The accuracy of six hexagrams is pitifully low.

Six hexagrams is a method of divination and supporting relatives, which is not a complete picture, so it needs one thing, one industry and standardized operation, represented by adding and subtracting divination. Network divination, based on the method of providing for relatives by divination, cannot reach the natural state at will. To be sure, it is good that the accuracy of one thing and one account can be stable at 80% to 90% for a long time. Don't brag, there are no immortals in the world, only people with dim eyes.

The true six-hexagram divination is the most fulfilled and the most explanatory. It is just divination other than divination. This technique has been kept secret for generations, and there are occasional traces in the Book of Changes of Plum Blossoms, Duan Yi Tianji and other books. If the divination other than divination is combined with divination relatives, the six-hexagram model will be three-dimensional.

Six hexagrams is one of many forecasting methods, which can be calculated from astronomy, geography, personnel and other aspects.

If it is fortune-telling, personally, the prediction method specifically for fortune-telling will be better. As for authority, I can't say. The six hexagrams you mentioned were invented by Fang Jing in the Han Dynasty, right? You started divination with copper coins, and you asked the fortune teller to shake it himself?

There is a saying that it is easier to start divination than to break it. In the eyes of top experts, the methods are just different paths. As long as the skills are sufficient, I believe that different paths should point to the same forecast trend.
