Nayin compatibility: Metal lives, Water lives and the pillar being compared
Nayin (a separate named element classification for a complete pair of chart symbols) groups the sixty stem–branch combinations in pairs under thirty names: Jia-Zi and Yi-Chou, for example, share Ocean Metal. Nayin compatibility compares these labels after selecting the pillars involved, such as Year or Day Pillars. It is different from comparing Day Masters. Someone called an Ocean Metal life need not have a Metal Day Master (the birth-day element used as the chart’s reference); first ask which pillar supplied the label.
How do Nayin names attach to stem–branch pairs?
These four groups supply the examples used here. Two different pillars share each Nayin name. The phase belongs to the complete stem–branch classification, not just to the visible stem or a sum of hidden stems (the additional element symbols traditionally assigned inside each lower chart symbol).
| Pillars | Nayin name | Nayin phase |
|---|---|---|
| Jia-Zi, Yi-Chou | Ocean Metal | Metal |
| Bing-Yin, Ding-Mao | Furnace Fire | Fire |
| Wu-Chen, Ji-Si | Great Forest Wood | Wood |
| Bing-Zi, Ding-Chou | Ravine Water | Water |
Why can Jia-Zi and Bing-Zi suggest both Metal→Water and Wood→Fire?
Treat Jia-Zi and Bing-Zi as Day-Pillar (the two-symbol column for the birth day) fragments. Their Nayin labels are Ocean Metal and Ravine Water, giving Metal generating Water at that level. Their Day Stems are Jia Wood and Bing Fire, giving Wood generating Fire. The statements use different classifications; neither rewrites the other.
Both Day Branches are Zi: that is an identical branch, not a Six Combination. Generating Nayin phases do not establish shared useful functions or personalities. Separate Nayin, Day Stem (the upper symbol in the birth-day column) and Day Branch (the lower symbol in the birth-day column) into distinct columns and the apparent contradiction becomes understandable.
Why keep Year-Pillar and Day-Pillar methods separate?
Everyday “life element” language often omits the reference. Some methods compare Year-Pillar (the two-symbol column for the birth year) Nayin, some Day Pillars, and others examine several pillars. State the exact pillars and symbols for both people. Quietly using a Year Pillar for one and a Day Pillar for the other changes the method.
Check chart calculation near the adopted year or day boundary. A different pillar changes the lookup input; it should not be selected just to improve a match. An unknown hour leaves the Hour-Pillar (the two-symbol column for the birth hour) Nayin unknown rather than inviting a guess.
How should Ocean Metal and Furnace Fire imagery be read?
The names use natural imagery to distinguish different stem–branch combinations within the same phase. Sanming Tonghui’s Nayin discussion goes beyond a phase-generation table into imagery such as the sea, a furnace and forest, with additional conditions. This documents a traditional interpretive approach.
Reducing every Fire-life/Metal-life pair to “Fire controls Metal, so they should not be together” even omits those traditional distinctions. Adding poetic detail still does not validate a relationship judgment. The names explain historical classifications, not approved or forbidden partners or wealth after marriage.
