Maintaining family lineages was a vital part of organizing the nation, serving as both a historical archive and a military registry. The official records summarized the total count of warriors drawn directly from these family genealogies. This process of enrollment captured the final headcount of everyone registered, while also relying on the physical genealogical books carefully kept in the families' possession.

The census was highly structured, organized strictly by the natural progression of generations and arranged according to the heads of each ancestral household. Alongside these established family leaders, a vast force of capable warriors was assembled and counted. The final tally of all the fighters and military men standing ready under their command reached exactly twenty thousand, two hundred men.
