What kind of book is the Book of Changes?

Hello, I am a beginner in the Book of Changes. Please forgive me if I don't speak well! The Book of Changes is China's first book. I believe that there is nothing to argue about, and it belongs to metaphysics. If the study of the Book of Changes is for divination, I advise you not to read it, because it will really fascinate you. The book of changes is very scientific. The ancients knew the laws of the universe without any instruments, and the principles of three changes, reason, image and number in the book were also very scientific, which showed the wisdom and ability of the ancients! Moreover, many languages of China people are also derived from the Book of Changes, such as No Three No Four No Chaos. You can find the answer in the book. In a word, The Book of Changes is a very scientific ancient book, and I believe everyone who has read it will agree with this view.
