What determined the order of the animals in the Chinese zodiac?

The order of the animals in the Chinese zodiac is determined by their place in a mythical race. This legend features the Jade Emperor, who invited all the animals to participate in a race across a river. The sequence in which they finished the race ultimately established their ranking in the zodiac. The first twelve animals to reach the other side were awarded a place in the zodiac, creating the cycle that influences dates and personality traits associated with each animal sign.

This foundational myth not only creates a narrative around the animals but also explains why the zodiac includes a diverse group, each with its attributes that resonate culturally and symbolically in Chinese society. Other options like physical abilities, age, or intelligence do not capture the specific mythical context that explains how the animals were ranked according to their race outcome.
