One day, Confucius got a book called the Book of Changes:> ```````````` Look at the answer.

One day, Confucius got a copy of Yi written 1000 years ago. He found that the way people talked and described before 1000 years was very different from that of his time, and most people could not understand it at all. In order to make people understand this book, he annotated the contents of Yi in a way that people of his time could understand, and wrote a book called Ten Wings. It has been circulating for 2500 years, and people are used to calling the Book of Changes and Ten Wings as one book, which is called the Book of Changes. It's a pity that a good philosophy book that teaches people to be human has been endowed with fortune-telling function by superstitious people. Nowadays, most people only know fortune telling when they talk about the Book of Changes, but they don't know the real function of the Book of Changes.
