Why in ancient times were some men named with the character for uncle and women with the character for mother?

In ancient times, "uncle" was used to indicate the order of seniority among brothers. Uncle was the eldest brother, Zhong was the second, uncle was the third, and Ji was the least. In ancient times, when people named their babies, they did not go through various books or search for various materials on the Internet like many parents today, just to choose a good name for their children. In ancient times, for many low-income families, the most important thing was to be able to support themselves, so they didn't care much about the baby's name, and they often picked one randomly based on ranking. In ancient times, "mother" specifically referred to women, generally young women. For example: Seeing my mother happy and beautiful, I would like to get a golden orchid. —— "Midnight Song" by Ancient Yuefu. There are also: Sun Erniang and Hu Sanniang in "Water Margin".

The uncle is the ancestor, and the mother is the mother. People call their father's eldest brother and sister-in-law uncle and aunt (regional dialect: old man and aunt). Similarly, boys who are older than their father are also called uncle. Dad's younger brother and sister-in-law are called cousins ??and aunts (third master, third mother). Mom’s sister and brother-in-law (eldest aunt and uncle), mother’s biological sister and brother-in-law (third aunt and uncle). There is a famous saying here: "Aunt and aunt are like mothers." The ancient people's "Bo Zhong Shu Ji" refers to the eldest brother, the second eldest brother, the third eldest brother, and the fourth eldest brother. People often say that there is no distinction between Zhong Bo, which means that they are evenly matched, and they are in the middle between the eldest brother and the second eldest brother.

"Uncle" was a ranking in ancient times. Bo (Meng), Zhong, Shu, Ji, is the order in which brothers and sisters are ranked. Boyikao, "Bo" indicates that he is the son of Xibohou. Kong Zhongni, "Zhong" indicates that Confucius is the second child of the Confucius family. During the "Cultural Revolution", "Confucius" (ie Mencius) was criticized. He is indeed the second child and has an older brother named Meng Pi. Liu Wenshu, "Uncle" means that he ranks third among the brothers in the family. Zhuge Jida, "Ji" means the fourth brother, he is Sima Yi's fourth brother. "Mother" generally refers to a young woman in ancient Chinese literature, often referring to a beautiful girl. In ancient times, when naming baby girls, they often used "mother" in the name, which not only indicates the gender of the fetus, but also is a folk custom.

"Li Siniang" shows that she is the fourth daughter of the Zhao family. "Du Shiniang" ranked tenth. Ancient people also called them "Qiuniang" and "Xie Niang". "Qiuniang" has two meanings. One refers to beautiful women, such as "Qu Ba once taught talented people how to dress well, and she was always jealous of Qiuniang." Ertong refers to a smart and talented woman. Du Qiuniang in the Tang Dynasty also read the poem "Flowers in full bloom are worth breaking, but don't wait until there are no flowers to break branches." "Xie Niang" refers to a strange woman, also known as a beloved woman. For example, "I remember that year in front of the flowers, in the middle of the night, when I first met Xie Niang."
