Mao-You Clash (卯酉冲): The East-West Cardinal Clash of Wood and Metal

When the Gate of Dawn Meets the Gate of Dusk

A Ba Zi chart that holds both 卯 (Mao, yin Wood) and 酉 (You, yin Metal) announces a tension that splits the earthly branches along an east–west axis. This is the 卯酉冲 (Mao-You Clash), one of the six clashes (六冲) that practitioners regard as a dynamic of forceful opposition. Where 卯 opens the door of spring and the peach blossom of love, 酉 seals the harvest and the judgment of harvest. When they collide, the chart signals a life theme of beginning versus ending, attraction versus separation.

Classical Definition

The 《三命通会》 (San Ming Tong Hui) describes the six clashes as “conflicts of direction and intention,” and 卯酉 is specifically named the clash of the Eastern and Western gates. The text states: “卯东酉西，阴阳相战，中正之位受冲，人事多有分离变动。” (Mao east, You west, yin and yin war against each other; when the cardinal positions are struck, human affairs are marked by separation and change.) The 《渊海子平》 (Yuan Hai Zi Ping) adds that 卯 is the position of the morning sun and true peach blossom, while 酉 is the position of the setting moon and a more carnal peach blossom—their conflict stirs both romantic fortune and abrupt endings.

五行 Mechanism: Wood vs Metal

Elementally, this clash is pure destruction: yin Metal (酉) chops yin Wood (卯). The yin–yin dynamic makes the clash internal and subtle rather than overtly aggressive, but the elemental superiority of Metal over Wood means the Wood suffers unless it is heavily supported by water or additional wood. In a chart, 卯酉 does not merely indicate external fights; it produces a splitting of energy—the person may directionally be pulled between home and travel, or between family and career. Because both branches are also the Peach Blossom Stars (桃花), their clash often brings romantic entanglements that are intense but short-lived.

Natally: When Mao and You Are Both in the Birth Chart

A natal 卯酉 clash appears in any pillar pair: year–month, year–day, month–day, month–hour, day–hour, or year–hour. The strength and sphere of the clash depend on their location:

- Month–Hour Clash: Most common. The month represents career or parents, the hour represents children or later years. This configuration often produces a person who changes career paths abruptly or has a fractured relationship with children or subordinates. The peach blossom element can also point to scandals. - Day–Month Clash: The day branch is the spouse palace, the month is the social world. This hints at marriages that begin passionately but dissolve through external involvement, or a person who shifts residences frequently. - Year–Hour Clash: The year is ancestry and early life, the hour is final outcomes. This suggests a family history of migration or separation, and the person may travel far from the birthplace.

Overall, a natal 卯酉 gives the chart owner a restless spirit. They are often impulsive in love, drawn to new experiences, and may have a pattern of “saying goodbye” quickly—whether to people, jobs, or locations.

In 大运 (Luck Pillar): The Clash Activated

When a ten-year luck pillar (大运) arrives that is either 卯 or 酉, and it clashes with the corresponding branch in the natal chart, the period is marked by sharp change. The peach blossom is “opened,” so social and romantic activity spikes dramatically. For a single person, this can mean meeting a partner quickly; for someone already attached, it can mean temptation or breakup. The clash also stirs the element of the involved branches: if the day master is Wood, the luck pillar of 酉 may feel like a decade of being “cut down”—health issues related to the liver or eyes, and financial losses. If the day master is Metal, the luck pillar of 卯 may activate creativity but also bring lawsuits or relationship disputes.

In 流年 (Annual Pillar): Year-Level Events

A year of 卯 or 酉 that clashes with the natal chart triggers events within that calendar year. The intensity depends on whether the clash is also present in the current luck pillar or not. Typical manifestations:

- Sudden romantic encounters or breakups. - Travel to locations directly west or east of the person’s residence. - Legal disputes or arguments with superiors (if the pillar clash involves the month or year). - Injuries to limbs if the clash is strong and the day master is weak.

Because 卯酉 is also the “six clash of moving,” the year often brings a relocation, even if temporary.

Favorable vs Unfavorable Activation

Whether 卯酉 is good or bad depends on the day master’s needs:

- Favorable: If the day master is a weak Metal (庚 or 辛) and the clash destroys excess Wood that is strangling the Metal, the clash can “clear the blockage” and bring sudden promotion or clarity. Similarly, if the day master is a strong Wood and needs to be “pruned,” a 酉 luck pillar can remove dead wood and allow new growth—but this is rare because direct clash is harsh. - Unfavorable: Most of the time, the clash is unfavorable for Wood day masters (甲 or 乙) because their root is being cut. It is also unfavorable for Fire day masters because Wood is their resource; if resource is destroyed, learning and support dry up. For Water day masters, the clash may be neutral or mildly favorable because the clash stirs water’s emotional side.

Always check the overall Ba Zi chart — a single clash can be tempered by six unions (六合) or three trinities (三合). For example, if 卯 is united with 戌 (dog), the clash with 酉 is weakened.

Amplifying Configurations

Certain chart patterns make the 卯酉 clash stronger:

1. Both Branches in the Same Pillar Group: For instance, month 卯 and hour 酉, both heavily rooted in the same season. If the chart has additional Wood or Metal in those pillars, the clash becomes a life theme.

2. Peach Blossom Double Activation: When the 卯 or 酉 also appears in the day branch (spouse palace) and the luck pillar is the opposite branch, the clash triggers a major relationship crisis. This is often seen in charts where the day master is weak and the clash attacks the spouse.

3. Empty Clash (空亡): If either 卯 or 酉 falls in a pillar that is in empty death (空亡), the clash becomes volatile—sudden events that appear and disappear, like a whirlwind romance that ends overnight.

One Final Thought

A Ba Zi chart is a map of potential, not a prison sentence. The 卯酉 clash is a powerful signal of movement, choice, and transformation. Use it as a lens to understand the currents of your life, not as a prophecy of doom.

For a deeper look at your personal chart, explore your Ba Zi chart and see how the earthly branches interact. You may also find it useful to study the stabilizing effect of six unions or the amplifying effect of three trinities to see how this clash can be balanced.
