Judging the eight characters is to compare other branches with the Japanese trunk as the center.
As far as your horoscope is concerned, everything is centered on the "C fire" in the solar column, and the "Jia Mu" in the annual branch "Jiayin" is Yang, and the "C fire" belonging to Yang in the afterlife is called "Owl God". There are three branches "A, C and E" hidden in the shade of the annual branch "Jiayin", and A-born C is the "owl god"
Let's talk about Chen Wu again. The relationship between Wu and C is described as "God of Food", and there is "E" hidden in it. B belongs to Yin wood, and Yin wood gives birth to Yang fire C, which is called "positive seal", C gives birth to E as "god of food", Gui water belongs to Yin, and Yang Kehuo C is "official".
Other similarities, these are all terms to analyze the eight characters, so you don't have to pay attention to them if you don't study them.
Long-winded for your reference.
