Is there any change in yarrow divination?

Change, this is more complicated. You can look at Zhu's Zhouyi. Basically, it will not change when you shake it to Shaoyang and Shaoyin, but the old yin will change, and it depends on the words of the two hexagrams. Sometimes, if there are six Lao Yang, all six hexagrams will change, which can't be explained clearly in one or two sentences.
