Ancient concubines make mistakes, why should they take off their pants and spank their asses?

This was the family rule of a large family in the Ming Dynasty to chastise a concubine.

(Order the concubine) lying on the couch, remove the lower skirt and pants, with a bamboo plate to beat (the concubine's) buttocks five or six times. The position of the spanking should be no lower than the place where the two femurs are separated (the crotch), and no higher than the tailbone.

Ancient women had a very low status, especially those who were concubines. They were just tools for procreation. Many concubines, even if they had already given birth to children, still needed to take down their pants and be beaten on their bare buttocks in front of their male masters and mothers when they made a mistake, without any dignity. As to why it was judged that this was not a beating of the maidservant but of the concubine, it was because of "lying on the couch". Lie down on the bed couch is the master of the male "pillow people" only have "treatment", often avoid people. If an ordinary servant girl makes a mistake, she will not even get such favorable treatment. And in full view of the public, lying on the bench (or on the ground) directly on the big board chastisement. Imagine the maids are unmarried women, blamed in public, natural face. The other maids are also "kill the chicken to warn the monkey" role.
