Chinese relationship comparison

Chinese zodiac and BaZi compatibility

Compare Chinese year animals and five-phase relationships, or use both sets of Four Pillars. Choose the calendar boundary and day clock before reading the result.

Year boundaryBaZi day boundary Apparent solar clock for BaZi day and hour

BaZi year and month use the exact solar-term instant. Day and hour use the chosen local or apparent solar clock. Chinese New Year changes the lunar-year animal on its calendar date.

Example: Horse and Monkey

No named two-branch combination, clash, harm or break joins these animal signs.

Four Pillars comparison

Year and month follow solar terms. The day stem is the Day Master; hour is withheld when its time is unknown.

Person	Pillar	Stem–branch	Phase	Animal
Person 1	Year	庚午	Metal	Horse
Person 1	Month	辛巳	Metal	Snake
Person 1	Day	庚辰	Metal	Dragon
Person 1	Hour	辛巳	Metal	Snake
Person 2	Year	壬申	Water	Monkey
Person 2	Month	戊申	Earth	Monkey
Person 2	Day	戊辰	Earth	Dragon
Person 2	Hour	辛酉	Metal	Rooster

Day Masters: Person 1 Geng Metal; Person 2 Wu Earth. Earth generates Metal.

Animal relation finder

Each row compares Horse with one of the twelve animals. A shared three-harmony group has three members; the two-person year comparison shows membership rather than a complete group.

Other animal	Relations with Horse
	Six Clashes
	Six Harms
	Three-harmony group
	Six Destructions
	No named relation
	Seasonal meeting
	Same branch · Self-punishment branch
	Six Harmonies · Seasonal meeting
	No named relation

	Three-harmony group
	No named relation

The animal rows use the named Chinese branch relations. The classical two-branch combinations, three-branch groups, harms, punishments and clashes are discussed in San Ming Tong Hui, volume 2. A year pair shows one relation; a complete BaZi reading compares all available pillars.

Three-harmony groups

Rat–Dragon–Monkey: Water · Rabbit–Goat–Pig: Wood · Tiger–Horse–Dog: Fire · Ox–Snake–Rooster: Metal.

Six harmonies

Rat–Ox · Tiger–Pig · Rabbit–Dog · Dragon–Rooster · Snake–Monkey · Horse–Goat.

Six clashes

Rat–Horse · Ox–Goat · Tiger–Monkey · Rabbit–Rooster · Dragon–Dog · Snake–Pig.

Five-phase comparison

Person 1 phasePerson 2 phase

Wood generates Fire.

Generating: Wood → Fire → Earth → Metal → Water → Wood. Controlling: Wood → Earth → Water → Fire → Metal → Wood. Year-stem and Day Master phases describe different chart positions.

All twenty-five phase pairs
First / second	Wood	Fire	Earth	Metal	Water
Wood	Same phase	Wood generates Fire	Wood controls Earth	Metal controls Wood	Water generates Wood
Fire	Wood generates Fire	Same phase	Fire generates Earth	Fire controls Metal	Water controls Fire
Earth	Wood controls Earth	Fire generates Earth	Same phase	Earth generates Metal	Earth controls Water
Metal	Metal controls Wood	Fire controls Metal	Earth generates Metal	Same phase	Metal generates Water
Water	Water generates Wood	Water controls Fire	Earth controls Water	Metal generates Water	Same phase

For example, a Wood year stem and a Fire year stem form the generating relation Wood → Fire. A Wood Day Master compared with Earth forms the controlling relation Wood → Earth. Keep the pillar role alongside its phase; generation and control name cycle relations rather than a personal compatibility percentage.

New Year dates: Hong Kong Observatory calendars. Li Chun and solar-month boundaries use the solar-term instant.
