Six Harmonies (六合)

In BaZi astrology, the Six Harmonies (Liu He) (六合) is one of the fundamental interactions between Earthly Branches (地支). Six pairs of branches that secretly combine, creating hidden alliances and mutual attraction. The six pairs are Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, Si-Shen, Wu-Wei.

Understanding Six Harmonies (Liu He)

Six pairs of branches that secretly combine, creating hidden alliances and mutual attraction. The six pairs are Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, Si-Shen, Wu-Wei. This interaction is one of the core mechanisms through which the twelve Earthly Branches (each corresponding to a zodiac animal) influence each other dynamically. Unlike static elemental classifications, branch relations describe active relationships — energies that transform, combine, conflict, or harmonize when they meet in a chart.

Rat-Ox, Tiger-Pig, Rabbit-Dog, Dragon-Rooster, Snake-Monkey, Horse-Goat form the six harmonic pairs.

How Six Harmonies (Liu He) Works in a BaZi Chart

When the branches involved in Six Harmonies (Liu He) appear together in a person’s four pillars — or when they are triggered by annual luck cycles (Da Yun) or yearly branches — the Six Harmonies (Liu He) interaction activates. Its effects depend on which pillars are involved: Year-to-Day interactions affect social relationships and public life, while Month-to-Day interactions have a more personal, intimate impact.

The strength of the Six Harmonies (Liu He) interaction also depends on whether the involved branches are your Day Branch (spouse palace), Month Branch (career/parents), or Year Branch (ancestry/society). Each position modifies how the interaction manifests in real life.

Six Harmonies (Liu He) in Compatibility Analysis

The Six Harmonies (Liu He) interaction is crucial in relationship compatibility analysis. When two people’s charts share branches that form Six Harmonies (Liu He), the relationship takes on the characteristics of this interaction. Some Six Harmonies (Liu He) combinations create natural harmony and mutual support, while others create productive tension that challenges both partners to grow.

Six Harmonies (Liu He) in Timing and Luck Cycles

Beyond personality and compatibility, Six Harmonies (Liu He) interactions are also activated by time. When an annual branch or a Da Yun period branch triggers Six Harmonies (Liu He) in your chart, it signals a period when that interaction’s themes will be prominent in your life. Understanding these timing triggers helps you prepare for and navigate life transitions more effectively.

The Deeper Metaphysics

The Six Harmonies (Liu He) interaction reflects ancient Chinese cosmological principles that predate formalized astrology. These branch relations encode observations about natural cycles — seasonal, directional, and energetic — that the ancients mapped onto the twelve animals. The system’s enduring relevance speaks to its accuracy in describing human dynamics through the lens of natural law.
