The preface to the sixty-four hexagrams of the Book of Changes seems to be a long-term authoritative topic. There is an introduction to Yi Gua in Yi Chuan Shi Yi, which specifically discusses the arrangement order and significance of the sixty-four hexagrams, which should be beyond doubt. However, after careful analysis, things are not that simple. Because as we all know, the emergence of the Book of Changes is hundreds of years later than the Book of Changes, spanning a historical era that cannot be ignored. In fact, the Book of Changes is a binding book, which consists of two different parts: the Book of Changes and the Book of Changes. The latter is the annotation, interpretation and deduction of the former by later generations hundreds of years later. The two can't be treated equally when studying. For example, many papers written by modern people for A Dream of Red Mansions may not conform to Cao Xueqin's original intention.

The popular version of the preface comes from the preface to the biography of hexagrams. Gan, Kun, Tun, Meng, Need and Litigation ... are the products of the rise of benevolence, righteousness, morality and ethics in the Spring and Autumn Period, focusing on philosophy. This may not be in line with the original intention of the Book of Changes produced in the Western Zhou Dynasty. 1973 The silk book Zhouyi unearthed from Mawangdui Han Tomb has different orders: key (dry), woman (nothing), ceremony (achievement), lawsuit, and fan ... This is an order close to the original idea in different palaces.

In fact, according to the principle of binary numbers, the combination of yin and yang of the sixty-four hexagrams clearly stipulates its own inherent order, which truly reflects the significance of the Book of Changes. Below, only the yin is 0 and the yang is 1. From bottom to top, from right to left, a binary number sequence is formed, which is usually called Fuxi hexagrams. As a reordering of heaven and earth, upper yang and lower yin, this number of hexagrams is compared with other popular books, silk books and Najia laws as follows. As the basis of divination, this sequence may be more suitable for understanding the meaning of divination. What's the secret of this sequence? This is a question worth discussing.

Octal algorithm has been widely used in Zhong Yi. An example is the eight-point divination in "Meihua Yiju". Dividing by eight and taking the remainder is a standard algorithm for converting decimal numbers into octal numbers. It can be seen that the exhibition has always been carried out in octal divination order. At present, the popular version of the hexagram sequence has nothing to do with the exhibition, and it does not conform to the original intention of the Book of Changes.
