Zi-Chou Harmony into Earth (子丑合土)
Learn how Zi and Chou form one Six-Harmony pair, what supports the conventional Earth tendency, and why Water, cold, roots, and clashes remain relevant.
Overview
Zi–Chou Harmony (子丑合土) joins the Zi Water and Chou Earth branches. The pair is detected before any phase conversion is considered. Proximity, Month Command, cold and moisture, Chou’s hidden stems, roots, competing branch structures, and Wu–Zi or Chou–Wei clashes determine whether it binds, supports Earth, or remains only a harmony relation.
At a glance
- Pair
- Zi and Chou
- Conventional tendency
- Earth, subject to a declared school rule
- Key context
- Cold, moisture, Chou hidden stems, and Month Command

- The pair does not automatically transform or predict partnership
- Original evidence
- Zi Water, Chou Earth, and every hidden stem remain visible
- Reported status
- Harmony only, Earth tendency, damaged pair, or supported transformation
Confirm branch contact before Earth attribution
Locate Zi and Chou and record their pillars and chart layers.
The fixed pair creates a harmony relation; it does not erase Zi Water or Chou’s mixed hidden stems.
- Verify both branches.
- Preserve source identities.
Test Earth against cold and moisture
Month Command, Earth roots, exposed Earth, and chart temperature determine whether the Earth tendency is usable.
Strong Water, severe cold, or absent Earth support can keep the relation at combination-only status.
- Assess climate and roots.
- Do not assume conversion.
Resolve clashes and competing assemblies
Zi may clash Wu, while Chou may clash Wei or enter a Metal trine and northern meeting.
Publish every overlap and compare support rather than declaring one relation automatically cancels all others.
- Map every branch relation.
- Explain priority evidence.
Keep harmony technical
子丑合土 does not prove marriage, loyalty, property, fertility, or a favorable Earth event.
Timing activation is temporary and must be compared with the natal baseline.
- No social guarantee.
- Date timing effects.
