Chinese kinship terms and their cultural roots
Why are kinship terms so complicated?
China has one of the world's most complex kinship systems, shaped by millennia of patriarchal clan structure and Confucian ethics. Titles encode not just relation but seniority, age order, closeness and hierarchy — getting one wrong reads as rude.
The complexity peaks across Northern Han and Southern clan regions, each with dialect variants.
Elders (paternal)
- Father's father → 爷爷 (paternal grandfather); mother's father → 姥爷 (maternal grandfather)
- Father's mother → 奶奶 (paternal grandmother); mother's mother → 姥姥 (maternal grandmother)
- Father's elder brother → 伯父 (uncle); father's younger brother → 叔叔
- Father's sisters → 姑姑 (aunt) (their husbands → 姑父)
- Mother's brothers → 舅舅 (uncle) (their wives → 舅妈)
- Mother's sisters → 姨妈 (aunt) (their husbands → 姨父)
Same generation
- Cousins (father's side, male): uncles' sons
- Cousins (father's side, female): uncles' daughters
- Cousins (mother's side): children of aunts and uncles
- Husband: his father is 公公 and his mother is 婆婆 to you
- Wife: her father is 岳父 and her mother is 岳母 to you
Five Degrees & Nine Clans
Traditionally, the "five degrees of mourning" (五服) measured kinship closeness — count five generations up and down from yourself:
- 斩衰 (heaviest mourning): children mourning parents — three years
- 齐衰 (second degree): grandchildren mourning grandparents — one year
- 大功 (third degree): siblings and paternal cousins — nine months
- 小功 (fourth degree): great-uncles and their spouses — five months
- 缌麻 (lightest): distant clan kin and great-grandparents — three months
"Beyond the five degrees" means the relation falls outside the five-generation system — distant kin, today mostly a courtesy reference.
