Each animal in the Chinese Zodiac symbolizes characteristics of an individual.
Rats are social and intelligent beings.
Dragons are magnetic and perfectionists.
Sheep are compassionate and determined.
Dogs are loyal and protective.
Whatever your sign is, it marks you as an individual in the Chinese Zodiac. While some traits you may disagree with, the zodiac is pretty accurate.
Think of it as the Greek Zodiac, except with different symbols.
