What are the methods of divination in ancient China?

At the earliest, tortoise shells were used for divination. There are many methods: 1, find a live tortoise, carve patterns and characters on its back, and see how wet the patterns and characters on its back are according to the weather; 2. Find a complete turtle shell (the turtle is dead), seal one end and put some copper coins in it, which is similar to asking for a sign.

Copper coin divination, find a certain number of copper coins, usually three, throw them casually and guess things according to the ratio of positive and negative sides.

Shaking bamboo sticks is the most commonly used in temples.

Throw away the bamboo board and find a specific kind of bamboo (what bamboo is forgotten). Dig out the roots, find the best hemisphere, divide it into two halves from the middle, and connect one end with a red rope (some of them are not connected, mainly to prevent them from being scattered during divination), throw them on the ground during divination, and look at the backward shape and static position.
