Looking up at the sky at night, like a snake, a meteor falls to the north. What do you mean?

Looking at the sky at night, a snake appeared and a meteor fell to the north. When observing the stars at night, Ophiuchus appears in the night sky, which usually indicates a great change in climate.

"Astrology" is the basis used by the ancients to predict good or bad luck. Astrology, like Taiji, Hetu, Luoshu, Zhouyi and Bagua in essence, originated from prehistoric civilization. Those who are proficient in this research often make predictions by observing astronomical phenomena, while others borrow some "astrology" to talk about regime change, which also shows that some changes of human beings can indeed be predicted by observing and interpreting astronomical phenomena.

The so-called "astronomical phenomena" actually refer to some phenomena that occur outside the earth's atmosphere, such as the collision of planets, the profit and loss of the moon, the looming of comets, the appearance of the sun, the passing of meteors, the outbreak of new stars, the eclipse of the sun and the moon and the aurora, and so on, as well as the changes in the operation of some celestial bodies.

Ancient "night sky observation" refers to the similarities and differences between these astronomical observations. Due to long-term accumulation, it is found that a "constellation movement" is actually related to seasonal changes. For example, 4,000 years ago, there was an ancient book called "Pipe" in China, which recorded: "The barrel handle refers to the east, the world is spring, the world is summer, the barrel handle refers to the west, the next is autumn, and the barrel handle refers to the north, and the world is winter." Judging the season by observing the position of the Big Dipper at dusk.

This is talking about "the direction of Beidou bucket handle": pointing to the west means autumn, and pointing to the east means spring. And this method of observing the regular changes of the sky to determine the "four seasons" is called "observing the image and observing the time" because in the era when there was no calendar, this timing method was used by the ancients for a long time and was scientific.
