The Servants Palace, nu pu gong, read along the lower jawline and the sides of the chin, preserves a piece of social history more directly than most of the twelve palaces do. Its historical claim named a person's fortune specifically with servants, a category that presumed a household economy organized around masters and the subordinates working under them, the kind of social structure Ming era compilers of the Shenxiang quanbian would have taken for granted rather than needed to explain. Contemporary practitioners have not discarded the palace, they have reread it, treating it now as covering employees, staff and anyone working under a person's direction, a reading that keeps the palace's underlying logic, fortune with people one has authority over, intact while updating the specific social relationship it describes.
A full, well fleshed jawline here is read as a sign of loyal subordinates and ease in managing others, while a thin, sharp or receding jawline is read as trouble commanding loyalty from staff. The palace stands as one of the clearer cases in the whole system of a fixed piece of interpretive vocabulary surviving a real change in the society that first produced it, carried forward by reinterpretation rather than by the underlying social relationship staying constant.
