛亥 is pillar 48 of the sixty in the 육십갑자 cycle.
