When did the eight-character fortune-telling begin?

The eight characters originated from Luo Luzi, a hermit in the Warring States Period. He first proposed the method of pushing life by year.

Then Li Bi, Li Faming of the Tang Dynasty, invented the three-pillar method of pushing life, which had a great influence. Then there is the Taoist priest in linen, Li He, the master of the Song Dynasty, who made outstanding achievements in pushing his life. It was the Northern Song Dynasty that really shaped the four-column character. On the basis of Li, the four-column method was invented, that is, the eight-character formula. Then came the Taoist priest in Chen Tuan in the Five Dynasties, the warlock in the Song Dynasty, Xu Zi, Daohong, and Dasheng Xu, and finally came to the Three Life Society. Wan Minying's Tripartite Meeting is a masterpiece. This book was later included in Sikuquanshu by Ji Xiaolan, a great scholar in Qing Dynasty. Nowadays, as long as people learn to push their fate according to the eight characters, most of them watch "Sanyuanhui".
