How many uses does the sixty-four hexagrams of Zhouyi have?

The Book of Changes is a profound knowledge, but it is just a primary school question. The essence of these sixty-four hexagrams is the generalization of the laws of all things in the universe. 64 is an imaginary number, that is, it is alive, not just 64, but can be summarized as 64. Just like the "three" in "Three people must have my teacher".

As for how to use it, no one dares to say that he fully understands it. But the use is by no means fortune-telling and geomantic omen. Those who use it to tell fortune are also showing off if they don't learn.

The real use of Zhouyi is to let people see through the universe and life. For example, in recent decades, the west has made progress in gene, and found the double helix structure and four nucleic acids: adenine, guanine, cytosine and thymine. After these four nucleic acids are arranged and combined, 64 basic gene combinations can be formed.

In other words, there are only 64 kinds of genes, but they can form everything in the world. Further, there are four kinds. Further, there is another. This basic element is called Yin and Yang. Why is Yin and Yang one thing and not two? Because Yin is Yang and Yang is Yin! Without men, there would be no women; No big, no small. It is unity of opposites and inseparable. In fact, not only animals and plants, but everything in the world is made up of yin and yang.

For another example, in the theory of traditional Chinese medicine, many diseases can be diagnosed without looking at the lesion. What does it depend on? In fact, Chinese characters are related as long as they have the same pronunciation, and "medicine" and "medicine" are homologous. The earliest medicine was witchcraft. For example, if the patient has a bad heart, where can he go to see it? Look at the root of the nose. If there is a slight depression or redness, it means that there is something wrong with the heart (I don't know much about it, just say something). Why? Because the meridians are the running route of the human body's "Qi", the heart's "Qi" reaches that position, so it can be seen through the nose. But meridians are not pipes, but routes. Why did Qi go there? Who made the rules? Medicine has not analyzed this problem, which is also difficult for Chinese medicine to explain. In fact, this is Yi. It's not where the gas goes, but there is a universal connection between everything. The connection between the heart and the nose is the most intuitive. After the predecessors' summary, everyone can understand. However, the relationship between official career, marriage, children and facial structure is difficult to understand. A few years later, the relationship between the American election and the astronomical phenomena is even more difficult to understand. In fact, although it seems impossible, these are all in the same strain.

Of course, what I'm talking about is just a scratch on the road to Yi Xue. In Zhouyi, all roads lead to Rome. No one dares to say that they know everything, but they all have their own reasons. How much they can understand depends on everyone. For some people, it is omnipotent, while for others, it is useless.

PS: I am against divination, but in order to show that I am not an empty theorist and critic, I made a hasty divination through the words used in your question. On the whole, your situation is not good. As a hungry person, you may be under great pressure and everything is not satisfactory. But these things have been understated when you post. They are very moral and have a lot of things. Therefore, the unpleasant days are about to pass.
