Why is Ji Chang's divination so accurate?

The source of China's scientific thought and culture is Yi. The Book of Changes first put forward the definition of "astronomy". Although the Book of Changes was written in the Warring States period, it really expressed the thought of destiny formed in the Zhou Dynasty. Yi said: "When looking at astronomy, we should observe the changes of time." Yi Congli said, "The sky is hanging, and saints see good or bad luck." And so on. The thought of Yin and Yang originated in the Western Zhou Dynasty had an important influence on the development of astronomy in China. Zhouyi has a long process of formation and development. What is called "River Map" and "Luo Shu" by later generations is the expression of burning Oracle bones and the reflection of the mutual connection and infiltration of rational thinking and image thinking realized by ancient ancestors in their long-term life and divination practice. According to legend, it was summed up by Fu, who arranged yarrow repeatedly and painted it as gossip, covering all the phenomena between heaven and earth, which was primitive and relaxed. Later, it is said that after careful study by Zhou Wenwang, it was standardized and sorted out, and it was interpreted as 64 hexagrams and 384 hexagrams. With divination and diction, it is called Zhouyi. It uses simple images and numbers, and the opposite changes of Yin and Yang to explain all kinds of complex social phenomena, and displays thousands or even infinite numbers, which has the characteristics of using few to show many, using simplicity to show many and being full of changes. It is called "Yi", and Zheng Xuan explained that it has three meanings: one is simplicity, the other is change, and the third is difficulty. That is to say, The Theory of Everything has changed, the phenomenon is constantly changing, and some of the most basic principles will not change, which abstracts rich and simple dialectics from the dialectical development of the objective world. In the late Spring and Autumn Period, Confucius explained and discussed the Book of Changes and completed the Ten Wings, namely the Book of Changes. In this way, Zhouyi has developed into a profound philosophical work about the change of the universe.

In layman's terms, Zhou Wenwang and Jichang are the grandfathers of fortune telling. Of course, they are accurate! ^_^
