Ancient to be named with a name, character, number, why is there such a rule?

First of all, the ancients attached special importance to the name, so this is the need to address. In ancient times, not everyone had a surname, only the nobles were eligible. Commoners were like grass, with only common names. Calling people by their names was seen as rude in ancient times, hence the so-called avoidance. For respected people, elders, especially can not call their names. Dream of the Red Chamber also mentioned that Daiyu avoided writing the word Min because her mother was Jia Min. So the ancients needed some titles to be called by, is one of the functions of the epithet.

Secondly, the ancient people's surnames, clans, and first names were separate, and some dynasties paid extra attention to them. In ancient times, a big surname below also divided into many clans, and different dynasties for the family name is not quite the same, like the Three Kingdoms period of Gongsun, Zhuge, Sima and so on this kind of family name. Although there are a lot of sayings for the surname of Guan, but it is all a distinction of people's identity, and sometimes it can also show the status of people of different ranks.

Another important reason is because the characters, like names, are given by parents. It contains the parents' blessings and hopes for their children. There are many things to consider when choosing a character as there are when choosing a name. The five elements, ancestry, lineage, appearance, and physical condition are all taken into consideration. See the first paragraph of Qu Yuan's Li Sao, which explains the origin of his name. Epithets and names are often complementary, as in Qu Yuan's name Ping Zi Yuan, both meaning flat and broad.

But with the changes in society, there have been many changes in today's social habits, but the way a person is addressed is still something that people need to deliberate on. Whether or not you address people appropriately often determines how the first impression is made. Especially in China, how many people would call their elders or superiors by their first names? That's why we still need to be polite when dealing with name calling, because the way you address a person often carries a positive or negative connotation.
