The 婆媳关系 (póxí guānxì, mother-in-law/daughter-in-law relationship) is a major theme in Chinese family life and TV dramas. Traditionally, a new bride moved into her husband's family home and was under her 婆婆's authority.

婆婆 is specifically the husband's mother. The wife's mother is 岳母 (yuèmǔ, formal) or 丈母娘 (zhàngmǔniáng, colloquial). Mixing these up is a common mistake for learners.
