Interpretation of Er Ya Qin Shi: "A woman calls her husband's father an uncle and her husband's mother an aunt. It means that a woman (married woman) calls her husband's father "uncle" and her husband's mother "aunt".
The completion time of Erya is still controversial, but it will not be later than the Eastern Han Dynasty. In the fourth chapter of Erya, Interpretation of Relatives, lexicographers listed and explained a large number of kinship terms in the Eastern Han Dynasty and before.
For example, a daughter-in-law should be called "uncle" when she sees her father-in-law, and "aunt" when she sees her mother-in-law; In-laws who are alive are called "Jun Jiu" and "Gu Jun"; When in-laws die, they are called "an uncle" and "an aunt".
