Confucius studied hard when he was young. He worshipped the Duke of the ritual and music system in the early Zhou Dynasty and was particularly familiar with ancient etiquette. At that time, he was proficient in the "six arts" that a scholar should learn, namely etiquette, music, archery, driving, writing and calculation. He is conscientious and responsible in his work. At first, I was a clerk in charge of the warehouse, and there was no shortage of materials; Later, when he became a small official in charge of animal husbandry, cattle and sheep multiplied a lot. Before he was 30, his reputation gradually improved.

Someone was willing to worship him as a teacher, so he simply set up a private school to accept students. After the death of Dr. Meng Nuo, Lu told his two sons Meng and Nangong to go to Confucius to learn etiquette. On the recommendation of Uncle Jing of Nangong, Lu also invited Confucius to visit the rites and music of the Zhou Dynasty in Luoyi, the capital of the Zhou Dynasty.

When Confucius was thirty-five years old, Lu was dismissed by three official doctors, namely, He Shu. Confucius went to the state of Qi to see and talk about his political views. Qi Jinggong was very polite to him and wanted to take advantage of him. However, Yan Ying, the prime minister, thought Confucius' thought was unrealistic, so Qi Jinggong didn't use him. Confucius returned to Shandong and still taught his books. More and more students study Confucius.

In 50 1 BC, Lu Dinggong appointed Confucius as the butcher of Zhongdu (now Wenshang County, Shandong Province), and became Sikong (chief engineer in charge of engineering) the following year. He also served as a scout in charge of air conditioning.

This time, Lu told Confucius in Jiagu that he was preparing to form an alliance with Qi. Confucius said, "The State of Qi has repeatedly invaded our territory, and now we are invited to join the League, so we have to guard against it. I hope to bring about Sima. "

Duke Ding of Lu agreed with Confucius and sent two generals and some troops to accompany him to Oracle bones.

At the Oracle bones conference, due to the courtesy of Confucius, Lu won a diplomatic victory. After the meeting, it was decided to return three pieces of land in Wenyang (now southwest of Tai 'an, Shandong Province) occupied by Lu to Lu.

Li Yan, a doctor in the State of Qi, thought that it was not good for the State of Qi for Confucius to stay in Lu as an official, and suggested sending a group of female musicians.

Qi Jinggong agreed, so he selected eighty singers and asked them to meet Lu.

Lu accepted this class of female music, eating, drinking and having fun every day, regardless of state affairs. Confucius tried to persuade him, and he avoided Confucius.

This incident disappointed Confucius. Confucius' students said: "Lu Jun is not doing his business, let's go!" " "

After that, Confucius left Shandong and traveled around the world with a group of students, hoping to find an opportunity to implement his political ideas.

But at that time, big countries were busy with the war for hegemony, small countries were in danger of being annexed, and the whole society was changing. Of course, no one accepted Confucius' proposal to restore the ritual and music system in the early Zhou Dynasty.

He has been to Wei, Cao, Song, Zheng, Chen, Cai and Chu. The monarchs of these countries don't need him.

On one occasion, Confucius sent someone to invite him with King Chen and King Zhao of Chu. The doctors of Chen and Cai, fearing that Confucius' arrival in Chu would be bad for them, sent troops to stop Confucius on the road. Confucius was besieged there, with no food and no food for several days. Later, Chu sent soldiers to relieve him.

Confucius traveled around the world for seven or eight years, but he met many nails and got old. Finally, I returned to Shandong and focused on sorting out ancient cultural classics and educating students.

In his later years, Confucius also compiled several important ancient cultural classics such as The Book of Songs, Shangshu and Chunqiu.

In 479 BC, Confucius died. After his death, his disciples continued to teach his theory, forming a Confucian school, and Confucius became the founder of the Confucian school. Confucius' academic thought has a great influence on later generations. He is recognized as the first great thinker and educator in ancient China.
