Virtue is established through disciplined control of the body's smallest movements: walk without turning the head, speak without parting the lips widely, sit without moving the knees, stand without swaying the skirt. Outward composure is treated as the visible form of inner purity, so regulating posture, gesture, and voice is the first step in forming character.
Men and women occupy distinct spaces and groups, and a woman should not peer over the outer wall or wander into the outer courtyard. Physical boundaries do the work of moral boundaries: by fixing where one may stand and look, the rule removes occasions for impropriety before any choice arises.
The etiquette and hospitality chapters direct a woman to keep her visits to other households brief and to serve tea properly when receiving guests. When her husband is away, she is to receive visitors courteously but with reserve.
The woman who rises at the fifth watch, dresses, and sets the day's work in motion keeps the household fed and orderly. The one still in bed when the sun is high leaves tasks undone and invites poverty and ridicule. Diligence is measured in daily timing, and neglect compounds from the first hour.
A woman must learn spinning, weaving, sewing, and food preparation regardless of her family's wealth, because skill in work secures the household against hardship and marks her as capable. Idleness is treated as a moral failing, not merely a practical one.
Household prosperity comes from storing grain, conserving resources, and saving small amounts steadily so they build into security. Waste in good years produces want in bad ones. The prudent manager plans across seasons rather than consuming according to present abundance.
A mother is responsible for instructing her children, directing sons toward study and training daughters at home in work and propriety. Indulgence corrupts, and when children turn out badly the blame falls on the mother's failure to teach. Upbringing is framed as a moral duty with a traceable line of responsibility.
Harmony with parents-in-law, husband, and sisters-in-law is achieved by yielding, avoiding quarrels, and not spreading gossip between family members. Gentleness is presented as a practical instrument for preventing the small frictions that break extended households apart.
