In the Chinese tradition, the Snake is the "little dragon." Its branch 巳 (sì — Snake) is considered one of the most intellectual and unfathomable of all twelve. Around the New Year, entertainment sites write that "the year of the Snake is a year of wisdom and intrigue," but behind this lies a precise technical structure: the Snake is the peak of the spring-to-summer transition, the moment when Fire is just kindling and Metal is being born. Let's examine it honestly, per the canon of the Joey Yap school.
1 What the Year of the Snake 巳 means in BaZi
When someone says "I was born in the year of the Snake," in the language of BaZi this means: their earthly branch of the year pillar is 巳 (sì — Snake). This is the sixth of the twelve branches in the cycle. By its nature, 巳 is Yang Fire 丙 (bǐng — Fire): the powerful, overt, solar flame of early summer.
A curious subtlety of the canon: although in the "zodiac" system the Snake is sometimes marked as a "yin" sign (an odd position), by its true nature of hidden fire 巳 carries Yang Fire 丙. This is precisely why the Snake is called the "little dragon": outwardly reserved, inwardly it blazes.
Why does the Snake occupy the sixth position in the cycle — right before the peak of summer? In the classical tradition, 巳 is the moment when Fire has already "been born" and is gaining strength, yet still keeps itself in check. This is not the reckless flame of the Horse 午, but a calculated, focused heat. Hence the Snake's reputation as the "smartest" sign of the zodiac: its energy is intellect under pressure, passion under the control of reason. People with a strong 巳 in their chart are credited with the ability to act decisively, but only after weighing the situation. The Snake rarely attacks first — it waits, observes, and strikes precisely at the right moment.
2 The Hidden Stems of the Snake 藏干
The main depth of any branch lies in its hidden stems 藏干 (cáng gān — "hidden heavenly stems"). They are precisely what explains why the Snake is so multilayered and why it is called a cunning strategist.
| Hidden Stem | Pinyin and translation | Element | Role |
|---|---|---|---|
| 丙 | bǐng — Fire (Yang) | Fire 火 | The main stem — the essence of the Snake |
| 庚 | gēng — Metal (Yang) | Metal 金 | The birth of autumn Metal |
| 戊 | wù — Earth (Yang) | Earth 土 | Support and transition |
Three forces live inside 巳: 丙 (bǐng — Fire) as the overt flame, 庚 (gēng — Metal) as the nascent blade, and 戊 (wù — Earth) as the supporting soil. This combination is unique: the Snake is simultaneously hot (丙), sharp and calculating (庚), and stable (戊). Hence the image of a wise strategist who basks in the sun yet always keeps the "blade" ready.
Especially interesting is the hidden Metal 庚. In summer Fire, Metal would seemingly "melt" and weaken — yet it is precisely in 巳 that it is born (this is the so-called point of "birth" 長生 (zhǎng shēng — "long life," the start of the metal cycle). This is the paradox of the Snake: within its heat ripens a cold, sharp beginning. For a practitioner this means that a Snake in the chart can unexpectedly "produce" Metal — money, weapons, a decision, the cutting away of the superfluous — when the union 巳酉丑 is activated or the year of the Rooster 酉 arrives. The hidden Earth 戊 here serves as a bridge: it softens the conflict of Fire and Metal, giving the Snake stability where other signs would burn up in contradiction.
3 The Character of the Snake's Year Layer
Let's stress once more: below is only the year layer, a portrait of the 巳 branch as the energy of lineage and the early years of life. It is not a person's complete psychological type (that is given by the Day Master 日主 (rì zhǔ — "master of the day"), the day stem).
The annual energy of the Snake is traditionally described as follows:
- Wisdom and intellect. The hidden Metal 庚 gives sharpness of mind, analytical ability, the capacity to see the essence behind words.
- Intuition and insight. The Fire 丙 "illuminates" the intentions of others; the Snake seems to read people through and through.
- Mystery and reserve. The Snake does not reveal itself at once — it observes, bides its time, accumulates information.
- Strategy and calculation. The combination of Fire and Metal gives a "cool head with a hot heart" — the Snake plans several moves ahead.
- Magnetism and charm. The hidden flame 丙 attracts; the Snake is often considered charismatic and alluringly mysterious.
The Snake is only the year. But who are you by the day?
The main indicator of character is the Day Master, the day stem. Build a full chart of 8 characters per the Joey Yap school canon and discover your true psychological type, not your "year sign."
Full Chart Reading →4 The Element and Season of the Snake
The element of the Snake is Yang Fire 丙 (bǐng — Fire). Seasonally, 巳 opens summer: it is the beginning of May in the solar calendar, the moment 立夏 (lì xià — "beginning of summer"). Fire is gaining strength, but this is not yet the peak of the heat (the peak belongs to the Horse 午). The Snake is the "sunrise" of summer Fire.
| Parameter | Value |
|---|---|
| Branch | 巳 (sì — Snake) |
| Polarity | Yang by nature 陽 (yáng — "bright, active") |
| Element | Fire 火 (huǒ — "fire") |
| Season | Start of summer (≈ May) |
| Hidden growth | The birth of Metal 庚 (gēng — Metal) |
| Time of day | 09:00–11:00 |
Understanding the season is critical: the Snake-in-May strengthens any Fire in the chart and at the same time "gives birth to" Metal (庚 within). So in a chart that lacks Fire, the appearance of the Snake brings warmth and visibility; while where a water conflict is strong, the Snake becomes the point of the clash 巳亥冲 (sì hài chōng — "clash of Snake and Pig").
5 Compatibility of the Snake 三合 and 沖
This is where popular astrology errs most. Real "compatibility" is not "the Snake suits the Ox," but specific interactions of the earthly branches. For 巳 there are three key ones.
