The corresponding astronomy implications of yin-yang and five phases of traditional Chinese medicine are investigated based on the modern astronomy,universal biology,and literature research.It is found that the principles of yin-yang in traditional Chinese medicine actually refers to the strengths and the directions of gravitational forces,electromagnetic waves,high energy particle flows of celestial bodies to human.The yin-yang in the human body is a result of selective evolution from protobiont under the influence of yin-yang of celestial bodies in hundreds of millions of years.The revolution of seven luminaries,which includes the Sun,Moon,Mercury,Venus,Mars,Jupiter and Saturn,creates the day and night yin-yang from the self rotation of the Earth,season yin-yang from the revolution of the Earth around the Sun,the yin-yao from the rotation of the Moon around the Earth,and the yin-yao from the rotations of the Mars and the Jupiter.The 10 years cyclic movement of the Mercury displays the states of jiayi,bingding,wuji,gengxin,rengui,which have the allelopathic characteristics of five phases-wood,fire,earth,metal and water,respectively.With the addition of yin-yang from the Mars,the states of Mercury are divided into yang five phases including jia,bing,wu,geng and ren,and yin five phases including yi,ding,ji,xin and gui.The yin-yang and five phases of human visceras is the result of the selective evolution under the influence of yin-yang and five phases of celestial bodies in hundreds of millions of years.The 5 years periodic movement of the Venus shows the five phases characteristics of the five zhongyun.With the addition of the yin-yang from the Mars,every zhongyun shows the yin-yang characteristics,which alternate once every other year.In a cycle of sixty years,the Saturn,Mars,Venus,Mercury and Jupiter show 15 pairs of independent yin-yang states,which is corresponding to the 15 pairs of yin-yang nayin five phases.

The traditional Chinese medicine deduces the 'Tianshi'based on the chronological era by heavenly stems and earthly branches,whose mechanism has been an eternal mystery.The references discussed the astronomical background of the chronological record of years by heavenly stems and earthly branches.In this paper,① A new law of the nature and human body is unitied was discovered.The relative position of the diurnal motion of the sun and the motion of five yao observed from the earth repeated with a precise period of 60 years,(1years,=360days).It lead the discussion of astronomical background for the chronological record of days and shichen by heavenly stems and earthly branches.② The yiyi calendar's chronological record of months by heavenly stems and earthly branches had the same astronomical background as the chronological record of years,i.e.the relative positions of yearly motion of the sun,the synodic month and the motion of five yao observed from the earth had an approximate cycle time of 60 years.③ The paper further discovered that the relative positions of the diurnal and yearly motion of the sun,the synodic month and the motion of five yao observed from the earth repeated every 240 years.This indicated the astronomical background for the fact that the yiyi calendar's sizhu heavenly stems and earthly branches group had a cycle time of 240 years.④ The traditional Chinese medicine should use the yiyi calendar's local time.
