The ancients used dry branches to mark the days. The dry branches were composed of ten dry branches (A, B, C, D, H, N, N, D) and twelve earthly branches (Zi Chou Yin Mao, Shen You Xu Hai at noon), such as Jia Zi, E Chou, C Yin and so on. , can be used to mark the year, month and day, and 60 dry branches cycle back and forth. In other words, Wushen Day is the main branch of that day.

The so-called using God is a special term in China's traditional four-column eight-character prediction, which refers to the heavenly stems or earthly branches used to remedy the shortcomings of eight-character prediction.

Is the god of all things. For Japanese stem, eight characters are a kind of five elements, which can make up for disadvantages, save bias or promote success. It is used to analyze the use of the eight characters in the Universiade and the fleeting time to maintain the "neutralization" of fate itself and achieve balance and circulation.

The four-pillar life game takes the use of God as the core, and whether the use of God is sound or not affects people's life. Lifelong remedy or not affects a person's life. It is not enough to use God's strength. Those who use God in four pillars or in four pillars punishment can turn evil spirits into evil spirits, and those who control evil spirits are all western gods. The four pillars don't need god, but they have to rely on luck to make up for it. For the four pillars, the five elements of life are balanced and there is no shortage of gods, so their lives are relatively smooth and there are no ups and downs.

This theory holds that the five elements in the eight characters are too strong or too weak, which is not good, especially for the sick. God is to the constellation what medicine is to man.

On the day of Wushen, you used God to make up for the lack of heavenly stems and earthly branches on this day, so as to balance it.
