According to records, Confucius’ head was concave, so he was called Kong Qiu. In fact, this is also an honorific title. Although it is a bit incredible, it is true.
The thinking of the ancients was different from ours. They liked to use the characteristics of appearance to describe a person, and they also used this characteristic to give a name, which generally expressed respect.
Confucius was a great thinker and educator in ancient my country. He founded Confucianism and carried it forward. Confucius advocated teaching students in accordance with their aptitude and loving the country and the people. They may not have been adopted by the rulers at the time, but they had a profound impact on future generations. Emperor Wu of the Han Dynasty once promoted Confucianism, and emperors of all dynasties tried to control the people's thoughts. Qin Shihuang burned books to trap Confucians because he did not want the common people to be too open-minded, which led to the trap of many Confucian students at that time.
Laozi once served as Confucius’s teacher, and Confucius learned a lot from him. The ideas of both men were carried forward in later generations. Confucius had many students throughout his life. After Confucius's death, his students compiled some of what he said and formed the Analects of Confucius for later generations. "The Analects of Confucius" is now used as a textbook for primary and secondary school students, influencing the thinking of many young people. Many universities also offer elective courses on the Analects, which shows how much influence Confucianism has on us.
Now there are Confucius schools all over the world, and Confucius’ thoughts are highly praised by people. Perhaps it was precisely because of Confucius' strange mind that he had so many ideas. Another theory is that Confucius's given name was Zhong Ni, and Ni Qiu happened to be the name of a certain mountain, so he was called Kong Qiu. According to this statement, Confucius' head was not concave.
