What is the formula for the ancients to observe celestial phenomena?

The ancient formula for observing astronomical phenomena:

Stay indoors at sunrise and travel thousands of miles at sunset. There are fish scales in the sky, so you don't have to turn the sun. Chickens stay late, ducks croak, and heavy rain will come soon. Long sunny fog perineum, long rainy fog will clear up. Ants move the snake aisle, and there will be heavy rain tomorrow. Spring fog, summer fog, autumn fog, winter fog, snow.

Dark clouds see the sun and it rains in the middle of the night. Dark clouds have white feet, and there must be heavy rain. Black Huang Yun turned over and hail was just around the corner. Black Huang Yun turned over and was about to lay ice eggs. The low clouds will persist, and it will rain soon. Clouds are long in the northwest and hail in the afternoon. Dark clouds are rising in the high temperature, and hail is about to fall. On the same day, dark clouds began to smoke and hail.

Note: In fact, in essence, astrology, like Taiji, River Map, Luoshu, Zhouyi and Bagua, originated from people's observation of celestial bodies in prehistoric times.

Its original purpose is to infer the solar terms and seasonal changes on the earth and better grasp the laws of nature.

For example, the collision and coincidence of several planets, the surplus and deficiency of the moon, the appearance and disappearance of comets, the rise and fall of the sun, the passing of meteors, and even the outbreak of new stars, as well as the eclipse of the sun and the moon and the aurora phenomenon, all belong to the scope of astronomical observation.

For example, the book Guanzi records:

"bucket handle refers to the east, the world is spring, bucket handle guides, the world is summer, bucket handle refers to the west, the next is autumn, bucket handle refers to the north, and the world is winter."

This is an ancient book 4000 years ago. The concentrated record of these words is to judge the seasonal season at that time according to the position of dusk in the Big Dipper, even now it seems very scientific.

In addition, people can also infer future climate changes by observing astronomical phenomena, such as drought, wind and rain, fog and heavy snow, so as to take necessary measures according to the situation at that time.
