The race story, what each animal is said to represent, and why the order actually encodes the traditional Chinese double-hours.
The twelve animals are said to have been ranked by a race across a river, organised by the Jade Emperor. The Rat won by riding on the Ox's back and jumping off at the finish; the Pig arrived last, having stopped to eat.
The story is a memory device, but the order is not random. Each animal is bound to a traditional double-hour: the Rat to 23:00–01:00, when rats are most active; the Ox to 01:00–03:00, when farmers historically fed them; the Tiger to 03:00–05:00, when it hunts. Read in sequence, the twelve animals walk through a full day.
The animals also alternate Yin and Yang — Rat is Yang, Ox is Yin, Tiger is Yang, and so on around the cycle. That alternation is why the odd-numbered signs tend to feel outward-facing and the even-numbered ones inward.
