What is Taiyi Divine Ding?

It's a good knife. As mentioned in the movie "The Green Beast", Niu Er likes to collect the best knives in the world, and Taiyi Shending is one of his collections.

Taiyi divination is a kind of divination of ancient Han nationality, and it is also called Duijia and Liu Ren. It is an artistic mathematics to calculate the political destiny, luck and historical changes of a country. In the Zhou Wuwang era, the number of hexagrams was "30, 800", followed by Zou Yan's theory of five virtues, which made full preparations for the formation of historical philosophy in Shao Yong. According to the number of Taiyi gods, in ancient times, there was a year from winter to midnight, which coincided with the combination of the sun, the moon and the five stars. When it was designated as Jiazi Year, Jiazi Month, Jiazi Day and Jiazi, it was called Taiji Shangyuan, and the number of years since Shangyuan Jiazi was called Taiyi Accumulated Year. From the accumulated years of Taiyi, the number of hexagrams of Taiyi Liunian and Taisui value is calculated to break the bad luck of each month this year and predict some major political events and natural and man-made disasters. Five Yuan and Six Dynasties were adopted, with 360 years as the big cycle and 72 years as the small cycle. Taiyi stayed in the palace for three years, did not enter the palace, turned around for 24 years, and traveled three times in 72 years. Tai Yi takes one as Tai Chi to give birth to two eyes (subject and object), and the two eyes give birth to the eight generals of subject and object, size and planning. Taiyi is the god of heaven and earth. Taiyi unified the sixteen gods before, knowing storms, floods, droughts and wars. Yesterday's battle between the Yellow Emperor and Chiyou coincided with the fog. Fog books are used to confuse the wind, and compasses are made. It is based on Taiyi Law, which has been circulating for over 3,000 years. Looking at the dragon map outside, playing the tortoise script inside, where is the father and son in heaven and earth? The reason why Yin and Yang are set is obvious. Taiyi knows the number. Taiyi cycles sixty-four hexagrams a week, and your god leads ten fine stars, which makes the longitude and latitude wrong. It is a book. It has lasted for more than 3,000 years, providing a valuable basis for the prediction and decision-making of today's society.
