People in Henan call women eldest sister-in-law and older women. In Henan dialect, eldest sister-in-law is usually used to address older women, especially married women. There is a saying that the origin of this title is that in rural society, married women are usually responsible for housework and family care, so they are regarded as the "big sister" of the family, that is, the head of the family. In addition, this title is also related to the tradition of respecting the elderly in Henan culture.
