What kind of person is the teacher of Yin and Yang?

Master Yin and Yang, to put it bluntly, you might as well call a fortune teller. It seems impossible to call them illusionists and gods, but it is not accurate enough.

Yin and Yang teachers watch the stars and people.

Both azimuth measurement and divination. You can spell, you can use magic.

They have the ability to summon ghosts, which is invisible to the naked eye-it is not difficult to communicate with fate, souls, ghosts and the like.

Even the DPRK has such posts, and the imperial court has Yin and Yang Liao.
