| Rule | Romance | Friendship | Business |
|---|---|---|---|
| San He, Three Harmony (三合) | +28 | +30 | +36 |
Fixed animal elements add 8 (generating), 4 (same) or −6 (controlling), reduced to 35% for harmony, clash or harm relations. A Xing flag subtracts 10/8/12. Each score is rounded and limited to 15–98; the overall score is their rounded average.
