Rong Kaiji
Etiquette begins with respect for husband and wife, and distinguishing the inner and outer parts of the palace. Men live outside, women live inside, and the palace is deep and the gates are strong, with gatekeepers guarding it. Men do not enter, and women do not leave. Men and women do not use the same shackles, dare not hang on the husband's shackles, dare not hide in the husband's box, and dare not bathe together. When the husband is not at home, the pillow, box, mat, and quilt are hidden. The young serve the elder, the humble serve the noble, and everyone is the same. The etiquette of husband and wife only lasts until the age of seventy, and they share the same shackles. Therefore, even if the concubine is old, she must have sex with him for five days before she reaches fifty. The one who is about to give birth to a child, washes his head and washes his clothes carefully, combs his hair, puts on a hairpin, brushes his hair, and wears a collar, tassels, and sandals. Even maids and concubines must dress and eat after the elders. If the wife is not at home, the concubine dare not give birth to a child at night.
