Divination and divination in the Book of Changes, as a means of prediction, are based on the principle of "probability" to simulate the symbols of yin and yang structure of the measured object, and then restore the object itself according to certain norms and criteria (that is, restore the abstract divination and divination into concrete things), because there are thousands of years of historical data and rich philosophies in the Book of Changes as theoretical basis.

In breadth and depth, it far exceeds the forecast of any other industry. It is precisely because its predictive function is beyond people's imagination and cannot be explained due to the limitations of modern scientific detection methods that some people can't believe it.
