Writing source:
The ancient writing of "domain", which is a hieroglyph. The curve in the middle is like the trace (or ridge) left by plowing, and the left and right semicircles represent the tools for plowing (also like the shape of the hoof print of a cow when plowing). Together, these two parts form a "field" that represents the meaning of the field.
In Shuo Wen Jie Zi, the orthographic method of Xiao Zhuan adds the radical "Tian" with ideographic meaning, which becomes a pictophonetic character with left form and right sound. After the official change, the phonetic symbol was changed to "Shou". But the word * * * has nineteen paintings, which is troublesome to write, so it was later simplified as "domain".
The original meaning of "domain" is cultivated land. Later, it was extended to "the division of crop planting", such as the "melon and taro area" mentioned by Zuo Si in Shu Du Fu. From "zoning" to "species" and so on. Sometimes, the word "domain" also means "trouble". For example, in Xunzi's "Encouraging Learning", there are some words: "Plants are born in the field, animals are crowded, and everything belongs to its kind." Here, "domain life" means "life", which means that all the same kind live together.
As for "domain officials", they don't refer to the same kind of officials, but to those who have been the same kind of officials throughout the ages, especially those who have been passed down from generation to generation. For example, "Historical Records of the Turtle": "Father and son are domain officials, passed down from generation to generation."
