What did the chinese priests use oracle bones for

They also used the oracle bones for divination.

Explanation:

Today divination is considered witchcraft but back then they used the oracle bones for telling the future. They would usually use dead cow bones or dead goat bones and write on the bones with some kind of sharp blade spells and rituals about the future that they saw.
