Chinese medicine is a science that studies the physiological functions, pathological changes and disease prevention and treatment of human beings. On the one hand, it has natural properties as an organism, and on the other hand, it has social properties as a society. Therefore, Chinese medicine should be between natural science and social science, and it can belong to the humanities, and it is not too much to be called “human science”. “Culture” is the expression and record of national worldview, and any form of record and creation are all components of national culture. Chinese medicine is an expression of the worldview and methodology of the Chinese nation that studies the laws of mutual interaction between human beings and the natural world. Chinese medicine was conceived in the Spring and Autumn Period and the Qin and Han Dynasties, when Chinese academic culture flourished, and has gradually developed and matured to the present day, unique to the world. Therefore, Chinese medicine is a treasure rooted in the excellent traditional culture of the Chinese nation. Chinese medicine is not only a product of Chinese traditional culture, but also an interpretation of Chinese traditional culture from the aspect of medicine, which is an important part of Chinese culture. Yan Yongbin, Department of Pediatrics, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine, recognized early that there are some time rhythms in human physiology, pathology and disease regression, which are called biological clocks in contemporary times. The concept of annual biological clock, monthly biological clock, weekly biological clock and daily biological clock has been reflected in “Nei Jing”. The “seven-day self-healing” in the “Treatise on Typhoid” is a development of the understanding of the weekly biological clock of the Neijing. In the Nei Jing, there is a discussion of the seven days as the key point for the return of disease, for example, Su Wen – Treatise on Fever said: “Nowadays, all fever patients are like typhoid. The death of a person with fever is either healing or death, and the death of the person is within six or seven days. The “seven-day self-healing” in the Treatise on Typhoid Fever is the result of a combination of clinical experience, culture and science, and the seven-day healing, which elevates clinical experience to theory, is related to the “seven-day coming back” in the I Ching. In different historical periods of China’s ancient culture, sometimes “seven” was used as the auspiciousness, and sometimes “seven” was still spoken, forming a “seven culture” with different characteristics. In the Han and Wei dynasties, “seven” was used as an auspicious sign, and both the “Oriental Shuo Book of Divination” and the “Book of the Ages” took seven days as the “human day”, saying that heaven and earth were first opened, one day for chickens, two days for dogs, three days for pigs, four days for Sheep, five days of cattle, six days of horses, seven days of people, eight days of grain, the seventh day of the first month of the Lunar New Year as the “People’s Day Festival”. The poet Xue Daoheng of the Northern and Southern Dynasties wrote a poem called “The Day of the Man”, which has been passed down through the ages, saying: “It has only been seven days since spring, but a year since I left home. After people return to the geese, they are thinking of the flowers.” In ancient times, there was also the fitness activity of “seven days to ascend to the heights”. The Hanshu – Ruling Calendar, with seven as the beginning of the three talents four times to explain the importance of the seven, said: “seven, the beginning of the four times of heaven, earth and people.” Late Qing Dynasty scripture master Yu Yue in the “style of general interpretation of the narrative,” said, “the ancient words, less then said one, more then said nine, half then said five, the small half said three, the large half said seven.” Han and Wei scholars modest, said to be able to understand most of the half, so the book name chapter name more with seven, such as the Mie multi “seven hair”, Cui Yuan “seven Li”, Cao Zhi “seven Qi”, Wang Chon “seven interpretation”, Huan Lin “seven said” and so on. The “Treatise on Typhoid” was written in the era when the word “seven” was still used, and the condition on the day of self-healing coincided with the seven days of coming back, so “seven days of self-healing” was written into the article, which is the embodiment of cultural sentiment.
