The characters and numbers are the ancient people’s habit of naming. In ancient my country, when a man reached the age of 20, he had to perform a crown ceremony and get his first name. "Book of Rites? Tan Gong": "Young name, crown character." This is the meaning of the "crown character". "Historical Records? Biography of Laozi": "The surname is Li, the given name is Er, and the courtesy name is Boyang." Qu Yuan's "Li Sao": "The name Yu is Zhengzexi, and the courtesy name is Lingjun." After choosing the name, in order to show respect, in addition to "Jun" and "Father" are both in front and outside, and they are generally called by names but not by names. "Rituals? Shi Guanli": "When someone is crowned with a given name, he is respected by his name. Before the king and father, he was called by his name, and others are called by his given name."
"Hao" refers to titles other than a person's name and given name. For example, in "The Biography of Mr. Wuliu" by Tao Yuanming, a poet of the Eastern Jin Dynasty: "There are five willow trees beside the house, so I thought it was called Yan." The nickname is also called Yan, such as Li Bai, whose courtesy name is Taibai, and his nickname is Qinglian Jushi; Jiang Kui, whose courtesy name is Yaozhang, and his nickname is Yan. No. Baishi Taoist. Nicknames are sometimes also called nicknames, which are given to oneself as adults. (Some people also ask celebrities or knowledgeable people to pick it up.) The word is used in public places, and it is also the most widely used after adulthood. It is not just the ancients who have names. In modern times, Sun Yat-sen, Mao Zedong, Chiang Kai-shek... including many ordinary people all have names and names. Chiang Kai-shek usually did not address his senior generals by their names, but by their first names to show the identity of his father. (You can often see it in movies) Those characters in "The Romance of the Three Kingdoms" that you have seen are all "zi". Such as Liu Bei (named Xuande) Guan Yunchang (named Yu) Zhang Fei (named Yide) Zhao Yun (named Zilong)...etc.
