What is the origin of the word "he"?

Sima Qian's "Historical Records of Confucius" records: "Ge had a wild relationship with Yan's daughter, gave birth to Confucius, and prayed for Confucius in the mud hill. Duke Xiang of Lu was twenty-two years old and Confucius was born. First born ■ Top, hence the name Qiu Yun. As can be seen from the last paragraph, Confucius' famous mountain was named not because his uncle Ge Liang prayed in the mud mound (mountain name), but because of the head feature of Confucius when he was born: "top". "■" means adding a word "Yu" next to the word "earth" to mean "concave". ■ The top is a depression on the top of the head. It is said that Confucius' head is low in the middle and high around. "Mountain" means heaped-up mountains. Confucius was born with a rough head, so he was named Qiu. In Confucius, "loyalty" is the ranking of ancient brothers, and the second line is bell. Confucius was the second child in his family, and he was named Zhong Ni because his father went to the mud mound to pray. There can be various connections between ancient names and characters. From the example of Confucius, we can see that the connection between some ancient names is difficult for us to see today.
