In 520 BC, the Eastern Zhou Dynasty was in danger. The royal families were fighting among themselves, fighting each other, the princes were fighting, and everyone was in ruins. Laozi, the keeper of the dynasty's treasure room and the scribe under the pillars, was wronged and in danger. He was forced to go into seclusion and was hunted down. Yin Xixi, a senior official in the state of Chu, was upright and could not bear the humiliation. He resigned and was appointed as the magistrate of Hangu Pass. I avoided trouble and was lured by an undercover agent of the Qin State to ride an ox westward. I landed at Hangu Pass and was entertained by Yin Xi. The two knew each other late. Both were framed by traitors and had no way to serve the country. Laozi angrily wrote the "Tao Te Ching". Yin Xi was deeply moved and became a disciple. He decided to hang up his crown and follow his teacher to the west, and narrowly escaped from Hangu Pass. The Qin State recruits talented people, designs and supports them, and entertains them as much as they want. Lao Tzu climbed the sacred cattle plowing furrows in Huashan Mountain and wrote riddles. He lived in a tower and watched the tower to discuss the past and the present. He was close to the Weishui River and admired Jiang Taigong for fishing to discuss the rise and fall. He went to Qishan Mountain to admire King Wen of Zhou Dynasty and accepted talents. The King of Qin has evil plans and wants to take back control; King Jing's killers are also pressing harder, so Yin Xi has no choice but to accompany me at night to continue his escape to the west. After an arduous journey and a narrow escape from death, he went west to Dunhuang, where he paid homage to the rock paintings of his ancestors, preached scriptures, and resolved ethnic conflicts. In 471 BC, Lao Tzu met his son in Didao after traveling thousands of miles. Regardless of his old age and physical decline, he devoted himself to serving the people.
