When were the ancients called ideographs?

"Book of Rites Tan Gong" holds that people need to be respected by society in the process of growing up, and it is disrespectful for peers to call them by their first names. Therefore, they need to adopt an ideograph for themselves to use when interacting with others in society to show mutual respect. Therefore, when the ancients came of age, their names were only used by their elders and themselves, claiming that names meant humility, while epigrams were used by people in society.

Ideographic characters, also known as Chinese characters, are aliases related to the meaning of their original names, which are traditionally given to themselves by Chinese character cultural circles.
