Why were ancient civilians called Shu Ren? Is there a source?

This problem involves the origin of the word "subaltern", and the relevant explanations are as follows:

I) Detailed description of the source:

Language: "Poetry, Elegance and Lingtai": "Shu Ren attacked it in a few days."

In the era before the Warring States Period, "Shu Ren" was a person with a surname. The word "surname" means "female" and "born" respectively, and the son born to a woman (or in a place) gets the corresponding surname. According to legend, the mother of Huangdi lived near Jishui, so Huangdi's surname was Ji. Where Shun's mother lived, Shun took Yao's surname. At that time, the son did not take his father's surname, such as Huangdi, and gave his descendants 12 different surnames respectively. So at that time, all the people with surnames were princes and nobles, and "people" was "officials" Ordinary people don't know where their ancestors' mothers live, and their ancestors have no power and influence, so they can't be called "ordinary people" They can only be called "Li min" or "common people"

2) Explain the word:

The so-called "subalter" is the Chinese translation of the English word subalter, which also means "subordinate", "lower level" or "bottom level". The dominant or subordinate lower classes in society do not consider the significance of class, caste, age, gender and status; Here, the official and unofficial "elites" and "civilians" are in direct opposition.

First, under the influence of the development and changes in the field of economic production, a social group of ordinary people has objectively formed; Their rapid increase in number and their relationship with pre-existing social groups have maintained their mentality, ideology and goals for a period of time;

Secondly, they actively or passively joined the ruling political class and tried to influence the program of these classes in order to stick to their own demands. These efforts played a decisive role in the process of differentiation, transformation and rebirth.

Thirdly, the birth of a new political party in the ruling group aims to maintain the recognition and control of the lower groups;

Fourth, the class created by the subaltern group itself in order to adhere to the requirements of certain limited status;

Five, those who maintain the autonomy of the new class of ordinary people (in the old system);

Sixth, those who maintain overall autonomy and so on.
