BAZI KNOWLEDGE BASE
What Is Pine and Cypress Wood (松柏木) in BaZi?
Pine and Cypress Wood is the wood-class Nayin (a separate named element classification for a complete pair of chart symbols) 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.
What does Pine and Cypress Wood establish first?
Pine and Cypress Wood is the Nayin name for a complete 庚寅 or 辛卯 pillar, and its Nayin phase is Wood. It may occur in the Year, Month, Day or Hour Pillar (the two-symbol column for the birth hour). The lookup unit is always one stem–branch pair in the same pillar, never a single character or a cross-pillar combination.
This lookup establishes one historical classification. 庚 remains a Metal stem and 寅 a Wood branch; 辛 remains a Metal stem and 卯 a Wood branch. Nayin Wood does not overwrite those ordinary Five-Phase facts.
How can you check for Pine and Cypress Wood?
Read each complete pillar in an already calculated chart. A pillar that is exactly 庚寅 or 辛卯 has the Pine and Cypress Wood Nayin. One matching character, a zodiac animal or a real-world object is insufficient.
| Complete Jiazi | Stem phase | Branch phase | Nayin name | Nayin phase |
|---|---|---|---|---|
| 庚寅 | Metal | Wood | Pine and Cypress Wood | Wood |
| 辛卯 | Metal | Wood | Pine and Cypress Wood | Wood |
Worked example: how should a 庚寅 Year Pillar be recorded?
Suppose the Year Pillar (the two-symbol column for the birth year) is 庚寅. The table returns Pine and Cypress Wood. A clear record says: Year 庚寅; stem 庚 is Metal, branch 寅 is Wood; Nayin is Pine and Cypress Wood, classed as Wood. This keeps the Nayin field separate from ordinary elemental data.
If 辛 appears only in the Month Pillar (the two-symbol column for the birth month) and 卯 only in the Day Pillar (the two-symbol column for the birth day), they do not form the same-pillar 辛卯 combination and do not create Pine and Cypress Wood. Complete pairing comes before image interpretation.
Why does the source use the name Pine and Cypress Wood?
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.
What value does Pine and Cypress Wood offer a modern reader?
Its practical value is precise lookup: 庚寅 and 辛卯 share this Nayin name, which lets you locate the pair’s distinctive source image and conditions. If another pillar enters an older rule, record that full Jiazi, its location and the source before drawing a comparison.
Keep the reading order explicit: verify calendar inputs and the Four Pillars; retain stems, branches and hidden stems; evaluate Month Command and Day-Master structure; only then add Pine and Cypress Wood as a Nayin layer. One Nayin name does not determine strength, Useful God, personality, work, relationships, wealth, health or event timing.
