Chinese zodiac compatibility for the Pig maps to exactly three labels under the limited two-rule model used by the Chinese Zodiac Compatibility browser: Traditional trine (San He), Direct opposition (Liu Chong), and Not classified by this limited two-rule model. The Pig belongs to the fourth and final San He trine, which groups Rabbit, Goat, and Pig, so it shares a trine with the Rabbit and the Goat. Its single direct Liu Chong opposition is the Snake, which is the only one of the six canonical oppositions that involves the Pig. The remaining eight pairings — Rat, Ox, Tiger, Dragon, Horse, Monkey, Rooster, and Dog — fall outside both rules and are reported as unclassified, a label that intentionally does not mean neutral, safe, ideal, or doomed. The browser never converts a Gregorian year into an animal, never assigns a percentage or score, and never extends the two sourced rules into a universal compatibility table. The 11 partners are read in the canonical order Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and the result is symmetric, so swapping the two selectors changes only the display order.
How the two-rule browser labels Pig pairs
The browser keeps its scope deliberately narrow. It evaluates only the pair of animals the user chooses and reports one of three labels drawn from the sourced classification. A pair inside the same three-member trine as the Pig is labelled Traditional trine (San He). A pair that matches one of the six canonical oppositions is labelled Direct opposition (Liu Chong). Every other pair is labelled Not classified by this limited two-rule model. The label is the only result, and it is the same label the page will show if the user picks the same two animals again tomorrow. The browser is not a personality quiz, does not weight the two rules against each other, and does not perform a Gregorian year lookup. The Pig's identity, like every other animal, is supplied by the user through a native selector with a 44-pixel minimum height, and the partner animal is chosen the same way. A second control, Swap, exchanges the two values in one action and the result updates immediately from the same pure classifier, which is what makes the symmetry checkable on screen.
Pig's trine partners: Rabbit and Goat
The fourth San He trine in the canonical reference data is the literal group Rabbit, Goat, and Pig. Any two distinct members of that group receive the label Traditional trine (San He), so the Pig is trine with both the Rabbit and the Goat. That gives the Pig exactly two trine partners out of 11 possible pairings, which is the maximum the structure of the trine rules allows because each of the three members of a trine is paired with the other two, producing 3 unordered pairs per trine and 12 unordered trine pairs across all four trines. The trine label is symmetric: choosing Pig as the first animal and Rabbit as the second shows the same label as Rabbit first and Pig second, and the same is true for the Pig–Goat ordering. The Pig is not trine with Rat, Ox, Tiger, Dragon, Snake, Horse, Monkey, Rooster, or Dog under this rule, because each of those animals belongs to a different trine. The Pig's profile block on the result page shows the full fourth trine (Rabbit, Goat, Pig) so the trine label is verifiable without trusting an unexplained badge.
The Pig's direct opposition: Snake
The six direct Liu Chong oppositions in the reference data are Rat with Horse, Ox with Goat, Tiger with Monkey, Rabbit with Rooster, Dragon with Dog, and Snake with Pig. The Snake is the only one of the six oppositions that involves the Pig, and the Pig is the only animal on the other side of the Snake. Choosing Pig and Snake therefore shows the label Direct opposition (Liu Chong) and nothing else. The opposition label is symmetric, so Snake first and Pig second returns the same label. The opposition set is fixed and complete: the Pig has exactly one direct opposite in this model, and it is the Snake. To verify the rule on screen, the user can open the result with Pig and Snake selected and then tap Swap; the displayed label does not change, and the Pig's profile block continues to show Snake as its direct opposite while the Snake's profile block shows Pig as its direct opposite.
The eight unclassified Pig pairs
Eight of the 11 possible Pig pairings sit outside both the trine rule and the opposition rule. The full list, in the canonical interface order, is Rat, Ox, Tiger, Dragon, Horse, Monkey, Rooster, and Dog. Each of those pairings is labelled Not classified by this limited two-rule model. The label is an honest description of what the two rules cover, not a verdict on whether the pairing is workable, harmonious, or doomed. The Pig's eight unclassified pairs are part of the 48 unclassified unordered pairs the browser verifies across the full 12-animal cycle under the same two rules. Readers can see all 48 of those unclassified pairs collected in one place through the Chinese Zodiac Compatibility: The 48 Unclassified Pairs reference. The classification is symmetric in every case, so swapping Pig with any of these eight animals shows the same unclassified label. Each of those eight unclassified pairings is a candidate for further research using traditions the browser does not cover, such as Six Harmonies, harm relationships, Five Elements, or full Four Pillars analysis.

How to look up any Pig pairing
For readers who want to confirm any of the 11 pairings, the browser handles the lookup in a few simple steps. No date, year, name, account, location, cookie, or local storage is required, and the two selections stay in browser state only.
- Open the Chinese Zodiac Compatibility browser directly. Do not look for a year or date field; the tool does not derive an animal from a Gregorian year.
- In the first selector, choose Pig from the canonical list of 12 animals. The list is in the order Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig.
- In the second selector, choose the partner animal you want to compare with Pig, such as Rabbit for a trine check, Snake for the opposition check, or Rat for an unclassified check.
- Read the label that appears in the result block. It will be exactly one of Traditional trine (San He), Direct opposition (Liu Chong), or Not classified by this limited two-rule model.
- Inspect the two profile blocks to see each selected animal's full trine group and direct opposite. This makes the result checkable without trusting an unexplained badge.
- Tap Swap to exchange Pig and the partner. The label will not change, which confirms the classification is symmetric.
- Close or refresh the page when you are done. The two selections are kept only in React page state and are not saved, transmitted, or stored.
What this limited model does not claim
Reading the source list carefully helps avoid two common misreadings. The first is to treat the unclassified label as a verdict at all: the tool never says "neutral," "compatible," "incompatible," "safe," or "doomed," and the design choice is to spell out what the model does not cover rather than imply a hidden ranking. The second is to assume that year-animal compatibility is a complete substitute for a full BaZi / Four Pillars analysis, which can also consider the month, day, and hour branches along with the year branch and may add further named relationships that fall outside the two rules this browser applies. Cultural context also matters: English sources sometimes use Mouse for Rat, Cow for Ox, and Sheep or Ram for Goat, and the browser uses the canonical labels Rat, Ox, and Goat so the results line up with its own fixtures. Regional substitutes such as Cat or Boar are treated as out of scope because they would need a separately declared cultural source list, as confirmed by overview references such as the TravelChinaGuide Chinese zodiac compatibility overview. For readers who want to start with a Gregorian year before doing any pair check, the related Chinese Zodiac Calculator maps a supported year to the conventional animal cycle and flags the Lunar New Year boundary that the pair browser deliberately ignores.
