What Is Tiger Ox Galloping to Snake (虎牛奔巳) in BaZi?
Learn the Xin-Gui day, Yin-Chou, absent-Si, You-retention and Shen-Si blocker rules, plus the Tiger Ox pattern name variant.
Overview
Tiger Ox Galloping to Snake is the standardized English label for 虎牛奔巳. The transmitted rule starts with a Xin or Gui Day Master and requires both Yin and Chou: Yin is read as punishing toward an absent Si, while Chou connects to Si, so hidden Bing or Wu can be interpreted as Officer for Xin or Gui. A visible You is used to retain the invited target; visible Shen or Si ends the stated route, and a directly established Wealth or Officer structure takes precedence. One source heading reads 虎午奔巳, but its condition, examples and verse all use Yin and Chou—the tiger and ox—so OpenFate records the heading as a textual variant rather than changing the rule. The chart never gains a literal Si, Bing or Wu, and OpenFate has no detector for this pattern.

The rule is built from Xin or Gui, Yin and Chou—not Wu
The source assigns different Officer targets to the two Day Masters: Bing Fire for Xin and Wu Earth for Gui, both hidden in Si. It then treats Yin as the punishment side and Chou as the combination side of a remote link to that absent Si. You is an additional retaining branch, not a replacement for Yin or Chou.
The received heading 虎午奔巳 conflicts with the condition and verse, which both name Yin and Chou. Because Yin is tiger and Chou is ox, the workbook uses 虎牛奔巳 while retaining 虎午奔巳 as a source variant. This editorial normalization does not create a new rule.
- Require a Xin or Gui Day Master plus both Yin and Chou.
- Keep the heading variant visible in source notes and aliases.
Si must remain absent and ordinary structures still lead
Visible Si fills the remote target, and the source also excludes visible Shen. If the original chart already contains a usable Wealth or Officer structure, the later note says to judge that direct structure instead of this indirect route.
The old examples illustrate the route but do not prove a general algorithm for every Xin or Gui chart. Missing Yin, missing Chou, uncertain retention or a source-version conflict must fail closed rather than be repaired by inference.
- Do not count an inferred Si as chart data.
- Prefer direct Wealth, Officer and month-command evidence.
OpenFate verifies visible relations without inventing the target
OpenFate can calculate the Day Master, Yin, Chou, You, Shen and Si, their hidden stems, Ten Gods and ordinary branch relations. Those deterministic facts are useful for studying the transmitted rule.
OpenFate does not insert Si, Bing or Wu and does not output Tiger Ox Galloping to Snake. A future detector would need a versioned title, a strict absence state, the Xin-Gui Officer map, retention rules, precedence and counterexamples. Existing reports remain unchanged.
- Separate computed chart facts from remote-link commentary.
- Do not publish a positive result while the title or condition is unresolved.
The historical name does not promise rank or success
This is a historical interpretive model. It cannot establish examination success, office, status, income, wealth or a favorable life outcome.
Career, financial, legal, relationship, health and safety decisions require current evidence and qualified advice, not a rare pattern label.
- Exclude rank, wealth and timing guarantees.
- Use the entry for terminology and source study only.
