According to the author's preface, this book is written to answer the question of whether his disciple Teng Sheng is immortal: "There are hundreds of reporters in Dr. Qin Ruancang's office and more than 70 reporters in Liu Xiang's office. However, the immortal is secluded and different from the world, and there are still thousands of people who have heard of it. " ..... Today, copying ancient immortals can be found in the immortal classics, eating parties and hundreds of books. As the former teacher said, Confucian scholars thought it was ten volumes, in order to spread knowledge to people who know far. "
