Questions about divinatory symbols (experts come in)

The first case: only one of the six hexagrams has changed, that is, five of the six numbers are either 7 or 8, and only 1 is 9 or 6. At this time, the quality is judged by the words of this hexagram.

The second situation: there are two kinds of changes, which we have just encountered, so I won't go into details here.

The third case: if there are three changes, you can't judge them by the changed words, but by the original words and the changed words, mainly the original words.

The fourth case: there are four changes, and at this time, the good or bad is judged by two unchangeable words.

The fifth case: there are five changes, and the good and bad are judged by the words of those who have not changed.

The sixth case: there are six changes and two cases of scoring. First, the six hexagrams are all yang hexagrams (constituting dry hexagrams), or the six hexagrams are all yin hexagrams (constituting Kun hexagrams). Then, if it is a dry divination, you can judge good or bad by the word "Yong Jiu" in the dry divination, and if it is a Kun divination, you can use the word "Yong Liu" in the Kun divination. What are "using nine" and "using six"? Let's talk about it in detail. Second, in addition to these two situations, the other six hexagrams have completely changed, and the words of change of heart are used to judge good or ill luck.

The seventh situation: the six hexagrams have not changed, and then the hexagrams of this hexagram are used to judge good or bad luck.
