The meaning of asking divination in Gregorian calendar.

If a person's relatives leave, what do these three hexagrams mean? Generally speaking, it is good to have a sacred divination, because when one asks, one of the three divinations (including three divinations) is good. If it exceeds, it is full yin divination or full yang divination, or both, which generally represents the concern of the deceased for the person. There must be a more detailed explanation, and I hope netizens can deeply explain it.
