Stem and astrology:

According to the knowledge of modern astronomy, we can know that the 28 stars on Sunday are composed of stars, which are very stable in astronomy, their relative positions remain unchanged for thousands of years or even longer, and their influence on the earth is relatively stable;

The earth and other planets in the solar system revolve around the sun constantly, while the whole solar system hovers in the Milky Way at the same position relative to the Polaris (purple and micro stars), which changes the positional relationship between the stars due to the movement of the sun, the moon and the five stars, thus changing the influence of specific stars on the earth and everything on the ground. Therefore, the ancients predicted good or bad by observing the sky at night.
