Why didn't you use tortoise shells for divination after Qin Dynasty?

In fact, the root of this problem is that people's deep beliefs in ancient times have undergone fundamental changes. Divination, in the final analysis, is an activity created by human beings because they cannot explain some strange things happening around them. Predict the smooth degree of some important activities in the future through the cracks in the tortoise shell.

Before the Qin Dynasty, China was in a long period of slavery. During this period, people's inner beliefs are actually very chaotic. At the national level, the rotation of rulers from generation to generation will never be their turn. Even so, the ruler did not explain his sovereignty well and why he had sovereignty. Therefore, the people at that time felt that the world was not dependent, and some unexplained things encountered in life needed to be explained by superstitious means such as tortoise shell divination.

In fact, another reason for the prevalence of tortoise shell divination in that period was the backward level of civilization. Because we modern people have mastered the basic natural sciences such as physics, mathematics and chemistry, we can explain all kinds of phenomena in life well. But at that time, science was not developed, and people knew nothing about the world they lived in, so they pinned their doubts on divination to seek psychological comfort.

After the Qin Dynasty, China entered the feudal period. We should mention Dong Zhongshu, who once advised Emperor Wu of the Han Dynasty to unify the thoughts of the whole country, take Confucianism as the guiding ideology of the country, and bring it out? Sacred right? This theory. After that, people in ancient China began to generally accept Confucian culture and regarded their monarch as the embodiment of Heaven. Although there were still strong superstitions in ancient times, people basically had a basic understanding of the world in which they lived, and they would no longer pin what happened on divination.
