Chinese Zodiac Relationship Compatibility: Trines and Clashes

The geometry behind the affinity triangles and clash pairs, the three layers most compatibility charts leave out, and how to hold the result.

Chinese Zodiac Relationship Compatibility: Trines and Clashes

Chinese zodiac compatibility is usually met as a list: these animals go well
together, those two should avoid each other. Underneath the list is a geometry, and
once you can see it the pairings stop being arbitrary — they come from where the
animals sit in a twelve-position cycle, in a way that will look immediately familiar
to anyone who reads a Western chart.

This describes the structure the groupings come from, the layers of the system
that popular compatibility charts leave out, and the register in which any of it is
worth holding.

The cycle underneath the pairings

Twelve animals run in a fixed order: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse,
Goat, Monkey, Rooster, Dog, Pig. Compatibility groupings are defined by the distance
between two animals in that sequence, which is the same principle as measuring an
angle between two points on a circle.

Because twelve positions divide a circle into thirty-degree steps, the traditional
groupings map onto familiar geometry. Animals four apart are 120 degrees apart —
what Western astrology calls a trine. Animals six apart
are 180 degrees apart, an opposition. The two systems developed independently and
describe different things, but both found the same divisions of a circle
interesting, which is worth noticing before treating either as arbitrary.

The four affinity groups

The best known grouping puts the animals into four sets of three, each set spaced
evenly around the cycle. These are the san he or three harmonies, often
rendered in English as the compatibility triangles.

The third column is a summary of how the groups are conventionally characterised,
not a definition — descriptions vary between sources and between the popular and
the traditional literature. If a triangle looks like a
grand trine to you, that is the same geometry appearing
in a different tradition rather than a borrowing.

The clashes and the harmonies

Two more groupings account for most of what compatibility charts report.

The six clashes

Animals directly opposite each other in the cycle — six apart — form the
liu chong or six clashes: Rat and Horse, Ox and Goat, Tiger and Monkey,
Rabbit and Rooster, Dragon and Dog, Snake and Pig. These are conventionally read as
the pairs with the most friction.

Note what that framing does and does not say. In Western practice an opposition
between two charts is not read as a verdict either; it describes a polarity that
has to be worked with rather than a relationship that cannot exist. The Chinese
material is generally read the same way by practitioners, whatever the popular
compatibility charts imply.

The six harmonies

A separate set of six pairs, the liu he, is read as mutually supportive:
Rat and Ox, Tiger and Pig, Rabbit and Dog, Dragon and Rooster, Snake and Monkey,
Horse and Goat. These pairings do not follow the even spacing of the triangles, and
several accounts of where they come from exist in the literature.

Further groupings — variously translated as harms, destructions and punishments —
appear in some traditions and not others, and are the layer where sources diverge
most. Any short compatibility chart has already selected which of these to show
you.

The layer most compatibility charts skip

This is the part worth knowing before putting weight on a result. The year animal
is one of four components in the full system.

Traditional Chinese astrology works with four pillars — year, month, day and hour —
each carrying an animal and an element. In that framework the day
pillar, not the year, is generally taken to represent the person, and the year
pillar is read as the outer or generational layer. Compatibility assessed from year
animals alone is therefore a summary of one quarter of the picture, and the
practitioners who use the full system say so plainly.

The parallel in Western practice is exact: comparing two Sun signs is not
synastry, and the difference between the two is the same
difference. A single factor can be interesting; it is not the reading.

Two dates that change your animal

Before you look anything up, check which animal you actually have, because there
is a real disagreement about where a year begins.

One convention starts the animal year at Chinese New Year, which falls on a
different date each year between late January and late February. Another starts it
at Lichun, the solar term marking the beginning of spring, which lands
around the fourth of February. The two dates are usually a few weeks apart.

For anyone born in January or the first part of February, the two conventions can
give different animals. Neither is a mistake — they are different reckonings, one
lunisolar and one solar, and the four-pillars tradition generally uses the solar
one. Find out which your source applies before drawing conclusions from it.

The five elements sit on top

Each year also carries one of five elements — wood, fire, earth, metal, water —
cycling so that a given animal and element combination recurs every sixty years.
Compatibility accounts often add an element layer, since the five elements have
their own generating and controlling relationships.

These are not the four Western elements with an extra one
added. The two schemes have different members, different logics and different
purposes, and mapping one onto the other is a habit that produces confident
nonsense in both directions.

How to hold a compatibility reading

Two things make this material useful rather than corrosive.

The first is remembering what a symbolic system can do. A grouping describes a
pattern that two people might recognise; it cannot tell you whether a relationship
will work, and no arrangement of animals is a reason to begin or end one. That is a
matter of how two people actually treat each other, which no cycle can see.

The second is the direction you read it in. A clash pairing that describes
something you have already noticed is informative. A clash pairing you learn about
first and then start looking for is a good way to manufacture evidence. The same
caution applies to orb figures, to
composite charts, and to
chart reading generally — the description is worth something
when it meets recognition, and worth very little when it precedes it.

Frequently Asked Questions

How does Chinese zodiac compatibility work?

It is based on the distance between two animals in the twelve-position cycle. Animals four apart form the affinity triangles, animals directly opposite form the six clashes, and a separate set of six pairs forms the harmonies. Because twelve positions divide a circle into thirty-degree steps, these groupings correspond to the trine and opposition angles familiar from Western astrology.

What are the four Chinese zodiac compatibility triangles?

Rat, Dragon and Monkey; Ox, Snake and Rooster; Tiger, Horse and Dog; and Rabbit, Goat and Pig. Each set contains animals spaced four positions apart, so they sit evenly around the cycle. They are known as the san he or three harmonies, and how each group is characterised varies between sources.

Which Chinese zodiac animals clash?

The six clash pairs are animals directly opposite each other in the cycle: Rat and Horse, Ox and Goat, Tiger and Monkey, Rabbit and Rooster, Dragon and Dog, Snake and Pig. Practitioners generally read a clash as a polarity requiring work rather than as a verdict on a relationship, in the same way an opposition is read in Western practice.

Is the year animal enough for a compatibility reading?

Not in the traditional system. Chinese astrology uses four pillars — year, month, day and hour — and the day pillar is usually taken to represent the person, with the year read as the outer or generational layer. Compatibility from year animals alone covers roughly a quarter of the picture, much as comparing two Sun signs is not the same as synastry.

When does a Chinese zodiac year actually begin?

There are two conventions. One starts the animal year at Chinese New Year, which falls between late January and late February depending on the year. The other starts it at Lichun, the solar term for the beginning of spring, around the fourth of February. Anyone born in January or early February may have a different animal under each, and the four-pillars tradition generally uses the solar reckoning.

Are the five Chinese elements the same as the four Western ones?

No. The Chinese system uses wood, fire, earth, metal and water with their own generating and controlling relationships; the Western system uses fire, earth, air and water for a different purpose. They share two names and very little else, and treating one as an extended version of the other produces confusion in both directions.
