How did the ancients address each other's names and words?

In ancient times, due to special attention to etiquette, names and characters were very particular. In interpersonal communication, first names are generally used as polite terms, courtesy names, respectful names and long names. Peers only call each other by their first names when they know each other well. In most cases, it is considered impolite to mention each other or call them by their first names. It is considered polite to compliment each other among peers. When writing letters or calling superiors and subordinates, you can call them by their first names, but you must never call them by their first names, especially the names of the monarch or parents and elders, otherwise it will be "disrespectful." In ancient times, names and words were called together to show respect. There are two situations that deserve our attention: the first situation is that in the pre-Qin period, when a name and a word are linked together, the word should follow the name. Such as: Confucius, the ancestor of Confucius in the Song Dynasty, with the correct word "Kong Fu"; Jia is a name; The surname is "Gongsun". Uncle (hé), the father of Confucius, "Ge" is a name; Liang Shu is a word; Last name is Kong.
