What is the mysterious Qin in history?

Is the ancient Qin Tianjian similar to the modern one? Planetarium? They are all in charge of things in the sky, but there were not many studies on the sky in ancient times, so their substantive duty is often to predict the weather. Some people don't know Qin, but when it comes to some awesome people in Qin, everyone must have heard of it. For example, the two most famous are Li and Liu Bowen. For example, the two most admired textbooks are Sima Qian, who wrote history books, and Zhang Heng, who invented seismograph. Some people may be confused about Sima Qian's appearance. In fact, Sima Qian can not only write, but his achievements in astronomy are no less than his contributions to history books. Moreover, when Qin worked as a part-time editor of history books, Sima Qian was naturally listed.

The role of Qin is often legendary among the people, mainly because of Li and Liu Bowen? Fortune teller? Reason. Li's study of Feng Shui and his prediction of the future have become a system. Even today? He is listed as the originator of grave robbery novels? The reason is not that Li robbed the tomb, but that Li's research on geomantic geography is too high, so he was praised by many people. But to say feng shui, it really has something to do with Qin, a functional department. Because China's study of the sky has a mysterious color since ancient times, which is inseparable from many feudal superstitions.

However, Qin can't be regarded as a department specializing in superstition. In fact, this department's research on the sky has a scientific basis. For example, there are four categories in detail: astronomy, calculation, calculation and missing engraving. It can be seen that the ancients also knew how to collect data first, then sort out calculations, and then get the results, rather than blindly superstitious.

Generally speaking, Qin was mainly a department in charge of the sky, but because the sky was too mysterious, this department was somewhat low-key in ancient times.
