What is the preface of Huangdi Neijing?

The earliest preface of Huangdi Neijing was written by Bing Wang in Tang Dynasty. The full text is as follows:

Extensive Annotations —— Preface to Huangdi Neijing Su Wen

Without the three saints, it is impossible for the husband to get rid of the shackles, get rid of the predicament, thoroughly guide the spirit, save Li Yuan's life, win the disadvantage and gain security. Kong Anguo prefaced The Book of History by saying: The books of Fuxi, Shennong and Huangdi are called the three graves, which is also called the avenue of words. Ban Shu? Yi Wenzhi: Eighteen volumes of Huangdi Neijing. "Su Wen" is his classic nine volumes, and it is also the nine volumes numbered "Lingshu". Although he has been handed down from generation to generation for many years, this teaching still exists, fearing that he is not that person, but sometimes he is hidden. Therefore, the seventh1volume, which was hidden by the teacher's house, is sought after by people today, but it is only eight volumes. However, its simple prose is rich in meaning, philosophical and rational, and interesting. It is divided into images of heaven and earth, the order of yin and yang, the reasons for changes, the signs of death and life, and the similarities between the two places. Don't make an appointment, keep a secret, check what you said and what you did. Honesty can be described as the Sect of Tao and the beginning of life. If the secret is sent quickly, the wonderful knowledge is mysterious. Although success is based on knowledge, the standard is also based on training. No trip can be made, and no one can get out. However, if you deliberately study the essence, explore the hidden, or know the real meaning, you will have no eyes, so you will move successfully, you will be praised by ghosts and gods, and you will be a great person. Zhou has Qin Gong, Wei has Zhang Gong and Hua Gong, all of which have magical methods. Salt is used every day. It helps to steam people. China's leaves are honored. Sound and reality are complementary. This is also a festival in heaven.

When the ice is weak, I yearn for Taoism, so it is good to keep in good health. Fortunately, when it meets the Sutra, it is a tortoise mirror. However, the book of the world is a mistake, with overlapping articles and irrelevance. The meaning of words is separated, which is difficult to implement and cover meetings. The years are both submerged and attacked. Or reissued, not twice; Or the two theories are attached together, both of which are one eye; Or if the question and answer is not over, don't create a topic; Or take off the simplified book, but the cloud valve. Emphasis is placed on the combination of meridians and crown needles, the combination of prescriptions and cough, the division of excess and deficiency and disobedience, the combination of meridians and discussion, the combination of skin and acupuncture, and so on. It will be promoted to Daiyue again. If you don't transport Wei and help Sang, there will be no boat. He is a diligent and knowledgeable person, and he has a real person. Twelve years later, Zhen Fang has been thinking about the reasons, seeking gains and losses, and deeply regrets it. At that time, Yu Xiansheng lent Guo Zi to the church and got a secret copy of his former teacher Zhang Gong. The words are clear and clear, and the meaning lies in Zhou Zhou. Once explained in detail, doubts were eliminated. I'm afraid I'll break up at the end of the semester and I'll never be a teacher again. Therefore, I will write notes and use them to spread immortality. It is also an old volume set, which consists of 81 articles and 24 volumes. I hope to study the ending and the beginning, find out the classics, develop children's learning and publicize the truth. Among them, those simple and disjointed, whose meanings are not connected, search all the classics and migrate to make up for it. If the title is missing, please measure its interest and add words to show its meaning. When discussing annexation, the meaning is irrelevant, the name is missing, and the title is the first to distinguish things from categories. Excuse me, your majesty and your subjects, those who have lost their virtue will be honored. Those wrong and concise, overlapping, explain their meanings in detail, and cut complexity in order to preserve their essence. If it is difficult to explain these secrets in detail, don't write "Zhu Xuan" and use Chen Qi's way. All the words added are written by Zhu, which makes the present and the present different, and the words are not mixed. It's like hanging high in a row, keeping the order of honor, keeping the deep spring clean and keeping the scales salty. There is no time to waste your life. Hopefully, your life will be extended in summer, so that workers and disciples will not make mistakes. Scholars can only be wise, Taoist scriptures are popular, and the emblem sounds very tired. Thousands of years later, you will know that the kindness of the Great Sage is endless.
