Branch Gong Hui Lookup: Directional Arch Combinations in BaZi

What Gong Hui Means

Gong Hui is a directional arch pattern. It appears when the first and last branches of a directional trio are adjacent in the natal four pillars while the middle branch is absent. Deep Oracle reports it as a separate branch-interaction kind because the rule is narrower than a full directional trio.

Deep Oracle Rule

The engine reports Gong Hui only inside the natal four pillars, and only for adjacent pillar positions: year-month, month-day, or day-hour. Luck pillars, annual pillars, monthly pillars, and daily pillars do not create Gong Hui in this detector.

Gong Hui is also not treated as a completed San Hui directional trio. The output keeps transforms=false, so it is a structural note rather than a transformation result.

Common Questions

Is Gong Hui the same as San Hui?
No. San Hui requires all three directional branches. Gong Hui has only the first and last branches, with the middle branch absent.

Why is this rule conservative?
The use of Gong Hui varies by school. Deep Oracle keeps it narrow by requiring natal adjacency and by not treating it as full transformation.

How is Gong Hui different from Gong He?
Gong Hui comes from directional trios. Gong He comes from San He trios. The engine records them as different branch-interaction kinds.
