Are you asking about the meaning of Bazi? How to calculate the God of each person's horoscope? This kind of question has different answers because everyone has different teachers.
According to my own understanding, the horoscope's God is also the balance point of the horoscope. As the great fortune enters the fate, if the fortune is the horoscope's yongshen, this destiny may be in terms of fame and fortune. You will reach the peak of your life, but there is no guarantee that you will be safe once fame and fortune are achieved. Often some people will encounter misfortunes in their fortunes, but they are more successful in fame and fortune. The purpose of using gods is to balance the relationship between the sun master and the officials. The ancients also said: "The sun is the main focus, and the wealth and officials are the focus." Never said that the sun is the main focus, and life and death are the focus! Therefore, the role of Yong Shen is sometimes confusing. Even if you come to like Yong Shen luck, not only does it not improve your fortune, but it turns out to be very miserable! Is it wrong to use God? This may not be wrong in the original horoscope, but once the luck and the fleeting stems and branches interact, then "joy is not eternal joy; taboo is not eternal taboo." Therefore, the ancients did not pay much attention to the use of gods when looking at fortune, but focused on the gods of good fortune and evil. The teachings about using gods were also done after the Qing Dynasty. It turns out that "The Essence of Ditian" also said: "Human Yuan is the God of Yongshen", so let's call it Yongshen for short.
Nowadays, there are many things to say, but only if the calculation is correct, it will be useful. If the calculation is incorrect, even God will not work!
