Based on Yi Jing, Huang Di Nei Jing and other ancient texts, this paper points out that ancient Chinese calendars are generative calendars. The former include solar calendar, lunar calendar and solar-lunar calendar while the latter include heavenly calendar (heavenly stems), earthly calendar (earthly branches) and calendar of fortune that coordinated heavenly stems and earthly branches. Fu Shi created “Jia Li” and built the foundation of Chinese tradition. Huang Di constituted the heavenly calendar, determined the five elements and the epact, combing ephemeris, Yi Jing, and medicine. The writer points out that astronomic calendars present various movements and cycles of heavenly bodies, and generative calendars show how the growth and retrogression Ying and Yang control the generation and development of the creation. Both astronomic calendars and generative calendars originate from the conception of the unity of heaven, earth and man, which is characteristic of Chinese civilization. The writer also concludes that human body is microcosmos, the miniature of the almanac of the cosmos; life is a cosmic phenomenon that happens and changes according to the cosmic order of generation and development. From the perspective of modern science, the writer offers us a careful examination and creative interpretation of traditional philosophy of life, promotes the conception of human physiological organization as a microcosmos in Huang Di Nei Jing. Besides he also demonstrates how cosmic elements control the dual devolution of the chemical balance of the organism of life. We may say this paper provides the academic world with a new issue about tradition philosophy of life and modern technology of life.
