What Is Earth on the Wall (壁上土) in BaZi?
Identify the 庚子–辛丑 Earth on the Wall pair, its beam, ground, water, fire, and metal conditions, and its limits for protection and housing claims.
Overview
Earth on the Wall is the earth-class Nayin assigned to 庚子 and 辛丑. San Ming Tong Hui pictures a wall that depends on beams and supporting ground, protects a dwelling from weather, and responds differently to named woods, earths, waters, fires, and metals; the image does not prove safety, property, defensive character, or ordinary earth strength.

Earth on the Wall belongs to 庚子 and 辛丑
The fixed Nayin table assigns Earth on the Wall only to complete 庚子 and 辛丑 pillars. A Geng or Xin stem, a Zi or Chou branch, an actual wall, or characters collected from separate pillars do not establish it.
庚 and 辛 remain metal stems; 子 remains a water branch and 丑 an earth branch with their ordinary hidden stems. The earth Nayin adds a pair-level image without replacing those components or adding ordinary earth to the chart.
- Match the complete stem-branch pair in one pillar.
- Preserve the original phases and hidden stems.
A wall requires structure, support, and exact materials
San Ming Tong Hui describes wall earth that leans on beams, forms doors, and shelters a dwelling from heat, cold, frost, and snow. It requires a supporting ground, treats 子午 as named central pillars, and distinguishes framing wood from wood damaged by clashes or unsupported by earth.
Roadside Earth bears the wall, while House and City-Wall Earth may protect it. Fire is generally difficult and may need specified water relief; Heavenly River and Well-Spring waters are not interchangeable, Gold Foil decorates only with wood present, and Sword Edge Metal may damage the wall.
- Name the beam, bearing earth, and clash conditions.
- Do not reduce the passage to “earth controls water” or “fire produces earth.”
Shelter imagery remains outside the main score
OpenFate deterministically maps 庚子 and 辛丑 to Earth on the Wall. Compatibility keeps the label auxiliary and non-scoring, so it cannot override direct pillar relations, chart structure, or favorable-element findings.
Actual earth strength and function depend on season, roots, hidden and exposed stems, support, control, combinations, clashes, dryness, moisture, and timing. A wall image does not prove that earth is stable, useful, dry, or protected.
- Keep the fixed Nayin lookup separate from scoring.
- Judge ordinary earth through the complete chart.
A wall is not a personal safety or property profile
Earth on the Wall does not prove defensiveness, emotional barriers, reliability, home ownership, construction skill, physical security, legal protection, immunity from weather, or danger from weapons. Architectural imagery is not a psychological or safety assessment.
Housing, engineering, insurance, employment, relationship, and security decisions require inspections, direct evidence, consent, and qualified advice. Do not promise protection or label someone inaccessible because of this Nayin.
- Exclude personality, property, and security predictions.
- Use professional evidence for buildings and consequential safety decisions.
