Liu Yao's explanation

One, six hexagrams is a traditional divination method in China, which is often equivalent to eight characters. Basically, it is a popular name among the people, and forecasters generally call it gossip prediction. Its other names include "Huozhulin Prediction", "That Prediction" and "Zhouyi Prediction", which are called Zhouyi Prediction in many books.

Second, the reason why six hexagrams are called six hexagrams is basically from the form. After the completion of six hexagrams, there are six positions, which have many changes due to different dynamic and static reasons. Sixty-four hexagrams, one hexagram and six hexagrams. Because hexagrams are dynamic, divided into main hexagrams and changing hexagrams, the complexity of the evolution of six hexagrams is not inferior to that of eight hexagrams.

Third, there are many ways for Liu Yi to change his mind, especially at the master's place. Such as: money divination, yarrow divination, sound divination, name divination, orientation divination, etc. , can do it. What can divination do? According to the display of hexagrams, we can start with the number of images and predict everything in the world according to the restraint between hexagrams. From the perspective of modern science, this kind of divination is superstitious, but from the perspective of culture, it is still a wonderful work of China's ancient subjective materialism philosophy.
