First: Four pillars, Yuan Haiziping, Sanhui, Mu, Poor Sword, Zi Quan, exploring the source of numerology, students, these books can be read intensively.
Beijing Normal University has a copy of Astrology, which can be read.
The second category: Book of Changes, which is a basic book, must be read, such as Book of Changes, Book of Changes Compromise, Book of Changes Notes, Book of Changes Shu, Book of Changes for the Past, and then read Heluo Lishu, Book of Changes for Plum Blossoms, Book of Changes for Najia, Supplement and Gaodao Yishou. There are already several methods in this book. Duan Yi in Gaodao had the style of Yi Bu in Tang and Song Dynasties, and Yi Shu in Plum Blossom was the way of Song and Ming Dynasties. Addition and subtraction were practical and easy to learn.
I want to say a few more words about Zhouyi. It's really hard to know the difference between Ming and Qing Dynasties, Tang and Song Dynasties, Ming and Qing Dynasties and even the pre-Qin Dynasty. But for those who want to learn divination, it is enough to learn only the Ming and Qing Dynasties. Yi Xue is changing, so is fortune telling. This is heaven.
The third category: Shi San, this is the stream of the Book of Changes. However, people who are not the Book of Changes and Taiyi have only read one book.
These two books, The Secret Book of Daoism, Zhuge Liang's Jin Xin Yu Jing, and The Complete Book of Daoism are enough. The rest books, such as Daoism Tongzong, Qifa, Qimen, and investigation at the altar, can be turned over at will. You can ignore the magic and let the big fairies play.
Qimen theory, metaphysics in ancient times, lacks theoretical innovation and few examples. Learning is not easy, it's up to you. Don't covet magic, always put practicality first.
Six-person class, this suggestion should be studied hard and there are many books. Taiwan Province Province seems to have published the complete works of six benevolence, which I have never seen; As far as I know, there are The Complete Works, The Guide, The Book, The Origin, Notes, Collection and Commandment of Six Kings, which are worth studying. I'm afraid it will take ten years to understand these books. After ten years, you will have your own judgment, and I don't need to say it.
There is also a small six, which is said to have a "small six golden formula" and has never been read.
The fourth category, other miscellaneous studies, such as The Book of Wei Zidou, The Original Book of Divination and The Wind Corner, although I have them, I haven't seen them yet, and I can't say anything.
China Book Publishing House has an Introduction to Divination in China, which I read once and talked about many non-mainstream divination methods. Some other methods circulated by the people are reasonable, probably not within the scope of five lines of gossip, or have occult skills, but there may not be books handed down from generation to generation; And the top fairy, into the left, I'm afraid there will be no books.
