Many people who have asked a blind man to tell fortunes feel that his fortune-telling is very accurate. And people who seek fortune telling from those discerning charlatans feel that it is not very effective, so many people do not believe in fortune telling. I have been fortunate enough to meet these people, read a few fortune books, and know some situations. I might as well share my personal views. Perhaps people with some foundation in numerology will find this discussion more appropriate and believe that what I say is true. The most influential traditional fortune-telling in my country is the four-pillar fortune-telling, that is, the eight-character fortune telling. Although ancient fortune books are as vast as the ocean, most people find them very laborious. It’s not that modern people can’t understand it, it’s that those books simply didn’t explain the issue clearly. Unlike Western science, which has prominent themes and a complete system of arguments, it seems to be fragmented and fragmented, with divergent opinions. Some authoritative explanations of numerology are even more confusing. As a result, many people who study numerology have become nerds. Only those with better understanding think of looking for authentic algorithms. Where is the authentic algorithm? I think algorithms that can be verified are very valuable and deserve attention. The folk fortune-telling algorithm used by blind people is quite accurate. They are well-trained. It is said that there is a Valley Sect in Zhangjiajie, and this scripture was transmitted from there. Of course, a blind man does not use books to teach his disciples. Instead, he leads his disciples to recite the verses. He gets up in the middle of the night and recites them again. After a hundred days, he takes the disciples out to train in practice and just give them some pointers. The difference between this algorithm and the fortune book is probably due to the following issues: 1. Ten thousand years pile. Ten thousand years pile is an important fortune-telling formula for blind people. There are two sentences a year. For example, in 84, it is "Jia Zi Bing Yin, the third son of the chu, the second and the fourth." The calculation is derived from the lunar calendar. Jiazi is the year number of the stems and branches of the year, Bingyin is the stem and branch of the first day of the first lunar month of the year, and Chusanzi means the beginning of spring at midnight on the third day of the first lunar month. 24689 The leap ten is recorded in the small month, with twenty-nine days in each month. This year it is a leap ten. Based on this deduction, a person's four pillars and eight characters can be calculated using Liujia, Wushu Dun and Wuhu Dun. According to the twenty-four seasonal hymns, the exact time of each solar term is derived. According to the Tianqian Commander’s use of Shige, we can calculate how many days Wutu is prosperous, how many days Binghuo is prosperous, etc. 2. Children’s birth zodiac sign and related factors. The following is a song to predict the birth sign of a child. The time of birth is: (11-1 pm) Zi, (1-3 pm) Chou, (3-5 pm) Yin, ( 5-7 o'clock) Mao, (7-9 o'clock) Chen, (9-11 o'clock) Si, (11-13 o'clock) noon, (13-15 o'clock) Wei, (15-17 o'clock) Shen, (17- 19 o'clock) You, (19-21 o'clock) garrison, (21-23 o'clock) Hai.
