Can I ching and divination really be accurate?

If you think that Sun Tzu means that he doesn't believe in divination, you are wrong. In the military, we should have the spirit of not believing in divination, and do it because people do it, knowing that they can't do it. When we were defending our country, we had to withdraw our troops after an unlucky divination. That is irresponsible to the country. Just like Jiang Ziya attacked Chao Ge for Zhou Wuwang's divination, the three divinations were unlucky. Jiang Ziya threw the tortoise shell to the ground and said, rotten bones and hay are not credible. Therefore, Sun Tzu, as an iron-blooded military scientist, can't believe everything, so he might as well not believe it. At the same time, on the other hand, this does not prove that divination in the Book of Changes is not allowed. At least as a person who has studied easy to learn for many years, the accuracy of divination is about 85% for the highest level person. Divination is not mathematics, and there is no unified formula, so mistakes are inevitable.
