If He unions are the "weddings" of a chart, then Chong (沖) is the "wars." Six pairs of Earthly Branches, positioned opposite each other across 180°, form the most powerful conflicts in BaZi. They work like earthquakes: what was stable collapses; what was hidden surfaces. Chong is destiny's "reset", without which real renewal is impossible.
The classic Di Tian Sui 滴天髓 says: 「逢沖則動」 — "Where there is a clash, there is movement." This is the key to understanding Chong. Without Chong, life stagnates. With Chong, it moves — sometimes painfully, sometimes triumphantly. Many outstanding people's biographies are threaded with Chong, activating at their "turning points": leaving their home country, a divorce, founding a company, a shattered career.
1 What Chong is — definition and history
Chong is a clash between two Earthly Branches positioned opposite each other in the circle of 12 branches. The word 沖 in ancient Chinese meant "a rushing current, breaking through barriers." In the context of BaZi, it's "a head-on clash of energies," where two opposing elements meet and mutually destroy (or transform) one another.
The origin of Chong is tied to astronomical observation: branches positioned opposite each other represent opposite points of the solar cycle (for example, the summer and winter solstices, the spring and autumn equinoxes). These points are equal in strength, but opposite in nature — and that's what creates the clash.
The treatise Sān Mìng Tōng Huì 三命通會 ("The Combined Canon of Three Fates") states: 「沖者，兩相對也，必有破」 — "Chong is when two stand opposite each other, and something inevitably breaks." That's the essence: Chong always breaks something. The only question is what, and how valuable it was.
2 The full list — the six clashes
All six Chong pairs, with the details of their elements and the nature of the conflict:
| Pair | Characters | Animals | Elements | Type of clash |
|---|---|---|---|---|
| Zi ↔ Wu | 子 ↔ 午 | Rat ↔ Horse | Water ↔ Fire | Polar (North-South) |
| Chou ↔ Wei | 丑 ↔ 未 | Ox ↔ Goat | Earth ↔ Earth | An earthquake (storehouses) |
| Yin ↔ Shen | 寅 ↔ 申 | Tiger ↔ Monkey | Wood ↔ Metal | Controlling (metal cuts wood) |
| Mao ↔ You | 卯 ↔ 酉 | Rabbit ↔ Rooster | Wood ↔ Metal | Polar (East-West) |
| Chen ↔ Xu | 辰 ↔ 戌 | Dragon ↔ Dog | Earth ↔ Earth | An earthquake (storehouses) |
| Si ↔ Hai | 巳 ↔ 亥 | Snake ↔ Pig | Fire ↔ Water | Controlling (water douses fire) |
Notice: Chou-Wei and Chen-Xu are clashes between two Earths. This is a special type: "storehouses" collide and "break open," releasing the elements hidden inside them. This often means "what was hidden surfaces": secrets, inheritances, hidden talents, old wounds.
3 The mechanics of interaction — how the elements change
Chong isn't "mutual, equal destruction." Someone always wins, and someone loses. Understanding this is the key to applying it in practice.
The rule of the winning element
In a Chong, the branch that controls the other, within the five-elements cycle, wins. For example:
- Zi-Wu: Water douses Fire → Zi (Water) wins, Wu (Fire) suffers.
- Yin-Shen: Metal cuts Wood → Shen (Metal) wins, Yin (Wood) suffers.
- Mao-You: same principle — You wins.
- Si-Hai: Water douses Fire → Hai wins, Si suffers.
- Chou-Wei, Chen-Xu: both Earth. Here, whichever is stronger by season wins — whichever is closer to a supporting element.
What "winning" and "losing" mean
The "winning" branch keeps its energy, but it also spends strength doing so. The "losing" one is heavily weakened, or almost disappears. The hidden stems inside the losing branch suffer: these "guests" flee.
Strengthening and softening Chong
Chong can be softened or strengthened by other combinations:
- Liu He softens Chong. If a "peaceful pair" is holding one of the conflicting branches.
- San He can "pull away" from Chong, or, conversely, provoke it (if the central branch is the one clashing).
- Seasonal support strengthens it. If the conflict happens in "its own" season, the clash is more powerful.
