How to find the Fire in the Furnace
The Na Yin pair up the sixty stem-branch pillars into thirty names; 丙寅 and 丁卯 share Fire in the Furnace. The Na Yin of the year pillar is often called one's life Na Yin, so people with a 丙寅 or 丁卯 year pillar are said to have a Fire in the Furnace life. BaZi years change at Lichun (around 4 February), so anyone born in January or early February uses the previous year's pillar.
| Pillar | Years (1900–2099) |
|---|---|
| 丙寅 | 1926, 1986, 2046 |
| 丁卯 | 1927, 1987, 2047 |
The image and meaning of Fire in the Furnace
Fire in the Furnace is fire held inside a furnace: contained, yet giving off steady heat that can smelt and warm. Traditionally it describes warm, driven people who put their energy to practical use.
A furnace fire needs wood to feed it and a furnace to hold it, so old texts say it welcomes Wood and values its setting. Given the right platform, this enthusiasm gets things done.
How to read it in a chart
- Year pillar
- the year pillar's Na Yin is the “life” Na Yin, traditionally used for a person's general temperament and, in compatibility matching, for comparing two people's Na Yin.
- Day pillar
- the day pillar's Na Yin is seen as closer to the self; some schools use it to add detail on temperament.
- Other pillars
- the Na Yin of the month and hour pillars, luck pillars and years are usually read only as background, not as good or bad on their own.
Fire in the Furnace and the regular Five Phases
- Na Yin element
- Fire in the Furnace's Na Yin element is Fire, taken from the 丙寅–丁卯 pair as a whole.
- 丙寅 (Bing Yin)
- the stem 丙 is Fire, the branch 寅 is Wood.
- 丁卯 (Ding Mao)
- the stem 丁 is Fire, the branch 卯 is Wood.
Common misconceptions
- Na Yin cannot decide good or bad fortune on its own. BaZi analysis rests on the regular Five Phases and the Ten Gods; Na Yin is a supporting symbol.
- A Fire in the Furnace life refers to the year pillar's Na Yin only; it does not make the whole chart Fire.
- Clashing Na Yin in compatibility matching does not mean a poor match; modern readings weigh how the two whole charts fit together.
Frequently asked questions
Do I have a Fire in the Furnace life?
Look at your year pillar: if it is 丙寅 or 丁卯, yes. You can use the years in the table, but if your birthday is before Lichun (around 4 February), use the previous year. The surest way is to check the year pillar's Na Yin in the free calculator.
Is Fire in the Furnace's element just Fire?
Its Na Yin element is Fire, which is not the same as the regular Five Phases used in BaZi. Judging the Day Master's strength and useful god uses the regular elements of the stems and branches, not the Na Yin.
How important is Na Yin in BaZi?
Na Yin is an older supporting system, used for the “life” element of the year and in traditional compatibility matching. Modern BaZi analysis rests on the regular Five Phases, the Ten Gods and the chart's structure, so Na Yin is best read as a symbolic reference.
