People in ancient times knew that something big was going to happen when they observed the astronomical phenomena at night. What can they see?

Since ancient times, Qin has been shrouded in mystery by the world. Some people say that this institution is a ghost, and some people say that this institution can predict the future. So which statement is correct? I think the ancient Qin dynasty could really see some unknown things from the night astrology, such as some weather changes and natural disasters, which can be predicted in advance. Otherwise, the astronomical monograph "Shi Gan Xing Jing" would not be so popular with astronomers.

Qin was an institution in charge of astronomy and meteorology in ancient times, equivalent to the current weather station. The daily work is to forecast the weather. For example, if the emperor wants to go out to offer sacrifices, Qin must guess the weather conditions of that day a few days ago and report to the emperor in time. There are also night stargazing to find out where an earthquake or flood is about to happen, and make local emergency preparations in advance. Special work is to draw calendars and determine solar terms.

So what kind of people can live in Qin Tian prison? People who can enter the Qin Dynasty must be proficient in Yi Li, magic, Five Classics, astronomy, etc. For example, Tang Ruowang, a famous scholar in Qing Dynasty, adapted the current lunar calendar in China according to the earliest lunar calendar used in Ming Dynasty. At that time, he was able to accurately predict the arrival of the eclipse and spread astronomical knowledge in the palace, which was deeply loved by the emperor.

In modern film and television works, we often see Qin's figure. Film and television plays always convey the charm of Qin, and can predict the luck of the country and the fate of individuals. It really seems that one person is above ten thousand people, and sometimes the Ninth Five-Year Plan emperor has to listen to their orders. As a matter of fact, in ancient times, Qin was often only used as an institution to predict the occurrence of meteorology and disasters, not as we saw in the plays, so we must believe that only science can make the country develop better and go further.
