For parents, the eldest son bowed his head. When a senior official offers condolences, he must bow his head even if he is in mourning. A woman bows her head for her husband and the eldest son, but not for the rest. A male head must have the same surname as the head of the family, while a female head must have a different surname. A descendant of a father does not need to mourn for his mother. To be close to relatives, three is five, and five is nine. Kill the upper ones, the lower ones, and the side ones, and the close relatives are complete. The king shall offer sacrifices to the ancestor from whom he was born, and marry him with his ancestor, and establish four temples. The same is true for a concubine's son to be king. The son who is separated from the other is the ancestor, the one who succeeds the other is the clan leader, and the one who succeeds the niece is the minor clan leader. After five generations, the clan leader is moved to the clan leader, and he is the one who succeeds the great-grandfather. Therefore, the ancestor is moved to the upper one, and the clan leader is moved to the lower one. Respecting the ancestors means respecting the clan leader, and respecting the clan leader means respecting the ancestors and the niece. A concubine's son does not offer sacrifices to the ancestors, so that his clan leader is clear. A concubine's son is not beheaded for the eldest son, because he does not inherit the ancestors and the niece. A concubine's son does not offer sacrifices to the deceased or the one who has no descendants, because the deceased or the one who has no descendants is buried with the ancestors. A concubine's son does not offer sacrifices to the niece, so that his clan leader is clear. Love your relatives and respect your elders. The difference between men and women is the greatest of human nature.
