In ancient times, what was the relationship between rain divination and divination?

In ancient times, astronomical phenomena and animals were usually related to rain divination and divination. Astronomical phenomena include observing the positions and changes of clouds, stars, moon, sun and other celestial bodies in the sky to predict weather and rainfall. The ancients predicted the future weather and rain by observing the changes of astronomical phenomena, thus making arrangements for agriculture and life. In addition, ancient divination often involves animals, for example, by observing the flight, singing and behavior of birds to predict good or bad luck and future events. Animals play an important role in ancient divination, and are considered to be able to transmit mysterious information and predict future changes.
