What do Kunzao and Shensha mean in the eight characters?

Kun means woman, and Kun calls out the eight-character arrangement of women. Ghosts and demons are fixed judgments formed by the matching of eight characters, such as Gai Hua, nobles, etc. Ghosts and demons generally have a fixed format. Among them, it is more complicated and there are many kinds, so it is difficult to judge, so some fortune tellers simply don't look at the gods, but only look at the coordination of the eight characters.
