Six Harms (六害)

In BaZi astrology, the Six Harms (Liu Hai) (六害) is one of the fundamental interactions between Earthly Branches (地支). Six pairs of branches that create hidden damage, misunderstanding, and subtle sabotage. Unlike clashes (which are overt), harms work beneath the surface.

Understanding Six Harms (Liu Hai)

Six pairs of branches that create hidden damage, misunderstanding, and subtle sabotage. Unlike clashes (which are overt), harms work beneath the surface. 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-Goat, Ox-Horse, Tiger-Snake, Rabbit-Dragon, Monkey-Pig, Rooster-Dog form the six harmful pairs.

How Six Harms (Liu Hai) Works in a BaZi Chart

When the branches involved in Six Harms (Liu Hai) appear together in a person’s four pillars — or when they are triggered by annual luck cycles (Da Yun) or yearly branches — the Six Harms (Liu Hai) 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 Harms (Liu Hai) 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 Harms (Liu Hai) in Compatibility Analysis

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

Six Harms (Liu Hai) in Timing and Luck Cycles

Beyond personality and compatibility, Six Harms (Liu Hai) interactions are also activated by time. When an annual branch or a Da Yun period branch triggers Six Harms (Liu Hai) 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 Harms (Liu Hai) 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.
