What is the ritual method of divination in the Book of Changes?

I read a book: Ceremony: Wash hands and burn incense. Be sincere, be sincere. Methods: For convenience, the author uses the method of bean divination to show that learners can calculate as long as they have numbers, such as rice, peanuts, stones, bamboo heads and bamboo leaves. Even if you go out for an outing, you can catch a handful of leaves. As far as I'm concerned, I can carry rice or soybeans in a small glass bottle with me, and I can do divination anytime and anywhere. Some people will also prepare a blank business card with numbers from one to six written on it. One, three and five are odd numbers and are regarded as yang. Two, four and six are even numbers and are regarded as yin. After the six business cards are fully shuffled, you should carefully draw a card that is consistent, then mix this card back to its original place for the first time, draw a second card for the second time, and so on, and you will get any of the 64 hexagrams completely. If you want to change your mind, draw the seventh card. If the number of hexagrams in this card is five, then it will become five, and Yang will become Yin. Yin becomes Yang, which can be imitated.
