The appellations of one's ancestors over eighteen generations

The so-called "eighteen generations of ancestors" refers to the members of one's clan spanning nine generations above and nine generations below oneself. The titles of the eighteen generations of ancestors going upwards are as follows: those who gave birth to oneself are called parents; the father's father is grandfather; the grandfather's father is great-grandfather; the great-grandfather's father is great-great-grandfather; the great-great-grandfather's father is heavenly ancestor; the heavenly ancestor's father is fiery ancestor; the fiery ancestor's father is supreme ancestor; the supreme ancestor's father is distant ancestor; the distant ancestor's father is original ancestor. That is: father, grandfather, great-grandfather, great-great-grandfather, heavenly ancestor, fiery ancestor, supreme ancestor, distant ancestor, original ancestor. The book states: Because a person's body begins in the womb and the nose is formed first, the original ancestor is considered the first ancestor. The titles of the eighteen generations going downwards are as follows: the father's son is called son; the son's son is grandson; the grandson's son is great-grandson; the great-grandson's son is great-great-grandson; the great-great-grandson's son is future grandson; the future grandson's son is Kun (pronounced kūn) grandson; the Kun grandson's son is successive grandson; the successive grandson's son is cloud grandson; the cloud grandson's son is ear grandson. That is: son, grandson, great-grandson, great-great-grandson, future grandson, Kun grandson, successive grandson, cloud grandson, ear grandson. The book states: the ear grandson refers to a descendant so far removed that one only knows of them by hearsay.Direct Lineage Relationship\Common Title\Addressed in Person\Self-Designation Biological Father\Father\Dad, Papa, Pa, Pops\Son, Daughter Biological Mother\Mother\Mom, Mama, Mother\Son, Daughter Stepfather\Stepfather\Later Dad\Uncle, Dad\Son, Daughter Stepmother\Stepmother\Later Mother\Stepmom, Mother\Son, Daughter Father's Father / Father's Mother\Grandfather, Grandmother\Grandpa, Grandma\Grandson, Granddaughter Father's Grandfather / Father's Grandmother\Great-Grandfather, Great-Grandmother\Great Grandpa, Great Grandpa, Great Grandma, Great Grandma\Great-Grandson, Great-Granddaughter Siblings\Brothers and Sisters\Older: brother, sister; Younger generally addressed by name\Younger brother, older brother, younger sister, older sister Husband\Husband\Old man (someone's father by daughter's name), also sometimes directly by name\Wife Wife\Wife\Lady\Old woman (read as Ning) (someone's mother by daughter's name), also sometimes directly by name\Husband Husband's Father\Father-in-law\Grandfather In old times addressed as grandpa or grandma via children; now addressed via husband as dad, papa, mom, mother-in-law\Daughter-in-law Husband's Mother\Mother-in-law\Grandmother Lateral Blood Relationship\Common Title\Addressed in Person\Self-Designation Father's Elder Brother / Father's Younger Brother\Elder Uncle, Younger Uncle\Elder Uncle, Big Dad, Uncle, Second Dad, Third Dad, Little Uncle, Uncle\Nephew, Niece Elder Uncle's Wife / Younger Uncle's Wife\Aunt\Big Aunt, Aunties, Eldest Aunt, Big Aunt, Aunt, Aunt, now also called Second Aunt, Third Aunt, etc.\Nephew, Niece Elder Uncle's Children / Younger Uncle's Children\Cousins\Addressed like one's own siblings, prefixed with 'Cousin' when introducing\Younger brother, older brother, younger sister, older sister Father's Sister / Father's Sister\Aunt\Aunt, Big Aunt, Auntie, Uncle, Aunt, now called Big Aunt, Second Aunt, Uncle, etc.\Nephew, Niece Brother's Wife / Younger Brother's Wife\Sister-in-law\Sister-in-law, Elder Sister-in-law, Second Sister-in-law, etc., now sometimes addressed directly by name\Previously called Uncles, now called younger brother or older brother Husband's Brothers\Elder and Younger Uncle\Previously through children called Big Uncle, Uncle; now addressed via husband as brother, or directly by name\Younger Sister-in-law, Sister-in-law Father-in-law or Mother-in-law of Son-in-law / Daughter-in-law\Parents-in-law\Parents-in-law called older brother or sister-in-law through children; now called son-in-law or daughter-in-law's father or mother (the respective parents)\Younger Sister-in-law, Sister-in-law, Younger Sister, Older Sister Husband of Aunt\Uncle by Marriage\Uncle-in-law, previously called Big Dad, Second Dad, Big Uncle, now called Big Papa, Second Papa\Nephew, Niece Aunt's Children\Aunt's Cousins\Addressed as elder brother, younger brother, elder sister, younger sister, or prefixed as 'Cousin'\Cousin (younger), Elder Brother, Younger sister, older sister Maternal lineage Blood relationship \ Titles \ Common names \ Face-to-face addresses \ Self-designation Mother's parents \ Maternal grandfather and grandmother Grandparents Grandfather, Grandmother \ Grandchildren and granddaughters Mother's brothers and their spouses \Uncle and aunt \ Mother uncle and aunt \ Uncle, uncle, aunt Aunt Nowadays called uncle, aunt mother \ Nephew, niece Niece Children of maternal uncle \ Cousin cousin \ Addressed by brother, younger brother, sister, sister or prefix with the character "Biao" \ Cousin, brother, sister, younger sister Sister Sister and their spouse \ Uncle and aunt \ Uncle aunt \Old titles Da Di, Da Ma, Uncle, aunt, now called 'big dad', 'big mother', aunt \ nephew, niece's child, \ maternal cousin, and sister, addressed as brother, brother, sister, or with the prefix 'biao' added.
