The Book of Changes represents twelve endless words.

The essence of Yi is natural vitality. Eight thousand years ago, when the ancestors of China lived in harmony with nature, they were surprised to find that there were some magical and mysterious figures in the vast universe, which were closely related to the growth of life in the universe. People reverently worship the gift of this day with awe. With the help of bionics, China ancestors created the glorious sacred book of mankind-life is easy, what a great pioneering work! Unfortunately, up to now, more and more Yi-ology enthusiasts have given up the study of the essence of Yi and turned to explore the divination function and cultural function of Yi, which is distressing. Although the Yi Dian originally invented by the Chinese ancestors was so crude, there were only Yin and Yang symbols, and nothing else, but the essence of the original Yi Dian still stayed on the mysterious numbers represented by Yin and Yang symbols, just as Lao Tzu said: Tao gives birth to one, two, three and everything. The phenomenon that human beings use divination to predict good or bad luck itself can reflect human desire for the continuation of life. No matter what the predicted result is, in the face of changing nature, people should always be cautious and humble in order to move forward smoothly in the journey of life. Therefore, divination is only a function of Yi, not its essence. A slight difference between heaven and earth. Form cannot represent content, but can only be used to express content.
