Great Liu Ren, together with Daoism and Taitai, is known as the "three types" in ancient times, and has the reputation of "the combination of the three types can communicate with the gods", enjoying the highest position in the history of China's prediction. When the Six Rens came into being, there is no exact textual research. Some people make up their historical background and claim that Liuren originated from Huangdi and Xuan Nv, which is obviously nonsense. During the Eastern Han Dynasty, six people were recorded in Zhao Ye's Wu Yue Chun Qiu and Yuan Kang's Yue Jue Shu. According to the identification of archaeologists, there are several kinds of six-person plates unearthed in Han Dynasty. From this point of view, the generation and popularity of Liuren should be before the Eastern Han Dynasty.
The calculation system of Great Liu Ren is complicated, which consists of the disk of heaven and earth, four books, three biographies, ghosts and gods, etc. It is difficult for ordinary people to learn. During the Warring States Period, Sun Bin, a great strategist and Yi-ology scholar, simplified The Great Liu Ren into four books and five classics, and accurately calculated the good or ill luck of personnel with formulas-this is the golden formula. Sun Bin invented the golden formula and used it to guide marching operations, which achieved remarkable results. This course is called "Six Gods Golden Formula" because it uses formulas to judge things accurately. She was founded mainly to serve military decision-making, taking war as the prediction object, and then gradually flowed into the people to predict the world's Vientiane, and then evolved into a high-level foresight.
