The origin of the zodiac
According to Chinese ancient books, in the Central Plains of ancient China, the "chronology of branches and branches" was originally used, that is, 10 heavenly stems symbols A, B, C, D, E, Kyrgyzstan, G, Xin, Ren, Guihe 12 earthly branches symbols Zi, Ugly, Yin, Mao, Chen, Si, and Mao.
In the northwest of China, a few nomadic people use animals to record the years. It is recorded in the Book of the Tang Dynasty: "Tuoba Sinian takes twelve things as the standard. If the year is cloudy, it is called the year of the tiger. " In addition, the History of the Song Dynasty, The Biography of Tubo, also records that when the Tubo leaders narrate, they take events as a chronology. The so-called "twelve old things belong to the day, the year of the rabbit and the year of the horse."
Later, in the communication between the Central Plains and ethnic minorities, the two ways of dating contacted each other, forming the present 12 zodiac. As Zhao Yi pointed out in the Qing Dynasty's Jade Cong Kao, "At the beginning of the custom of covering the north, there was no ugliness on the 12th, but when rats, cows, tigers and rabbits were separated in age, they were spread in China and their ears were not wasted." This explanation about the origin of 12 zodiac has been recognized by many people.
