About psychics and yin and yang

From my understanding... a psychic is a person who has the ability to see creatures in the yin and yang worlds, but it may only be able to see, while an onmyoji has the ability to see. The ability to eliminate demons and spirits, but whether you can see spirits or monsters is not certain. For example, Fujiwara Toshiji in Young Onmyoji is an onmyoji who has no ability to see ghosts~ That's about it...

As for the real Onmyoji in Japanese history, they also had a very important position in that era. They recorded the calendar, weather and so on~ You can try Baidu in this regard~ The experts’ explanations are very comprehensive~ I have only a little knowledge , showing off one’s embarrassment~
