Is the ancient "astronomical phenomena" true or false? Why are great men born with astronomical phenomena?

The astronomical phenomena are certainly true, but it is somewhat false to explain people's fate with astronomical phenomena. It should be a coincidence that some great men were born with astronomical phenomena, but because ancient people believed in this, everyone spread the word and basically everyone believed it.

Watching the sky at night can be used to judge the weather. There are also modern ones. For example, if you see clear skies and stars in Wan Li tonight, it will basically be sunny tomorrow. Even if Zhuge Liang is a man who knows the astronomical phenomena better, how can a grass boat borrow an arrow? And every dynasty has ministers who look at the astronomical phenomena. Generally, before holding a large ceremony, the emperor will specially summon them to consult the astronomical phenomena in detail. There are even some harem concubines who use the astronomical theory to frame some little princes. Using this to make a fuss can deal a heavy blow to other concubines and princes.

Emperors of every dynasty and generation believed in astronomical phenomena, so ministers who looked at astronomical phenomena were always hot. No matter other courtiers or harem concubines, they will please them appropriately. After all, sometimes if you seize such an opportunity, you may be successful in your career.

In fact, their analysis is illusory, which is completely different from modern precision instruments to observe the sky. Usually, I will judge the situation and observe words and deeds. Many times it's sheer nonsense, just to make the emperor happy. Pick something nice and tell the emperor what you are kidding. And if they are all tall, they will not say that they are not sure, otherwise they will lose their heads.

There are also some people who use astronomical phenomena to cover up their actions. Just like someone rebelled, if you want to be justified, you can prove yourself with astronomical phenomena. Otherwise, even those soldiers won't follow you. After all, this is a matter involving nine families, and it always needs some excuses to support it. So from the astronomical point of view, a little climate exists, since ancient times. But showing a person's fate is unfounded.
