Should You Match BaZi Before a Blind Date?

In Chinese practice, the question of whether one should first compare bazi before a matchmaking meeting, or xiangqin, is often asked as if it were a simple yes-or-no question. In fact, it is usually blocked by a practical problem: a proper bazi marriage comparison requires inputs that are often not available before a first meeting. The more useful way to handle the question is therefore to separate what can be done early from what cannot, and to understand what the method itself can and cannot support.

这个问题先卡在输入上

The idea of comparing bazi before xiangqin assumes that both people already know their full birth data and are willing to share it before meeting. In many real situations, one or both sides do not yet have the other person’s birth year, month, day, and hour. Sometimes only the year of birth, the Chinese zodiac animal, or a rough age is known. In those cases, hehun in the proper sense cannot yet be performed.

The issue is not that the method is secret or that the calculation is difficult. The issue is that marriage comparison is a cross-chart comparison. It compares the ganzhi relationships between two complete charts. If one side’s input is incomplete, the comparison cannot be made reliably. Asking whether to combine bazi before xiangqin is therefore often premature. Before deciding whether it should be done, one must first ask whether the required information actually exists.

合婚需要的两组完整出生信息

In method, hehun compares the ganzhi relationships between two charts. The main categories examined include he, chong, xing, hai, and po, as well as the generating and overcoming relationships between nayin. These comparisons are made across the two charts, not within one person’s chart alone.

To perform this comparison, each side’s complete birth information is required: year, month, day, and hour. This is because the hour is what determines the hour pillar. Without an hour, the chart has no hour pillar, and the cross-chart relations that depend on the hour pillar cannot be assessed. A missing hour does not merely reduce precision; it changes the structure of the comparison.

The site’s position is that when a birth hour is not publicly known, the chart is interpreted using only three pillars. That means the year pillar, month pillar, and day pillar are used, and the hour pillar is not guessed or filled in. The resulting reading is explicitly a three-pillar reading. In that form, it may still reveal certain tendencies, but it is not the same as a full four-pillar hehun.

This matters directly for the question of xiangqin. Before a first meeting, the two people often know almost nothing about each other. One side may know only the other person’s age, or perhaps the zodiac animal. That is not enough to build a chart, let alone to compare two charts. Even if both birth dates are known, the birth hours may not be. In that case, the comparison would have to be limited to three pillars on one or both sides, and the result would have to be read with that limitation clearly in mind.

只拿到生肖或年份时能做什么、不能做什么

When only a zodiac animal or a birth year is available, a person may still want some early indication of compatibility. At that level, one can sometimes speak in broad terms about the animal sign or the year branch. But this is not the same as hehun. The method of marriage comparison does not reduce two people to their zodiac animals. A proper comparison works with the full set of four pillars on each side and with the relations between them.

With only a year or an animal sign, one cannot examine the month pillar, the day pillar, or the hour pillar. One cannot assess the day master, the ten gods, the branch relations across charts, or the nayin relations. Most of the information that gives hehun its descriptive content is simply absent. Therefore, any statement made from zodiac signs alone should not be presented as a bazi marriage comparison.

This does not mean that no observation can be made. A person can, for example, note that a certain year branch has a chong relation with another year branch. But a single branch relation is only one small piece of a much larger picture. It cannot support a conclusion about whether two people should marry, nor even a reliable description of how their personalities would interact.

合婚结果的性质：整理差异，不是筛选人

When a full comparison can be made, the output is usually used to sort out differences between the two people. These differences typically appear in three areas: how each person expresses temperament, how each person orients toward resources, and how each person prefers to use time and pace. The comparison brings these differences into view so that the two people can discuss them.

The result is not a pass or fail test. It is not a filter that says one person is suitable and another is not. The method produces a description of tendencies. It may say that one side tends to move quickly while the other tends to delay, or that one side expresses conflict directly while the other withdraws. These are patterns, not verdicts.

The engine can output the four pillars in ganzhi form, the ten gods derived from the heavenly stems and hidden stems, the relations between stems and branches, the relative strength of the day master, and the shensha. These outputs give material for interpretation, but they do not by themselves decide whether a marriage should happen.

It is especially important to say clearly what hehun cannot do. It cannot determine whether two people should marry. It cannot predict that a marriage will fail. It cannot certify that a marriage will succeed. Any use of the result as a definite conclusion goes beyond what the method itself can support. The same applies to the reverse use: rejecting someone before meeting because one pillar relation looks difficult is also an overreach.

把顺序放对之后的做法

Once the limitation on inputs is accepted, the practical order becomes clearer. Before xiangqin, if only the zodiac animal or age is known, one should not attempt a full hehun. If both sides are willing to share full birth data before meeting, a three- or four-pillar comparison can be prepared, but only with the understanding that the output is descriptive.

If the birth hour is missing, the site’s rule is to use three pillars. That limitation should be stated alongside any reading. The result can still be useful for noticing broad tendencies, but it should not be treated as a complete marriage comparison.

After meeting, if the two people are interested and willing to share full birth information, a fuller comparison can be made. At that stage, the comparison may help them organize the differences they have already begun to notice. The purpose is not to replace observation or conversation, but to give a structured way of seeing where friction and complementarity may come from.

The question of whether to combine bazi before xiangqin is therefore not best answered with a simple yes or no. The method requires complete inputs, compares charts rather than zodiac signs, and produces tendencies rather than decisions. If the birth data are not yet available, the correct answer is that the comparison cannot yet be done. If the data are available and both sides agree, the comparison may be done, but its result should be held lightly. In this sense, the better question is not whether one should check first, but whether one has enough information to check at all, and whether one understands what the check can and cannot say.
