Is it accurate to approve eight characters or divine divination?

Everything is accurate.

Buddhism doesn't mean fortune telling, but drawing lots. It is equivalent to drawing lots and taking chances.

Taoism takes the Tao Te Ching as their sutra, not a fortune-telling book, so they can't.

Fortune-telling books, from the Book of Changes, were originally held by Huang bureaucrats, but now they are held by the people.
