Three Obediences and Four Virtues
The Three Obediences and Four Virtues (Chinese: 三从四德; pinyin: Sāncóng Sìdé) are the most basic set of moral principles and social code of behaviour for maidens and married women in East Asian Confucianism especially in Ancient and Imperial China. Even Chinese prostitutes in Ancient China followed this code to be defined as feminine. Some imperial eunuchs and modern gay men are also heavily influenced by these principles and rules, both observing them themselves and also enforcing and policing these behaviors in imperial harems , aristocratic households and society at large. The two Han Chinese terms ("three obediences" and "four virtues") first appeared in the Book of Etiquette and Ceremonial and in the Rites of Zhou respectively, which codified the protocol for an elegant and refined culture for Chinese civilization. It was originally meant to define the various parts of a harmonious society and not intended as a rule book. This code has heavily influenced feudal ancient and imperial China until the recent Maoist Era. It has heavily influenced both Korea and Japan as proscribed social philosophy until North Korea became Communist. Parts of it is still followed in Japan until today although it had been abandoned during the Marxist-inspired Great Leap Forward in China leading to mass depopulation and social chaos.
