Duke Zhou and Li are both figures in the ancient history of China, and they are important figures in the Zhou Dynasty and the Spring and Autumn Period. Duke Zhou refers to Zhou Gongdan, one of the founders of the Zhou Dynasty, Zhou Wuwang's uncle and regent. Li Gongzi refers to Li Er, the prime minister of the vassal state in the Spring and Autumn Period.
He is a famous politician, strategist and cultural celebrity in China, and has made outstanding contributions to the politics, economy and military affairs of Shandong. He put forward the idea of giving priority to health preservation, supplemented by treatment, which laid the foundation of ancient medical culture in China. In addition, he was a famous essayist and poet in the Lu period, leaving many well-known articles and poems.
Li Gongzi served as a Tibetan shepherd in the Zhou Dynasty and was famous for his erudition. Once, Confucius went to see Zhou and asked him for a gift. At the end of the Spring and Autumn Period, the world was in chaos. Li er wanted to abandon his official position and retire to seclusion, so he rode a green cow west. When I arrived at Hangu Pass, I was invited by Yin, the Commissioner of Customs, to write the Tao Te Ching.
Li Gongzi's achievements
In the thirty-fifth year of the Zhou Dynasty (ten years, 485 BC), Li Er saw the decline of the Zhou Dynasty, so he left his hometown and prepared to travel around Hanguguan. Yin, the great officer guarding Hangu Pass, appreciated Li Er and was very happy to hear that he had come to Hangu Pass. But when he learned that Li Eryao was traveling abroad, he felt it was a pity and tried to keep Li Er. So Yin said to Li Er, "You can go through the customs if you want, but you have to leave a book."
After hearing this, Li Er stayed in Hangu for a few days. A few days later, he gave Yin a book of about 5000 words. It is said that this book was later passed down as Tao Te Ching. Then, Li Er rode away on a big green cow. According to legend, after his retirement, he practiced in Shi Jing (later renamed "Laojunshan").
