Gemini for BaZi: How a General Dialogue Model Generates Text

Gemini is a general-purpose conversational model that produces text token by token. The annotations on a Chinese-metaphysics chart are, for such a model, simply written output like any other passage; they are not the result of a separate calculative process. This matters when Gemini算八字 is used to report items such as 旬空, because the item should be checked against a fixed correspondance rather than accepted as a computed result. The following sections explain how 旬空 is derived, why it can be verified directly, and what its presence or absence indicates about the reliability of the chart.

旬空是一项可以直接判对错的标注

旬空, often called void branch or empty branch, is one of the few items on a bazi chart that can be marked right or wrong without reference to a school of interpretation. It follows from a fixed mapping within the sexagenary cycle. Once the day pillar is known, the corresponding void branches are determined by position in the cycle, not by doctrinal preference. For this reason, two practitioners using different interpretive traditions should still report the same 旬空 for the same day pillar. If they do not, at least one report is incorrect.

This makes 旬空 useful as a checking item. Many other annotations on a chart, such as the strength of an element or the weight of a combination, depend on method and context. 旬空 does not. It can be used to test whether a tool is producing a coherent chart layer, or merely generating plausible-looking text around the chart. A tool that fails on a fixed correspondance is likely unreliable even where its prose sounds fluent.

空亡挂在日柱所在的旬上

The sixty sexagenary pairs are divided into six blocks, or 旬. Each 旬 contains ten 干支 pairs, moving through the ten heavenly stems in order while the earthly branches also advance. Because there are twelve earthly branches but only ten stems in one full stem cycle, each 旬 leaves two branches outside its sequence. Those two branches are the 空亡 of that 旬.

For a bazi chart, the relevant 旬 is the one containing the day pillar. The four pillars each have their own 干支, but 空亡 is not calculated separately for year, month, or hour. It is assigned to the chart as a whole based on the day pillar. In other words, one first locates the day pillar within its 旬, then identifies the two branches that do not occur in that 旬. Those two branches are the chart’s 空亡.

一个旬对应两个空亡地支

Each 旬 has exactly two void branches. For example, the 甲子旬 runs from 甲子 to 癸酉. The branches present are 子，丑，寅，卯，辰，巳，午，未，申, and 酉. The two absent branches are 戌 and 亥, so 戌 and 亥 are the 空亡 for any day pillar within the 甲子旬. The same principle applies to the other five 旬: the two branches not reached within the ten-pair sequence become the void branches.

Because the mapping is fixed, a given day pillar always falls in exactly one 旬 and therefore always yields the same two void branches. There is no interpretive step between the day pillar and the two branches. The only prerequisite is that the day pillar itself be correct. From that point, the void branches follow mechanically.

让工具报出空亡再逐柱比对

A practical way to check a chart produced by Gemini or another model is to ask it to report the 空亡 explicitly. Then compare the reported void branches with the day pillar. After confirming the day pillar, one can derive the expected void branches independently and see whether the tool’s answer matches. Next, examine each of the four pillars in turn and note which earthly branches fall within the void pair. Those are the pillars whose branch is said to fall void.

The site’s free charting function includes 旬空 information alongside 纳音. When the day pillar is settled, the void branch pair is also settled. This means the expected answer can be obtained from a fixed reference without relying on another language model. The checking sequence is: first confirm the day pillar, then confirm the two void branches of its 旬, and finally see which branches among the four pillars are hit. If the tool’s report passes this sequence, the annotation layer is at least internally consistent for 旬空.

日柱错时这一项跟着错

The relationship between the day pillar and 空亡 is one-directional: the day pillar determines the void branches, but the void branches do not independently confirm the day pillar. If the day pillar is wrong, the void branches derived from it are also wrong, because they are calculated from the wrong 旬. In that case, the error is not isolated to the 空亡 field; it is inherited from the day pillar.

For this reason, checking 空亡 alone is not enough. One must first verify the day pillar against a reliable calendar source. If the day pillar is correct but the reported void branches are wrong, the tool’s annotation layer is unreliable. That is a specific and meaningful failure. If the day pillar itself is wrong, the void branches are invalid from the start, and the appropriate response is to return to the day pillar and correct it before assessing anything else.

空亡在不同方法里的分量差别很大

Although 旬空 is fixed in derivation, its interpretive weight varies widely across methods. Some systems treat the void branch as a significant condition affecting a pillar or a ten-god relation. Others give it a minor role, or treat it mainly as a qualifier rather than a central factor. For this reason, the presence of a void branch in a chart should not by itself be turned into a strong conclusion about a person’s situation or tendencies.

The function of 旬空 in this context is diagnostic rather than predictive. It shows whether a tool’s chart annotations can be verified against a stable reference. It does not, by itself, provide a sufficient basis for judging the overall quality of a reading. A tool may report 旬空 correctly and still produce unreliable interpretations elsewhere; conversely, a tool may produce fluent prose while failing this simple check. The value of 旬空 lies in its testability, not in its standalone interpretive force.