- A triple Chong (if the chart has two identical branches, and the opposite one arrives) is a "multiple clash," a very heavy pattern.
4 Chong in the birth chart — what it means
A Chong in the natal chart is a "built-in conflict." It will show up throughout life, in one form or another. Exactly where depends on its position.
Chong by position
- Year — Month. Conflict with parents, a break from the family line. Often emigration, moving away from your hometown, breaking with the family name. A search for identity.
- Year — Day. The marriage conflicts with the family line. The family doesn't accept the spouse. Or the person chooses a partner "against their parents' wishes."
- Year — Hour. The children "don't resemble" the grandparents/ancestors. A generational rift. Older children often move far away from the grandparents.
- Month — Day. The most painful position. Career and marriage don't coexist. Divorce because of work, or work destroys the relationship. A conflict between calling and personal life.
- Month — Hour. Career and children "pull in different directions." People are often forced to choose.
- Day — Hour. Conflict with the spouse or children. Or conflict between the spouse and the children (a stepmother, a divorce).
A special case: a Chong on the Day Branch
The Day branch is the "Spouse Palace." A Chong touching the Day branch is the primary indicator of a difficult marriage. Especially if it arrives in a Luck Pillar or a Liu Nian year. Divorce, affairs, remarriage — a common story. More detail in our article, "Marriage in BaZi."
5 Chong in the Luck Pillars — activation in a decade
If a Luck Pillar brings a branch that clashes with one of the branches in your chart, that's a decade of upheaval. What exactly gets upended depends on which branch of the chart is involved.
Typical activation scenarios
- A Chong with the Year Branch in a Luck Pillar — emigration, losing touch with your parents, the death of a grandparent, a break from the family line.
- A Chong with the Month Branch — a career change, being let go, starting a business, moving for work.
- A Chong with the Day Branch — divorce, a new marriage, a spouse's serious illness, moving.
- A Chong with the Hour Branch — a crisis with the children, a break from your descendants, an issue with offspring, changes in the younger generation.
Good Chong in the Luck Pillars
Not every Chong is a catastrophe. If a clash "expels" an unfavorable branch from the chart, it's a blessing. For example, if the chart has a "killer" of the Day Master, and a Chong arrives against that branch, it gets "banished." The decade can turn out to be the best of a lifetime: freedom from a long-standing burden.
6 Chong in Liu Nian — annual activation
Every year has a branch that may form a Chong with one of the branches in the chart. That year becomes "the year of the event."
Typical events of an annual Chong
- A job change, being let go, a new contract.
- A move, renovation, selling property.
- Divorce, a breakup, a new marriage.
- Long trips, emigration.
- Injuries, surgeries, accidents (especially if the Chong touches the Day Branch).
- Financial swings — large gains or losses.
- Conflicts with loved ones, lawsuits.
An example of an annual activation
A woman has the branch Zi in her Day pillar. In 2026 (丙午, Bing-Wu), the Wu-Horse arrives. Zi-Wu = Chong. This is her "year of marital upheaval." Possible scenarios: divorce, moving with the spouse, a serious family crisis, or, conversely, a rethinking and renewal of the relationship (if she "works" with the Chong consciously).
7 Positive effects — when Chong works for you
Surprisingly, Chong can be a welcome guest. This happens in a few cases:
Among the military, athletes, politicians, and entrepreneurs, a Chong in the Luck Pillars is often a sign of a breakthrough. They "take the energy of the clash" and direct it at their goals. Many generals, champions, and business founders were born with active Chong in their charts.
8 Negative effects — when Chong breaks the balance
1. A blow to a favorable branch
If a Chong destroys a branch that was your "helper" (Yong Shen), that's a loss of strength. For example, your "wealth" is Wood, and in the chart, Yin (Tiger) is its main source. A Chong arrives with Shen (Monkey) — the Wood is cut, the money leaves.
2. A blow to the Day Branch (the Spouse Palace)
The most sensitive of all Chong. The marriage comes under siege. Divorce, serious quarrels, a spouse's illness — typical scenarios. Especially if a Chong in the Luck Pillars overlaps with a Chong in Liu Nian — the year can be critical.
