Tai yi Shen Shu za Ji

In ancient China, calendar was closely related to technical mathematics and related to ancient astronomy. Modern scholars have made gratifying progress in trying to decipher the river map and Luoshu from the perspective of ancient astronomy. Taiyi style arranges characters with the nine palaces of Luo Shu, and the relationship between them is very obvious. From the Taiyi map, it is very similar to the Ziweiyuan map at the top of the North Celestial Pole, and the names of Taiyi, Ji Shen, Wenchang, Shijie, Tianyi and Sixteen gods are quite consistent with the names and positions of the stars at the top of the North Celestial Pole. The relationship between Taiyi and paleoastronomy should also be an important discussion topic.

After the Han and Wei Dynasties, in the Northern and Southern Dynasties, "its skills were greatly exhibited in the world". Xixia Wu in the Northern Song Dynasty, "Learn Chinese characters, taste Taiyi Jinjian, and write books for four generations." The great influence of Taiyi School in the history of our country can be seen. As early as the Northern Song Dynasty, there was a view of denying Taiyi style. "Song Shi Liu Fuchuan": "My humble opinion: I will be blessed if I say that I am too divorced. I moved from Wu to Shu in recent years, and I believe what I said. Wei Kun' an blocked it. In today's fifty or sixty states, there can't be more than ten people who are safe. Where is the blessing? Huang Zongxi, a Confucian in Qing Dynasty, thought Taiyi was "confused in latitude and longitude and ridiculous in behavior". Like other ancient mathematics, Taiyi formula has always had people who believe in it and people who are not responsible for it. Two opposing views coexist today.
