How are the generations of relatives divided?

In China, the traditional Han concept of seniority has existed for a long time, centered on itself, there are four generations of elders, and four generations of juniors, forming the "nine clans" of blood relations of "great-grandfather, great-grandfather, ancestor, father, myself, son, grandson, great-grandson, great-grandson, and great-grandson", which is the nine levels of kinship. These are the nine levels. If the collateral blood relations and in-law relations are linked, a huge kinship system is formed.

Only some of them are selected here to show their hierarchical relationships.

The first level: grandfather, grandmother, maternal grandfather, maternal grandmother (the second eldest)

The second level: father, mother, uncle, aunt, uncle, aunt, aunt, aunt, aunt, uncle, aunt-in-law, father-in-law, mother-in-law (the first eldest)

The third level: (per se) older brother, sister-in-law, sister, brother-in-law, sister, brother-in-law, cousin, cousin-in-law , brother-in-law, sister-in-law, brother-in-law (same generation)

Fourth level: sons, daughters, nieces, nephews, nephews, nephews-in-law (later generation)

Fifth level: grandchildren, grandchildren, grandsons, grandchildren, nephews, nieces, grandson in law, grandson out of wedlock (later generation)

The kinship designations are based on the generation, not on the age limit, the older brother is a few years older than the younger brother, and the older brother's child is in turn a few years older than the brother's child a few years older, a few generations later, the descendants of the big door compared to the descendants of the small door, the same generation may be a few dozen years older, and does not affect the relationship between generations, there are often long bearded grandchildren or grandparents in arms. Therefore, the Han Chinese often "big door to the younger generation" said.
