Branch Clashes in a BaZi Chart

A clash (冲) is the most visible interaction between Earthly Branches in BaZi. The term describes two branches that sit opposite each other on the circle of twelve and therefore pull the chart in opposite directions. In a Bazi.uz reading the six clashes are the only branch interaction used for interpretation: if two branches of the chart form such a pair, the reading says so and ties the description to the specific pillars.

Why opposite branches clash

The twelve Earthly Branches are the twelve months of the solar year and the twelve two-hour periods of the day (see The 12 Earthly Branches). Arrange them in a circle and each branch faces the one six steps away. That is half a year and half a day apart: midwinter against midsummer, midnight against noon.

Opposite branches usually carry opposite elements as well: Water against Fire, Metal against Wood. Metal controls Wood and Water puts out Fire, so the tradition describes such a pair not as quiet neighbours but as a jolt, a movement, a restructuring. Two pairs are made of Earth branches (丑–未 and 辰–戌): here the element is the same, and what clashes is the content and the season. The tradition calls this "opening the storehouses", because each of these branches keeps the remnant of the season just ended in its Hidden Stems.

The six clashes: a table

The animals in the table are only labels for the branches. Interpretation rests on the elements, the Hidden Stems and the position in the chart, not on an image of "Tiger versus Monkey".

In the tradition, the strength of a clash depends on several things. Water–Fire and Metal–Wood pairs are considered sharper; Earth pairs more "internal". Adjacent pillars (hour and day, day and month, month and year) clash more noticeably than distant ones (hour and year). Finally, the Hidden Stems matter: if the affected branch holds the Day Master's root (its own element as main qi), the clash touches the very support of the chart.

What a clash means depending on the pillars

Each pillar is a palace, an area of life (see Palaces of the Chart). A clash is read as tension or mobility between the two areas the pair connects.

These are tendencies, not events. A clash does not mean "bad": in the tradition it also describes mobility, readiness for change and the ability to break out of stagnation. Much depends on which of the Ten Gods are involved: if, for example, Seven Killings or the Wealth element is hit, the theme of the clash shifts towards demands or resources. The table of relationships is in The Ten Gods.

Combinations also matter. In the tradition, if one branch of a clash also combines with a third branch, the tension is partly "untied". Schools weigh this differently; see Branch Combinations.

Example: 寅–申 in a chart with a 甲 Day Master

In the reference example the pillars are 丙寅 (hour), 甲申 (day), 辛巳 (month) and 庚午 (year). The hour branch 寅 and the day branch 申 form a Wood–Metal clash.

• The main qi of 寅 is 甲 (Jia), the same element as the Day Master. This is its root, and for a Jia Day Master in a leaning-weak chart the root matters especially.
• The main qi of 申 is 庚 (Geng), which is Seven Killings for 甲. Metal controls Wood, so the tradition reads this clash as pressure on the Day Master's support.
• By palace: 申 is the spouse palace and 寅 the palace of children and long projects. The description is about the personal sphere and one's own ventures tending to compete for attention, not about specific events.

At the same time 申 combines with 巳 in the month pillar. The tradition would say the clash is softened by the combination; a Bazi.uz reading shows the combination for reference and draws no conclusions from it. In methodology v1 the Day Master strength assessment does not take clashes into account: it is built on the season, the balance of support and drain, and roots.

Clashes with the annual pillar and the Luck Pillar

Branches of the chart do not only meet each other. Every year brings its own annual pillar, and every ten years the Luck Pillar changes. If the branch of the year or of the Luck Pillar stands opposite a branch of the chart, the tradition says the corresponding palace "is set in motion".

• Year against the day branch — a period usually described as a time of rearrangement in personal space: changes of routine, of home, of arrangements.
• Year against the month branch — a tendency towards change at work and in one's environment.
• Luck Pillar against a chart branch — a background for the whole decade: the palace's theme stays mobile longer than in a single year.

In the example, the Luck Pillar 甲申 (ages 26–36) and the year 戊申 (2028) carry 申 and touch 寅 in the hour pillar again. The tradition would read such a year as a period when the theme of long projects and personal support becomes especially visible — a tendency worth taking into account, not a promise.

To be clear about what a Bazi.uz reading does today: it takes clashes within the chart into account. Clashes between the chart and the current Luck Pillar or the Annual Pillars are a developing part of the methodology; those pillars are shown on the chart page, and you can match their branches against the table above yourself.

How to find clashes in your chart

1. Write down the four branches — hour, day, month and year (three without a birth time).
2. Check each pair against the table of six clashes.
3. Note which palaces are linked and what sits in the Hidden Stems of the affected branches — see Hidden Stems.
4. Add the branches of the current Luck Pillar and the coming years.
