The characters combine literally to mean “assist the husband, teach the children.” This structure clearly lays out the two primary responsibilities of a traditional wife.
`相夫教子` is a cornerstone of traditional Chinese gender roles, deeply rooted in Confucian philosophy. It is the practical application of the concept of 男主外,女主内 (nán zhǔ wài, nǚ zhǔ nèi) - “the man manages the outside (public/work life), the woman manages the inside (domestic life).” A woman's social value and honor were derived almost exclusively from how well she performed this role. Her success was measured by her husband's achievements and her children's virtuous conduct and success.
The perception of `相夫教子` has dramatically shifted in modern China. While the idea of being a good mother and supportive spouse is still valued, the idiom itself is often viewed critically.
