Excuse me, what does the eight-character yang spirit mean?

First of all, heavenly stems and earthly branches Yin and Yang are a pair in the eight characters.

Such as wood, wood, wood, wood, wood, wood, wood, wood.

So as long as this yin and yang is not all yin and yang.

There is no problem of more yin and more yang here, but there are some problems of combination. For example, the eight characters are all earth, which is called earth gold, so it is best to study the eight characters.
