How to look at the divinatory symbols after Zhouyi's divination is calculated?

no, I don't think so. Three coppers are seen together every time they are shaken out. If you shake the word "single", it is Yang (Shao Yang), and it is recorded as "-"; If the word "torn down" is shaken, it is yin (less yin), and it is recorded as "-"; If the three shakes are all on the back, it is called "heavy", which is Yang Yao (Lao Yang) and recorded as "O"; If all three words are shaken, it is called "cross", which is called yin (old yin) and is recorded as "X". So if you shake it six times, you can get a hexagram. It's not that there are 18 yin and yang. Among them, Laoyin and Lao Yang are dynamic, but when they move, they change. If they get these two dynamics, they will change their own yin and yang, that is, Yang becomes Yin and Yin becomes Yang. If you change, you will change your mind. In this way, you will change your mind. In ancient times, this method of divination was called "substituting money for money". Fifty yarrows are used as divination in the week, which is what is called "the number of great Yan" in the copula. However, it takes a very complicated process to use fifty yarrow to make divination. Only after "four camps become easy" and "eight out of ten become divination" can a divination be obtained. In the Tang Dynasty, copper coins were used to shake divination instead of yarrow.
