How to evaluate the accuracy of friends' fortune telling?

This situation exists. But one or two words are not clear. If we can make it clear, people who believe in fortune-telling or those who don't believe in fortune-telling are one-sided. First of all, The Book of Changes has two main purposes: measuring the present situation of people. Tell people what kind of mentality and action they should take in the face of this situation. In fact, the second use is the most precious place in Zhouyi. However, our descendants have infinitely magnified the first use, blindly pursuing the accuracy of calculation, instead of learning the essence of Zhouyi, that is, telling people how to face all kinds of difficulties or peaks in life with appropriate mentality and actions. The most typical example is "infinite achievement", and both Wu He and Tai are the names of hexagrams in Zhouyi. The former describes a very dangerous situation, while the latter describes a stable state, telling people that they are desperate. My friend's eldest brother cut his wrist in despair in April this year and was rescued. Three years ago, his business failed, and the money he earned every year was not enough to repay the loan interest. He felt that he really didn't have a chance to turn over and couldn't hold on. I didn't expect it to resume in June and received a lot of new orders. He is expected to repay the loan this year. If you have a friend who is watching my answer when you are desperate, I hope you must stick to it. As long as people are here, there is hope, and never have the idea of suicide. Sunlight will shine through the cracks in the clouds forever. ? With regard to uses, Zhouyi has evolved a variety of fortune-telling methods, which are collectively called "numerology" in the industry. The theory is complete. There is no essential difference between calculating a person's "destiny" and doing a math problem, and it does not contain theistic content. The so-called good fortune-telling is equivalent to completing a calculus problem with strict reasoning. For details, please refer to the book Yuan Haiziping, Mu, etc., which describes in detail how to play this thing, just as a math textbook tells you the theorem for you to deduce. Through these mathematical skills, we can roughly "calculate" a person's family, innate character, physical condition, good or bad luck, physical trauma and other information.
