What does "change" mean in divination methods?

As mentioned earlier, in divination, one side of a coin is used as the front (the side with words is used as the front) and the other side is used as the back. Put three coins together, shake them for a while, and then drop them. It should be noted here that when falling, you must choose a flat and tidy plane, so that the coin will be evenly stressed when it falls to the ground, and the accuracy of divination will be improved. The so-called "inversion" means that if all three coins are positive after landing, they are called Lao Yang, which means inversion. If they want to be negatively charged, the anode will be negatively charged. If all three coins are negative after landing, it is called Laoyin, which will change from Yin to Yang. The order of records is arranged from bottom to top, the first is the first, the second is the second, and the last is the last. After completing it six times, a "hexagram image" was formed. At this time, it is necessary to analyze several changes of six hexagrams: (1) If all six hexagrams remain unchanged, use the hexagrams of "original hexagrams"; (2) If all six hexagrams have changed, use the words of changing one's mind. (3) If there is only one change in six hexagrams, it should be judged by the change; (4) If five of the six strategies have changed and only one remains unchanged, the same rhetoric will be used to judge; (5) If the six hexagrams change more than the same hexagrams, they will be judged by changing their minds; (6) If the number of changes in the six hexagrams is less than the number of changes in the constant hexagrams, the change word in the "original hexagram" is taken as the judgment; (7) If the changes in the six hexagrams are equal to the unchangeable hexagrams, the hexagrams of "original hexagrams" and "original hexagrams" are used to judge. This kind of divination can only provide you with reference when you decide things, but practice has proved that the direction you ask is absolutely correct. As long as you work hard in this direction, you can get the best result you ask.
