If only it were a constellation.

Do people in China believe that constellations are useful?

Your argument is very penetrating.

Western horoscopes say that China's zodiac signs are of the same nature, which means that people use something (Western horoscopes, China's zodiac signs) to distinguish and calculate the date of birth at a certain time, which is not necessarily related to personality, fate, good or bad luck, etc. There are only a few constellations and zodiac signs, but people's fate and personality are so different that they cannot be covered by constellations or zodiac signs.
