Useful God versus Favorable God (用神與喜神的區別)
Distinguish the phase or function needed to solve the chart’s leading problem from a phase that supports or benefits that solution under stated conditions.
Overview
Useful God versus Favorable God (用神與喜神的區別) distinguishes a necessary corrective or organizing function from a supportive role that helps the chart or protects the Useful God. Usage varies by school, so a page must define its convention. Under a common hierarchy, the Useful God addresses the leading structural need, while the Favorable God generates, protects, extends, or complements it. Neither label is permanent outside the stated method and layer.

Declare the terminology convention
State whether the adopted school separates 用神 and 喜神, and how each role is assigned.
This prevents apparent disagreement that is actually a vocabulary difference.
- Name the school convention.
- Keep definitions stable within the page.
Trace the primary and supporting functions
Show the leading problem and how the Useful God addresses it, then show how the Favorable God supplies, protects, mediates, or extends that route.
If the support has no connection to the primary function, do not label it favorable by association alone.
- Map both function paths.
- Reject unsupported association.
Separate natal roles from timing availability
A period can reveal or obstruct either role without changing their natal definitions.
Report natal selection, period operation, and confidence in distinct fields.
- Preserve natal roles.
- Time-bound period effects.
Avoid permanent lucky-element labels
A Favorable God is not safe in unlimited quantity, and a Useful God does not guarantee money, health, relationships, or success whenever it appears.
Both labels remain conditional technical roles.
- No more-is-always-better rule.
- No event guarantee.
