What is Metal in the Sea (海中金)?
The Na Yin of 甲子 and 乙丑
Short answer
Metal in the Sea (Hai Zhong Jin, 海中金) is one of the thirty Na Yin of the sixty-pillar cycle. Its image is gold resting on the seabed; it belongs to the 甲子 (Jia Zi) and 乙丑 (Yi Chou) pillars, and its Na Yin element is Metal. People with either as their year pillar are often said to have a Metal in the Sea life.

How to find the Metal in the Sea
The Na Yin pair up the sixty stem-branch pillars into thirty names; 甲子 and 乙丑 share Metal in the Sea. The Na Yin of the year pillar is often called one's life Na Yin, so people with a 甲子 or 乙丑 year pillar are said to have a Metal in the Sea 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) |
|---|---|
| 甲子 | 1924, 1984, 2044 |
| 乙丑 | 1925, 1985, 2045 |
The image and meaning of Metal in the Sea
Metal in the Sea is gold hidden in the deep: valuable but out of sight. Traditionally it describes people with real substance who don't rush to show it, whose talents often take time and the right chance to be seen.
Because the metal lies in water, old texts say it does not fear being smelted, yet needs the right conditions to come to the surface. It is often read as a late bloomer: a long build-up, then a strong showing.
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.
Metal in the Sea and the regular Five Phases
- Na Yin element
- Metal in the Sea's Na Yin element is Metal, taken from the 甲子–乙丑 pair as a whole.
- 甲子 (Jia Zi)
- the stem 甲 is Wood, the branch 子 is Water.
- 乙丑 (Yi Chou)
- the stem 乙 is Wood, the branch 丑 is Earth.
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 Metal in the Sea life refers to the year pillar's Na Yin only; it does not make the whole chart Metal.
- 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 Metal in the Sea life?
Look at your year pillar: if it is 甲子 or 乙丑, 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 Metal in the Sea's element just Metal?
Its Na Yin element is Metal, 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.
