“姑”、“舅”二字，在今天都是单纯的亲属称谓：“姑”指父亲的姐妹，“舅”指母亲的兄弟。但在古代“姑”“舅”除了以上的意义之外，还有其他含义。“姑”除指父亲的姊妹外，又是儿媳对婆婆的称呼，《尔雅》中有“妇称夫之母曰姑”；亦是女婿对岳母的称呼，《礼记·坊记》? The words “unclear” and “舅” are simply relatives in today’s appellation: “姑” refers to the father’s sister, “舅” refers to the mother’s brother. However, in addition to the above meanings, there are other meanings in ancient times. “Jun” refers to the father’s sister, but also the daughter-in-law’s call to her mother-in-law, “Er Ya” in the “women call the mother’s aunt”; also the son-in-law’s mother’s call, “Book of Rites,” remember?
