Prologue.

Lao Tzu from the Jin Dynasty, ruled by the descendants of Shun, who first created the rite, was born in Gokin-ri of the Cho dynasty. In 534 B.C., the Jin Dynasty fell to the Cho Dynasty. Laozi was said to be a contemporary of Confucius during the 6th or 5th century BCE. In 501 B.C., a 51-year-old Confucius in the Noh Dynasty, set out on a journey to find Lao-tzu, an old man with full hair, to learn the etiquette of the Jin Dynasty. According to the records of ‘the Zhuangzi’, they met in middle-upper stream of Huisu, not far from the Sang of the old Jin dynasty. Confucius first encountered Lao-tzu\'s natural and self-free philosophy. He turned away after confirming that it is distinctly different from his politics of humanity, which he tried to heal the world with courtesy and benevolence. Lao Tzu turned his back on the world in despair in the age of the brute. He felt the ephemerality of the human world. At Hamgokgwan, he left 5,000 characters of \'The Tao Te Ching\' to Yoon-hee to leave. It is the cradle of all philosophy and thought.
