The ancient people believed in various divination techniques, and there were two of them most popular. One was the "divination" using tortoise shell as the material, and the other was the "divination" using old grass as the material. At that time, whether it was a major event for the country or a minor event for the people. All need divination and divination. It reflects the worldview of the emerging feudal class at that time.
As long as there is something wrong with the ancients, they would first ask a question of divination, such as whether there will be rain tomorrow, whether the harvest will be good, whether the war can be won, etc. Then use a drill to drill a small hole and a groove in the tortoise shell (or cow scapula), which is "bu". Then use fire to burn the hole. oracle bone cracks when it is heated, and cracks appear, and this crack is a "cause". What we are talking about today is the "omen" and "omen" come from here, and the word "omen" is the pictographic shape of cracks. The wizard in charge of divination will know the good or bad results after seeing the shape of the crack, and then carve the results on the oracle bones. People must act according to the instructions of oracle cracks, because this is "God's will."
