The origin of the zodiac is very early. At the end of the Warring States period, twelve animals with branches have appeared in the Qin bamboo slips Sleeping Tiger Land and the Japanese Book of Letting Horse Beach. Their names and branches are similar to those of the later zodiac, and their usage and divination logic are also similar to those of the later zodiac. Therefore, it can be inferred that the zodiac signs appearing in Qin bamboo slips of Sleeping Tiger Land and Japanese Fangmatan Book are the embryonic forms of the later zodiac signs.

The zodiac calendar began in the Eastern Han Dynasty. A letter written by Yuwen Hu's mother is recorded in the Biography of Northern History Yuwen Hu, which says: "Your brother was born in Wuchuan Town. The first one is a mouse, the second one is a rabbit, and you are a snake." Explain the folk usage of 12 zodiac at that time.

At first, the origin of the zodiac was mainly to calculate the year number. Twelve kinds of animals are used to calculate the year number of each year, so that people can know more about the change of time and how to calculate their age.

This custom of calculating the year number first appeared in the Eastern Han Dynasty in Historical Records. Because ancient people prefer to mark the year number with tengtu, they choose the zodiac as the zodiac among many animals to customize the year number.

With the development of history, it has gradually integrated into the concept of folk belief, which is manifested in marriage, life, annual luck and so on. Each zodiac has rich legends, forming a conceptual interpretation system and becoming an image philosophy in folk culture, such as the zodiac in marriage and the year of birth. In modern times, more people regard the zodiac as the mascot of the Spring Festival and become a symbol of entertainment and cultural activities.

Apart from China, many countries in the world issue stamps of the zodiac during the Spring Festival to express their wishes for the New Year in China.
