Taboo: taboo. In a feudal society, no, in a civilized and etiquette society, we pay attention to respecting our elders and ancestors. Descendants are not allowed to call their ancestors by their names. If you want to address your ancestors by their names in spoken language, you should first say "taboo" and then the name. In written records, such as "In inscriptions and genealogy books, when the records are arranged vertically, the word taboo is written half a character off to show the respect of future generations for the ancestors." When women are called sisters, they are also called rows, that is, brothers are numbered in row one, row two, etc. to express the order.
