Why did the ancient people invent the Book of Changes, and now people still don't fully understand it?

Because of the language barrier, although our modern Chinese characters evolved from ancient times, modern people still don't know much about ancient Chinese characters, let alone the Book of Changes composed of Chinese characters at that time. The composition of the characters in the Book of Changes cannot be interpreted by ordinary people unless they have enough knowledge, and modern people also have modern civilization to learn from. In addition, the Book of Changes is extensive and profound, so it is naturally impossible to fully understand it easily.

Because the description of the Book of Changes is abstract, in short, the language description in the Book of Changes is difficult to understand, and the description is not very detailed, but the sentences are still very complicated. Just like fortune telling, let us understand math problems. Originally, math problems were difficult to understand, and it is even more difficult to understand math problems in the existing way, so people haven't fully understood them yet.

Because it needs to be applied in practice to understand. The way to understand the Book of Changes is not to interpret it, but to apply it in real life. At this time, you have the password to understand the Book of Changes, but this is only the initial password, and there are layers of passwords waiting for you to unlock. At this time, with the law summarized in the Book of Changes, the rest of the passwords can be easily unlocked, but in real life, you don't have to use the time of the Book of Changes to open the password, you can choose other ways to decrypt it.

Because the Book of Changes contains too much knowledge, I think not only modern people didn't understand it, but also ancient people didn't fully understand it. Coupled with modern people's worship of science, it is natural that they cannot agree with many places in the Book of Changes that have no scientific basis. If they don't agree, I think the Book of Changes is more difficult to understand. So I fully understand why modern people have not fully understood the Book of Changes.
