In today's parlance, "I" and "I" are synonymous. In fact, there are still differences between them. In the Song Dynasty, there was a copy of the "Four Books", which said that "I" refers to myself, such as "I know what I know"; to others, it is "I", such as "I have a humble man who asked me." The difference here is subtle. However, this is not a very important thing, because "I" is rarely used now. This kind of subtle difference is enough to know as a little knowledge, and it is harmless not to know.

When writing letters, acquaintances often do not sign names, and at the end they write "not well-known", revealing a kind of intimacy. However, in the Tang and Song Dynasties, the word "not possessed" should not be used indiscriminately. It can only be said by elders to juniors, and superiors to inferiors. What if it was the other way around? When the inferior is opposed to the venerable, one must use the phrase "well-known and unprepared." Among peers and friends, only "well-known and unknown" can be written. Wei Tai of Song Dynasty talked about this difference in "Dongxuan Records". Wei Tai said that literally, there is no difference between the three writing methods, and it is not known who decided on them. There are also two titles that are often used in costume dramas, namely "Master" and "Adult". To elaborate, the title "adult" was unpopular before the Ming Dynasty, because the officialdom of the Ming Dynasty called "Master", but there were many differences. Officials above the level of the Ministry of Foreign Affairs and Taoism are called "Masters", while relatively low-level officials are called "Masters". As for squires, landlords, etc., they cannot be called "Master", only "Father". What's interesting is that if the father is already "Master", then no matter how old the son is, others can't call him "Master", only "Master".

The title "adult" was not accepted for a time in the early Qing Dynasty. In the Qing Dynasty's "Liu Nan Essays", there was a county magistrate named Li Yusen. When he saw the inspection officials from the imperial court, he called the other party "adult", and the other party was angry. Li Yusen explained, "How beautiful is the title of your lord. If you don't use it to address you, it's a cheap word." The other person's expression changed immediately.

Later, "adults" gradually became popular. In short, Master Zhang, Master Li and so on started to scream. However, it should be noted that "adult" is still a title among officials. Officials (official clerks hired by the government) and ordinary people still have to call officials "Master" and "Big Master".

In ancient times, even among ordinary people, there were some titles used to distinguish people. For example, young men are divided into two categories. Literary and artistic young men who have studied well and have backgrounds at home will be called "shows", such as Zhang Sanxiu and Li Wuxiu. The word "show" once became a common word in boys' names. And ordinary young men are called "Lang", Zhang Sanlang and Li Wulang. Slowly, the title "show" also spread to women. In Jian'an of the Northern Song Dynasty, there was a woman surnamed Xu who wrote the book "Girls' Collection". Since then, girls who can recite poetry and have culture are called "girls". Later, women basically stole the word "show", and men don't use it much.

There are two commonly used titles: teacher and classmate. In fact, these two words are all only in the Ming Dynasty. Before the Ming Dynasty, people called teachers "Sir", but when Yan Song came to power, the situation changed. The flattering people called Yan Song "Teacher", and the more nauseous, "Old Master", the implication was Teacher Yan Straight to Confucius.

As for "classmates", they appeared in the late Ming Dynasty. I used to go to school, a teacher taught a class called the same class, the same class of candidates called the same year, no classmates. Huang Zongxi, an elite at that time, wrote in the annotation of a poem: "Students are called Yu Yu and Shen Meisheng (Shen Shoumin) and Lu Wenhu (Lu Fu)." opened.

Different eras have different names. Literary and artistic works are not history books. If you use them incorrectly, you may not know it. Anyway, you don’t take them seriously. But if you use it correctly, it shows how rigorous and serious you are.
