What Is Sangcheonsal (相穿殺)? — A Branch Relationship Nobody Explains Well

Sangcheonsal (相穿殺) is a name attached to a relationship between two Earthly Branches (地支) read as "piercing" or "boring through" each other. It's usually treated as the same thing as Haesal (害殺), the Six Harms — 穿 ("to pierce") is really just another way of naming 害 ("to harm"). It doesn't collide as head-on as a clash (沖), but it's read as the kind of quiet friction that can crop up between people who are otherwise close. It's rarely explained well, since it's one of the lesser-known branches among the many relationships between Earthly Branches. Worth saying up front: it's a reference clue, not a fixed fate.

Which characters form Sangcheonsal?

Sangcheonsal (= the Six Harms) forms between six fixed pairs of Earthly Branches.

• Rat–Goat (子未)
• Ox–Horse (丑午)
• Tiger–Snake (寅巳)
• Rabbit–Dragon (卯辰)
• Monkey–Pig (申亥)
• Rooster–Dog (酉戌)

These six pairs aren't arbitrary — they follow from a rule. When one branch clashes (沖) the partner that another branch would form a Six Combination (六合) with, those two branches end up "piercing" each other. For example, Rat (子) combines with Ox (丑); the branch that clashes with Ox is Goat (未) — which is why Rat–Goat becomes a Sangcheon pair. The other five pairs are derived the same way. Gwiraedang also calculates these six Harm relationships deterministically in code, marking them on the results screen's natal-chart relationship list (labeled, for instance, "Rat-Goat Harm") and noting which positions carry them under the "Six Harms (Sangcheonsal)" label in the sinsal table.

How has Sangcheonsal traditionally been read?

In traditional myeongli, Sangcheon (Harm) has been read as a clue pointing to quiet friction, hurt feelings, or a subtle rift between people who are close. If a clash (沖) is a head-on collision that shakes things up, Sangcheon is usually described as weaker but more persistently nagging. Older readings sometimes connected it to family relationships (六親) or to health as well.

Schools do differ here, though. Most treat 穿 and 害 as effectively the same thing, but some draw a fine distinction between the two, and others don't weight Sangcheonsal heavily at all. Some readers treat it as a meaningful interpretive clue; others center the basic grammar of the branches — clashes and combinations — and use Sangcheon only as a supporting ingredient. So the honest approach is to treat it as one clue among several, rather than using it alone to make a verdict about a relationship or a body.

Is it bad to have Sangcheonsal?

The name carries "-sal (殺)," which sounds frightening, but there's no need to be scared. Like other sinsal, Sangcheonsal isn't a stamp of fortune or misfortune stamped in advance — it's closer to a nickname attached to a specific combination of characters. If it signals that a close relationship runs the risk of a little friction, that can just as easily be read as "this relationship is worth a second look and a little extra care." And if a frightening diagnosis is followed by a talisman or an expensive remedy, it's worth stepping back and asking whether that fear is just the raw material for a sales pitch.

Even the same characters play out differently depending on which Gungwi palace position they fall in and how the whole chart balances out. Sangcheonsal isn't the main reading of a chart — it's a supporting clue that adds color, not something that defines a person on its own.

Sangcheonsal in a Saju chart isn't a fortune that predicts a fixed misfortune — it's a reference clue for reflecting on your relationships. What to adjust, and how to live with it, is ultimately up to you, not the characters.
