Since Shun Di's time, China has started to use the "chronology of branches and branches" which combines the ten phenomena of heavenly stems and twelve phenomena of earthly branches. The method of zoological chronology originated from nomadic people in the west and north of ancient China. The Book of the Tang Dynasty records: "The Year of the Tiger is bounded by twelve events. If the year is cloudy, it is called the year of the tiger. " Zhao Yi, a famous textual research scholar in the Qing Dynasty, made a textual research in Yu Yu Congkao: "In the early days, the custom of benefiting the north was childless, ugly, yin and hairy, but when rats, cows, tigers and rabbits were divided into years, by the end of the Han Dynasty, it was said that (Khan) money lived in Wuyuan, mixed with Qi people, and spread in China, so it was not abandoned.
The zodiac was first seen in The Book of Songs, the world's first collection of poems. "The Book of Songs Xiaoya Chegong Chapter" says: "At noon on an auspicious day, my horse is insufficient." See also Book of Rites, Monthly Order and Winter Order: "Digging cows for air conditioning." When did the zodiac theory come into being? There is a historical cloud: it should be formed in the Han Dynasty at the latest. Its basis is the cloud in Wang Chong's On the Balance of Things in the Eastern Han Dynasty: "Yin, wood, its birds, tigers. Hey, Tuye, its birds and dogs are also. " Another cloud said, "Good afternoon, Ma Ye. Son, mouse also. Unitary, chicken also. ..... Shen, Qitian also. " * * * Put forward the names of the zodiac. In addition, in Zhao Ye's "Wu Yue Chun Qiu" in the Eastern Han Dynasty, "Wu Zaichen is a dragon." Just added "Chen Long" to complete the zodiac. It can be seen that the twelve zodiac signs were formed in the Eastern Han Dynasty. As for the use of the Chinese zodiac, it appeared at least in the Southern and Northern Dynasties. The Biography of Northern History Yuwen Hu records a letter written to him by Yuwen Hu's mother, which reads: "Your brother was born in Wuchuan Town, the eldest is a mouse, the second is a rabbit, and you are a snake." It can be seen that the Chinese zodiac was widely used by the people at that time to record the date of birth.
However, in the mid-1970s, from 1975 to 12, thousands of bamboo slips were found in the cultural relics unearthed from Qin TombNo. 1 1 in Yunmeng, Hubei Province. Among them, Sunrise Thief clearly records the characters used to predict the appearance characteristics of thieves in the zodiac. The appearance of this miracle proves that the Chinese zodiac has been used in the Spring and Autumn Period and the Warring States Period. Because Qin Tomb No.11 was built in the thirty years of the first emperor, that is, 2 17 BC. Some people say that long before Qin Shihuang proclaimed himself emperor, our ancestors used the zodiac to record the year, and especially pointed out that "it began in summer and spread in Shang and Zhou Dynasties." However, how to quote it remains to be further explored by historians and cultural relics scholars.
During the Southern and Northern Dynasties in ancient China, not only the zodiac chronology was used, but also the twelve zodiac poems written by Shen Jiong appeared:
In the case of mice and dust, cattle and sheep came down at dusk.
Tigers roared in the empty valley, and rabbits opened their windows.
The dragon shadow is far green, and the snake willow lingers near.
Ma Lanfang is far away and breeds sheep in spring.
