BAZI KNOWLEDGE BASE
What Is Mulberry Wood (桑柘木) in BaZi?
Mulberry Wood is the wood-class Nayin (a separate named element classification for a complete pair of chart symbols) assigned to 壬子 and 癸丑. San Ming Tong Hui links it to mulberry cultivation, silkworms, silk, bows, and a required soil foundation, then evaluates exact supporting pairs; the image is not evidence of occupation, talent, body, wealth, or ordinary wood strength.
What does Mulberry Wood establish first?
Mulberry Wood is the Nayin name for a complete 壬子 or 癸丑 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. 壬 remains a Water stem and 子 a Water branch; 癸 remains a Water stem and 丑 a Earth branch. Nayin Wood does not overwrite those ordinary Five-Phase facts.
How can you check for Mulberry Wood?
Read each complete pillar in an already calculated chart. A pillar that is exactly 壬子 or 癸丑 has the Mulberry 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 |
|---|---|---|---|---|
| 壬子 | Water | Water | Mulberry Wood | Wood |
| 癸丑 | Water | Earth | Mulberry Wood | Wood |
Worked example: how should a 壬子 Year Pillar be recorded?
Suppose the Year Pillar (the two-symbol column for the birth year) is 壬子. The table returns Mulberry Wood. A clear record says: Year 壬子; stem 壬 is Water, branch 子 is Water; Nayin is Mulberry Wood, classed as Wood. This keeps the Nayin field separate from ordinary elemental data.
If 癸 appears only in the Month Pillar (the two-symbol column for the birth month) and 丑 only in the Day Pillar (the two-symbol column for the birth day), they do not form the same-pillar 癸丑 combination and do not create Mulberry Wood. Complete pairing comes before image interpretation.
Why does the source use the name Mulberry Wood?
San Ming Tong Hui presents mulberry as the basis of silkworm and silk production and also mentions its use for bows. It values Sand Earth as a rooting (elemental support found inside the lower chart symbols) base and associates 辰 and 巳 with the place where silkworms are fed, while warning about clashes that break the intended structure. Water, fire, metal, wood, and earth are not treated as undifferentiated remedies. The passage names particular Nayin pairs and often requires a soil foundation before water can nourish the image. Responsible use preserves those named conditions rather than saying that all water helps all wood. Keep the soil foundation and exact companion pairs visible. Do not turn a production image into a universal elemental cure.
What value does Mulberry Wood offer a modern reader?
Its practical value is precise lookup: 壬子 and 癸丑 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 Mulberry Wood as a Nayin layer. One Nayin name does not determine strength, Useful God, personality, work, relationships, wealth, health or event timing.
