Taiyi's biography is still ancient (A Summary of Shu Tai Yijinjing in Sikuquanshu), which has been written in the Han Dynasty (Twenty-three volumes of Taiyi's Yin and Yang in Hanshu Yiwenzhi have been lost). During the archaeological excavations from 65438 to 0977, a tablet of Taiyi was found in the Ruyihou tomb in Fuyang, Anhui Province, which further confirmed Taiyi's view that "its transmission is still ancient". There are many examples of Taiyi in Twenty-five History (more than 30 cases of Taiyi, six cases of Liu Ren, no exception), which shows that the ancients attached importance to Taiyi, especially the upper class, and paid more attention to Taiyi. This is probably due to the application of Taiyi in military and national disasters. Since modern times, due to various reasons, the ancient culture of China, including the Book of Changes and its prediction techniques, has been impacted unprecedentedly, regarded as superstition and almost abandoned. In recent years, after reflection, people are calling for the return of Chinese studies, and Zhouyi and its Shu Shu theory have also attracted wide attention from people from all walks of life.

According to the examination, ancient officials, such as Si in Yuan Dynasty, Taishi Bureau in Ming Dynasty and Qin in Qing Dynasty, all had full-time officials who were responsible for the research and deduction of Taiyi number, and used it as a social natural disaster forecast, providing important administrative reference and basis for the court and even the monarch.
