What do blind people use for fortune telling?

Why is the blind man's fortune telling quite accurate?

Blind Sect was written by Zhang Shibao, the founder of Zhang Shibao. He collected the essence of his hundreds of traditions, compiled a formula and passed it on to the blind. Addendum to the Blind Sect Art Forest was written by Mr. Zhang Shibao, a crown warlock in Ming Dynasty. Since childhood, he has been blindly following, learning easily, being blind and skillful, knowing God's plan, and widely listing articles, which are a collection of all things and are divided into 145 items, from craftsmanship to struggle between the ruling and the opposition, from trivial matters of money to promotion of official positions, pointing to divination tips and explaining divination section by section, so that later scholars can understand it intuitively. Recommend it to friends, test the heavenly heart and study the world. The skill of the blind is to make a living. I believe that its superb skills and rich actual combat are incomparable to most academic schools. Because of historical reasons, Liuyi is not elegant today, so she is called the aunt who respects teachers in blind schools. Blind sects have a systematic idea to grasp hexagrams, including hexagrams, five elements, branches, positions and six gods. The essence of divination is to express personnel phenomena and outline the whole running track of events. Therefore, it is a never-ending process to study the blind Sect. Since the blind Sect left no words, we need to create some conceptual words to study and explore its essence. Of course, some formulas are clever. However, the blind do not use formulas to calculate divination, but use them flexibly under certain conditions. So, don't be rigid. When the blind Sect reached its peak, we called it Sanfa. Today, there are two schools, the academic school and the Jianghu school, which are as light as water and have a clear-cut stand. The theory and method of academic school are discussed in detail in countless books about divination at all times and in all countries. But these discussions are similar and copied from each other. In fact, they can be said that their value is not very high. Up to now, there is still a really excellent work with strong practicability. Historical reasons are not excluded, but there are also some human factors. Due to various objective and historical reasons, the theories and methods of Jianghu School have always been in the hands of a few people. Because of its inheritance and secrecy, it has always been handed down from master to apprentice, and because people who master this theory and method have very strict ideas about choosing apprentices. It is because of this unique way of communication that it is even more mysterious. Most people can only see the magic of its practical application, but can't get a glimpse of its true colors. Compared with the academic school, the theory and method of Jianghu school are more operable and practical.
