Parent-child compatibility
Check if parents' sexagenary cycle is compatible with child's birth year.
Note: born in Jan–Feb before Lunar New Year? You belong to the previous lunar year — pick that year instead.
How compatibility works
- Trinity (Tam Hợp): 3 chi forming a harmonious group — Tý-Thìn-Thân, Sửu-Tỵ-Dậu, Dần-Ngọ-Tuất, Mão-Mùi-Hợi
- Pair (Lục Hợp): Pairs that complement — Tý-Sửu, Dần-Hợi, Mão-Tuất, Thìn-Dậu, Tỵ-Thân, Ngọ-Mùi
- Conflict (Tứ Hành Xung): 4 groups of conflicting chi — Tý-Ngọ-Mão-Dậu, Sửu-Mùi-Thìn-Tuất, Dần-Thân-Tỵ-Hợi

What are Tam Hợp, Lục Hợp, and Tứ Hành Xung?
Tam Hợp = three branches in harmony (90/100). Lục Hợp = two complementary branches (80/100). Tứ Hành Xung = four conflicting branch groups; direct opposition is called Trực Xung (10/100). This is a folk-tradition model.
Is low compatibility a problem?
In tradition, high compatibility correlates with family harmony. However, marriages and parenting depend far more on love, understanding, and presence than on Can Chi alone.
Does it factor in Five Elements (ngũ hành)?
Yes — the score combines branch compatibility (60%) with Five Element compatibility (40%) for a more nuanced verdict.
