Is the authentic fortune-telling for the blind accurate?

Why can the accuracy of folk blind people's fortune-telling reach 100%? And traditional numerology can't even reach 50%? What is the reason?

First of all, there is no 100% accuracy. This kind of thing varies from person to person. There are also many blind teachers who can't learn at home. Traditional numerology is good and accurate, but there are basically no such people in modern times, and there are many fake masters. Second, teachers for the blind have to study hard to make a living and try their best to calculate accurately, otherwise they will not earn money for meals. Those who study traditional numerology are people with vision. If you can't get along, you can change careers, so you may not learn deeply, which is also a big reason. Third, the blind teacher has been inherited for more than 1000 years, and there are many exclusive secrets, all of which are obtained from actual combat and cannot be learned by traditional numerology books.
