Zi Wei Compatibility Chart: Reading Two People's Twelve Palaces Side by Side

Before a friend's wedding she spread the two printed Zi Wei charts on the table side by side and asked me where to look first. I studied them for a while and told her the truth: don't look at the stars yet, look at how the compartments correspond — Spouse Palace against Spouse Palace, Life Palace against Life Palace. She paused, and said she had not known it could be read that way.

What a Zi Wei Compatibility Chart Looks At

A Zi Wei compatibility chart matches two people's twelve palaces area by area and observes how the two sides' conditions within the same area interact: whether one person's strength lands exactly where the other is weak, whether one person's four transformations keep falling on places the other cares about. The emphasis is on the interaction itself rather than on labelling the two people, and it does not issue a verdict of suitable or unsuitable either.

Information to prepare: both people's accurate birth year, month, day and hour. Zi Wei charts are sensitive to the hour; with the wrong hour the palaces shift as a whole and the comparison loses its meaning.

The Order of Comparison

  1. Match the Life Palaces first: look at the two people's basic style and outward presentation. This step sets the tone for the whole comparison.
  2. Then match the Spouse Palace and its San Fang Si Zheng (the three directions and four positions): this is the group most often focused on. Besides the stars inside each person's Spouse Palace, read its San Fang Si Zheng as well, because a star's strength is often expressed through the way it is combined.
  3. Look at where the four transformations land: which palace of the other person's chart one person's birth-year or major-period transformations fall into is often the situation most likely to recur in the interaction.
  4. See whether the major fortune cycles are in step: whether the two people's current major-period rhythms fit — one in a rising stretch and the other in a stretch of sorting things out will naturally interact differently.

Comparing Three or More People

Comparing three or four people is not a matter of adding up pairs. The usual approach is to find the shared intersection first: how all the Life Palaces are distributed, which areas are touched by common transformations — and then to look at the division of roles within each pair. The more people involved, the more the conclusion should converge on the level of how to get along, rather than reaching toward specific events.

Origins

Zi Wei Dou Shu's earliest systematic text is the Ming-era Quan Shu of Zi Wei Dou Shu, and its twelve-palace structure and four-transformation rules are still in use today. A two-person comparison is not an original practice from those texts; it is a later extension that applies the palace system to observing relationships, which is precisely why it has to be used and bounded at the same time.

Its Limits

Scope first: a Zi Wei comparison reads area-by-area interaction and rhythm, does not judge the outcome of a relationship, and is not suited to making marriage decisions. Then the input: if the hour is inaccurate the palaces are displaced as a whole and the comparison loses its ground. Finally the conventions: auxiliary-star selection and four-transformation rules differ between schools, so both charts have to be cast with the same conventions, or the comparison will show differences that are not real — the difference sometimes comes from the casting method itself rather than from the two people.

What the Result Looks Like

You get two twelve-palace charts set side by side, with the interaction explained palace by palace: which areas fill each other in, which areas tend to repeat the same friction, whether the current major-period rhythms fit. It is best to read from the Life Palace and the Spouse Palace first, then move on to the specific areas.

Three Common Misreadings

Treating the Spouse Palace as the conclusion. The Spouse Palace describes the tendencies and handling style in this kind of relationship, not its outcome. Looking at one combination and declaring an ending is the most common misreading.

Mixing two sets of conventions. Casting one person's chart with school A's auxiliary-star selection and the other's with school B's conventions produces differences that are partly false — caused by the conventions rather than by any real distinction between the two people.

Reading only one chart. A comparison is a conversation between two charts. Fixing your eyes on one person's chart makes it easy to read an interaction problem as a one-sided personality problem.

How to Read the Synchrony of Major Periods

Besides the palaces, look at where each person currently stands in their major-period rhythm. If one is in a stretch where their structure runs strong and the other is in a stretch of sorting out and adjusting, the energy the two show outwardly will naturally differ.

This layer explains why your attitudes to the same thing have been so far apart lately — it puts the difference between the two of you on a timeline, instead of reducing it to something wrong with either person. When reading, look first at which area each person's current major fortune cycle falls in, then set the two positions side by side.

What to Do With the Conclusion

A conclusion that stops at where the two of you are different has limited use. A more practical move is to turn it into two or three executable actions:

Write down the areas where friction repeats — the rhythm of spending, the way each of you deals with your own family — and agree on a concrete communication mechanism, such as reconciling the accounts once a month or talking through arrangements before every holiday. As for the complementary parts, you can divide the labour deliberately when a joint decision comes up: who is better at taking the lead, who is better at wrapping up, so that structural differences become the basis for dividing tasks.

One reminder: this kind of conclusion is meant to be read and discussed by the two of you together, not carried by one person as proof that the other is wrong. The latter almost always escalates the friction, and that is the most common way a compatibility chart is put to the wrong use.

FAQ

Q: Do both people's birth hours have to be accurate? Ideally yes. If only one is accurate, work only with the parts of the palace comparison that are less affected, and note the range of uncertainty in the conclusion.

Q: If the Spouse Palace is not good, does that mean we should not be together? No. The Spouse Palace describes the tendencies and handling style in this kind of relationship; it does not determine the outcome. How you get along after seeing the hint is down to the people involved.

Q: Can two people's charts come out completely at odds? They can, and it is usually because the two people have their own rhythms in different areas. The value of a comparison is to make that difference clear, not to manufacture opposition.

Q: Should it be read together with a BaZi compatibility chart? You can. A BaZi comparison leans toward structure and complementarity, a Zi Wei comparison toward areas and rhythm; they look from different angles. If you only choose one, choose by the question you care about more.

Q: What if neither person's Spouse Palace is strong? A weaker Spouse Palace does not mean a bad relationship. The usual reading is to look for supporting forces in the San Fang Si Zheng, then check whether the current major fortune cycle falls in this area. The conclusion should land on how to get along with less effort, not on suitable or not.

Q: Does a comparison need a birthplace? It is advisable. The birthplace affects the conversion of the hour and the conventions used in casting, especially for births close to the boundary between double-hours.

Q: If the two charts share a similar weakness, will they amplify each other? That is possible: the same structural shortfall can easily put both people into the same pit at the same time. This is exactly where spelling the rules out in advance pays off — knowing where you are likely to stumble together means you can agree beforehand on how to handle it.

Where to Start

If both of you have accurate birth information, you can go straight into the process here: describe the direction you want to understand in plain language, and the system will suggest a method. You can specify the Zi Wei compatibility chart, then see the two charts and the area-by-area comparison, and export them if you want to keep them. In the Zhanbu Mizhi process, the comparison is derived from data analysis, not applied from fixed conclusions.
