[Online Tool] What Do You Call Your Dad's Uncle's Son? Chinese Kinship Title Lookup

Chinese New Year is the annual family quiz that most Chinese people never quite pass.

Great-aunts, maternal uncles, paternal cousins, in-laws of in-laws… most people grew up just mimicking what adults said, without ever understanding the underlying relationships. The moment things get one step removed, it's a blank.

Toolshu's Chinese Kinship Title Calculator lets you input a relationship chain and instantly tells you what to call that person.

How to Use It

Work through the relationship chain step by step, starting from yourself.

For example, to find out what to call your dad's older sister's son:

Select Dad → Older sister → Son

The tool immediately gives the answer: 表哥 (biǎo gē) if he's older than you, or 表弟 (biǎo dì) if he's younger.

It also shows how that person should address you in return — both directions at once.

Why Is the Chinese Kinship System So Complex?

This puzzles many non-Chinese speakers. In most Western languages, "cousin" covers everyone. In Chinese, every relationship gets its own specific term. The logic runs deep:

Paternal and maternal lines are strictly separated. Relatives on the father's side use 堂 (táng); relatives on the mother's side use 表 (biǎo). So a 堂哥 is the son of your father's brother, while a 表哥 could be the son of your mother's sibling, or of your father's sister.

Gender is always specified. Your father's older brother is 伯父 (bófù); his younger brother is 叔父 (shūfù). Your mother's brothers are all 舅舅 (jiùjiu), but your father's sisters are 姑姑 (gūgu) while your mother's sisters are 阿姨 (āyí).

Relative age is embedded in the title. Even within the same generational relationship, whether someone is older or younger than you changes what they're called.

This system is remarkably precise — and precisely because of that, most people only know the handful of titles they encounter regularly. Anything slightly unusual and it becomes a blank.

A Few Classic "Brain-Twisters"

姑父 (gūfù): The husband of your father's sister. Not a blood relative, but has a formal title.

舅妈 (jiùmā): The wife of your mother's brother. Also not a blood relative, but equally formal.

连襟 (liánjīn): Two men who married sisters — they call each other 连襟. Most people have heard the word but can't explain the relationship.

妯娌 (zhóuli): The wives of brothers — they use this term for each other. Same idea.

外甥 vs 侄子: Your sister's son is 外甥 (wàisheng); your brother's son is 侄子 (zhízi). Paternal line uses 侄, maternal line uses 外甥.

Do Modern Families Still Need to Know This?

With smaller family units, many of these titles come up less often. But they still surface every year — at New Year gatherings, weddings, funerals, and family events.

Using the right title is basic courtesy. Using the wrong one gets you corrected by an elder, sometimes publicly. Better to look it up in advance than to guess on the spot.
