What are the similarities and differences between the western constellations and the stars in China?

The so-called twelve constellations of the regression time system is that western astrology applies the constellation symbols of traditional astrology to the regression time system

In the regression system, the zodiac is determined by the relative relationship between the earth and the sun, which is different from the stellar system. The orbital plane of the earth around the sun (revolution) is called the ecliptic, and the circle equidistant from the north and south poles is called the equator. The ecliptic plane and the equatorial plane will unfold, and there will be a line on this arc, which is the ecliptic. Both ends (both on the ecliptic plane and equatorial plane) are called vernal equinox and autumnal equinox. The distance between these two points is 180 degrees. Then according to these two points, it is divided into 30 degrees 12 points on the ecliptic, making a total of * * *. This is the zodiac.

There are two systems for the division of the twelve constellations in astrology: one is the regression time system used in western astrology, and the other is the twelve constellations in the sidereal time system used in Indian and Chinese astrology before the Qing Dynasty.

China's sidereal time system was inferred from the "Shi Gan Astrology" quoted by Shen Shi Institute in Wei Desheng during the Warring States Period. Twenty-eight Hostels can be traced back to the Warring States Period in 400 BC. Twenty-eight nights. Every night is an obvious cluster of stars in the sky. Because it is a cluster, it can be used as an indicator of astronomical observation. This is just a difference in the division method. Westerners see 12 constellation, while China people see 28 stars. In fact, they are just classifying the stars in the sky!
