Huangdi Neijing, a monograph of traditional Chinese medicine, records the realm of "real people". The first article of Huangdi Neijing, On Ancient Naivety, said: "I heard that there were real people in ancient times, who helped heaven and earth, grasped yin and yang, breathed essence and stayed awake independently, so they could live a long life in heaven and earth without end." 」
The Taoist School's Zhuangzi also describes real people, such as the great master: "The real people in ancient times slept without dreams, felt carefree, ate without wanting, and breathed deeply." "The World" said: "Guanyin and Laozi are both great men in ancient times. 」
The founder of Taoism is often called a real person. Taoism holds Zhuangzi as "the truth in the south" and Liezi as "the truth in Xu Chong". Zhong Liquan, a famous immortal, was called "Zhengyang Zhenren", Lv Dongbin called "Chunyang Zhenren", Liu Haichan called "Yang Guang Zhenren", and Wang Zhongyang, Ma Danyang, Qiu Changchun and Zhang Boduan, the founders of Quanzhen Road, were all honored as "Zhenren". In the Ming Dynasty, Zhang Zhengyi Shi Tian changed his name to "Zhengyi School teaches everyone".
There are also real people's sayings in the Buddhist "Infinite Life Sutra".
Qin Shihuang also called himself a "real person". The Historical Records of the First Qin Emperor contains: Lu Sheng said that the first emperor said: "Those who seek miraculous medicines and immortals often encounter those who harm things. In the square, when people are in power, they will do good things to exorcise evil spirits, and real people will come. Master alive, ministers know, is harmful to god. Real people, who are not immersed in water or fire, have a long relationship with heaven and earth. Today, the rule of the world has not calmed down. The palace where I used to live was unknown, and then the medicine for immortality was almost available. " So the first emperor said, "I admire real people and call myself a real person, not me."
In Japan, Emperor Tianwu decided on the eight-color surname and awarded the real person as the first class to future generations.
