Divination by the Eight Diagrams has been in use in China for centuries. It uses the I-Ching's capricious patterns of Yin-Yang Eight Diagrams to envision the future and the progress of any given event. Divination starts at the location of "Four Seasons and All Sides" in I-Ching to determine the direction of a given event. Then, based on the combination from the 64 patterns, an answer is obtained. There are many divination methods such as using rice, tortoise shell, coins, and birds; the results are mostly based on the deduction method of the 64 patterns of Chou-I.
