Divination is a mixture of vulgar Confucian classics and theology. Prophecy is a book symbol that uses mysterious argot and prophecy as God's revelation, tells people good and bad luck, and controls the rise and fall of chaos. This kind of superstitious works often have pictures and texts, so they are also called books or books; In order to show its mystery, it is often decorated with some special decorations (such as Wang Mang's synopsis of the Golden Chamber and Liu Xiu's Fu Fu Fu) or dyed in a special color (such as the river map and Luo Shu dyed green), so it is also called "tomorrow" or "Fu You". Weft is an explanation of Confucian classics from the perspective of religious superstition. Because the Scriptures can't be changed at will, in order to deify Confucianism, Shu Wei interprets the Scriptures under the guise of God's will, saying that the Scriptures are the revelation of God. Although the theory of divination also includes some knowledge of astronomy, calendar and geography, most of them are full of theological superstitions. At this time, the combination of Confucian classics and Chen Wei's theory has become a very absurd, cumbersome and vulgar mixture, which has become the ideological weapon of the ruling class and a serious obstacle to the development of science and technology.
At the end of the Han Dynasty, when Yuan Shu proclaimed himself emperor, he predicted that "the generation of Han people painted high" to show its legitimacy.
There is a certain connection between divination and witchcraft, but the main difference is that divination is accompanied by Confucian classics.
