What is Wall Earth (壁上土)?
The Na Yin of 庚子 and 辛丑
Short answer
Wall Earth (Bi Shang Tu, 壁上土) is one of the thirty Na Yin of the sixty-pillar cycle. Its image is earth plastered on a wall; it belongs to the 庚子 (Geng Zi) and 辛丑 (Xin Chou) pillars, and its Na Yin element is Earth. People with either as their year pillar are often said to have a Wall Earth life.

How to find the Wall Earth
The Na Yin pair up the sixty stem-branch pillars into thirty names; 庚子 and 辛丑 share Wall Earth. The Na Yin of the year pillar is often called one's life Na Yin, so people with a 庚子 or 辛丑 year pillar are said to have a Wall Earth 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) |
|---|---|
| 庚子 | 1900, 1960, 2020, 2080 |
| 辛丑 | 1901, 1961, 2021, 2081 |
The image and meaning of Wall Earth
Wall Earth is the earth plastered onto a wall: it depends on the wall yet protects the house and keeps out the cold. Traditionally it describes cooperative, reliable people who hold a team together.
Plaster needs beams and posts to do its job, so this Na Yin is often read as doing best with the right platform and partners, achieving things through the strength of a group.
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.
Wall Earth and the regular Five Phases
- Na Yin element
- Wall Earth's Na Yin element is Earth, taken from the 庚子–辛丑 pair as a whole.
- 庚子 (Geng Zi)
- the stem 庚 is Metal, the branch 子 is Water.
- 辛丑 (Xin Chou)
- the stem 辛 is Metal, 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 Wall Earth life refers to the year pillar's Na Yin only; it does not make the whole chart Earth.
- 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 Wall Earth life?
Look at your year pillar: if it is 庚子 or 辛丑, 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 Wall Earth's element just Earth?
Its Na Yin element is Earth, 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.
