What is the most accurate divination?

I think prediction is just a tool, not the most accurate one, but how the forecaster practices it. Prediction itself has its own characteristics. For example, The Book of Changes of Plum Blossoms is said to have been written by Shao Yong, a scholar of Yi Studies in the Song Dynasty. It is a book based on the mathematics in the Yi-ology and combined with the "iconology" in the Yi-ology. According to legend, when Shao Yong used it, every hexagram must be correct, and it always works.

The plum blossom book exchange has four characteristics: simplicity, quickness, easy learning and miraculous effect. It is a primary and advanced forecasting method, which quickly transforms testability into productivity, is suitable for the ever-changing information society, and is highly valued by Yi-ology scholars.