The Triple Union 三合 — Metal
The 三合 (sān hé — "triple union") of the Snake: 巳酉丑 (sì yǒu chǒu — "Snake-Rooster-Ox"). This trio transforms into Metal 金. The Snake 巳 gives birth to Metal, the Rooster 酉 (yǒu — Rooster) is its peak, the Ox 丑 (chǒu — Ox) is the storage. Together they form the most powerful metal frame. If the chart contains a Rooster and an Ox, the arrival of the Snake completes the metal union.
The Six Union 六合 — with the Monkey
The 六合 (liù hé — "six unions," paired combination) of the Snake: 巳申合 (sì shēn hé — "union of Snake and Monkey"). The Snake 巳 and the Monkey 申 (shēn — Monkey) form a pair that gravitates toward Water 水. This is a "harmonious bonding" (though an ambiguous one — there is also a punishment within it): people with such branches often feel drawn to each other in friendship, love, and partnership.
The Clash 沖 — with the Pig
The 沖 (chōng — "clash") of the Snake: 巳亥冲 (sì hài chōng — "clash of Snake and Pig"). The Snake 巳 (Fire) and the Pig 亥 (hài — Pig, Water) are a direct confrontation of Fire and Water. This is not a sentence: the clash signals movement, change, relocations, sharp turns. Many strong couples are built on precisely such a dynamic clash of Fire and Water.
6 Years of the Snake's Birth
The year of the Snake recurs every 12 years. There is an important subtlety from the canon: the same "Snake" comes each time with a different heavenly stem, forming five "versions" — the Wood, Fire, Earth, Metal, and Water Snake. Below are the modern years of the Snake by the solar calendar.
| Year | Stem-Branch | Type of Snake | Element of the year |
|---|---|---|---|
| 1977 | 丁巳 (dīng sì) | Fire Snake | Fire 火 |
| 1989 | 己巳 (jǐ sì) | Earth Snake | Earth 土 |
| 2001 | 辛巳 (xīn sì) | Metal Snake | Metal 金 |
| 2013 | 癸巳 (guǐ sì) | Water Snake | Water 水 |
| 2025 | 乙巳 (yǐ sì) | Wood Snake | Wood 木 |
Note: the exact boundary of the year is not January 1, but the start of the solar month 立春 (lì chūn — "beginning of spring"), around February 4. Those born in late January or early February may belong to the previous sign. This is one reason why it is easy to err by date alone without a precise calculation. Thus, 2025 is the year of the Wood Snake 乙巳.
7 Strengths and Weaknesses of the Snake
Relying on the structure of 巳 (丙 Fire + 庚 Metal + 戊 Earth), one can describe the typical accents of the year layer.
Important: whether the "strengths" manifest as a resource or as a problem depends on whether Fire and Metal are useful to your specific chart. For one Day Master the Snake is wealth, for another it is pressure. Without the full chart it is impossible to say.
The Snake's shadow side is born from its own virtues. The ability to see through people easily turns into distrust; strategic patience into manipulation and intrigue; self-control into emotional coldness and closedness. The inner tension of "fire against metal" (passion against calculation) makes the Snake a person of contradictions: it can simultaneously burn with desire and coldly renounce it. In fortunate periods this gives rare discipline and wisdom; in unfortunate ones — jealousy, suspicion, and a tendency to weave elaborate plans where simplicity would suffice. Which side will prevail can be understood only from the full chart — through the Day Master and the luck pillars.
8 Career and Money of the Snake
The Snake's year layer gravitates toward fields where intelligence, strategy, and precision are needed. The Fire 丙 is publicity, presentation, media, the spotlight. The hidden Metal 庚 is finance, law, engineering, weapons, surgery. The Earth 戊 is real estate, brokerage, transitional roles.
- Strategy, analytics, consulting — the Snake sees several moves ahead.
- Finance, law, audit — thanks to the "cold" Metal 庚.
- Medicine, surgery, precise crafts — the Metal-blade plus concentration.
- Public roles, branding, research — the charm of Fire 丙 on stage and in science.
The Snake's financial luck is tied to the activation of the Metal within 巳: the years of the Rooster and the Ox (completing the union 巳酉丑) often strengthen the "money" Metal. But to repeat: the wealth star 財星 (cái xīng — "wealth star") in a chart is determined through the Day Master, not through the year.

In folk tradition, the Snake is "matched" with the Rooster and the Ox (by the triple union 巳酉丑) and the Monkey (by the union 巳申合). And there is a rational kernel to this: the branches really do form a union. But the real compatibility of a couple in BaZi is the analysis of the spouse palace 夫妻宮 (fū qī gōng — "palace of spouses," the day branch) of both people, their Day Masters, and their useful elements.
- Attraction: partners with a Rooster 酉, Ox 丑, or Monkey 申 in their chart often feel "chemistry" with the Snake.
- Tension: a partner with a strong Pig 亥 brings the clash 巳亥冲 — passion mixed with "fire-water" turbulence.
- Depth: the Snake's secrecy makes it a loyal but reserved partner who needs trust and space.
But let's repeat the main point: two "Snakes by year" can be utterly incompatible, while those "incompatible by horoscope" can be a perfect match. The structure of the charts decides, not the year sign.
10 Why You Need the Full Chart
We have examined the Snake honestly: its element, hidden stems 藏干, unions and clashes, years and character. But all of this is only the year layer, one of the eight letters of your name of destiny. To understand a real person, all four pillars are needed.
In the full chart, the Snake takes on meaning: it becomes clear what it is for you — wealth, authority, resource, pressure, or support. Without the Day Master 日主, this question stays unanswered, and a "forecast for the Snake" turns into fortune-telling for one-twelfth of humanity at once.
