There are several aspects involved in answering this question. First, the Book of Changes is difficult to learn. One of the difficulties lies in the lack of detailed records in ancient history. The Book of Changes quotes many ancient stories, for example, the divination of deer is safe, the need of divination involves rivers, Dee returns to his sister in Thai divination, and Yi loses cattle in travel divination. , are based on ancient stories to discuss the wisdom of philosophy or ways of doing things. These stories are more difficult to understand because they lack detailed records. Secondly, the grammar and expression of Shang dynasty also changed, because the ancient productivity was low and the writing tools of books had no paper. The engraving and preservation of bamboo slips are problems. It is impossible to write in all spoken languages, but a refined language is needed. If you can omit it, don't write more. Therefore, to restore to modern language, it is necessary to supplement the omitted part, which is also one of the difficulties in restoring the omitted part at that time. The third is the content of Chinese language expression. After thousands of years of changes, it is not easy to find the original meaning of Chinese characters. The only authoritative interpretation of Chinese characters that can be found is to explain Chinese characters in words, and it takes some skills and time to understand Chinese characters. Fourth, when the Book of Changes expresses its meaning, it is not a simple text, but also a hexagram with opposite yin and yang. The arrangement and combination of these hexagrams and hexagrams have complex meanings, which need to be comprehensively interpreted by dialectical and related methods. It is more difficult to interpret hexagrams and hexagrams than language. From the above main aspects, it is difficult.
Secondly, on the surface, the Book of Changes is a book of divination. When people encounter difficulties and need to choose, they can find corresponding words according to the names of diviners, so as to interpret good or bad luck. The reason is that most people in ancient China did not study. Studying at school is the exclusive right of the upper class. It is already a great thing that someone interprets the Book of Changes. Thirdly, the Book of Changes is an encyclopedia, which contains 64 hexagrams and 384 hexagrams, plus two useful hexagrams, one * * * is 386 hexagrams. Its rhetoric involves all aspects of life, and few people can have such a comprehensive contact or experience, let alone experience and experience, and they can get it with a little knowledge. Even experts who study the Book of Changes, many people have spent their whole lives, and they don't always understand it. If students are graded according to the current school, and 60 points is considered as passing, I think those who can reach more than 80 points are experts, because few people can use all the ideas and methods of the Book of Changes for a lifetime.
Thirdly, I learned the Book of Changes when I was young, so I read books because I have no life experience. Many books have given me many mistakes in interpretation and understanding, and it is difficult to distinguish them because of lack of practical experience. When I know the truth, I don't want to change my behavior, which also affects my understanding of the Book of Changes.
The most important point is also one of the characteristics of the Book of Changes. Because the recorded words are few and precise, they can be used in many ways. For example, the "Yuan Henry Zhen" mentioned in the divination of dry branches originally refers to the persistence of seeds from germination, flowering, fruiting, and then maintaining to germination again. But it can be extended to many aspects of life, such as moral cultivation, skill improvement, physical exercise and so on. The natural phenomenon of "Yuan Henry is true" can be cited to interpret the wisdom of being a man and doing things. Therefore, learning the Book of Changes requires more insights.
These are the main reasons why many people are learning the Book of Changes, but few people really understand it.
