"Zhou Yi" includes two parts: "Sutra" and "Biography", and its content contains heaven, earth, and man, which is broad and profound. It has had a profound and far-reaching impact on China's politics, economy, culture and other fields for thousands of years.

In the last years of Yin Shang, King Yin felt the threat of the vassal state of Zhou, so he found an excuse to imprison King Wen of Zhou in Jinli. In order not to interrupt the culture inherited by his ancestors, King Wen rearranged the "Yi" handed down by his ancestors in prison and deduced sixty-four hexagrams.

The society in which King Wen of Zhou lived at that time had begun to transform from the contradiction between man and nature in the primitive society to the contradiction between people. His study of the Book of Changes began to change, transforming from nature-based to human-oriented, focusing on the relationship between man, society, and nature.

He expressed the symbols of the sixty-four hexagrams in words, and the content of each hexagram also included hexagram paintings and hexagrams. Later, King Wen's fourth son, Zhou Gong (Zhou Gongdan), explained the words of the sixty-four hexagrams, which formed the "Zhou Yi".

The "Sutra" part of "Zhou Yi" is composed of 30 hexagrams of "Shangjing" and 34 hexagrams of "Xiajing", and the upper and lower "classics" are a total of 64 hexagrams, each of which is composed of hexagram paintings, titles, hexagrams, and epigrams.

The 30 hexagrams in the above scriptures are: Qian, Kun, Tun, Meng, Need, Litigation, Division, Comparison, Xiaochu, Xu, Tai, No, Tongren, Dayou, Qian, Yu, Sui, Gu, Lin, Guan, Zheng, Ben, Peel, Fu, Wu, Da Chu, Yi, Daguo, Kan, and Li.

The 34 hexagrams of the lower scriptures are: Xian, Heng, Dun, Dazhuang, Jin, Mingyi, Family, Look, Jiao, Solution, Benefit, Profit, Scale, Extraction, Rise, Sleepy, Well, Ge, Ding, Zhen, Gen, Gradually, Guimei, Feng, Lu, Xun, Dui, Zhuan, Jie, Zhongfu, Xiaoguo, Jiji, Weiji.

The 30 hexagrams in the upper classic are headed by the two hexagrams of Qian and Kun, reflecting the author's idea that "there is heaven and earth and then there are all things", and the two hexagrams of Qian and Kun give birth to the remaining 62 hexagrams.

The 34 hexagrams of the Lower Classics are first with the two hexagrams of Xian and Heng, and end with the two hexagrams of both Ji Ji and Wei Ji, reflecting the author's idea of "endless life" arising from the development and change of things.

After King Wen of Zhou, more than 500 years passed, until the end of the Spring and Autumn Period, Confucius and his disciples and Confucianism used the method of taking images and meanings to comprehensively interpret the "Book of Changes", and compiled ten articles of Yi Ci, namely "Yi Upload", "Yi Xia Chuan", "Xiang Upload", "Xiang Xia Chuan", "Xiang Xia Chuan", "Department of Words Upload", "Department of Words", "Wenyan Chuan", "Preface Hexagram Biography", "Saying Hexagram Biography" and "Miscellaneous Hexagram Biography", called "Ten Wings", also called "Yi Chuan".

The "Sutra" of "Zhou Yi" actually refers to the "sixty-four hexagrams", that is, "the sixty-four hexagrams of Zhou Yi", also called "the sixty-four hexagrams of the Book of Changes"; Of course, in addition to the sixty-four "hexagrams", there are also "hexagrams" and "hexagrams".

We know that each hexagram of the "Sixty-four Hexagrams of the Book of Changes" has six "yao", so there is a total of sixty-four times six, which is equal to three hundred and eighty-four "yao".

In addition, although the two hexagrams of "Qian" and "Kun" are also six hexagrams, they each have seven "hexagrams" (the "use of nine" of the Qiangua and the "use of six" of the Kun hexagram, there is no "line", but there are "words"), so the entire lineup of the "Sutra" is - sixty-four "hexagrams", plus sixty-four "hexagrams", plus three hundred and eighty-six (384 + 2) "hexagrams", and that's it.
