What is the operating principle of birthday?

It is the cyclical and regular changes of climate that affect people's physiological development, leading to different types of physical conditions and different lifestyles. There is a high probability that climate change will affect people's physical condition by more than 50%.

Jin Mu's five major planets, water and fire, periodically change their distances from the Earth, leading to periodic climate changes.

70% of people's birth time will be affected by climate (including year, season and hour).

Different seasons have different climates, different years have different climates, and different times have different climates.

Therefore, according to the time of birth, you can roughly judge that someone's physical condition type and susceptible diseases are 60-70%. You can also judge which types of diseases are easy to be prevalent in a certain year.

The basic method principle comes from Huangdi Neijing, including two schemes: meridian stream injection and five movements and six qi.
