The ancients often observed the celestial phenomena at night to judge bad luck. How powerful was the ancient people's ability to observe celestial phenomena at night?

In ancient times, night sky observation refers to some astronomical observations, which are actually accumulated over time. For example, the movement of constellations is related to the changes of seasons. For example, the direction of bucket handle like Beidou. When it points to the west, it is autumn, and when it points to the east, it is spring. It should also be the result of long-term observation, which is scientific.

However, we can often hear it from literary works, such as Watching the Sky at Night, which can also be seen in the Three Kingdoms. In other words, Sima Yi said that one star was dim and Zhuge Liang was not alive, and some borrowed stars to say that regime change was a way for rulers to serve their politics.

Many famous military strategists in ancient China predicted the changes of world events by observing astronomical phenomena, such as Sean in the Han Dynasty, Zhuge Liang in the Three Kingdoms and Liu Ji in the Ming Dynasty.

There have been many famous prophets at home and abroad in history, leaving many famous predictions, such as Li and Yuan Tiangang's TuiBei, Liu Bowen's Pancake Song, and French Nostradamus's Century. They all made very accurate predictions about the big events behind them. Most of them are proficient in astrology, and some make predictions by observing astronomical phenomena, which shows that the changes of the world can be predicted through astronomical observation and interpretation, and also shows that the ancients are among them.

Astrology has a history of at least several thousand years in China, but the real history may be more distant. In essence, it, Taiji, Hetu, Luoshu, Zhouyi and Bagua all come from prehistoric civilization.

The ancients believed that "heaven and man are connected" and "heaven and man are one", and we can infer what will happen to human beings from the changes of astronomical phenomena. When people conform to the weather, the "sky" will be auspicious, and the world will be full of crops, good weather and peace. If people go against the sky and do bad things, the "sky" will bring bad omen, and the earth will be dry and rainy, flooded and mutinied. So the ancients attached great importance to the observation of astronomical phenomena.
