The Book of Changes is the theoretical source of natural philosophy and humanistic practice in China's traditional ideology and culture, the crystallization of China's ancient thoughts and wisdom, known as the "source of Tao", the study of ancient emperors, and the required skills of politicians, strategists and businessmen.
The Book of Changes is an outstanding representative of China traditional culture. The vast and the subtle are all-encompassing. According to Zhou Benji's Historical Records, King Wen was imprisoned and the eight diagrams were sixty-four hexagrams. ?
In other words, King Wen (Bochang) was framed by Hou Hu, who was imprisoned by Yin Yi for seven years. Xi Bochang devoted himself to studying the Eight Diagrams of Yi Studies in prison, and through the superposition of Eight Diagrams, he popularized 64 hexagrams such as "Walking Heaven, Wei Kundi, Shuileitun and Landscape Dream" recorded in Modern Yijing.
The preface of the sixty-four hexagrams in the Book of Changes is based on eight hexagrams. The predecessors' main understanding is "innate gossip's theory" and "acquired gossip theory", each with its own characteristics, but the connection with the sixty-four hexagrams seems to be connected.
Later, someone put forward the concept of "even right, not repeating" for the sixty-four hexagrams, which can be described as a great progress. It pointed out some internal relations of the sixty-four hexagrams. However, this concept is also flawed, because its formulation of "seeing only trees but not forests" failed to systematically solve the problem of divination order in the Book of Changes.
