Is divination in the Book of Changes a feudal superstition?

Yijing has nothing to do with feudalism.

Divination is related to Otawa's superstition, but it is not necessarily superstition.

Your question is like asking: can doctors treat diseases? Almost.

Young doctors are not as good at treating diseases as experienced doctors. Even if they are experienced, they have to be professional counterparts.

The vast majority of people in society are divinatory symbols, which can only be counted as small things, but not as big things.

True numerology masters are rarely accurate. It's just that they understand the ins and outs of this job, so they won't give it to others easily.

I once met a numerologist who said that he had only 15 fortune-telling places in his life. In this life, he counted less than 10 people (all of them are free) and left. Everyone who is calculated by him is grateful to him and regards him as his elder. How many years have passed since he died, and these people still burn paper for him every year.
