It is said that the ancients looked at the sky at night. How do they predict the future through the change of the sky?

The so-called night astrology actually hides a lot of knowledge and cannot be learned overnight. Ordinary people don't know astrology at all, which is related to your keen judgment. Now if you don't use a telescope or something, you can hardly see the stars in the sky.

I think the main reason why you can see the sky at night in ancient times is that the ancient sky was blue, so you can basically see the constellations below, but now you can't even see the stars when you look at the sky. Ancient astrologers were still very powerful. They can judge good or bad according to the position of Scorpio, Virgo or other constellations in the sky, as well as the position of Mars and the moon.

First of all, let me give you an example of the Qin Shihuang period to let you know what astrology is. There was a strange event during the Qin Shihuang period, when Mars was called Antares. This so-called fluorescence actually refers to Mars. At that time, Mars was called fluorescence, so heart means Scorpio. At that time, Scorpio was composed of three very shining stars, of which the brightest star was called the emperor, and the remaining two hearts were the eldest son and illegitimate child. At that time, Mars moved close to the brightest star. In ancient times, Mars was called a symbol of disaster, which meant that Qin Shihuang's life was in danger. This is what astrologers expect.

But in fact, as far as our current situation is concerned, the so-called Mars staying in Antares is just a strange astronomical phenomenon. This phenomenon has happened 38 times since ancient times, but it has nothing to do with emperors and the like. It's just that ancient astrologers always associated some strange visions of heaven and earth with the life of our emperor, so they regarded it as a catastrophe. So in fact, in ancient times, those so-called people who watched the sky at night often regarded it as a coincidence.
