The I Ching, also called Yi Jing, is a Chinese book which describes a philosophy used to consult an oracle. These two elements (the philosophy and the oracle) make it appealing and original. Originating from ancient China, it has been studied by numerous scholars, especially by Confucius, and has helped to the government of China for more than 2,000 years. As the Classic of Mutations, the I Ching was one of the Five Classics, that every scholar had to study in order to succeed at the exams which would allow them to obtain a government job.
