Look: We know that fortune telling is just a popular term, and its scientific name should be called "Pi Ba Zi" (this name is the most popular, and everyone knows it) or "Four Pillars Prediction". The theory of Bazi comes from the theory of heavenly stems, earthly branches, yin and yang and five elements. Anyone can master this mysterious method as long as they study. It is not just the blind who can master them. People often say that fortune-telling by blind people is because people who are engaged in fortune-telling among the people are often blind. They have many fortune-telling formulas, but they never record them in writing. They only teach the blind people orally and never pass them on to others. . Therefore, as time goes by, there are fewer and fewer sighted people who know how to tell fortunes. Most of the fortune tellers that people can see are blind. In the past society, the society did not have practical arrangements for the lives of blind people. The basic living requirements of blind people were often not guaranteed, and they could only make a living by their own strength. Because they cannot see, they cannot do many jobs, but fortune telling provides them with an excellent means of making a living. First of all, human beings at any time have a sense of mystery about fate, cannot get rid of the fear of the God of Destiny, and desire to control their own future. This is true for everyone from the common people to the real dragon emperor. As a result, the fortune-telling industry came into being and has endured for a long time. This is the social and psychological basis for the long-term existence of the fortune-telling industry. It is very difficult to engage in social labor or natural science research, but the basic method of correcting the eight characters is much simpler and can be mastered by the majority of blind people. Secondly, although the creation of the BaZi method requires a lot of knowledge of astronomy and geography, once the theory of BaZi is formed, it will be much easier for future generations to master it, and it does not require learners to have to go to high level knowledge. Just know astronomy and geography. This is like the person who originally designed the TV must be proficient in physics, but after the TV is designed, ordinary workers can produce it according to its design drawings. For Bazi Baizi, the judgment rules based on it are fixed, and you only need to remember it once. What changes is only the method of checking the perpetual calendar, and these tasks are not difficult for blind people to complete. Therefore, fortune telling industry It has become a profession passed down from generation to generation for blind people. It can be seen that fortune telling is not just for the blind. People with sight can also tell people's fortunes. Historically, it was the sighted person who created the method of horoscopes, and it was also the sighted people who wrote books on the theory and methods of horoscopes. People with sighted eyes played an important role in the history of the development of horoscopes. played a decisive role.
