Korean Zodiac Compatibility: Samhap, Yukhap, Chung and Wonjin

Korean zodiac compatibility rests on four classic relationships between the twelve animals. Samhap (삼합 三合) and yukhap (육합 六合) are the harmonious links. Chung (충 沖) marks direct opposites. Wonjin (원진 怨嗔) is a “resentment” pair that is especially popular in Korean talk. Find your animal in the tables below and you can see every link at a glance.

Keep one thing in mind from the start. In saju (사주 四柱, the Korean four-pillar chart) these relationships are symbols for how energies mix. They are not verdicts on a relationship. A “clash” pair can be a lively, loving couple, and a “harmony” pair still has to do the dishes.

How the twelve animals are arranged

The zodiac animals are the twelve earthly branches, or jiji (지지 地支). Picture them as a clock face: Rat 子 at the top, then Ox 丑, Tiger 寅, Rabbit 卯, Dragon 辰, Snake 巳, Horse 午, Goat 未, Monkey 申, Rooster 酉, Dog 戌 and Pig 亥 going around. Each has an element, and most compatibility rules are really about geometry on that clock:

• Samhap: animals four steps apart, forming a triangle
• Chung: animals six steps apart, directly across the clock
• Yukhap: pairs that mirror each other across a line on the clock
• Wonjin: each animal with the neighbour of its opposite

Samhap: the three harmonies

Samhap (삼합 三合, “three combining”) groups the twelve animals into four triangles. Each trio is traditionally read as sharing one element and one direction of energy. It is often the first thing people check.

In saju symbolism, samhap partners “pull in the same direction,” a bit like friends who share a goal. Two members of a trio already count as a partial harmony. All three together, for example in a family or a group chat, are seen as a complete set.

Yukhap: the six pairs

Yukhap (육합 六合, “six combining”) pairs each animal with exactly one partner. It is read as a quieter, one-to-one bond, closer to “we just click” than “we share a mission.”

Chung: the six clashes

Chung (충 沖, “clash”) links animals that sit directly opposite each other. Their elements usually pull in opposite directions: water against fire, wood against metal, and earth against earth across the seasons.

A clash is traditionally read as movement, contrast and friction. Many practitioners point out that friction can be energizing. Opposite pairs often cover each other’s blind spots. The practical takeaway is “talk things through,” not “stay away.”

Wonjin: the resentment pairs

Wonjin (원진 怨嗔, roughly “resentment and irritation”) is especially popular in Korea. It is the one you will hear older relatives mention. Each animal is paired with a neighbour of its opposite. Folk explanations say the pair gets on each other’s nerves over small things, even when nothing is really wrong.

The friendliest way to read wonjin: notice the little irritations early and name them kindly. That advice works for anyone.

A quick worked example

Say a Horse and a Goat are dating, and the Goat’s best friend is a Rat. Check the chart row by row:

• Horse + Goat: a yukhap pair, the classic “we just click” bond.
• Goat + Rat: a wonjin pair. The folk image is small irritations, so these two might bicker about plans or punctuality.
• Horse + Rat: a chung, direct opposites. Expect lively debates.

Read symbolically, this trio has one easy bond and two spicy ones. That makes it a very normal friend circle. The useful question is not “who should go?” but “who smooths things over when the Rat and the Horse start arguing?” In this story, probably the Goat.

Why the year animal is only the beginning

Year-animal compatibility is the quick, party-game version. In a full saju chart every pillar has a branch: year, month, day and hour. So two people’s charts can hold several links at once. You might clash by year animal and harmonize by day branch.

Practitioners doing a full compatibility reading, called gunghap (궁합 宮合) in Korean, usually look further:

• Day masters (일간 ilgan): how each person’s day stem relates through the five-element cycles
• Element balance: whether one chart supplies what the other lacks
• Branch links across all pillars, not just the year

A Korea Herald report on gunghap quoted a longtime Seoul practitioner who said the point is not to tell couples whether to marry. It is to show how two people differ, so they can put in effort where it counts. That is the spirit SajuBunny follows too.

FAQ

Which Korean zodiac signs are most compatible?

In the classic rules, the best-known harmonies are the samhap trios (Monkey-Rat-Dragon, Tiger-Horse-Dog, Snake-Rooster-Ox, Pig-Rabbit-Goat) and the six yukhap pairs, such as Rat-Ox or Horse-Goat. These are traditionally read as easy cooperation. They are symbols, though. Real compatibility depends on the people, and a full chart holds many more links than the year animal.

What is wonjin in Korean compatibility?

Wonjin, written 怨嗔, is a set of six “resentment” pairs, such as Rat-Goat and Tiger-Rooster. It is especially well known in Korea. Folk tradition reads it as a tendency toward small irritations. A kinder, more useful reading is to spot minor frictions early and talk about them, which helps any relationship, whatever the animals.

Does a chung clash mean a relationship will fail?

No. Chung simply marks animals that sit opposite each other in the twelve branches, such as Rat and Horse. In saju symbolism it stands for contrast and movement. Many clash pairs balance each other well. SajuBunny treats compatibility as a conversation starter, never as a reason to end or avoid a relationship.

Should I use year animals or the full chart?

Year animals make a fun, quick check, and they are what most people mean in casual Korean talk. A full saju reading also compares day masters, element balance and branch links across all four pillars. Since the year animal is one of eight characters, the full chart gives a much richer, more personal picture of how two people fit together.
