Recently, one of my friend told me that last time she backed to her hometown to attend a funeral. At there, she met hundreds of relatives. Yes, hundreds of people ... it is not a kidding.
In her family, the eldest person is her grandmother, who is already 94 years old. And the first son of the grandmother, 74 years old, already becomes a grand-grand-grandfather... That means there are 6 generations in this big family. 😱
This size of family is often appear in agricultural community. New baby can grow up to join the work in a short time. Compare with developed society, the cost of cultivating is much less. In the other word, getting married early and born many children can rich the community.
