What is Great Stream Water (大溪水)?
The Na Yin of 甲寅 and 乙卯
Short answer
Great Stream Water (Da Xi Shui, 大溪水) is one of the thirty Na Yin of the sixty-pillar cycle. Its image is a big, rushing stream; it belongs to the 甲寅 (Jia Yin) and 乙卯 (Yi Mao) pillars, and its Na Yin element is Water. People with either as their year pillar are often said to have a Great Stream Water life.

How to find the Great Stream Water
The Na Yin pair up the sixty stem-branch pillars into thirty names; 甲寅 and 乙卯 share Great Stream Water. The Na Yin of the year pillar is often called one's life Na Yin, so people with a 甲寅 or 乙卯 year pillar are said to have a Great Stream Water 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) |
|---|---|
| 甲寅 | 1914, 1974, 2034, 2094 |
| 乙卯 | 1915, 1975, 2035, 2095 |
The image and meaning of Great Stream Water
Great Stream Water is a big mountain stream: full, fast and cutting through rock. Traditionally it describes energetic, action-driven people who break through obstacles.
A stream gathers tributaries as it flows, so this Na Yin is often read as good at pulling resources together and widening as it goes, while keeping its direction and avoiding rash moves.
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.
Great Stream Water and the regular Five Phases
- Na Yin element
- Great Stream Water's Na Yin element is Water, taken from the 甲寅–乙卯 pair as a whole.
- 甲寅 (Jia Yin)
- the stem 甲 is Wood, the branch 寅 is Wood.
- 乙卯 (Yi Mao)
- the stem 乙 is Wood, 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 Great Stream Water life refers to the year pillar's Na Yin only; it does not make the whole chart Water.
- 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 Great Stream Water life?
Look at your year pillar: if it is 甲寅 or 乙卯, 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 Great Stream Water's element just Water?
Its Na Yin element is Water, 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.
