How does plum blossom change its mind?

1) mutual divination: the lower divination is composed according to the second and third divination of the main divination, and the third and fourth divination are the upper divination. For example, in your picture, 234 hexagrams are root hexagrams and 345 hexagrams are fork hexagrams.

2) Change your mind: There are two ways to do this. According to the plum blossom easy number algorithm, if there is no hanging, there is only one moving boat. If the artery is yin, it will be yang, and the rest will remain unchanged. For example, in your picture, the main divination is exchange and the fourth divination is movement. So the fourth one used to be horizontal, but now it has become two horizontal ones, and the other ones remain the same, so it has become water on the ridge, and the next one is still a shock. If it is a copper coin, there may be many changes.

3) Exercise is the main basis for judging things.
