Do you believe in Zhouyi? Especially those eight characters. Why?

Do not believe. Unscientific, illogical, even? In an era without computers, it is definitely impossible to find the laws of everything in the universe. In ancient times, it was always believed that the sky was round, and there was a set of explanations for this. Now, who doesn't know that the earth is round? Maya also said that the world will end in 20 12. What is the result? People, without such great skills, cannot predict the future, nor can they calculate the future of others. In the end, it was just a bluff. Many so-called masters finally make money by publishing books, giving lectures and telling fortune. Why is it not a stock lottery? It's so easy to earn. I can't figure it out. If you travel to ancient times, the era of Zhouyi, your knowledge must be better than Zhouyi.
