CORE DEFINITION

Sheng Nu is a derogatory term for older single women. The All-China Women's Federation defines "leftover women" as unmarried women over the age of 27. The term is mainly used in mainland China, but also in India, North America, and other parts of Asia. In Japan, older unmarried women are referred to as "women thrown away by men" and also as "3S women": Single, Seventies (mostly born in the 1970s), and Stuck. There was once a popular saying online that unmarried women aged 25 to 28 are called "junior leftover women" or "leftover fighters"; those aged 28 to 32 are called "intermediate leftover women" or "leftover guests"; those aged 32 to 35 are classified as "senior leftover women"; and those over 35 who are still unmarried are respectfully called "the Great Sage, Equal to Heaven" (a pun on the Chinese classic Journey to the West). Older single women are labeled with various age tags, and the image of "leftover women" is not limited to this; in this regard, the news media has played a role in fueling the fire, as media exposure continuously constructs the public's perception of "leftover women."

Anchor fast decisions

This label reflects a structural mismatch: the rise in women's education and economic independence clashes with the traditional "male-strong, female-weak" marriage gradient (preference for homogamy or hypergamy); combined with the sex ratio of the marriageable population, urban living costs, and matching frictions in the marriage market, some highly educated urban women marry late or not at all. It is a product of social transformation, not personal deficiency.
