Supplement: The Zodiac, also known as the Zodiac, is twelve kinds of animals that match the twelve earthly branches in China according to the year of birth, including rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs.

The zodiac is an intuitive representation of the twelve earthly branches, namely, Zi (mouse), Ugly (ox), Yin (tiger), Mao (rabbit), Chen (dragon), Si (snake), Wu (horse), Wei (sheep), Shen (monkey), You (chicken) and Xu (chicken). In modern times, more people regard the zodiac as the mascot of the Spring Festival and become an entertainment and cultural activity.
