When a woman is 15 years old and gets married, a hairpin ceremony is held to pick her name. Special attention should be paid to the fact that before respecting one’s elders, all self-proclaimed names must be used, not words. When interacting with ordinary peers and juniors, the other party must call me by my first name. If I call me by my first name directly, it will be offensive. "Calling him by his first name" and "calling him by his surname" have never been complimentary terms. This is where they come from. Although the ancients had various ways of naming and choosing characters, names and characters generally have a certain connection in meaning, which can be summarized as follows: those with the same meaning: that is, the characters and names have the same meaning and are in a parallel relationship, so they are also called " Parallel". Such as: Qu Ping, whose courtesy name is Yuan. Guangping said the original. Yan Hui, courtesy name Ziyuan. Yuan, backwater. Zhuge Liang, also known as Kongming, has very similar meanings to "Liang" and "Ming". Du Fu, whose courtesy name is Zimei, the interpretation of "Fu" is "the title of a beautiful man in ancient times".
