Abstract: With the development of the times, the ancient view of life has been changing. Some excellent ideas, methods and technologies with great ecological value have been or are being alienated under the impact of scientific and technological progress. The cognition of the value of life has gradually faded, and simple and easy technical methods have been distorted by Western values. In order to make the TCM health preservation knowledge system truly an important part of the Healthy China strategy, it is necessary to correct the cognition of the essence of life, clarify the definition of the connotation and extension of health preservation, set the philosophical premise of health preservation rules, examine the value and significance of the concept of life and death, and solve these basic theoretical elements, so as to give full play to the guiding value of TCM life philosophy to human health.
