Laozi, whose real name is Li Minger, whose name is Bo Yang or Bo Yang, was born in the late Spring and Autumn Period. His date of birth and death is unknown, and his native place is also controversial. According to historical records, Laozi was born in Chu or Chen.

China was an ancient thinker, philosopher, writer, historian, founder and main representative of Taoist school, and was also called "Lao Zi and Zhuang Zi" with Zhuangzi. Later, he was revered as the ancestor by Taoism and called "the old gentleman on the throne". In the Tang Dynasty, he was regarded as the ancestor of Li. It is listed as a world cultural celebrity and one of the world's top 100 historical celebrities.

Laozi 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, and Lao Tzu wanted to abandon his official position and retire, so he rode a green cow westward. When I arrived at Lingbao Hangu Pass, I was invited by Yin, the Commissioner of Customs, to write Tao Te Ching.
