Can the Book of Changes (that is, the Book of Changes) be used to learn Feng Shui? Is there anything about Feng Shui in the Book of Changes? Is the original Book of Changes difficult to understand?

I ching can't be used to learn feng shui. I ching mainly includes four aspects: image, number, reason and occupation. However, some geomantic omen uses some things in the Book of Changes, such as divination in successive days, the book of Hutuluo and so on. . . The Book of Changes contains profound knowledge, covering almost everything we see or can't see. For example, the Book of Changes is like a dictionary, and the geomantic omen we are talking about here is just one or several words in this dictionary. . . The original book of changes is really difficult to understand. Even if you have a high level of ancient Chinese, you will still explain it in some places and you will encounter great problems. There are too many controversies about the Book of Changes from ancient times to the present. As Confucius said, "Different people have different opinions." Even Confucius used Confucianism to explain Yi, not to mention us.
