What Is Pine and Cypress Wood (松柏木) in BaZi?
Identify the 庚寅–辛卯 Pine and Cypress Wood pair, its mountain, water, season, and fire conditions, and the limits of its endurance imagery.
Overview
Pine and Cypress Wood is the wood-class Nayin assigned to 庚寅 and 辛卯. San Ming Tong Hui describes vigorous eastern wood that prefers a mountain foundation and water nourishment, then distinguishes exact waters, fires, earths, metals, and seasons; evergreen imagery does not prove resilience, status, health, or longevity.

Pine and Cypress Wood belongs to 庚寅 and 辛卯
The Nayin table gives this name only to complete 庚寅 and 辛卯 pillars. A Geng or Xin stem, a Yin or Mao branch, an evergreen tree, or characters assembled from separate pillars are not enough.
庚 and 辛 remain metal stems; 寅 and 卯 remain wood branches with their normal hidden stems. The wood Nayin adds a historical pair image without erasing the metal stems or manufacturing ordinary wood elsewhere in the chart.
- Verify the complete Jiazi in one pillar.
- Retain the ordinary stem, branch, and hidden-stem structure.
Mountain foundation and water nourishment are specific conditions
San Ming Tong Hui pictures tall evergreen wood enduring frost. It calls for a mountain as foundation and water as nourishment, then differentiates Heavenly River, Stream-Below, Great Stream, and Great Sea water by exact Jiazi and by whether a mountain is present.
Fire is not automatically useful: Furnace Fire and several other named fires can damage the image, while particular earth, metal, wood, and winter conditions are treated separately. Historical status and lifespan judgments are excluded from modern use.
- Identify the exact mountain, water, or seasonal condition.
- Do not flatten named fire and metal rules into generic phase slogans.
Evergreen imagery stays outside the main chart score
OpenFate deterministically maps 庚寅 and 辛卯 to Pine and Cypress Wood. Compatibility treats it as non-scoring auxiliary evidence and keeps direct pillar interactions, structure, and favorable-element findings in control.
Real wood strength and usefulness depend on season, roots, hidden and exposed stems, support, control, combinations, clashes, dryness, moisture, and timing. The evergreen name cannot establish that wood is strong, rooted, useful, or indestructible.
- Keep the Nayin lookup separate from strength analysis.
- Let whole-chart evidence determine actual wood.
An evergreen is not a resilience or longevity test
Pine and Cypress Wood does not prove toughness, moral uprightness, leadership, emotional reserve, winter affinity, superior health, long life, or a construction career. Botanical imagery is not a human assessment.
Medical, employment, relationship, education, and safety decisions require current facts and qualified support. Never use the Nayin to pressure someone to endure hardship or to promise immunity from harm.
- Do not convert endurance imagery into character or health claims.
- Do not use the label to rank resilience or predict lifespan.
