Why should I shake the Qian Qi hexagrams in the Book of Changes?

Whether the divination with the Eight Diagrams in Zhouyi is effective depends on whether the method and steps of divination are correct and whether the judgment and choice of six hexagrams are appropriate. There are many ways to start divination. I think for ordinary people, using Chinese strokes and shaking money are the two easiest ways. The difficulty in using Chinese character strokes is to be familiar with the writing rules and the strokes should be accurate. As long as the strokes are ok, the hexagrams are also accurate. However, the cleverness of hexagrams lies in their movement and change, that is to say, every hexagram with six hexagrams must have a movement, or the change from Yang to Yin and from Yin to Yang. As long as the total strokes are accurate, the determination of changes is usually reliable. But generally speaking, it is easy to make mistakes when changing Qian Qi's hexagrams. Let's take a look at Qian Qi's divination rules: take three coppers, shake them well, and throw them down six times. The main point of picking hexagrams every time is that the side with words is a cross, the side without words is the back, and only one back of the three fallen copper coins is recorded as "-",which is a single yang; The double back is marked as "-",which is divided into yin; Draw a circle of "Ф" three backs, which is Yang; For moving, it becomes yin; There are three words marked "X", indicating that the intersection is yin; And in order to be moved, it became Yang. According to the usual understanding, all three copper coins are upside down, which should be full of yin or pure yin, and should be recorded as "-". On the contrary, all three copper coins are face up, which should be all-yang or pure-yang, and should be recorded as "-". However, Master Zhouyi and experts and scholars did the opposite, calling them Lao Yang and Laoyin respectively, and euphemistically calling them dynamic. This is not difficult to understand. When the actor changes, the extremes will be reversed, the whole yin will change, and the whole yang will become the old yin. However, if you think this is the final decision after the change, it is all wet. Let's give an example to explain it in detail. The record of someone throwing copper coins six times is as follows: six coins, an "X", is the old yin.

Five "-"is positive, four "zero", three "-"is negative.

Two hexagons and one "-"is the initial split into yin hexagons and one "Ф" is Lao Yang.

According to the above records, we can get the following ▅ ▅ ▅ ▅ ▅ ▅ ▅ ▅ ▅ ▅ ▅ ▅ ▅. As far as this hexagram is concerned, if the first, fourth and sixth hexagrams are dynamic, the hexagram images after mutual conversion should be: ▅▅▅▅▅▅▅▅▅▅▅▅▅▅. The question now is, since If this can be done, there will be no problem of change, thus avoiding unnecessary trouble. This question may be ridiculous, but I just want to ask experts at random to dispel doubts and let everyone know.
