BaZi Liu Hai: Does Hidden Harm Lurk in Relationships?

What Are the Six Harms, and Where Do They Come From

Many people first encounter the concept of "mutual harm" while reading compatibility analyses or annual fortune readings. Compared to the Six Combinations and Six Clashes, the word "harm" feels vague and hard to pin down — did something clash or not?

The Six Harms, also called the "Six Piercings" (Liu Chuan), describe a set of relationships between the Earthly Branches, comprising six pairs: Zi-Wei, Chou-Wu, Yin-Si, Mao-Chen, Shen-Hai, and You-Xu. Traditional BaZi (Four Pillars of Destiny) texts are not entirely consistent in how they explain this. One common account holds that when one branch in a harming pair tries to form a Six Combination with a third branch, the other member of the pair happens to "disrupt" that combination — hence the term "harm."

Take Zi and Wei as an example: Zi combines with Chou in the Six Combinations, but Wei has a punishment relationship with Chou. When Wei appears, it interferes with the Zi-Chou combination, and so the tension between Zi and Wei is called a "harm." The logic sounds a bit convoluted, but it is rooted in the positional structure of the Earthly Branches, not invented out of thin air.

Unlike the Six Clashes, which represent direct opposition, the Six Harms work more like lateral interference — not a head-on collision, but a quiet drag from the side. This is why the Six Harms have become associated in popular tradition with "hidden damage."

How Much Does Liu Hai Actually Matter in BaZi (Four Pillars of Destiny)

Honestly, in mainstream traditional BaZi (Four Pillars of Destiny) practice, the Six Harms carry relatively low weight. Most practitioners, when reading a chart, focus first on the strength of the Day Master, the useful gods and their likes and dislikes, and the Luck Pillars and Annual Fortune. The Six Clashes and Six Combinations come next; the Six Harms rank quite a bit further down.

San Ming Tong Hui (Three Fates Comprehensive), a Ming dynasty classic, does mention the Six Harms, but in measured terms — roughly that the harming branches "tend toward some loss" — without developing the kind of systematic interpretive framework that exists for the Six Clashes. Qing dynasty BaZi texts similarly give the Six Harms limited coverage. This suggests that traditional masters never regarded the Six Harms with the dramatic weight that popular culture assigns them.

That said, does the presence of harming branches in a chart have any effect at all? In my view: yes, but position and strength matter greatly.

A harm between the Day Pillar and Hour Pillar is a different matter from one between the Year Pillar and Month Pillar. The Day Pillar governs marriage and the spouse; the Hour Pillar governs children and later years. Harms involving these two positions deserve closer attention. Year and Month Pillar harms point more to family environment and social-level friction, and may not translate directly into specific personal relationships.

Branch strength also matters. If a branch is revealed through a Heavenly Stem, timely, and well-rooted, it carries force. If it falls in an empty void (Kong Wang) or is in a resting, weakened state, its influence is limited. Two harming branches that are both weak will produce very little real effect.

What Happens When Two People's BaZi (Four Pillars of Destiny) Charts Contain a Harm?

The most common question in compatibility readings goes something like: my Day Branch is Zi, my partner's is Wei — we have a harm. Can we be together?

The premise of the question needs adjusting. Compatibility reading does not come down to a single Day Branch. The whole picture matters: whether the Five Elements (Wu Xing) complement each other, whether the Luck Pillars move in a compatible direction, whether each person's useful gods support the other. A Day Branch harm is one signal, not a verdict.

That said, a Day Branch harm does have a recognizable pattern in relationships: the two people tend to experience a kind of quiet, low-grade friction in day-to-day life. Not dramatic fights, but a persistent sense that something is slightly off — hard to name, and tiring over time. The folk term for this is "mutual silent wearing-down," which I think is fairly accurate.

Yin-Si harm pairs often show a subtle power struggle over who leads — both have strong opinions, but neither states them directly, so friction hides in everyday decisions. You-Xu harm pairs sometimes present as one person feeling vaguely "pressed down" by the other, with neither party able to identify exactly why.

None of this is inevitable. These are simply patterns that show up with somewhat higher frequency in these harm combinations. Whether a relationship thrives ultimately depends on personality, communication habits, and the concrete circumstances of the people involved. BaZi (Four Pillars of Destiny) is one reference lens, not the whole picture.

Can the Six Harms Be Neutralized? What Does Folk Tradition Suggest?

There is a traditional saying: "harm is resolved when a combination arrives." The idea is that if another branch appears in the chart or in the year's flow that forms a Six Combination with one of the harming branches, the harm's force is diluted. For instance, with Zi-Wei harm: if Chou is present in the chart, it pulls Zi into a Zi-Chou combination, and Zi's "attention" shifts away from Wei, weakening the harm. This logic holds technically, but in practice it is difficult to engineer deliberately. It mostly depends on whether a person's natal chart already contains that kind of natural buffer.

Folk tradition also offers Feng Shui cures or date selection remedies — placing certain objects in specific positions in the home, or avoiding important decisions on harm-indicated days. I would not recommend taking these too seriously. The Six Harms already carry limited weight within the BaZi (Four Pillars of Destiny) system, so designing special countermeasures around them is a bit like treating a minor draft with elaborate construction. Worse, it can create a habit of attributing every problem in a relationship to the Six Harms, which does more harm to the relationship than the chart ever would.

If the Six Harms genuinely concern you in the context of a relationship, the more practical approach is to have an experienced practitioner read both charts as a whole — looking at the full Synastry picture — rather than isolating Liu Hai and asking about it alone. The Six Harms are a seasoning in the recipe, not the main dish.
