history
Derived from 《仪礼·丧服·子夏传》 - 妇人有三从之义 ('a woman has the duty of three obediences: unmarried, obey her father; married, her husband; widowed, her son') - and 《周礼·天官》 on the four virtues for women: 妇德 (morality), 妇言 (proper speech), 妇容 (proper bearing), 妇功 (skill at needlework). Now used almost exclusively in critique.
