What is the surname of Confucius?

Kong Qiu (5565438 BC+September 28th (August 27th of the lunar calendar) ~ April 479 BC 1 1 February 11th of the lunar calendar) was a Zhongni, a native of Lu in the Spring and Autumn Period, and a Han nationality. Confucius was the greatest educator and thinker in ancient China, the founder of Confucianism and the most famous cultural celebrity in the world. Confucius was born in Changping Township (now Luyuan Village, southeast of Qufu City, Shandong Province) on September 28th, 55/Kloc-0 BC (August 27th in the summer calendar). On April 1 1 day in 479 BC (February 11th of the lunar calendar), Confucius died at the age of 73 and was buried in Surabaya in the north of Qufu where Kong Lin is now located. Confucius' thoughts on words and deeds are mainly contained in Prose Collection, Analects of Confucius and Four Books. According to historical records, Confucius' family, Confucius' ancestors were descendants of Shang Dynasty. After the destruction of Shang Dynasty in Zhou Dynasty, Zhou Wuwang was made an ordinary brother, and Wei Zi was made a loyal minister in Song Dynasty. After Wei died, his younger brother Wei Zhong succeeded to the throne. Wei Zhong was the ancestor of Confucius. After Jia, the sixth ancestor of Confucius, his father, descendants began to take Kong as their surname. His great-grandfather Kong fled from the Song Dynasty to Shandong to escape the civil strife in the Song Dynasty. Confucius' father was a famous warrior in Lu. Shu married Shi first and gave birth to nine daughters without sons. My concubine gave birth to a son named Meng Pi, but he had foot disease. Under the circumstances at that time, neither a woman nor a disabled son should inherit. In his later years, Shu Liangyou and the young woman Yan Zhizai gave birth to Confucius. Because Confucius' mother went to Niqiu Mountain to pray, and then she became pregnant with Confucius, and because Confucius was born with a depression in the middle of his head, like Niqiu Mountain; Therefore, it was named Qiu (Zhong is the second son, Shu's eldest son is Meng Pi, and Meng is the eldest son). When Confucius was three, Shu died of illness. After that, Confucius' family was quite poor. For various reasons, Confucius didn't make much achievements in politics, but in the three months of governing Lu, it shows that Confucius is worthy of the title of outstanding politician. Political dissatisfaction enabled Confucius to devote a large part of his energy to education. Confucius once worked as a scout in Lu, then traveled around the world with his disciples and finally returned to Lu to concentrate on teaching. Confucius broke the monopoly of education and created a precedent for private schools. There are as many as 3,000 disciples of Confucius, including 72 sages, many of whom are the pillars of senior officials in various countries. Confucius had a far-reaching influence on later generations. When he was alive, he was known as a "heavenly saint", "many heavenly eyes" and "immortal sage". He was one of the most learned scholars in the society at that time, and was called the most holy (saint among saints) by later generations, the teacher of all ages. He edited poetry books, defined rites and music, prefaced Zhouyi and wrote Chunqiu. Confucius' thoughts and theories have far-reaching influence on later generations. The Analects of Confucius is a classic work of Confucianism, compiled by Confucius' disciples and disciples. It is a book that records the words and deeds of Confucius and his disciples. 1988, 75 nobel prize winners issued a joint declaration in Paris, calling on the world that "if human beings want to survive in the 2 1 century, they must learn the wisdom of Confucius two thousand years ago." This shows the great thoughts of Confucius.
