The Great Sixth Ring Road, what is it? Why use it to measure things?

Da Liu Ren is a magic number that uses Yin and Yang and five elements to predict good and bad luck. It is a very scientific forecasting method with high success rate, and some even reach the point of unpredictable events. The more proficient we are in it, the more accurate our judgment will be. As the saying goes, "people don't have to ask if they are six years old." The Great Liu Ren contains abundant information in its prediction, and the energy generated by capturing human nature in a certain space-time system greatly exceeds the inherent information source of human beings. The great forecasting principle is based on the changes of the sun, the moon, the stars and the sky, with A, B, C, D, E, Ji, G, Xin, Ren and Gui as ten days, and Zi, Ugly, Yin, Mao, Chen, Si, Noon, Wei, Shen, You, Xu and Hai as twelve days.
