According to legend, in ancient times, Fu created Innate Yi (also called innate gossip), Shennong created Lianshan Yi (also called Lianshan Bagua) and Xuanyuan created Guizang Yi (also called Guizang Bagua). We don't know who created Yi before them at the same time. Speaking of it, the above from Fuxi to Shennong to Xuanyuan are all cultural heritages. At present, in the teachings of witchcraft, Buddhism and Taoism, and even among the people, there are still some amazing secret biographies of congenital Yi, mountain Yi, Tibetan Yi and Zhouyi, but there is no special person to collect and sort them out.
It was only in the Zhou Dynasty that the gossip of King Wen was handed down because of the birth of two great figures, Duke Zhou and Confucius, who studied, inferred and explained it. The so-called divination, there is no good or bad luck, it is to analyze and explain people's correct attitude, code of conduct and methods of doing things in prosperity and adversity. Through the inheritance of scholars and ruling classes, King Wen's Zhouyi has become the Bible of China, the source of a hundred schools of thought, and even people's daily life.
