The Miao names of both men and women are all single-syllable names. Female names include "bangx", "eb", "nil", etc.; male names include "box". ), Jin (jinb), Weng (ongd)" and so on. When the elders call the younger ones, they can call them by their single-syllable names; if they refer to their Miao names, they must be connected with their fathers to become the Miao names of the son (daughter) and father. For example: the son's single-sound seedling is named "box", and the father's single-sound seedling is named "ongd", then the reference name of "box" should be "box" ongd)"; if it is generally symmetrical, the honorific word "dial (brother)" should be added before its monosyllabic name to become "dial box". In the southeastern part of Guizhou, in addition to the son (daughter) and father name system, there are also some areas that adopt the three-generation name system of son, father and ancestor. For example, the son's name is "Bao (box)" and the father's name is "Weng (Weng)". ongd)" the grandfather's name is "lix", then the Miao name of the son's name "Bao" is "box ongd lix". This continuous naming system of three generations of son, father and ancestor is not widely used in areas. If we use twenty-five years as a generation and trace back the family genealogy of the son (daughter) and father, we can know the historical era of a certain family that continues to this day.