3. Health at risk
Chong is a "blow" to the organs tied to the element. For example, the Zi-Wu Chong hits the heart (Fire) and kidneys (Water) at once. The Mao-You Chong hits the liver (Wood) and lungs (Metal). Chong activating in years with already weakened health are especially dangerous.
4. Emotional instability
A Chong on the Day or Month branch often brings emotional swings: depression, anxiety, rage. The person feels "the ground disappearing underfoot." This is normal, but it calls for psychological support.
5. Financial turbulence
A Chong on the branch that holds your wealth element means sharp money swings. Large inflows, large expenses, unexpected bills. No stability.
9 Combinations with other links
Chong + Liu He (合解沖)
If the branch caught in a Chong also enters a Liu He union with another, the union "holds" it, softening the clash. In the classics, this is called "He dissolves Chong." For example, there's a Zi-Wu Chong, but the chart also has a Chou — Chou forms a Liu He with Zi, holding Zi back from a full clash. The divorce doesn't happen, but there's still a crisis in the marriage.
Chong + San He
If the Chong touches the central branch of a Triple Union (Mao, Wu, You, Zi), the union is destroyed. If it touches an outer branch, the union is weakened. This is especially dramatic when a San He had already activated, and then a Chong arrives: "everything that was built collapses."
Chong + Xing (punishment)
When a Chong combines with a Xing punishment, it's a "forced separation." Not just a break, but one with conflict, litigation, scandal. A divorce through the courts, being fired amid scandal, a criminal case. A heavy pattern.
Double and triple Chong
If the chart already has two identical branches, and the opposite one arrives, that's "a blow to both at once." For example, the chart has two Zi (in the Year and Day), and Wu arrives in a Luck Pillar — two Chong at once. A very heavy activation. This configuration is sometimes called "a divided destiny."
10 Practical examples from charts
Example 1. A divorce through a Day Chong
A woman born in 1980, Day pillar Yi-Hai (乙亥). In the 2018-2028 Luck Pillar, Si arrived — a Si-Hai Chong. In parallel, in 2023 (癸卯), Mao arrived, forming a Chong with You (the Rooster in her Hour). The double activation hit her marriage and career at the same time. She divorced, left her job, moved to another city. Two years later — a new life.
Example 2. A liberating Chong
A man with a Bing (Fire) Day Master, naturally strong. His chart has a Zi (Water) — a powerful "killer" of Fire, which had caused health problems since childhood. In the 2010-2020 Luck Pillar, Wu arrived — a Zi-Wu Chong. Zi was "banished," and the illnesses passed. The decade became his best: he built a company, got married, restored his health.
Example 3. A storehouse Chong — an inheritance
A woman with Chen (辰) in her chart. In 2024, Xu (戌) arrived — a Chen-Xu Chong. "The Earth storehouse opened." That year, she received an unexpected inheritance from a distant relative, and, in parallel, long-forgotten skills "opened up" — she began painting and selling artwork. An Earth Chong is often a "surface flood": what was hidden comes out.

A man with Shen in his Month pillar. The year 戊寅 (Yin) arrived. A Shen-Yin Chong. His career was at risk. He resigned, started his own business. A year after a confident launch, he realized: the Chong had banished the "toxic branch of corporate work" from his chart — he was made for entrepreneurship. The Chong "broke what needed breaking anyway."
Example 5. Strategic work with a Chong
A married couple. The husband's 2025-2035 Luck Pillar carries a Chong on the Day Branch — a high risk of divorce. Learning this two years in advance, they went to therapy together, changed their environment (moving from a megacity to a quiet suburb), and strengthened their communication. The Chong "passed through" a trip and a move, rather than through a divorce. Knowing the chart made it possible to choose the form of the activation.
Conclusion
Chong clashes are, at once, the most frightening and the most valuable mechanism in BaZi. Without them, life would be flat and stagnant. With them, it becomes "life with a capital L": change, ruptures, renewal, breakthroughs. Understanding your own Chong isn't a way to "avoid" them (that's impossible) — it's a way to live through them consciously.
A good BaZi master isn't someone who promises to "remove your Chong" (no one can). It's someone who helps you understand exactly what a Chong will bring and how to extract growth from it. Chong is the fire of destiny. It will burn away everything unnecessary. What remains is you.
