What do the numbers in front of each sentence in the Book of Changes mean? Can the Book of Changes really tell fortune? How to use it?

Nine is yang and six is yin. One, two, three, four, five and six are the positions of each.

For example, the top hexagrams are Yang hexagrams (Yin hexagrams) and the top nine hexagrams (top six hexagrams).

Strictly speaking, I ching can't tell fortune. However, if you are familiar with the principles of the Book of Changes, you can learn from its knowledge.

Speculate about the development of things.

Everything else is a lie or a misinterpretation of ignorance!
