Count hexagrams with coins and shake hands six times, all of which are positive and negative. Which hexagram should it be?

When you say no, you don't mean two behind and one in front. If there is, it means there is less yin. This is the Kun hexagram, and the six hexagrams turn to dry hexagrams. The specific method should be combined with what you want to measure, but no matter what you measure, you have shown that it is a complex and repetitive thing.
