The so-called "dry", that is, "heavenly dry", consists of a, b, c, d, e, g, Xin, ren and decyl crosses; The so-called "branch", that is, "earthly branch", consists of twelve words: zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. The ancients applied the ancient epistemology-"the theory of harmony between man and nature", and thought that there was a corresponding similar relationship between the twelve earthly branches and the zodiac. The specific collocation is as follows: Rat, Ugly Cow, Silver Tiger, Hairy Rabbit, Chen Long, Fourth Uncle, Wuma, Weiyang, God Monkey, Friendship Chicken, Dog and Sea Pig.
The chronology of the zodiac comes from the traditional "branch chronology" in China. For more than 2,000 years, the zodiac has not only become an important part of China folk customs, but also widely involved in various fields of China culture. Painting, sculpture, calligraphy, seal cutting, arts and crafts, ceramics, architectural art … can be seen everywhere. Up to now, the zodiac has become a symbol of love, happiness and good luck. The resulting Zodiac culture vividly reflects China people's world outlook, aesthetic taste and value orientation.
