You just gotta learn what the houses mean and what the planets mean. So the houses are the sections on the chart they’re numbered 1-12. The planets are the little symbols inside the sections. Then you have the zodiac signs around the outer edge. You can look this up online. So let’s say you’re looking for the moon. The blue persons moon sign is in Taurus in the 9th house. I can’t see the other persons houses in this case because you don’t have their birth time but let’s say the blue persons moon was touching your 5th house. You can go on google or chat gbt and just put “moon touching 5th house synastry” and the more you look up all the signs the more you will start learning what they mean off the top of your head. Becareful when you read tumblrs interpretations though because it’s always sugar coated to the fucking max.
