Is the constellation useful?

You can talk to him about the zodiac! They say fortune telling is not credible! Because the fortune teller first asked to generate eight characters! But what about the constellation? Not the same, I feel that the constellation is useless! The zodiac can at least calculate when this person was born, but the constellation is useless! I hope you don't worship foreign things! ! Not all things handed down from abroad are worthless, but we can't just pursue them! Constellations are useless things! We rural people never believe in constellations! But we don't tell fortune! I just know how to calculate a person's age by the zodiac!
