Why are there 12 zodiac signs in this world, and why are there 12 zodiac signs?

There are many opinions about the origin of the zodiac signs. Some people believe that the zodiac and the earthly branch have the same origin, which can be traced back to the legendary era of prehistory, and the Yellow Emperor in the "Historical Records" "built Jiazi to live for the year", "Da Tuo made Jiazi" is a reflection of this kind of saying, and scholars believe that the Jiazi referred to here is the zodiac sign.

The twelve earthly branches "Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai" represent the 12 zodiac signs "Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, and Pig".

Some people also believe that the zodiac was introduced to China from the Middle East, and the zodiac was formulated by the residents of the Middle East to imitate the Babylonian zodiac, and its introduction to China was when Zhang Qian passed through the Western Regions.

The sexagenary branch corresponds to 12 months.

In the Central Plains region of ancient China, the "Ganzhi Chronology Method" was used, that is, 10 heavenly stem symbols (A, B, C, D, E, G, G, XIN, NON, and 癸) and 12 earthly branch symbols (Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai) were used to match the year. A small number of nomadic peoples in the northwest of our country use animals to keep their dates.

Later, in the exchanges between the Central Plains and ethnic minorities, the two chronological methods touched each other to form the current 12 zodiac signs.

No one in history has determined the exact origin of the 12 zodiac signs, but this kind of contact is accepted by most people.
