Come uninvited, disturb me, and exchange gossip for drinks, focusing on cultural creation. Welcome to pay attention to the subject of exchange: how complicated is the relationship between relatives? Answer: then let&;s talk about the relationship between relatives first: take yourself as the center, first look up at parents who gave birth to themselves, and father&;s father is called grandfather, that is, grandfather; Grandparents&; wives are called grandmothers, that is, grandmothers have brothers, and grandfathers&; brothers are also their own grandfathers. Generally, grandfathers are called grandfathers and grandfathers … Grandfathers&; fathers are called great-grandfathers, and great-grandmothers&; wives are called great-grandmothers. However, in real life, there are few families with four generations living under one roof, which we call great-grandfathers: grandfathers, grandmothers are grandfathers, grandfathers are grandfathers, and grandfathers are grandfathers. Namely: father, ancestor, Zeng, Gao, Tian, Lie, Tai, Yuan and Nose. The book says: because people are pregnant, the nose takes shape first, so the originator is the ancestor. Looking down from the ancestral temple, one&;s son, daughter&;s son&;s wife, son&;s son&;s grandson, son&;s daughter&;s grandson&;s husband&;s son-in-law, daughter&;s son&;s grandson, daughter&;s granddaughter&;s children call themselves father, grandchildren call themselves grandfathers, granddaughters call themselves grandfathers&; sons, grandsons are grandsons, grandsons are great-grandchildren, great-grandchildren&;s sons are great-grandchildren, and great-grandchildren&;s sons are grandsons. Namely: Zi, Sun, Zeng, Xuan, Lai, Bi, Still, Yun and Er. The book says: those who listen to their grandchildren call their ancestors far away, and they are only heard by their eyes and ears. A future child of a big family came home from school and asked his parents, why don&;t I have cousins, uncles, aunts, uncles and uncles? This is more embarrassing … Where do you get so many relatives in a family of three … If the father is an only child, the child will have no uncles, cousins, aunts, uncles and cousins, and if the mother is an only child, the child will have no uncles, aunts, cousins and uncles, and menstruation. If the child is an only child, he has no brothers and sisters. If the child marries/marries an only child, there will be no brother-in-law and sister-in-law, and then a grandson will continue to be an only child. Then within three generations, there will be only a family of three lineal relatives. Then the child asks you, Mom and Dad, what are uncles, aunts, uncles and cousins? Then you can only tell him that once, the family was very big and lively, and there were many people who called them relatives. …
