The real origin of the animal signs in Chinese astrology is not clear.
Legend suggests the creation is attributed to the Yellw Emperor in 2637 B.C.
The Yellow Emperor is a semimythical figure.
Another legend attributes Buddha c.563-c.483 B.C, with the creation of the animal cycle.
Buddha had invited all the animals to visit him but only twelve turned up.
To show thanks, Buddha dedicated a year to each animal throughout history.
The years were allocated in the order the animals arrived.
